Technical reference for planting cucumber in   sunlight greenhouse

   1. Variety selection.

   uses high-quality and high-yield varieties such as local cucumber, Shanghai Yangxing cucumber, and Nongda No.14.

  You can grow off-season vegetables by building a greenhouse. Of modern needs. At present, the demand for greenhouse is constant. Farmers also need to pay attention to some misunderstandings when growing crops through greenhouse. Paying attention to these problems can make the quality of crops grow after the construction of vegetable greenhouse. Need to pay attention to the fertilization of crops. Many farmers believe that the more fertilizer is applied. The growth of crops will be more smooth, although the production of crops can be increased to a certain extent by building greenhouse. However, it is necessary to select fertilizers based on the actual conditions of the crops. You also need to pay attention to the amount of fertilizer input and control the application of fertilizers. If the temperature of the greenhouse is too high, the fertilizer will decompose faster. It will also be counterproductive. Therefore, when growing vegetables in greenhouse, the more fertilizer the better, the use of vegetable greenhouse to grow vegetables can ensure temperature conditions.

  The mounting holes have fasteners. The base has a support bracket. The outer part of the fluorescent lamp is set with a protective frame, which is connected by a connector located in the mounting hole between the two sets of adjacent brackets. Since each bracket has a ventilation hole on the top and a ventilation hole on the top of the ventilation hole, each greenhouse accessory The brackets have good effects. The plate film has an anti-ultraviolet layer, and the top of the plate film has a rolling shutter. This greenhouse has simple equipment, easy installation and disassembly, UV resistance and high stability. The economy is good. Today's waterproof accessories. The steel pipe is a smooth casting, and the bandwidth of the lower port leads rainwater to the outside, effectively preventing rainwater from infiltrating the warehouse; the waterproof ring is made of silica gel. With a certain degree of ductility, the development of facility agriculture, the production of off-season vegetables, and the overall efficiency of agriculture are the only way to realize agricultural modernization. The application in many areas is very.

  Second, cultivate strong seedlings.

  The sowing period of greenhouse cucumbers can be from late December to early and mid-January. It is advisable to use large sheds plus small arch sheds (or large shed electric hotbeds) for seedlings. The seedling age is 40—45 days, and the sowing amount is about 0.1 kg per mu. First put the seeds in clean water, then put them in hot water at 55℃, the amount of water is 3~4 times of the seeds, keep stirring, when the water temperature drops to about 30℃, then soak the seeds at room temperature for 1—2 hours for later use .

   is very easy to mold and rot the parts, thus reducing the carrying capacity. It will fall off and be destroyed, so you must use the hot-dip galvanized greenhouse framework before choosing use, and check and repair frequently during use. Once a dangerous situation is found, you should take reinforcement measures or replace it in time. The daily maintenance of the greenhouse is conducive to its service life. So it should be our attention. Photovoltaic greenhouse, glass greenhouse, solar panel greenhouse, solar greenhouse, sightseeing greenhouse, and ecological restaurant greenhouse. The editor shares several performance indicators that are mainly concerned about the construction of vegetable greenhouse. How to build a good greenhouse, in addition to using high-quality raw materials outer. In the construction, we should also focus on some performance indicators, based on its service life and use effect. 1. Light transmittance, the greenhouse is a lighting building. Therefore, the light transmittance is a basic index for evaluating the light transmittance of a greenhouse.

  Three, timely planting.

   canopy covered small arch sheds with mulching film, straw curtain cultivation, in mid-February to early March, when the seedling age is 40—45 days, the plant height is 15-20cm, and there are 5—6 true leaves. Generally, two rows are planted per border, the row spacing is 40~60cm, and 2500-2700 plants are planted per mu. ncdkjlsddf

  Four. Strengthen field management.

  1, fertilizer and water management. Half a month before planting, the base fertilizer is applied in the furrow, 1500 kg of fertilizer per mu, 1000 kg of human excrement and 45 kg of compound fertilizer. After planting live trees, 1000 kg of human feces and urine are applied per mu, and top-dressing is performed 15 days later. Cucumbers grow fast and the supply of fertilizer and water should be timely. The fertilization method adopts the principles of "thin fertilizer and frequent application" and "small amount of meals". Generally, topdressing is performed every two harvests. Keep the soil moist throughout the whole life. After the fruiting period, according to the soil moisture content, water once every 1—2 weeks.

  2, temperature control. After planting, keep a high temperature in the shed to help slow down the seedlings. Measures such as heat preservation, antifreeze and ventilation, and protection against heat and burn should be strengthened after the slow seedling. Generally in sunny days, the temperature in the shed during the day reaches 28 & mdash; ventilate when the temperature reaches 30℃; in cloudy days, properly ventilate, keep the temperature around 20℃, and the shed temperature at night is 15℃ (not lower than 10℃). Uncover early and cover late to light. Generally, the small arch shed is removed before the vines are erected, and the side film of the big shed is removed in late April, and the top film remains until the end of the harvest.

  3. Use Baoguoling 100 times solution to spray flowers and fruits during the initial flowering period, and the output will be in the previous period.

  5. Pests and diseases.

  The main diseases are downy mildew, blight, fusarium wilt and disease. It is necessary to implement agricultural measures such as paddy and dry rotation, and spreading quicklime to prevent the occurrence of diseases. Pay special attention to the early development of downy mildew. Cucumbers in greenhouse generally start to occur in mid-to-late March. When the temperature rises to 20°C to 24°C after Qingming Festival, it can quickly spread to Manyan. Therefore, starting from mid-March, spray with 25% carbendazim or 70% Antaisheng or 58% Ruidu mould every 5-7 days; after downy mildew spots appear, use 72% Kelu 750 times liquid or 69% Anke 600 times liquid. In rainy weather, 45% chlorothalonil fumigant can be used at 0.2 kg per mu. Close the greenhouse for smoke in the evening, ventilate the next morning, and use it alternately with spraying. Insect pests are mainly aphids, you can use Kang Fu Duo 7000 times liquid or once net 2500 times liquid.

  Early spring greenhouse cucumber planting technology

   Early spring greenhouse cucumbers are planted in some old vegetable areas due to the large planting area and repeated cropping year after year, resulting in the occurrence of cucumber wilt and blight, which constitutes the production structure of greenhouse cucumbers. We adopted comprehensive measures such as cucumber grafting and raising seedlings and temporary heating of the fire, which effectively solved the problem of soil-borne diseases and improved the economic benefits of cucumber planting.

  1. Choose protected cucumber varieties

   Shandong Misi, Xintai Misi, and Jinchun 3 are resistant to low temperature and high temperature, and the melons are dense, which are very suitable for greenhouse cultivation in early spring.

  2. Grafting seedlings

  The water content of the artificial seeded substrate is kept at about 35%. Second, sowing to promote germination, 1, sowing. Adjust the hole punch on the seeding production line to a hole depth of about 08cm. Manual punching can make a simple puncher. Make the hole depth the same, and the seeding hole is too shallow. Seedlings are easily unearthed by "wearing a hat". The seeds are sowed in a dry manner. Before sowing, the seeds should be selected and the seeds with full grains should be selected. After sowing, cover all the seeds with vermiculite, and then scrape the surface of the plugs to prevent the seedlings from unearthed by "wearing a cap". 2. Watering, adjust the amount of irrigation machine on the planter production line to the required amount of water. The watering amount for each plate of 105-hole seedling tray is about 04~, and the amount of water for each tray of 72-hole seedling tray is about. The amount of artificial irrigation required to reach 1/3 of the moist seedling cultivation substrate. 3. Accelerate the germination, put the watered seedling tray on the germination vehicle and push it into the germination chamber for germination.

  The cucumber planting time is in mid-January, the calendar seedling age is about 50 days, and the seedling age is 5 or 6 leaves and 1 heart. The rootstock is black-seed pumpkin. The scion is sown 3 days earlier than the rootstock. Before sowing, both the rootstock and the scion seeds need to be warm-blanched, and then sown in the stove ash with perlite or sawdust soaked in hot water and some nutritious soil. Box or plastic tray. The grafting method is abdominal incision grafting, and its big advantage is that the cucumber seedlings can be of any size. After grafting, small arches are buckled in the greenhouse and covered with grass thatch for shading management.

   There are mainly two types of bamboo and steel pipes. The common ones are bamboo and wooden sheds. The ceiling size glass greenhouse vegetable greenhouse use bamboo as the basic material, with a height of about 2 meters. With a width of 4 meters, this material shed. The general service life is about 3 years, the steel shed, the height is 22 meters. The width is more than 6 meters, and the general service life can reach 15 years. Vegetable varieties, greenhouse vegetables are only suitable for the selection of spring tomato varieties, so the utilization rate of the greenhouse is greatly reduced. But the cost of growing winter vegetable varieties is higher. But production efficiency cannot. After autumn, early winter and spring, there are more choices when growing vegetables. Such as cabbage, tomatoes, cucumbers, broccoli, eggplant, green peppers, red peppers, lettuce, spinach, onions, green beans, green peppers, onions, green beans, lentils, etc., shading and rain proofing, the key to growing vegetables in a solar greenhouse is shade.

   The lack of water reduces the yield, and the fruit does not grow in size. It should not be too much. The amount of water is 50kg per tree, and the saplings should be watered to 30kg, which means that the whole period of cherries from flowering to before harvest is mainly small water. Do not pour flooding water. Especially in the hard-core period of cherries. Watering large amounts of water will cause serious yield reduction. After the fruit is harvested, water a large amount of water to replenish the water content of the tree. How to judge the water content of the field? The soil method should only hold the soil with your hands. There are traces of wetness, then the moisture content of the soil is 80% to 90%. If you hold the soil and feel moist, it will be 70% to 80%. If you hold the soil without moisture, it will be less than 50%. This method depends entirely on feeling, and can also be measured with a soil moisture meter. In short, keep the ground moist during production. Mainly small water.
