Detailed explanation of Seedling technique of Cucumber covered with plastic Film

When planting cucumber, using the technology of plastic film mulching to raise seedlings, the main advantage is to maintain the soil temperature and reduce the evaporation of water in the soil, which is very directly helpful to the growth of cucumber. For friends who want to increase cucumber yield, the use of plastic film cucumber seedling technology is very key.

Seed treatment in early stage of ⑴

Soak the seeds in warm soup: put the dry seeds into 55 ℃ ~ 60 ℃ warm water for about 10 minutes, stir constantly, then lower the temperature to 28 ~ 30 ℃ for 4 hours, rinse and accelerate germination.

Chemical disinfection method: soak the seeds with 0.1% carbendazim hydrochloric acid for 1 hour, rinse with clean water and then soak the seeds with clean water for 4 hours.

How ⑵ accelerates sprouting

After disinfection, the seeds were removed and washed, washed, dried, wrapped with cloth, and placed under 27: 30 ℃ to promote germination. The seeds should be turned over frequently in the process of accelerating germination, so that the seeds began to sprout after about 24 hours. When the seeds exposed to the root tip, the temperature could be reduced appropriately, maintained at 22: 26 ℃, and could be finished in about two days.

If the seeds cannot be sown on a cloudy day after germination, the seeds can be wrapped with a wet towel and placed in a cool place for about 10 ℃ to inhibit the growth of buds. This practice is called "squatting sprouts".

Fertilization, sowing and plastic film mulching of ⑶

Before the selection of onions and garlic, beans, leafy vegetables and other crops, the soil layer is loose, fertile, convenient drainage and irrigation of the field. Deep ploughing 15-20 days before sowing, apply 2000-3000 kg of rotten organic fertilizer per mu, rake fine rakes flat and then open ditches to make beds.

Before sowing, make the pond into a flat pond the size of a bowl, with a depth of 8-9 cm, pour enough bottom water, sow 2-3 grains in each pond, and cover the film in time. When the seedlings break their hearts, use a knife to cross the seedlings directly above them.

⑷ topdressing

When the land temperature was stabilized at 16 ℃, the seedlings between rows were removed, and the weak seedlings were removed. The seedlings were topdressing after 2-3 days, and then topdressing once with urea 10-18 mol / mu after 8-12 days.

⑸ irrigation and drainage

Cucumber grows rapidly after sealing film holes, and its water absorption increases gradually. in the early stage, it is mainly to keep the soil moist, and proper watering to promote root growth in the early flowering stage is beneficial to melon growth. Large water and fertilizer management is needed 3-5 days before root melon harvest, and generally irrigated once every 7-8 days. In the rainy season, we should do a good job of ditch drainage and later fertilizer and water management to promote soil permeability and prevent the occurrence of root rot.

Plastic film cucumber seedling technology in the process of operation, we also need to pay attention to the problem of pest control and timely control of diseases and insect pests. In the later stage, we should also pay attention to timely harvest, especially every other day in the full fruit period, which is beneficial to increase the yield.
