High-yield and High-efficiency Cultivation of Cucumber in Large Arch Shed after Autumn

After the fall of the greenhouse, the external environment in which the greenhouse was cultivated was in the early stage of high temperature and rainy season, while the rapid cooling occurred in the later period. With many years of experience, in Heze City, generally lived in the early october of August, and supplied the market from late September to December, which is in line with the supply of autumn and winter helium in the solar greenhouse. About 667 square meters of production of about 4500 kilograms, 667 square meters of effectiveness in about 7,000 yuan, significant social and economic benefits.

Variety selection

Should generally use strong disease resistance, early to high temperature, late and low temperature tolerance, Guagua dense species, such as Jin Yan No. 4, Jin Chun No. 4, Jin Chun No. 5, Jin You No. 11 and so on.

sowing

Sowing period: generally early August.
Seeding method is generally used live sheds, open ventilation after sowing, leaving only the top of the film used to shade rain. In the ridge surface by row spacing ditch, ditch depth 3 cm, pouring enough bottom water, will urge the seeds of buds by 25 cm spacing, 2 to 3 seeds per hole, sowing 1.5 cm after sowing, usually 3 days after emergence , After the emergence of two true leaves after the Dingmiao.

Field management

Temperature and humidity management: In the early days, the outside world was still hot and light, which did not mean the normal growth and development of cucumber. At this time, in addition to the roof buckle film, surrounded by open ventilation, play a cooling effect of shelter, rain. Drop the film when it rains and open it immediately after the rain. It is advisable to cover the shading nets in the sheds, remove them every morning and evening and rainy days, and cover them at noon on hot days. When the cucumber enters the middle of late September to early October in the period of fruiting, the natural temperature adapts to the normal growth of the cucumber and removes the shade net. During the daytime, the temperature in the shed is controlled at 25 to 30°C and during nighttime at 15 to 18°C. When the outside air temperature is 15°C or more, vents must be opened. After entering mid-October, the outside air temperature gradually decreases, and the ventilation volume should be gradually reduced. It should be maintained at 25 to 30°C during the day and 13 to 15°C at night. When the temperature dropped below 10°C in the shed, it was possible to take down the shelf management, cover a small shed in the shed, and extend the period of pod formation. When the night temperature dropped to 5°C, the cucumber no longer grows, and it can be completely pulled.

Plant adjustment

In the early period, attention should be paid to the shelves and vines. The lower side branches should be removed and the male flowers and tendrils should be removed. Lateral branches should be used to increase the yield. When the plant height is close to the roof, topping can be taken to promote the germination of collaterals. When the main cultivar is small, the female flowers on the side branches appear, and then leave two leaves to pick the heart and cultivate the melon.
In addition, pay attention to the control of pests and diseases.
