The external environment of the greenhouse cultivation in the autumn was in the early stage of high temperature and rainy season, and the temperature dropped sharply in the later period. With many years of experience, cucumbers are generally live in the first few months of August. The market is available from late September to December, and is linked to the supply of autumn and winter oaks in the solar greenhouse. 667 square meters of production of about 4500 kilograms, the effectiveness of 7,000 yuan, significant social and economic benefits.
Variety selection should generally choose strong resistance to disease, early to high temperature, late and low temperature tolerance, Guagua dense varieties, such as Jin Yan No. 4, Jin Chun No. 4, Jin Chun No. 5, Jin You No. 11 and so on.
Seeding sowing time is 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.
In the early period of temperature management, the outside world is still hot and light, which is not suitable for the normal growth and development of cucumbers. 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 between 25°C and 30°C. At night, the temperature is controlled between 15°C and 18°C. When the outside air temperature is above 15°C, open the vents. After entering mid-October, the outside air temperature will gradually decrease, and the ventilation volume shall be gradually reduced. It shall be maintained at 25°C to 30°C during the day and 13°C to 15°C during the night. When the temperature in the shed drops below 10°C, it can be managed by drop frame. A small shed can be covered in the shed to prolong the period of nectar. When the temperature drops to 5°C in the night, the cucumber no longer grows, and it can be completely pulled.
In the early stage of plant adjustment, attention was paid to the upper shelves and vines, the lower lateral branches were removed, the male flowers and tendrils were removed, and the lateral branches were used later 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.
