Notes on Cucumber Cultivation after Autumn Extension in Greenhouse

After the autumn, the greenhouse cucumber is a cucumber production method that continues to be produced in the cold season of autumn. The early stage of the cockroach is in the high temperature season, while the late temperature is drastically reduced, and the environmental conditions are quite different. The main technical points in the cultivation management are as follows:

 

　　 1, autumn planting seedlings can Cucumber seedling transplanting, may be live, the choice of varieties Zhongnong Zhongnong 12 and 16 and the like. The sowing period should be properly selected. The premature seedling stage is hot and rainy, and the disease is serious; the temperature in the late growth period is difficult to guarantee, resulting in a decrease in yield. Generally, the northern region can be planted from the end of July to August , and the southern region can be planted for 30-40 days. The cucumber seedling stage is under high temperature and long sunshine conditions, which is not conducive to the differentiation of female flowers, and 100 ppm of ethephon solution can be sprayed when the seedlings are 2-3 leaves .

 

　　 2 , planting density greenhouses should be properly planted after the autumn extension. The planting density should be determined according to the variety and the soil strength. Generally, 400 plants per acre are suitable.

 

　　 3 , water management watering should be controlled by two heads to promote the middle, that is, before the melon period, the middle temperature is mainly used to improve the ground temperature, so that we can see the wet and dry; the water is given every 7-10 days during the melon period , each time watering It should be carried out before picking melon to control the madness; after the top melon is finished, the watering is controlled to promote new roots. When the melon is inflated, it should be watered in time. In the later stage, the temperature is lowered, the growth of cucumber is slowed down, and the requirement for fertilizer and water is lowered. In order to reduce the temperature inside the shed, watering should be strictly controlled, and watering is generally performed once every 10-15 days.

 

　　 4, nutrient management in the soil nitrogen supply to ensure that the premise of P and K applied more appropriate. The base fertilizer is generally combined with the preparation of the ground, applying 5000 kg of farmyard manure and 30-50 kg of compound fertilizer per mu . Topdressing is in liquid form and is fertilized with water. In general, the roots of the melons are topped with 15-20 kg of urea , 10 kg of potassium sulfate and 15 kg of diammonium phosphate . In the middle and late stages, the manure can be applied 2-3 times with water . When a large amount of melon is planted, the mixture of 0.3% potassium dihydrogen phosphate and 0.3% urea is sprayed on the foliar surface to increase the yield of the melon.

 

　　 5 , temperature management Cucumber production and development of the appropriate temperature is 25 degrees -30 degrees, more than 30 degrees plant growth is accelerated, easy to grow wild. Therefore, the early temperature is higher, it is necessary to pay attention to temperature control, the greenhouse temperature should be controlled at 25-30 degrees during the day , not more than 30 degrees, and the night temperature should be maintained at about 18 degrees to reduce the respiration and increase the accumulation of dry matter. In the later period, the temperature dropped sharply. The management was mainly based on cold insulation. At the same time, attention was paid to ventilation and ventilation to prevent the temperature from being too high. The disease spread, and the night temperature was lower than 13 degrees. Pay attention to the closed greenhouse insulation.

 

　　 6. When the vines are stalked to about 30 centimeters, they begin to tie the vines. On the first erect abduction, when the vine grows vigorously, it can be bent and abducted left and right. The degree of curvature and tightness depend on the growth of the melon. If there is less time, the curvature will be large and it will be tight.

 

　　 7, after Paul melon cucumber melon, nutrition, plant growth under control. Therefore, try to make the first batch of flowers more sitting. If the first batch of flowers is less than melon, it will lead to madness. According to reports, the use of fruit preserved flowers, spray flowers, can make cucumbers more sitting, and can keep the melon, promote the rapid expansion of small flowers. It can not only mention the morning market, increase the early output, but also effectively prevent the melon from growing. In addition, the pollination effect of bees is also good.

 

　　 8. Harvesting is first of all to see the melons, and the root melons have a significant effect on the melons. When the roots are harvested later, the growth of the melons is limited. The mad long melon should be picked up properly at night to play the role of falling mites, to alleviate the madness. When the growth of the melon is weak, it is necessary to take the roots early to prevent falling, and take measures to promote growth as soon as possible. The harvesting period of autumn cucumber is in a favorable period for the growth of cucumber in warm light conditions, but the optimal environmental conditions are short. It is necessary to make full use of this period to strengthen management to increase the harvesting frequency and obtain high yield.
