The seedlings of late-fruiting cucumbers are suitable for the period from mid-late July to mid-August. Generally, seedlings are grafted. Commonly used rootstocks are black-skin squash. Cucumbers were sowed earlier than the pumpkin for 3-5 days. When the cotyledons of the pumpkin seedlings were unfolded and the true leaves were exposed, they were grafted.
For planting and planting for the first 15 days, 8-10 cubic meters of organic fertilizer and 60 kg of ternary compound fertilizer are applied. After the fertilization, fine soil preparation is performed and the shed is sterilized. Then the ground is made into small sorghum, and the width is 0.8-1.2 meters. Row. Seedlings grow 2-3 true leaves when planting, 1800-2000 strains per acre.
When the temperature management is planted, the shed is first transplanted after the shed, pay attention to ventilation and shading, and when the outside temperature drops to 14°C-16°C, cover the grass rake. The daytime temperature was maintained at 25°C-28°C after easing the seedlings and maintained at 14°C-20°C during the night.
The temperature of the fertilizer and water management after planting is relatively high. Watering and cultivating in time are required to promote root growth. In the guava period, water is poured once every 3-5 days, and fertilizer is chased after each watering. Appropriate control of water and fertilizer after entering the cold season, as the temperature decreases, the watering interval can be properly increased to 10-12 days. After entering the harvesting period, 20-30 kg of compound fertilizer and 20 kg of urea are applied with watering MUS, and a 0.3% potassium dihydrogen phosphate solution is sprayed once every 7 days for the squashing period. 8-10 days application of a fertilizer.
Adjusting the delay of the plants The cucumbers are prone to lengthiness. They must be put on shelves or vines in a timely manner. The side branches should be removed. When the rootstocks of the rootstocks are sprouted, they must be removed in time. The tendrils must be removed in time before entering the results. When female flowers are too much or when flowers appear to be topping, part of the female flowers must be removed, and female flowers and young females that have already differentiated must be removed in time. After entering the fruiting squash, the vine spreads promptly and leaves 15-16 green leaves for each plant after falling. Remove tendrils and melons when falling, and remove some of the female flowers. Cucumber grows for a long period of time without the need for a topping at the time of cultivation. When the top heart breaks, it can be replaced by 1-2 branches from the bottom. Careful attention should be paid to the timely removal of old leaves, yellow leaves and diseased leaves.
To improve the light conditions for the cucumber plants to fully see the light, it is necessary to properly expose the late Ganoderma lucidum. In order to enhance the lighting in the shed, aluminum-plated polyester reflective screens can be hung on the back wall to remove dust, grass and other contaminants from the film. In the case of cloudy snow, it is not possible to cover the grass. When there is heavy snow, we must cover the grass and then cover it with a layer of anti-snow film. However, after the snow stops, remove the anti-snow film and uncover the grass immediately. Conditional fluorescent lamps can be installed in the greenhouse to maintain a distance of one meter from the crop, and 2-3 hours of light should be filled every morning on a cloudy day. Even when the weather suddenly turns cloudy after a cloudy day or in the snow, it should be revealed in an alternating manner to avoid rapid wilting and death.
Diseases and Pests Control Cucumber diseases and pests mainly include downy mildew, powdery mildew, bacterial keratoderma, and blight, and insect pests include leafminers and aphids. For downy mildew can be used 800-1000 times liquid prophylazine or cream rick spray control; can be used for bacterial keratoses 4000 times streptomycin spray of agricultural control; on wilt disease can be in the seedling period every 7 days About 500 times the carbendazim irrigation root. When larvae occur, they can be sprayed with 1500-2000 times of ephedrine, and in the case of locusts, they can be sprayed with 2000-times of Nanon Bimo.
Harvesting cucumbers in autumn and winter should be harvested early when it grows weak, and can be harvested properly when growth is strong. After the temperature is lowered, it must be lightly harvested and harvested appropriately. Overwintering and picking cucumbers should be harvested early, due to low temperature and short sunshine time during the growing season, and appropriate thinning and thinning of fruits.
