High-yield cultivation techniques of cucumber in summer

First, fine land preparation

 

Selected from waterlogging drainage, drought can be poured, breathable field, plowing small rake, with site preparation Mushi 5000 kg organic fertilizer, fertilizer 50 kg, 5 kg multi-element boron, after leveling mounding, Qikuan 1.2 m Sowing after 3 days of exposure .

 

Second, the appropriate sowing

 

Cucumber varieties should be selected high temperature, water logging, disease-resistant high-yielding varieties, live on about May 20, planted two rows of each plot, hole distance 20 cm per bunch planting three seeds per acre seed around 5000 points, after sowing Cover the mulch.

 

Third, field management

 

Melon apical membrane rupture when unearthed immediately; rupture after experiencing dry weather, watering should by trees at night; Qimiao seven days Dingmiao, leaving a robust seedlings per hole, and pouring water, after cultivating more Summer cucumber is shallower than spring cucumber, 4 to 5 cm; cucumber seedlings are inserted into the bracket when they are “squatting”, they should be inserted into the “human” shape frame, tied firmly to prevent being overwhelmed by strong winds and heavy rain, and timely introduction of vines. To prevent entanglement, affect growth, avoid rain splashing the leaves on the soil, affecting photosynthesis.

 

When tying the vines, the vines are evenly distributed on the shelf, and the vines are stretched back to the top of the frame to extend the main vines, prompting the multi-growth, and timely removing the leaf tendrils and the lower old leaves and diseased leaves.

 

Early flowering remove the weeds, the 2nd Row crop before harvest root melon, 2 cm deep.

 

After entering the melon period, summer cucumber grows vigorously, watering and rainfall are more, soil nutrients are easily lost, so it should be more topdressing, watering, watering should be in the evening or in the morning, not watering at noon. In case of high temperature and dry weather, every 1 to 2 days watering 1, 20 kg of urea interlaced mu topdressing. In the case of rain or heavy rain, it is necessary to drain and prevent flooding. After hot rain, it is necessary to timely cool the well water.

 

To extend Guaqi Sheng, increase production per acre available Tianfon element 800 to 1000 times foliar spraying, every 3 to 5 days, spray, spraying may be multiple composite organic fertilizer, was diluted 500-fold, Spray the leaves 3 times.

 

Fourth, pest control

 

Adhere to the "prevention-based, comprehensive prevention" plant protection policy, in addition to the selection of high-resistant varieties and strengthen management, but also early prevention and early treatment, timely medication after the onset. Such as prevention and treatment of diseases, can be used to prevent the occurrence of melon seedlings by spraying with seedlings and dichlorvos; the initial flowering period is 25% sensitized zinc 1500 times solution or 25% chlorpyrifos 1000 times solution or 30% green 400 times liquid suspension , to prevent downy mildew, soft rot, aphids and other pests and diseases; in the melon period should use fast killing spirit, quick killing, killing, killing insecticides, imipenem and other low-residue agents to control pests, spray 75 % chlorothalonil wettable powder 500 ~ 800 times liquid, 1 : 0.5 : 100 half amount of Bordeaux mixture, agricultural streptomycin to control downy mildew, keratosis, etc., before the watering, sprinkle more than 96% of copper sulfate 3kg per acre To prevent the occurrence of epidemics.

 

V. Timely harvesting

 

In summer, the temperature is high, the plant grows fast, and the fruit develops rapidly. Generally, it can be harvested 50 to 60 days after sowing , and the yield per mu is about 3,500 kg. When collecting, it is advisable to collect the diligence early, so as not to fall, generally it is better to harvest the next day. The melon period can be harvested every day to ensure the freshness of the melon and the vigorous growth of the melon.
