Summer cowpea refers to cowpea that is harvested at a high temperature of 35 degrees. Because of the high temperature, small temperature difference and large amount of rainfall, this cowpea is easy to drum seed and has serious pests and diseases. Therefore cultivation techniques are different from spring. The goal of cultivation is not to pursue high yield, but to be better in commodity quality, stronger in disease resistance, and the color of clips is suitable for the consumption habits of the market. Generally pay attention to the following links.
Summer bean cultivation techniques
First, species selection:
To ensure that the color is appropriate, high temperature is not drum seeds, strong disease resistance, try to choose the type of Feng product.
Second, soil preparation and fertilization:
Mushi 30kg three-element compound fertilizer, decomposed organic fertilizer 2 square. When ploughing the ground, 3% phoxim granules are applied to 7000g to control underground pests.
Third, sowing:
Mu 1.5kg. The density is less than that of the spring species, and 2800 acres are planted, 2-3 grains per hole, and rows of 1.5m are planted in two rows with a spacing of 30cm. Dry seeds are generally broadcast live.
Fourth, seedling period management:
In summer, the seedling period is very short, only about 20 days from emergence to rejection. The main points of management are prevention and control of fertilizers. Normally 10% myclobutanil 40ml is used to irrigate roots to prevent cowpea root rot.
Fifth, climbing frame management:
From vines to full-frame management to control the main control of water, to maintain soil moisture content of 60-70%. Do not fertilize before half full. Pay attention to the prevention of diseases and insect pests, generally use 20% fenvalerate EC. When the rainfall is heavy, it is necessary to spray 80% carbendazim powder and other protective fungicides. When the plant growth point exceeds the pole, it will be topped in time.
Sixth, the period of management:
1, water and fertilizer management should keep up, especially the nitrogen fertilizer to give enough, the general urea 10-15kg urea, applied in 40cm away from the plant, timely watering after application.
2, reasonable and safe use of drugs to control pests. The use of highly toxic pesticides is generally prohibited by the use of highly effective and low-toxic pesticides such as cypermethrin EC and fenvalerate EC.
3, is the prevention and treatment of diseases. Mainly anthrax, leaf spot, and powdery mildew. General use 70% thiophanate-methyl 700-800 times, 80% mancozeb 800 times and other broad-spectrum fungicides, 15% Triadimefon EC 1000 times, to ensure a spray after a spray of medicine.
4. Reasonable use of foliar fertilizer can make pods more beautiful. Commonly used foliar fertilizers are living elements, strong harvest, green tyrants and so on.
