The pollution-free cultivation of cowpea is mainly based on protected land cultivation. It is briefly described as follows:
(1) Cultivate strong seedlings: Protected cultivation should use medium-late-maturing, high-yield, disease-resistant, adaptable, and suitable for dense planting. Generally adopting mulching and seeding method can reduce the rooting of injury, and it is beneficial to slow seedlings. Seed processing methods and nutrient soil preparation, bed seedling soil disinfection and other methods are basically the same as kidney beans. Nursery generally adopts the method of cultivating roots and cultivating roots, so as to reduce the emergence of shoots and roots, and is conducive to slowing seedlings and seedlings after planting. The diameter of the nutrition bowl is 8 cm. In the nutrient soil, loose soil and fertile soil that has not been planted with cotton and legume crops within 3 years, 2 pieces of decomposed chicken manure, 2 pieces of horse manure, and 4 pieces of farmland soil are mixed and sifted and packed in the nutrient bowl. . Do not overfill when loading soil. It is best to install 3/4 of the height of the nutrition bowl. Neatly placed on a seedbed. The nursery bed was treated with 50% carbendazim WP 500 times solution or 10% double effect water repellent agent 250 times, and the seedbed was evenly poured.
Before sowing, first pour in foot water. After the water seeps into the water, plant 3 to 4 seeds per nutrient spot and cover 3 cm of nutrient soil. Strengthen the management of seedlings, promptly ventilate the seedlings, control the seedlings, and remove diseased seedlings in a timely manner.
(2) Reapply basal fertilizer, timely planting: Cowpea avoid continuous cropping, it is best to choose plots of cotton and legume crops that have not been planted within 3 years. Before the crop is harvested, the garden field is cleared and the quality of organic fertilizer is 75,000 kg/ha. Mix well with the soil, make rakes or ridges. When planting, apply calcium superphosphate 300 to 4500 kg/ha, grass ash 750 to 1050 kg/ha or potassium sulfate 150 to 225 kg/ha. Mix well and rinse.
Before planting, the greenhouse was sterilized with 50 to 100 times of formalin and 1 to 1.5 kg/m2 of formalin, closed for a day and night, and planted 7 to 10 days after explantation, or 50% carbendazim WP 500 times. Spray disinfection of greenhouse soil, roof and surrounding surfaces.
When planting, the insects are protected against locusts, silver ash film is laid on the ground, and silver gray ash film strips can also be placed around the sheds, with a width of 15 cm.
(3) Cooperate top dressing: After planting, the seedlings are mainly used to control the stems and leaves to grow long and promote reproductive growth to facilitate the formation of more inflorescences. After the scab, combine watering and ditching, chase and apply 15000kg/ha of human excrement or 75~120kg/ha of compound fertilizer, and then apply twice urea for every pod harvested, 75 to 150kg/ha. , Potassium sulfate 75 ~ 120 kg, or top dressing once per pick, the amount can be halved. In order to prevent premature aging of plants, after the appearance of the first peak of production, it is necessary to pay attention to fertilizer and water management, promote the formation of lateral branch germination and lateral flower buds, and make the main inflorescence of the main vine continue to blossom and scab, and extend the leaf age, so that it is the first About 20 days after the second boom, there was a second boom period, which lasted for about 30 days.
Into the prosperous period, can use 0.3% potassium dihydrogen phosphate for foliar fertilizer, prevent premature aging.
In order to promote early symbiotic nitrogen fixation in kidney bean nodules, nitrogen-enriched fungicides can be used to inoculate rhizobial bacteria artificially.

Nitroxinil Injection is indicated for the treatment of fascioliasis (infestations of mature and immature Fasciola hepatica) in cattle and sheep. It is also effective, at the recommended dose rate, against adult and larval infestations of Haemonchus contortus in cattle and sheep and Haemonchus placei, Oesophagostomum radiatum and Bunostomum phlebotomum in cattle.

Contra indications.
