First, choose a good species
Large, full, shiny, non-insect-eye and mechanically damaged cowpea varieties should be selected to remove pods, granules and impurities, and to select seeds with strong vitality.
Second, choose to cultivate fertilizer
Kidney beans are most suitable for growing in a cool, 1900-2,500 meter area, requiring loose soil, deep soil, and neutral loam and sandy loam with a pH of 6-7. Mu farmyard manure 2000-2500 kilograms with 40-50 kilograms of phosphate fertilizer mix, plowing a uniform plow into the ground. When planting Mushi three 10% N? P? K compound fertilizer 20 kg for the bottom of the fertilizer.
III. Biological potassium seed dressing
Kidney beans are phosphorus and potassium crops. Potassium fertilizer can effectively increase cowpea production. The method is to mix beans with appropriate amount of fresh cow dung first, and mix 1-2 packages (1 kg/pack) of biological potassium with beans.
Fourth, timely sowing, rational close planting, standardized planting
The optimum sowing period for cowpea is the Qingming-Guyu season, and the sowing is completed by May 10 at the latest. Ridging and reclamation planting, rowing distance from 3 to 3.53.5 feet, about 1100 to 1400 ponds per mu, sowing 3-5 pellets per pond, leaving 2-3 strains between seedlings, 20-22 kg per mu, Appropriate early broadcast and deep broadcast.
V. Timely cultivating, fertilizing, plugging, and cutting
After the emergence of seedlings in a timely manner, check the seedlings to make up for lack of replenishment and replenishment, cover the top vines. When the bean seedlings grow 2-3 moss leaves, and the time seedlings fertilizer, Mushi fertilizer compound fertilizer 10-15 kg, and the first cultivator rake, leaving 2-3 strains per pond. When the seedling is about 1 foot tall, perform the second time and insert the rod. Flowering period with organic key fertilizer 50 grams / mu watered 60 kg spray. See the soil and seedlings at the end of the crop period and follow the appropriate amount of nitrogen fertilizer. When the bean is up to 2 meters in height, the top is tipped and the extra side branches are cut off at the flowering stage, and the lower leaf is destroyed.
6. Pest control
The main diseases of cowpea in our county are root rot, rust, and anthrax. The pests are mainly tigers, pods, aphids, and whitefly. Insect pests are mainly seedlings with ground tigers and leaf-eating insects. They can be sprayed with 1000-times of trees. During the flowering stage, soybean locusts are mainly used for pesticides such as cyanobacteria, insecticides, etc., and cowpea root rot is at the seedling stage. The spray was sprayed with 70% thiophanate-methyl 1000-fold or 50% carbendazim 4000-fold and sprayed 2-3 times continuously.
Seven, timely harvest
The maturity period of cowpea is inconsistent and usually matures gradually from bottom to top. When the leaves fall yellow and the soybean meal gradually turns yellow, they are harvested in batches from bottom to top, dried in shells, dried, and then threshed to ensure the quality of the beans and improve the goods. rate.
