The kidney bean is warm and humid, and can grow at an altitude of 2100m to 3000m. The flowering temperature requires 15°C or above. It is cold-tolerant and drought-tolerant. It has low requirements on light, heat, water and fertilizer conditions. It has a wide adaptability and is suitable for planting. The required temperature is 10-15 °C, and the annual rainfall is 850-1000 mm. It is suitable for sandy loam or loam. The soil organic matter content should be above 1.5%, and the soil pH should be 5.5-7.0.
The seeds are manually selected before sowing to ensure the viability, purity and disease resistance of the seeds. Choose full-bodied, brightly colored, disease-free large seeds, and soak for 1 to 2 days.
1. Apply enough base fertilizer
The acre of composted farmyard manure is 2000-2500 kilograms, the biological potassium is 1.0 kilogram, and the phosphate rock powder is 60-80 kilograms. Each farm uses 1.5-2.0 kg of farmyard manure, 0.6-0.8 g of biological potassium, 40-50 g of phosphate rock powder, and is applied to the bottom of the pond as a base fertilizer.

It is not prosperous and the pods are easy to fall, but the excess water will also cause rotten roots. Lands with flat terrain should be cleaned and drained in time to prevent the water from affecting the quality of the weak yellow leaves of cowpea plants.
The above is the high-yield planting technology of cowpea. In fact, the growth of cowpea is relatively rapid. Generally, it can be harvested after 40 days of sowing, and it is also very popular among consumers. Farmers who want to grow cowpea must master the planting technique. Oh.
