How do green beans achieve high yields? What are the requirements? In fact, the green beans can be called cowpea, which can be planted in both the north and the south of China. Today, the small series of Huinong.com will take everyone to learn the cultivation conditions of green beans. I. Soil and nutrient requirements In the production process of green beans, the soil is deep and soft, and the soil is preferably rich in humus and has good drainage. Green beans can grow in sandy loam, loam or general clay, but they should not be cultivated in low-humid and heavy clay soils. The pH value of the soil is generally 6-7, that is, it is not suitable for over-acid or over-alkali. The absorption of nitrogen and potassium fertilizer is more in the process of planting the green beans, and a certain amount of calcium fertilizer is needed, and the phosphate fertilizer is less absorbed. Second, the water demand The roots of the green beans are developed, and there are many lateral roots, which are more drought-tolerant and less resistant. Seed germination needs to absorb enough water, but the water is too much, the soil is dehydrated, and the seeds are easily rotted. The suitable field holding capacity of the plant growth period is 60-70% of the maximum water holding capacity. The water requirement during the flowering period is strict, and the suitable relative humidity of the air is 65-80%. Third, lighting needs It is a short-day plant, but different varieties have different responses to the photoperiod. They can be divided into three categories: one is photoperiod sensitive, the other is photoperiod-insensitive, and the third is photoperiod-sensitive. Fourth, temperature requirements Green beans are a kind of crop that prefers warm but not frost-tolerant weather. The germination temperature of seeds generally needs to be kept at 20 to 30 degrees, and it is impossible to germinate below ten or forty degrees. The above is the high-yield planting requirements for green beans. Do you have any points to add?
