Is it difficult to plant dwarf kidney beans in early spring? How to do daily management well?

It is best to plant in early spring. Kidney beans are planted with plastic film in spring, and the sowing period is generally from early April to early April every year. Grain Rain? It is best to sow before the solar term (when the temperature is stable at 10℃ for five consecutive days).

Matters needing attention in planting kidney beans in early spring:

Management of cloudy weather

In case of continuous rainy and snowy weather, the following points should be paid attention to in management: First, remember not to cover the grass curtain or thermal insulation quilt for days to keep the vegetables in a dark environment. Second, don't water it on cloudy days. Third, it is not allowed to spray water pesticides on cloudy days. Continuous cloudy days, due to insufficient light, there is no effective heat supplement in the shed. Simple heat preservation measures can not only raise the temperature, but also the dark environment for days will lead to yellowing of vegetables. The correct way is to open the grass curtain every day even in rainy and snowy weather, so that vegetables can be irradiated by scattered light and maintain the normal activity of chlorophyll. Generally, vegetables can receive scattered light for 4 to 6 hours around noon.

Strengthen thermal insulation, cold and antifreeze.

In winter, the climate is cold and the temperature is low, so it is the key to protect vegetables from low temperature. Multiple mulching cultivation techniques are usually used in production, that is, plastic film is used to cover the ground to increase the soil heat capacity; Covering the straw curtain with a plastic film can prevent rain and snow from getting wet and effectively raise the temperature in the shed. Through such multiple mulching, the temperature in the greenhouse can be increased by 3℃ to 5℃, which has good cold-proof and heat-insulation effects. In case of strong cooling weather, temporary heating measures should be taken (it should be noted that the temperature control should be based on the principle that plants should not be frozen, and the temperature should not rise too high, especially at night).

The cultivation environment of kidney bean in greenhouse is different from that in open field. Because of the high temperature in greenhouse, it often leads to fast growth, and it is easy to appear the phenomenon of long white plant type and less pod setting. In order to improve the yield of kidney beans in greenhouse, the reasonable layout of upper and lower branches and vines of kidney beans can be adjusted by coring.
