Greenhouse early-maturing yield-increasing cultivation method for kidney beans

Abstract

The invention relates to a greenhouse early-maturing yield-increasing cultivation method for kidney beans, and belongs to the field of greenhouse cultivation methods for the kidney beans. The greenhouse early-maturing yield-increasing cultivation method is a cultivation method adopted for realizing early maturing and high yield in the whole growth period of the kidney beans. By adopting a simple cold-insulation method through the design of the invention, seedling ages are regular and uniform, and a transplanting period is guaranteed; meanwhile, the labor is saved, and the seedling-growing costis low; the cooling speed and the dehumidifying speed are high, the cooling and dehumidifying effects are good, and the greenhouse is effectively cooled and dehumidified, so that diseases are reduced, and the yield of the kidney beans is increased; and by increasing a walk-in tunnel, the number of covering shed films is increased to 5 layers, namely that the covering shed films include a greenhouse film layer, two top tarpaulin layers, a walk-in tunnel layer and a mulching film layer, so that the transplanting period of the kidney beans in the greenhouse is advanced to the middle of March, and the harvesting starting period is advanced to the middle of May, and the output value is increased.

Description

technical field [0001] The invention belongs to the field of cultivation methods of kidney beans in greenhouses, and is a cultivation method adopted for realizing early maturity and high yield during the whole growth period of kidney beans. Background technique [0002] Nowadays, in raising bean seedlings in early spring solar greenhouses, laying hot wires on the ground is a common method to increase the ground temperature. The main disadvantage is that the bottom of the nutrient pot is heated unevenly, which leads to inconsistent ages of bean seedlings and affects the transplanting period; Labor and cost are high. Nowadays, in the production of bean greenhouses, side wind is mainly used for cooling and dehumidification. The disadvantage of this method is that the speed of cooling and dehumidification is slow and the effect is poor, which leads to serious bean diseases and reduced yield under high temperature and high humidity conditions. Nowadays, in the multi-layer mulchi...
