Premature efficient cultivation method of greenhouse vegetables

Abstract

The invention discloses a premature efficient cultivation method of greenhouse vegetables. The method comprises the following steps of step I, constructing a greenhouse; step II, adjusting and controlling environment conditions in the greenhouse; step III, performing anniversary crop rotation arrangement of greenhouse vegetables; step IV, cultivating vegetables in the greenhouse; and step V, controlling diseases and insect pests and physiological barriers. According to the method disclosed by the invention, appropriate vegetable varieties are selected, fertilizer damage, pesticide damage, drought damage and continuous cropping obstruction can be overcome, and the cultivation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for early-maturing and high-efficiency cultivation of greenhouse vegetables. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. Artificially creating a suitable ecological environment, adjusting vegetable production seasons, regulating market demand, and promoting high-quality and high-yield vegetables are one of the effective means to increase farmers' income. Judging from the sur...

AI Technical Summary

Problems solved by technology

The problems caused by fertilizer damage are: first, the growth of vegetable roots is inhibited, and the function of absorbing water and fertilizer is weakened; second, the concentration of soil solution is too high, and reverse osmosis occurs in vegetable plants, resulting in physiological wilting or leaf margin scorching; The first is to emit toxic gas hazards; the fourth is to cause vegetable deficiency disease

[0004] Second, drug damage

[0006] Four, continuous cropping obstacles

The reason for the obstacle is that the same or the same kind of vegetables prefer a certain nutrient element, which is prone to deficiency if the element is not supplemented in time; the second is that the accumulation of soil pathogenic bacteria causes diseases to cause dead seedlings, such as Fusarium wilt and Verticillium wilt; The third is that the root exudates of the same vegetable can easily lead to an imbalance in the structure of the soil microbial community, resulting in soil aging
