Method and structure of greenhouse ventilation water supply and nutrient supplement

Abstract

A method for ventilation, water supply and nutrient supplementation in a greenhouse and its structure, comprising the following steps: a. Ditching: After the greenhouse is prepared, multiple grooves are dug on the ground, and liquid microbial preparations and organic substrates are placed in the grooves to form Organic matrix decomposing reactor; b, pipe laying: bury the infiltration irrigation pipeline system in the above organic matrix decomposing reactor and cover it with soil; c, planting: plant crops on the soil; and d, supplement and adjustment: through The ventilation of the infiltration irrigation pipeline, the supplement of liquid, or the adjustment of environmental factors meet the needs of organic matrix decomposing reactor decomposing transformation and crop growth. The greenhouse constructed according to the above steps has the advantage of making the environment easier for crops to grow.

Description

technical field [0001] The invention relates to a greenhouse ventilation, water supply and nutrient supplement method and its structure, which are especially suitable for the cultivation and production of fruit trees, vegetables, Chinese herbal medicines and vanilla in greenhouses in areas with poor soil and severe cold. Background technique [0002] For crops, the use of fertilizers to supplement soil nutrients to meet the needs of crop growth is a common way to increase crop production. Common chemical fertilizers are quick-acting short-term fertilizers, which have the advantages of easy use and rapid effect. When applied to the soil, they can only Provide fixed nutrients, for example, potassium chloride only provides chloride and potassium ions. However, long-term use of chemical fertilizers can easily cause an imbalance between the supply and demand of plant nutrients, and may also cause groundwater pollution and damage the environment and ecology.

Problems solved by technology

However, this method has the disadvantages that the temperature in the greenhouse and the temperature increase on the soil surface are unstable, and the air holes on the bioreactor are easily blocked, resulting in the difficulty of replenishing air, moisture, liquid microbial preparations, nutrient solutions, and pest inhibitors. Incomplete aerobic fermentation of organic matter in the reactor leads to poor soil warming effect, unstable carbon dioxide concentration and incomplete decomposition
