Organic fruit and vegetable nutrition soil and preparation method thereof

Abstract

The application relates to an organic fruit and vegetable nutrient soil, which is made of the following raw materials in parts by weight: 30.2-43.7 parts of coconut peat, 30.2-43.7 parts of peat, 15.1-21.5 parts of cow dung, and 3.1-4.7 parts of perlite. The physical and chemical indicators of nutrient soil are: total porosity 45.6-68.5%, water content 6.7-27.3%, air-water ratio 1:1.35-2.75, EC value 0.34-2.95mS / cm, particle size 0.08-2.15mm. The invention has the advantages of improving air permeability and drainage of the plant material, maintaining relative temperature and promoting germination. Promote the growth cycle of vegetable seedlings by more than one week, increase the yield of cultivated vegetables by more than 12%, and improve the quality and edible value of vegetable crops. The root system of vegetable crops is well developed and the vitality is enhanced; the water and fertilizer absorption capacity is increased, and the growth rate of the aboveground parts is fast. Increased leaf chlorophyll content.

Description

technical field [0001] The invention relates to an organic fruit and vegetable nutrient soil and a preparation method thereof Background technique [0002] Organic vegetables refer to the pure natural green vegetables cultivated in strict accordance with the organic production procedures in the vegetable production process without using any chemically synthesized pesticides, fertilizers, herbicides and growth regulators. [0003] The existing technology has higher requirements for the cultivation of organic vegetables: for example, the planting soil must be a complete plot without conventional production plots in between. If the plots in the organic vegetable production base may be affected by adjacent conventional land To avoid the impact of block pollution, a buffer zone or physical barrier must be set between organic and conventional plots to ensure that organic plots are not polluted. Therefore, the cost of use is relatively high, and it is not easy to promote and appl...

Problems solved by technology

[0003] The existing technology has higher requirements for the cultivation of organic vegetables: for example, the planting soil must be a complete plot without conventional production plots in between. If the plots in the organic vegetable production base may be affected by the adjacent conventional land Due to the impact of block pollution, buffer zones or physical barriers must be set between organic and conventional plots to ensure that organic plots are not polluted, so the cost of use is high, and it is not easy to promote and apply

In addition, although there are some cultivation matrix raw materials that use organic matter such as crop straw, sawdust, livestock and poultry manure, etc., after fermentation or high-temperature treatment, and mixed in a certain proportion, the obvious disadvantage is that the maturity rate of cultivated vegetables is not stable, and the planting effect is low. not good
