A kind of organic fruit and vegetable nutrient soil, and preparation method thereof

Abstract

The application discloses an organic fruit and vegetable nutrient soil, which comprises the following raw materials in parts by weight: 30.2-43.7 parts of coconut peat, 30.2-43.7 parts of grass carbon, 15.1-21.5 parts of vermicompost, 3.1-3.1 parts of vermiculite 4.7 parts, the physical and chemical indicators of the nutrient soil are: total porosity 62.5-74.5%, water content 5.8-34.7%, air-water ratio 1:1.35-2.75, EC value 0.34-2.95mS / cm, particle size 0.07 ~2.35mm. 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 fruit and vegetable seedlings by more than one week, increase the yield of cultivated fruits and vegetables by more than 10%, 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 fruits and vegetables refer to the use of chemical pesticides, fertilizers, herbicides, growth regulators and other substances as well as genetically engineered organisms and their products in the production and processing of fruits and vegetables, but follow the laws of nature and ecological principles, and adopt a series of sustainable development methods. Fruit and vegetable products that have been certified and approved by organic certification agencies and issued organic certificates. [0003] The existing technology has higher requirements for the cultivation of organic fruits and vegetables: for example, the planting soil must be a complete plot without conventional production plots in between. If the plots in the organic fruit and vegetable production base may be affected by adjacent conventional land To...

Problems solved by technology

[0003] The existing technology has higher requirements for the cultivation of organic fruits and vegetables: for example, the planting soil must be a complete plot without conventional production plots in between. If the plots in the organic fruit and vegetable production base may be affected by 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 some organic matter such as crop stalks, sawdust, livestock and poultry manure, etc., are fermented or high-temperature treated, and mixed in a certain proportion to form cultivation substrate materials, the obvious disadvantage is that the maturity rate of cultivated fruits and vegetables is not stable, and the planting effect is low. not good
