Organic nutrient soil for fruits and vegetables, and preparation method for organic nutrient soil

Abstract

The application of the invention discloses organic nutrient soil for fruits and vegetables. The organic nutrient soil comprises the following raw materials in parts by weight: 30.2-43.7 parts of coconut bran, 30.2-43.7 parts of grass carbon, 15.1-21.5 parts of wormcast and 3.1-4.7 parts of vermiculite; the nutrient soil has physical and chemical indexes that the total porosity is 62.5-74.5%, the water content is 5.8-34.7, the air-water ratio is 1:1.35-2.75, the EC value is 0.34-2.95mS / cm, and the particle diameter is 0.07-2.35mm. The organic nutrient soil disclosed by the invention has the advantages that the air permeability and the drainability of plant materials can be improved, and relative temperature is maintained for promoting sprouting. The growth cycle of seedlings of fruits and vegetables is promoted to advance by more than one week, the yield of cultured fruits and vegetables is increased by more than 10%, the quality can be improved, the dietary value is increased, the development of root systems of vegetable crops is good, and the vitality of the vegetable crops is enhanced; the water absorption capacity and the fertilizer absorption capacity are improved, overground parts grow at a high speed, and the chlorophyll content of leaves is increased.

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
