Nutrient soil

Abstract

The invention provides nutrient soil, which includes the following raw materials by weight: 50-100 parts of decomposed farmyard manure, 30-60 parts of subsoil, 10-20 parts of acdified kaolin, 20-50 parts of acidified sludge, 20-30 parts of leaf litter, 15-20 parts of a wheat bran-rice chaff mixture, 7-10 parts of tung tree seed bran, 12-15 parts of slaked lime, 5-15 parts of high viscosity attapulgite clay, 1-5 parts of fast soluble sodium silicate, 1-3 parts of hydroxypropyl methyl cellulose, 1-10 parts of crushed plant fiber, 2-15 parts of crushed peat, 1-5 parts of expanded vermiculite, 1-5 parts of acidified expanded perlite, 1-5 parts of high water absorption resin, 5-10 parts of a compound microbial inoculum, 5-10 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 5-10 parts of fatty alcohol polyoxyethylene ether, 47-130 parts of gravel shaped attapulgite flower ceramsite, 5-15 parts of humic acid, 15-20 parts of avermectin dreg, 3-5 parts of soil yeast granules, and 3-6 parts of gypsum. The nutrient soil provided by the invention can obviously promote plant growth, can increase the plant height by an average of 32.1%, increase the stem diameter by an average of 8.9%, and increase the crown diameter by an average of 44.1%.

Description

technical field [0001] The invention relates to the technical field of nursery stock cultivation, in particular to a nutrient soil. Background technique [0002] The technology and method of seedling planting should be widely used in garden engineering. In order to improve the ecological environment, my country has successively launched key projects such as Tianbao, Sanbei, and returning farmland to forests in the past ten years, and the forest coverage rate has increased year by year. In terms of forestry afforestation, since key projects with good site conditions have been given priority, most of the remaining implementation plots are arid places with poor site conditions. In the seedling raising and planting of seedlings, the root system of seedlings cannot grow healthily due to geological soil compaction, poor water permeability or insufficient nutrients, which poses unprecedented difficulties for forestry. [0003] Nutrient soil is a soil specially formulated to meet ...

Problems solved by technology

Generally, it is prepared by mixing fertile field soil and decomposed manure. There are also nutrient soils selected from imported high-quality peat and coconut bran mixed in a specific proportion. However, these nutrient soils have not undergone reasonable ingredients and strict disinfection. Conducive to the normal growth and development of seedlings
