Water-retention and fertilizer-retention air ventilation nutritional soil

Abstract

The invention discloses water-retention and fertilizer-retention air ventilation nutritional soil. The water-retention and fertilizer-retention air ventilation nutritional soil is prepared from the following raw materials in parts by weight: 20 to 40 parts of garden soil, 15 to 25 parts of leaf mold, 5 to 18 parts of rice chaff ash, 2 to 9 parts of ammonium chloride, 1 to 6 parts of ground phosphate rock, 2 to 8 parts of potassium nitrate, 4 to 10 parts of fish bone meal, 10 to 20 parts of germinated brown rice, 2 to 8 parts of castor meal, 3 to 6 parts of oil residues, 4 to 10 parts of earthworm excretion, 0.01 to 0.06 part of diaminoferric xanthohumate, 1 to 2 parts of sepiolite powder, 2 to 6 parts of grass carbon, 2 to 4 parts of diatomite, 0.5 to 1.5 parts of shell powder, 10 to 20 parts of alfalfa, and 5 to 15 parts of tobacco stem and clay compound. The water-retention and fertilizer-retention air ventilation nutritional soil has the advantages that the degrading rate and nutrient releasing rate can be regulated, the utilization rate of fertilizer is high, nitrogen, phosphor and potassium necessary to the growth of plants can be provided, the releasing rate meets the growth rule of the plants, the slow-release effect is obvious, and the heat stability is good.

Description

technical field [0001] The invention relates to the technical field of nutrient soil, in particular to a water-retaining, fertilizer-preserving, and air-permeable nutrient soil. Background technique [0002] Most of the raw materials used in the nutrient soil for flower seedlings are made of mixed materials such as mountain mud, garden soil, pond mud and humus. These materials have not undergone reasonable ingredients, poor water retention and fertilizer retention, poor air permeability, and easy hardening , the mineral nutrients in it are difficult to be absorbed by flower seedlings, which is not conducive to the normal growth and development of flower seedlings. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a kind of air-permeable nutritious soil that retains water and fertilizer, its degradation rate and nutrient release rate are adjustable, and the utilization rate of fertilizer ...
