Compound soil conditioner and preparation and use method

Abstract

The invention discloses a compound soil conditioner and a preparation and use method. The compound soil conditioner comprises the following raw materials by mass percent: 40-60% of decomposed organicfertilizer, 10-20% of fulvic acid, 15-20% of edible mushroom dreg or biogas residue, and 15-20% of a compound microbial agent. The raw materials of the compound soil conditioner are rich, the formulais simple, the cost is low, the effect is good, and the compound soil conditioner is suitable for various types of soils and is convenient for large-area agricultural popularization and application. The compound soil conditioner effectively improves the soil and the soil fertility, the content of organic matters in the soil is increased, the microelement is better promoted to be absorbed by a plant root system, the adverse resistance of the plant is improved, the development of the plant root and the action of the beneficial bacteria are promoted, the ecological environment of the soil is improved, the use amount of a fertilizer is reduced, the utilization rate of the fertilizer is increased, and the quality of an agricultural product is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural soil fertilizers, in particular to a compound soil improver formula and its preparation and use methods. Background technique [0002] Due to the long-term application of chemical fertilizers, the shortage of organic fertilizers, and the imbalance of various nutrient ratios, the ecological environment of farmland, soil physical and chemical properties and soil microbial flora have been damaged to varying degrees, which directly affects the safety of agricultural products. The long-term use of chemical fertilizers leads to continuous acidification of the soil, saline-alkali compaction, reduced soil fertility, insufficient fertilizer and water retention capacity, slow plant growth, poor stress resistance, and reduced product quality. At the same time, the input of chemical fertilizers is increasing, the production cost is increasing, and the agricultural ecological environment is becoming more ...
