Organic fertilizer capable of improving fertilizer efficiency of soil and preparation method thereof

Abstract

The invention discloses an organic fertilizer capable of improving fertilizer efficiency of soil, which is composed of the following components in percentage by mass: 5-10% of melon and fruit peel, 2-5% of pig bone, 3-8% of chicken manure, 0.6-1% of eggshell, 0.1-0.5% of Lilac, 0.1-0.5% of magnolia flower, 1-3% of plant ash, 1-5% of balloonflower, 0.5-1% of snail, 0.005-0.008% of onion skin, 3-6% of bean dregs, 10-20% of river sand, 1-5% of hard shell dregs, 1-2% of Irish moss, 2-5% of waste vegetable leaf and the balance of rice washing water. The organic fertilizer disclosed by the invention has the advantages of complete nutrients, reasonable proportioning, reasonable technique, scientific preparation, high crop absorption speed and sufficient aftereffect, can effectively enhance the utilization ratio of the fertilizer nutrients, and can satisfy the nutritional requirements for crops; and the nutrient utilization ratio of the fertilizer is up to 40-50%.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to an organic fertilizer for improving soil fertilizer efficiency and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, residents' demand for safe, hygienic and non-polluting organic and green food is increasing. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. Although general inorganic fertilizers have rapid fertilizer effects, they do not last long. The effect of improving the soil is not great, and even has the side effect of destroying the soil properties. The long-term use of inorganic chemical fertilizers in agricultural production will bring about various problems such as the decline in the quality of agricultural products, soil compaction, and water pollution. Take the black soil area in Northeast China as an...

[0002] With the improvement of people's living standards, residents' demand for safe, hygienic and non-polluting organic and green food is increasing. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. Although general inorganic fertilizers have rapid fertilizer effects, they do not last long. The effect of improving the soil is not great, and even has the side effect of destroying the soil properties. The long-term use of inorganic chemical fertilizers in agricultural production will bring about various problems such as the decline in the quality of agricultural products, soil compaction, and water pollution. Take the black soil area in Northeast China as an example , the soil organic matter has dropped from 8-10% at the time of reclamation to 2-3%, from organic-rich soil to organic-poor soil, and the situation of soil organic matter in other areas is even more serious. It has become a major public hazard in the world today. The current situation of China's target soil resources urgently needs to supplement soil organic matter through artificial measures to ensure the level of agricultural planting and the quality of crop products. Organic fertilizers are rich in organic matter and nutrients needed for crop growth. The required nutrients can improve the soil, improve crop quality, increase crop yield, promote high and stable crop yield, maintain soil fertility, and at the same time improve fertilizer utilization and reduce production costs. Therefore, an organic fertilizer is needed to improve soil fertilizer efficiency
