Fertilization method capable of preventing soil caking

Abstract

The invention provides a fertilization method capable of preventing soil caking. The fertilization method capable of preventing soil caking is specially used for soil covered with crushed straw on theground surface after harvesting and ploughing. The fertilization method comprises the following steps of S1, uniformly spraying a straw degradation agent on the surface of the soil, and then irradiating with natural light for at least 2 days, wherein the using amount of the straw degradation agent is 0.1-0.5 ton / mu; S2, uniformly mixing an organic fertilizer formed by fermenting excrement with amicrobial agent according to the weight ratio of (120-180):1, then uniformly spreading a mixture into the land, then plowing land for 15-25 cm, uniformly spreading a compound fertilizer on the surfacelayer of the soil after ploughing, and covering with soil of 2-15 cm after spreading, wherein the using amount of the organic fertilizer is 1-2 tons / mu, and the weight ratio of the compound fertilizer to an active adsorbent bis (5-8):1; and S3, mixing a nitrogen fertilizer, charcoal ash, humic acid and trace elements in a crop inoculation period, and then carrying out topdressing. According to the method, the soil fertility is effectively improved and soil caking is avoided through reasonable fertilization by utilizing the the crushed straw remained in the field.

Description

technical field [0001] The invention relates to the field of chemical fertilizer application methods, in particular to a fertilization method for preventing soil caking. Background technique [0002] Vigorously developing planting and forestry, increasing crop production and income, and greening the motherland are issues that scientists from all over the world are concerned about. The growth of plants is inseparable from supplementary nutrition. The current planting industry mainly relies on the application of nitrogen, phosphorus, potassium fertilizers and organic fertilizers. To promote the growth of crops, excessive application of chemical fertilizers has a great impact on the quality and flavor of crops, which is not conducive to the development of green agriculture, food safety and environmental protection. Fertilization can not only improve soil fertility, but also an important measure to increase crop yield per unit area. Fertilizer is the most basic and most importa...

Problems solved by technology

The main purpose of these methods is to accelerate the biodegradation of straw by increasing the activity of decomposing straw enzymes. Due to the influence of indigenous microorganisms and changes in the natural environment of farmland, the activity of biodegradation bacteria or compound enzymes applied by external sources has certain fluctuations. There is often a large gap between laboratory and field results, and the cost of farmland application also limits its popularization and application
