Special environment-friendly yield-increase organic fertilizer for corn

Abstract

The invention discloses a special environment-friendly yield-increase organic fertilizer for corn, which is prepared from the following raw materials in parts by weight: 9-13 parts of decayed fruit, 12-16 parts of traditional Chinese medicine decoction dregs, 11-15 parts of corn cob, 7-14 parts of urea, 3-8 parts of biotitite, 3-8 parts of perlite, 3-8 parts of medical stone, 12-16 parts of mushroom waste, 0.7-1.3 parts of composite microbial inoculant and 3-7 parts of beet. The special environment-friendly yield-increase organic fertilizer for corn does not pollute the environment, can satisfy the demands for nutrients for the whole corn growth period when being applied once, effectively improves the soil structure, increases the corn yield, has the advantages of labor saving, time saving, higher utilization ratio and the like, and is suitable for most soil in corn belts in China.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special environment-friendly and yield-increasing organic fertilizer for corn. Background technique [0002] Agricultural pollution has become the largest environmental pollution in our country. Now the organic matter content of soil in our country is decreasing from 7% to 11% in the early days of the founding of the People's Republic of China to below 3%. The vicious cycle of the waste caused irreparable losses. Every year in the busy season of summer harvest and autumn, the utilization efficiency of straw and other organic resources is very low. It is often solved by simple and trouble-free incineration, which burns the surface of the soil, wastes resources and pollutes Air pollution, excessive use of chemical fertilizers, undecomposed, and unabsorbed nutrients by plants flow into rivers and lakes after rainwater washes, resulting in excess nutrients in water quality, serious pollution, an...

[0002] Agricultural pollution has become the largest environmental pollution in our country. Now the organic matter content of soil in our country is decreasing from 7% to 11% in the early days of the founding of the People's Republic of China to below 3%. The vicious cycle of the waste caused irreparable losses. Every year in the busy season of summer harvest and autumn, the utilization efficiency of straw and other organic resources is very low. It is often solved by simple and trouble-free incineration, which burns the surface of the soil, wastes resources and pollutes Air pollution, excessive use of chemical fertilizers, undecomposed, and unabsorbed nutrients by plants flow into rivers and lakes after rainwater washes, resulting in excess nutrients in water quality, serious pollution, and extensive use of chemical fertilizers and pesticides. There are hidden dangers. Heavy metal pollution in the soil exceeds the standard. Although chemical fertilizers can supplement enough nutrients for the soil, they ignore the supply of organic matter. If chemical fertilizers are used alone for a long time, the soil will have adverse effects on soil quality and the environment. Under the condition of sufficient organic matter, the aggregate structure is difficult to form, and the adhesion between soil particles is weakened, thereby reducing the water retention capacity of the soil. When the soil does not have enough water, even if the fertilizer quality is high, it is not easy to absorb nutrients in a favorable environment. In addition, the excessive application of chemical fertilizers will also have a serious impact on the environment. When excessive chemical fertilizers are applied, the nutrients that are not absorbed by the soil will be lost with the water. entire ecosystem

[0003] Corn, also known as corn and cob, is not only an important food crop, but also an important feed, medicinal and energy crop. It has tall plants, thick leaves, and well-developed root system. It has a large demand for nitrogen, phosphorus, and potassium throughout its life. Especially the demand for nitrogen. However, in order to achieve high yield of corn, sufficient fertilizer must be topdressed at the seedling stage, jointing stage, trumpet stage, and filling stage. However, topdressing fertilizer at the later stage of corn growth is extremely inconvenient, time-consuming and labor-intensive, and increases investment. cost, not only wasting resources, but also putting enormous pressure on the environment

In addition, due to the long-term excessive input of nitrogen, phosphorus, and potassium in the farmland by farmers, the relative enrichment of macronutrient elements in the soil has been caused, and the phenomenon of relative lack of trace elements has become prominent, which has become a new limiting factor for yield and quality; how to It is currently a technical problem to be solved to prepare a special fertilizer for corn that does not pollute the environment, has sufficient nutrition, does not need to be topdressed after one-time fertilization, and can effectively improve the soil structure and increase the yield of corn.
