Special efficient compound fertilizer for chernozem

Abstract

The invention discloses a special efficient compound fertilizer for chernozem. The special efficient compound fertilizer consists of nitrogen, phosphorus, potassium, medium elements, trace element fertilizer raw materials, and composite polyamino acid and salts thereof. The special efficient compound fertilizer is suitable for supplying and supplementing nutrient elements needed by various crops and plants planted in the chernozem. The special efficient compound fertilizer disclosed by the invention is applied once as a base fertilizer, and fertilizer topdressing is not needed in a crop growth process. The produced fertilizer product has effects of remarkably controlling the loss of a nitrogen fertilizer in the chernozem, improving the effectiveness of the phosphorus fertilizer in the chernozem, gathering and activating medium and trace nutrient elements needed by the plants in the chernozem, strongly prompting the crops to absorb various nutrient elements in the chernozem in a balanced manner, greatly increasing the fertilizer utilization rate, increasing the crop yield and remarkably improving the crop quality.

Description

technical field [0001] The invention discloses a special high-efficiency compound fertilizer for chernozem, relates to a high-efficiency chemical fertilizer for chernozem, and belongs to the technical field of agricultural compound fertilizer production. Background technique [0002] In the current agricultural production of chernozem in Northeast China, common fertilizers have a short period of effectiveness, unbalanced nutrient supply, low nutrient effectiveness ratio of fertilizers applied to the soil, serious loss or ineffectiveness, and unbalanced nutrient supply, which is even more unscientific. It is a technical problem where the contradiction between the supply and demand of nitrogen fertilizer and phosphorus fertilizer is more prominent. As a result, the amount of fertilization is too large, and the utilization rate of fertilizers decreases. At present, the overall utilization rate of nitrogen is only about 30%, and the loss of nitrogen volatilization, leaching, and...

AI Technical Summary

Problems solved by technology

[0002] In the current agricultural production of chernozem in Northeast China, common fertilizers have a short period of effectiveness, unbalanced nutrient supply, low nutrient effectiveness ratio of fertilizers applied to the soil, serious loss or ineffectiveness, and unbalanced nutrient supply, which is even more unscientific. It is a technical problem where the contradiction between supply and demand of nitrogen fertilizer and phosphorus fertilizer is more prominent

As a result, the amount of fertilization is too large, and the utilization rate of fertilizers decreases. At present, the overall utilization rate of nitrogen is only about 30%, and the loss of nitrogen volatilization, leaching, and surface runoff is relatively large. Most of the phosphorus in the soil is fixed by the soil and becomes invalid, seriously affecting the absorption and utilization of phosphorus by plants, making the economic benefits of fertilizer application very low, resulting in a huge waste of resources and an increase in agricultural production costs. The gas effect and the eutrophication of the water body are aggravated, leading to the deterioration of the ecological environment

Extensive application and low utilization rate of single chemical fertilizers degrade the quality of agricultural products and affect soil structure and physical and chemical properties

Due to the lack of efficient regulation or the intervention of protective substances, the nutrient supply of fertilizers to plants is unbalanced, causing nutrient stress to the plant growth environment, and at the same time, in chernozem, a large amount of phosphorus is converted into an invalid state in alkaline soil. , leading to a huge waste of resources and seriously affecting the quality of agricultural products
