Rice planting synergist

Abstract

The invention discloses a rice planting synergist. The rice planting synergist disclosed by the invention has the beneficial effects that calcium cyanamide, lime and amino acid additive are adopted asmain raw materials, and calcium ammonium nitrate and modified carboxymethyl cellulose are added, so that the fertilizer-releasing capability and the fertilizer-effect lasting property can be changed,the loss of fertilizer nutrients can be reduced and the absorbing period of the rice root system to the fertilizer can be delayed; by matching and synergistic effects of potassium dihydrogen phosphate, zinc sulfate and calcium ammonium nitrate, the volatilization and loss of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer can be prevented, and the fertilizer can be immobilized, so that the fertilizer utilization rate is obviously increased; by addition of straws and waste paper boxes, the water retention rate can be effectively increased, and the nutrition loss can be prevented; an improver is added and simultaneously the rice planting synergist has the insect-expelling effect; the used raw materials are environment-friendly and can not cause pollution; the rice planting synergist is convenient in use and easy in preparation and is suitable for wide application.

Description

Technical field: [0001] The invention relates to the field of ecological organic fertilizers, in particular to a rice planting synergist. Background technique: [0002] my country is a country with a large agricultural development. The small area of ​​arable land and low grain output are the biggest problems facing my country's agricultural development. At present, the important means to increase grain output is the application of chemical fertilizers. my country is the largest producer and user of chemical fertilizers in the world. The annual amount of chemical fertilizer application accounts for 35% of the world's total, but the utilization rate of chemical fertilizers is less than 30%, which is far lower than that of developed countries. Due to the low utilization rate of chemical fertilizers, in order to pursue high crop yields, farmers use a large amount of chemical fertilizers, which not only increases the economic burden, but also pollutes the soil, causing the soil t...

AI Technical Summary

Problems solved by technology

However, because urine enzyme inhibitors and nitrification inhibitors are very easy to pollute water bodies, they are not suitable for long-term application, and the fertilizer effect extension period is short, and the synergistic effect on phosphorus and potassium fertilizers is not significant, so it is difficult to improve the comprehensive utilization rate of compound fertilizers.
