Special organic fertilizer for rice grain setting stage and preparation method thereof

Abstract

The invention relates to the field of organic fertilizer, in particular to a special organic fertilizer for the rice grain setting stage and a preparation method thereof. The special organic fertilizer is prepared from, by weight, 45-55 parts of straw, 8-10 parts of bean pulp, 6-8 parts of cottonseed meal, 3-5 parts of mushroom residues, 4-6 parts of lignin residues, 1-2 parts of bran, 8-10 parts of rice chaff, 3-5 parts of fish meal, 2-4 parts of licorice powder, 1-3 parts of mineral additives, 0.5-1 part of microelements and 5-10 parts of amino acid. The organic fertilizer contains a large amount of organic matter, the capability of the organic fertilizer for improving, activating, loosening and changing the granular structure and physical and chemical properties of soil can be exerted, and the water and fertilizer reservation capability of soil can be improved; various mineral microelements needed in the grain setting stage can be provided, the special organic fertilizer has the fast-acting property of chemical fertilizer, and various physiological diseases caused by microelement deficiency in the grain setting stage can be prevented and treated, so that other diseases are reduced, rice grows robustly in the whole grain setting stage, and a good foundation is laid for increase of the final yield per mu.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a special organic fertilizer used for rice seed-bearing period and a preparation method thereof. Background technique [0002] The growth process of rice is roughly divided into four stages: seedling stage, tillering stage, long ear stage, and fruit-bearing stage. Normal growth and development requires more nutrient elements, especially nitrogen, phosphorus and potassium. It cannot meet the needs of rice growth and development. At present, chemical fertilizers are often applied in several times to ensure sufficient nutrient supply for rice. However, with the increase of nitrogen, phosphorus and potassium application, a large number of nutrients are relatively enriched, not only As a result, the utilization rate has decreased, resources have been wasted, and the environment has been polluted. With the excess of a large number of nutrients, the content of trace elements in the so...

Problems solved by technology

[0002] The growth process of rice is roughly divided into four stages: seedling stage, tillering stage, long panicle stage, and fruiting stage. Normal growth and development require more nutrients, especially nitrogen, phosphorus, and potassium. Relying solely on soil The supply of rice cannot meet the needs of rice growth and development. At present, chemical fertilizers are often applied in multiple times to ensure sufficient nutrient supply for rice. Cause the utilization rate to drop, and waste resources, pollute the environment, along with the excess of macronutrient elements, the content of trace elements in the soil can no longer meet the demand, and the deficiency of trace elements in rice is also increasing day by day. Not the same, if one-time fertilization is used, it is easier to cause the loss of nutrients
