Rice-duck co-cultivating organic-inorganic compound fertilizer

Abstract

The invention discloses a rice-duck co-cultivating organic-inorganic compound fertilizer. The rice-duck co-cultivating organic-inorganic comopund fertilizer is prepared from the following raw materials in parts by weight: 15 to 35 parts of urea, 10 to 30 parts of monoammonium phosphate, 10 to 20 parts of potassium humate, 0.5 to 2.5 parts of EDTA manganese chelate, 15 to 35 parts of seabird droppings, 20 to 50 parts of fermental chicken droppings, 10 to 30 parts of rape seed cake, 5 to 10 parts of bone dreg, 10 to 20 parts of wormcast, 5 to 10 parts of modified grass carbon, 10 to 18 parts of plant ash, 2 to 10 parts of bentonite, 2 to 8 parts of attapulgite, 3 to 12 parts of calcined kaolin, 0.2 to 0.8 part of ferrous sulfate, 2 to 4 parts of talcum powder, 0.1 to 0.8 part of plant source farm chemical and 0.01 to 0.08 part of compound bacteria. The fertilizer provided by the invention is environment-friendly and nutritionally balanced, is capable of killing pests and controlling grass, and slowly releasing nutrient substances therein according to the growth characteristics of rice and is suitable for a rice-duck co-cultivation environment.

Description

technical field [0001] The invention relates to the technical field of rice fertilizer, in particular to an organic-inorganic compound fertilizer for rice-duck co-cultivation. Background technique [0002] Rice is the main food crop in our country, and it is widely planted in South China, Central China, North China, Southwest China, Northeast China and other places in our country. The rice planting industry supports our agricultural planting industry and provides rice grain to the people of the whole country and even the people of the world. However, the existing Rice planting has the defect that the yield and quality cannot be taken into account, and it cannot meet the needs of the growing agriculture. The rice and duck co-production solves the water environment needs of ducks and fish and the fertilizer needs of rice. It is a kind of development potential. However, the technology of rice-duck co-cropping is still not very perfect; at present, there is a serious problem of ...

[0002] Rice is the main food crop in our country, and it is widely planted in South China, Central China, North China, Southwest China, Northeast China and other places in our country. The rice planting industry supports our agricultural planting industry and provides rice grain to the people of the whole country and even the people of the world. However, the existing Rice planting has the defect that the yield and quality cannot be taken into account, and it cannot meet the needs of the growing agriculture. The rice and duck co-production solves the water environment needs of ducks and fish and the fertilizer needs of rice. It is a kind of development potential. However, the technology of rice-duck co-cropping is still not very perfect; at the present stage, there is a serious problem of improper use of chemical pesticides in rice-duck co-cropping. Excessive use of pesticides has caused serious damage to human health and the environment. Harmful, and the quality of rice is not good, the organicity is poor, and the yield is low
