Environment-friendly fertilizer dedicated to rice and duck co-cultivation

Abstract

The invention discloses an environment-friendly fertilizer dedicated to rice and duck co-cultivation. The environment-friendly fertilizer is prepared from the following raw materials in parts by weight: 10 to 30 parts of urea, 15 to 30 parts of ammonium dihydrogen phosphate, 5 to 20 parts of potash magnesium sulphate fertilizer, 0.5 to 0.15 part of zinc sulfate, 20 to 40 parts of seabird faeces, 5 to 15 parts of fermented rice straw, 20 to 45 parts of corn cake, 10 to 30 parts of bone dreg, 20 to 40 parts of humic acid, 15 to 30 parts of modified grass carbon, 5 to 15 parts of corn straw, 5 to 15 parts of dolomite powder, 1 to 5 parts of bentonite, 5 to 15 parts of kaolin, 0.1 to 0.35 part of sodium silicate, 5 to 10 parts of magnesium sulfate, 0.05 to 0.09 part of botanical pesticide and 0.05 to 0.15 part of compound bacteria. The environment-friendly fertilizer disclosed by the invention is good in sustained-release effect and balanced in nutrition, is capable of slowly releasing nutrient substances according to growth characteristics of rice, is suitable for a duck and rice co-cultivation environment, is environment-friendly and can be used for killing insects and controlling weeds.

Description

technical field [0001] The invention relates to the technical field of rice fertilizer, in particular to an environment-friendly special fertilizer for rice-duck breeding. 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 impr...

Problems solved by technology

[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
