Compound fertilizer suitable for shrimp farming rice fields and preparation method thereof

Abstract

The invention discloses a compound fertilizer suitable for shrimp farming rice fields and a preparation method thereof. The compound fertilizer comprises the following components in parts by weight: 15-18 parts of potassium chloride, 8-10 parts of urea, 2-4 parts of calcium superphosphate, 2-4 parts of plant ash, 3-5 parts of cow dung, 2-4 parts of soybean meal and 8-10 parts of selenium-enriched yeast, wherein the above components are mixed to prepare a mixture A. The compound fertilizer also comprises the following components in parts by weight: 8-10 parts of wheat bran, 1-3 parts of cattle bone meal, 3-5 parts of fish meal, 3-5 parts of peanut cake, 2-4 parts of bean cake, 1 part of clamshell powder and 1 part of rice bran, wherein the above components are mixed to prepare a mixture B. The mixture A and the mixture B are stirred and mixed, 6-8 parts of compound enzyme, 3-5 parts of vitamin D and 3-5 parts of vitamin E are added, and full stirring and mixing are conducted to obtain a mixture C. The compound fertilizer is green, healthy and reasonable in proportion, can provide nutrients required by growth of rice, and can also promote growth and development of crayfish, so that the economic benefit of a crayfish breeding rice field is improved; and the whole preparation process is simple in process, short in consumed time and low in required manpower and material resource cost.

Description

technical field [0001] The invention relates to the field of compound fertilizer preparation, in particular to a compound fertilizer suitable for shrimp paddy fields and a preparation method thereof. Background technique [0002] The "rice + shrimp" model refers to a high-efficiency ecological species that uses paddy fields as the basis, without reducing food production, to cultivate crayfish in paddy fields, and to play the symbiotic and mutually beneficial role of rice and lobsters, so as to obtain a double harvest of rice and lobsters. raising mode. Within a unit area, the economic value brought by crayfish is three times that of rice. Simply put, "shrimp farming in rice fields" can bring farmers four times the original income. Therefore, more and more farmers have begun to learn and adopt " The novel model of raising shrimps in paddy fields. [0003] In recent years, the application of the rice and shrimp farming model has been increasing year by year across the countr...

Problems solved by technology

[0005] In the special mode of "shrimp farming in rice fields", special attention should be paid to the type and dosage of chemical fertilizers. Once the chemical fertilizers are improperly selected or the dosage is too much, it will have an adverse effect on the growth of crayfish
