Pollution-free special fertilizer for paddy field for inter-culturing shrimps

Abstract

The invention discloses a pollution-free special fertilizer for a paddy field for inter-culturing shrimps. The pollution-free special fertilizer for the paddy field for inter-culturing the shrimps is prepared from the following raw materials in proportions by weight: 30 to 50 parts of aquatic weed meal, 30 to 45 parts of animal excrement, 10 to 15 parts of bean pulp meal, 5 to 10 parts of fish meal, 20 to 40 parts of grain stillage powder, 5 to 10 parts of humic acid, 10 to 20 parts of fishpond sludge and 10 to 20 parts of wheat bran. The pollution-free special fertilizer for the paddy field for inter-culturing the shrimp is pollution-free and nuisanceless, contains many organic matters, is complete in nutrients, and can generate nicotine after becoming thoroughly decomposed, so that the fertilizer is alkalescent, and can be used for regulating acid soil; further, the adopted raw materials not only can be used for providing a nutriment for paddy, but also are foods for the shrimp, so that the paddy and the shrimp are jointly produced; the double bumper harvests of the paddy and the shrimp are realized; the economic benefit is greatly improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a pollution-free special fertilizer for paddy fields where shrimps are nested. Background technique [0002] China is one of the largest rice producers and consumers in the world. More than 60% of China's population is based on rice as a staple food. Therefore, rice production has always been an important issue related to national food security, and the benefit of single planting rice is low. Since the production environment of rice cannot be separated from water, shrimp farming in rice fields can greatly improve the benefit. The rice fertilizer contains a lot of harmful substances, which is not conducive to the growth of shrimp, and the non-use of fertilizer will reduce the rice yield. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing technical defects and provide a kind of non-pollutin...
