Special fertilizer for water plants for shrimp and crab culture pond

Abstract

The invention discloses special fertilizer for water plants for a shrimp and crab culture pond. The fertilizer is prepared from raw materials in parts by weight as follows: 5-15 parts of monoammonium phosphate, 10-30 parts of urea, 5-20 parts of poly potassium phosphate, 5-15 parts of bentonite, 2-10 parts of pottery clay, 2-8 parts of zeolite powder, 2-10 parts of borax, 5-12 parts of weathered coal, 1-4 parts of nano calcium carbonate, 10-20 parts of molasses powder, 2-12 parts of fish meal, 5-15 parts of fermented cassava, 2-10 parts of chicken manure, 5-15 parts of honey, 0.5-1.5 parts of EDTA (ethylene diamine tetraacetic acid) chelated manganese, 0.5-1.5 parts of diaminoferric xanthohumate and 1-6 parts of an outer-layer coating agent. The fertilizer is environment-friendly, contains very rich nutritional substances, has the good slow-release effect and can meet requirements of the water plants in the whole growth period through one-time fertilizer application.

Description

technical field [0001] The invention relates to the technical field of aquatic fertilizers, in particular to a special fertilizer for weeds in shrimp and crab breeding ponds. Background technique [0002] In hot summer, when the water temperature is too high, freshwater shrimp and crabs can hide in aquatic plants to enjoy the coolness from the sun. In winter, aquatic plants also have a good thermal insulation effect. The most important thing is that aquatic plants can purify water quality, improve the environment, and provide a high-quality ecological environment for the growth of freshwater shrimp and crabs. Aquatic plants carry out photosynthesis, which can increase dissolved oxygen in water, which is the primary productivity in water environment. At present, the added feed for aquatic plants cannot guarantee the health and stability of the ecological community of aquatic plants throughout the breeding cycle, resulting in vigorous growth of aquatic plants in stages, and ...

Problems solved by technology

At present, the added feed for aquatic plants cannot guarantee the health and stability of the ecological community of aquatic plants throughout the breeding cycle, resulting in vigorous growth of aquatic plants in stages, and at the same time, large areas of aquatic plants wither in stages, affecting the normal growth and development of shrimp and crabs
