Moss preventing and removing agent composition for rice and shrimp fields and preparation method thereof

Abstract

The invention provides a moss preventing and removing agent composition for a rice and shrimp field and a preparation method, and relates to the technical field of rice and shrimp field treatment. Themoss preventing and removing agent composition for rice comprises an active component A and an active component B, wherein the active component A is a sulfonylurea herbicide, and the active componentB is humic acid; wherein the weight ratio of the active component A to the active component B is 1: (99-499). The composition disclosed by the invention is safe and harmless to the growth of crayfish, can prevent moss in rice and crayfish fields from explosively growing, achieves the effect of fertilizing aquaculture water, promotes the growth of zooplankton and zooplankton in the water, and provides a good ecological environment for the crayfish.

Description

technical field [0001] The invention relates to the technical field of rice and shrimp field control, in particular to a moss control agent composition and a preparation method for rice and shrimp fields. Background technique [0002] Moss is a general term for filamentous green algae such as Spirogyra, Cladophora, and Hydronet algae. It is commonly found in still water bodies rich in organic matter. It will grow and reproduce in large quantities in sunny days with suitable temperatures in spring and early summer. In rice and shrimp fields, there are many rotting organic residues such as rice straw and aquatic plants, which can easily lead to moss outbreaks. The harm of moss in rice and shrimp fields is mainly manifested in the large growth and consumption of nutrients such as nitrogen, phosphorus, potassium and trace elements in the water body, which affects the growth of aquatic plants; floating on the water surface reduces the water temperature, soil temperature and disso...

AI Technical Summary

Problems solved by technology

The harm of moss in rice and shrimp fields is mainly manifested in the large growth and consumption of nutrients such as nitrogen, phosphorus, potassium and trace elements in the water body, which affects the growth of aquatic plants; floating on the water surface reduces the water temperature, soil temperature and dissolved oxygen concentration in the water body, affecting the growth of aquatic plants and crayfish ; Adhesion and entanglement on aquatic plants directly affect the growth of aquatic plants; crayfish often die because they are entangled and unable to escape; a large amount of moss rots and decomposes after aging and death, and the toxins produced by the decomposition further deteriorate the water quality and pond bottom quality, which is very easy to cause disease and death of crayfish

[0003] At present, there are already some control technologies for moss in rice fields, but there are still few control technologies that can be applied to rice and shrimp fields. Farmers often use manual salvage to remove moss, which is labor-intensive, low in efficiency, and quick to regenerate, making it impossible to effectively control; In addition, because we do not understand the harm of some moss control drugs to crayfish, we often use drugs to kill moss, which also causes a large number of deaths of crayfish and aquatic plants.
