Problems solved by technology

Manual salvage is time-consuming and laborious, with low efficiency, high cost and little effect
Biological control is still in the experimental stage, and it will take at least 3 to 5 years to be effective, and it is still difficult to determine whether biological control will have an impact on the existing ecological balance. There are still many problems to be studied and resolved in order to promote it.
Chemical control is currently the most used method, but the existing chemical control is poor in effect and takes a long time to kill; second, it has complex components and high cost; decline

Abstract

Disclosed is a hyacinth scavenger which is a chemical scavenger for exterminating hyacinths and has no pollution to the environment. The invention has the mixed inorganic cupric salt and zinc salt for preparing aqueous solution to be sprayed on leaf surfaces and petioles of hyacinths for extermination. The scavenger has good effects and can rapidly exterminate the hyacinths without pollution to water and existential threats to aquatic animals, and has advantages of simple operation, low price and easy promotion and application.

Description

technical field [0001] The invention relates to a chemical herbicide, in particular to a chemical scavenger used for clearing water hyacinth and causing no pollution to the environment. Background technique [0002] Water hyacinth is a perennial aquatic plant introduced from abroad in the early years in our country. It has almost no natural enemies in our country, and because of its strong reproductive ability, it can reproduce several times to dozens of times its own in a very short period of time. Individuals reproduce and grow in large numbers in many waters in my country, and have formed a single dominant community. It seriously destroys the ecological balance of the original rivers and lakes, affects the reproduction and growth of fish, and blocks the river course, affecting water traffic. In the vast waters of southern my country, water hyacinth has been flooded. [0003] In order to control the catastrophic reproduction of water hyacinth, the methods commonly used at...
