Description

technical field

[0001] The invention belongs to the technical field of plant protection and fertilizers, and in particular relates to the use of fulvic acid and fulvic acid salts in the control of weeds in transplanted paddy fields and the increase of rice production. Background technique

[0002] Rice is the largest food crop in my country. There are many types of weeds in paddy fields, and the types of weeds are different in different regions. There are more than 200 species of weeds in rice areas across the country, of which there are about 40 common and serious weeds. kind. At present, the control of weeds in transplanted rice fields is mainly based on chemical herbicides. For example, benzazine pretilachlor, pyrazole pretilachlor, pretilachlor, etc. can be used to control barnyardgrass, echinacea and other grasses. Undergraduate, sedge and broad-leaved weeds; stem and leaf herbicides can be quinclorac and its intermixtures. Although herbicides are highly efficient and ...
