The invention relates to applications of a fulvic acid composition in paddy field weed prevention and control and paddy rice yield increasing. The fulvic acid composition comprises potassium fulvic acid, an amino acid, film coated urea, and nicotine at a weight ratio of 6-8:1-3:0.5-2:0.05-0.1. The fulvic acid composition possesses nutrient adjusting effect, is capable of preventing and controllinggramineous weeds and broadleaf weeds, and increasing paddy rice yield at the same time.
Description
technical field [0001] The invention belongs to the field of plant protection and fertilizer technology, and in particular relates to the use of a fulvic acid composition in the control of weeds in paddy fields and the increase of rice production. Background technique [0002] Weeds in paddy fields are an important part of paddy field ecosystems. They compete with rice for various resources such as light, water, and soil nutrients. Because of their many types, fast reproduction, vigorous growth, and difficulty in controlling and eradicating them, weeds can easily cause crop damage. Yield reduction or even grain failure is an important factor affecting rice yield and quality, resulting in 12.3%-16.5% crop yield reduction every year. Effective field control and management of weeds in paddy fields is crucial to the growth of paddy crops. [0003] At present, weed control in paddy fields is mainly based on chemical herbicides. For example, benzazine pretilachlor, pyrazole pretil...
