In recent years, due to successive years of crop use of chemical herbicides, chemical fertilizer dosage, improper application methods and methods, reduced use of organic fertilizer, planthopper pollination caused by excessive accumulation of pesticide residues in rice, lack of some The toxic effects of chemical substances, virus disease caused by stiff seedlings, affecting the level of rice production increased.
