When will chemical weeding be carried out in rice fields? Please introduce that weeds in paddy field have a great influence on rice growth. Weeds compete with rice for fertilizer, water and glory, which directly affect rice growth and, in serious cases, reduce rice yield. therefore, chemical weeding in paddy field is very important to promote the normal growth of rice. In June, a large area of rice in Dali City has entered the tillering stage. according to the investigation of rice seedling situation, rice leaves withered in some rice fields, which is caused by the blind application of chemical herbicides by farmers. The techniques of chemical weeding in paddy field are introduced as follows: 1. Weeding techniques at budding stage: in 7-10 days after rice transplanting, during the period of weed germination, 50% herbicide 200-250ml is applied to 30 kg soil per mu, or 50 grams of barnyard weed powder plus 10 grams of Xindeli is mixed per mu, and the effect of water conservation is better for 7-10 days. 2. Weeding techniques at seedling stage: in the 1-3 leaf stage of weeds, 100 grams of 50% promethazine per mu, 30 kg of soil dressing, and water retention for 7-10 days. This can ensure the weeding effect, ensure the normal growth of rice, make the seedlings take root early, turn green early, tiller early, mature normally, and finally do not affect the yield of rice. It is reported that the main weeds in rice fields can be divided into three categories: Gramineae weeds, broadleaf weeds and Cyperaceae weeds.
