提高麦田化学除草效果,关键是要掌握以下的技术措施:1.土壤湿度:在麦田湿度较大时,既有利于草籽的萌发,又有利于药剂被杂草吸收传导,因此除草效果就好。反之,若土壤干燥,影响杂草发芽和杂草对药剂的吸收,除草效果就差。因此,应掌握在土壤湿度大的 The key is to improve the wheat field chemical weeding, the key is to master the following technical measures: 1. Soil moisture: Wheat field humidity is large, both conducive to the germination of grass seeds, but also conducive to chemical absorption and conduction of weeds, so the weeding effect is good . On the contrary, if the soil is dry, affect the weeds germination and weeds on the absorption of drugs, weeding effect is poor. Therefore, we should master the humidity in the soil
