最近,全国每年防除棉花病、虫、草害的面积达到1000—1200万公顷。1980—1982年平均每年收获皮棉1000万吨。在夺取棉花高产中,植物保护工作具有很大作用。众所周知,在轮作棉花中,采取特别措施可以使棉花每年减少15—20%的可能损失。已经知道,在中亚和南部哈萨克植棉共和国,综合防治使皮棉产量平均提高4—5公担/公顷。而每消耗一卢布可以增加6—10卢布的收入。在病虫害综合防治中,化学防治还有很
Recently, the annual area of cotton diseases, pests and weeds in the country has reached 10-12 million hectares. From 1980 to 1982, an average of 10 million tons of lint was harvested each year. In seizing cotton high yield, plant protection work has a great role. It is well-known that in cotton rotation, special measures can be taken to reduce cotton losses by 15-20% annually. It is already known that in the cotton-growing Republic of Kazakhstan in Central and South Kazakhstan, the integrated control increases the lint yield by an average of 4-5 m³ / ha. And every spent one ruble can increase 6-10 rubles of income. In the integrated pest management, chemical control is still very much
