(一)试种抗虫棉的情况分析。从去年试种的情况看,多数地方引种的抗虫棉表现较差。一是抗虫性差异大;二是纯度差,不稳定;三是丰产性差。普遍表现为叶小、株小、铃小、籽棉产量低。总之,去年抗虫棉大部分试种情况很不理想。据了解,有不少地方计划今年扩大种植面积。按去年抗虫棉种子量估计,若不加以控制,今年种植面积可能会超过100万亩。其原因,一是群众被棉铃虫“咬”怕了,想用一劳永逸的方法治住棉铃虫。二是有的单位在舆论导向上出现偏差,给群众以误导。三是有的地方过于轻信,在指导生产上带有一定的盲目性。若今年盲目扩大抗 (A) to test the situation of insect-resistant cotton. From last year’s trial of the situation, the majority of the introduction of insect-resistant cotton performance is poor. First, there are big differences in insect resistance; second, poor purity and instability; third, poor high yield. Generally manifested as small leaves, small plants, small bell, seed cotton yield is low. In short, most of the experimental cotton planting situation last year was not ideal. It is understood that many places plan to expand the planting area this year. According to last year’s estimated amount of insect-resistant cotton seed, if not controlled, this year’s planted area may exceed 100 million mu. The reason is that the masses are “bite” by the cotton bollworm, want to use the once and for all ways to control the bollworm. Second, some units appear to deviate from the direction of public opinion and mislead the masses. Third, some places are too gullible to guide the production with a certain degree of blindness. If this blind expansion of resistance
