编辑同志:去年我国不少棉区前期低温,棉苗生育偏晚,中期多雨,蕾铃脱落严重,晚桃比例过高,以致种子成熟度差,质量普遍下降。据调查,有些地区秋桃占一半以上,嫩子率高达20—30%,子指降低到8克上下,发芽率只有50—60%。因此,建议这些地区今年棉花播种前除了要准备充足的种子外,还要比往年更加认真地进行选种晒种,以提高种子的生活力、发芽势和发芽率,要把这项工作当做棉花播种保全苗、壮苗,为夺取棉花 Editorial Comrades: In the past year, many cotton areas in our country were in low temperature in the early period, and cotton seedlings were late in birth, rainy in the middle period, with serious falling buds and excessive proportion of late peaches, resulting in poor seed maturity and generally declining quality. According to the survey, in some areas more than half of autumn peach, tender child rate as high as 20-30%, sub-fingers down to 8 grams up and down, the germination rate is only 50-60%. Therefore, it is recommended that cotton plants in these areas should not only prepare sufficient seeds before sowing this year, but also carry out more thorough seed-dressing than usual in order to improve the viability, germination potential and germination rate of the seeds. This work should be regarded as cotton Seeding security seedlings, strong seedlings, to seize cotton
