棉花蕾铃的大量脱落,直接影响着产量的迅速提高,本市郊区1957年棉花蕾铃平均脱落率为62％,58年由于农业生产大跃进,加肥加水。加强了田间管理,蕾铃脱落率虽较57年有所降低,但平均脱落率仍达58.1％,为了保征明年棉花跃进指标的胜利完成,大力开展棉花保蕾保铃的斗争,将脱落率大大降低,是一项增产的关键性措施。根据田间检查,一般说来棉花蕾铃脱落率水地高于旱地,丰产田高于一般地,管理粗放田块高于管理细致田块。至于分析蕾铃脱落的原
A large number of cotton buds off, a direct impact on the rapid increase in output, the suburbs of cotton in 1957, the average shedding rate of 62% of the buds, 58 years due to the great leap forward in agricultural production, plus fertilizer and water. Strengthened field management, although the drop-out rate of buds was lower than that of 57 years, the average drop-off rate still reached 58.1%. In order to ensure the victory of next year’s cotton leap index completion, vigorously carry out the fight against cotton bolls, Greatly reduced, is a key measure to increase production. According to field inspection, in general, the cotton bud loss rate is higher than dryland, yield field higher than normal, the management of extensive fields higher than the management of plots. As for the analysis of the original fall of the lampblack
