以往经验证明,棉花缺肥将造成蕾铃大量脱落;水大肥足,棉株徒长,也引起脱落.阿拉玉斯坦大队,历来棉花蕾铃大量脱落,形成“中空”现象;而今年800亩棉花,产量突破百斤皮棉,看来与合理施肥,有效地保住了蕾铃,有一定的关系.今年棉田普范增施基肥,一般在3,000斤以上,质量也好;不少棉田播前和播时还施用了过磷酸钙,现蕾期又追施硝酸铵20—30斤,样板田还在开花期追施了氮肥.从样板田的总施肥量看,基本上可以满足百斤皮棉生长所需的营养,从而保住了蕾铃,减少脱落,基本上防止了“中空”现象.根据今年试验和调查,
Past experience shows that lack of cotton cotton will cause a large number of buds fall off; water big fat feet, cotton plant leggy, also caused off.Alajustein brigade, cotton buds have long been a large number of fall off, forming a “hollow” phenomenon; this year 800 acres of cotton , The output exceeded the pearl lint, it seems reasonable with fertilizers, effectively preserving the buds, there is a certain relationship between this year’s cotton Pudan increase base fertilizer, generally more than 3,000 pounds, the quality is good; a lot of cotton before sowing and broadcasting time But also the application of superphosphate, budding and chasing ammonium nitrate 20-30 pounds, sample field is still topdressing flowering nitrogen fertilizer from the total amount of fertilizer field view, basically to meet the needs of lint lint growth Nutrition, so as to keep the buds, reduce shedding, basically to prevent the phenomenon of “hollow.” According to this year’s tests and surveys,
