缩节安是一种新型的棉花激素,它是一种高效内吸性生长调节剂,能抑制细胞和节间伸长,增加叶绿素合成。对于控制旺长,塑造株型,矮化株体,代替整枝,减少蕾铃脱落,促进早熟,增加铃重和提高品质具有明显的增产作用。 1984年我团开始大面积应用缩节安,地膜棉施用面积4228亩,单产皮棉209.4斤,其中250斤以上条田1351亩。有37.2亩单产达到304斤。1985年在总结经验的基础上,棉花施缩节安面积达17600亩,其中地膜棉11800亩,单产186斤,常规棉5800亩,单产120斤,地膜棉250斤以上条田1721亩,其中小面积高产田85.6亩,单产再次突破300斤,分别达到302.9斤和311.7斤。全团一级花总产304万
Diananan is a new type of cotton hormone, which is a highly efficient systemic growth regulator that inhibits cell and internodal elongation and increases chlorophyll synthesis. For the control of a long, shape plant type, dwarfed body, instead of pruning, reduce the buds off, promote early maturity, increase boll weight and improve quality has obvious yield. In 1984, we started to use large-area shrinkage shrinkage. The area covered with cotton membrane was 4228 mu and 209.4 kg of lint yield per mu, of which 1351 mu was above 250 kg. 37.2 acres yield reached 304 pounds. On the basis of summing up the experience in 1985, the area for cotton shrubs and contractors reached 17,600 mu, of which 118,100 mu was cotton mulch, yielding 186 kg, 5800 mu for conventional cotton, 120 kg for cotton yield, 1,721 mu for strip mulching more than 250 pounds, 85.6 acres of high-yield area, yield again exceeded 300 pounds, respectively, to 302.9 kg and 311.7 kg. The whole group a total output of 3040000 flowers
