一、控制徒长 1.B_9B_9能显著地抑制细胞有丝分裂和伸长,抑制茎枝生长。喷施后茎枝生长减缓,变得短而粗壮,机械组织发达,植株矮壮株型密集,且能使叶片加厚,提高叶绿索含量,加快光合速率,一般增产15.4%,喷施的浓度应为1000ppm,喷施时期为始花后40～50天叶面喷施。中低产田不宜施用。 2.多效唑(pp_(333)) 是一种新型植物生长延缓剂,可有效地控制茎枝生长,促进地下生长,增强抗倒伏能力和光合能力,增加结果数
First, control leggy 1.B_9B_9 can significantly inhibit cell mitosis and elongation, inhibit stem growth. After spraying, the stems grew slowly, became short and thick, the mechanical tissue developed, the plants were strong and strong, and the leaves could be thickened, the content of chlorophyll increased, the photosynthetic rate was accelerated, and the yield increased by 15.4% Concentration should be 1000ppm, spraying period of 40 to 50 days after the beginning of flower foliar spraying. Low-yield field should not be applied. Paclobutrazol (pp_ (333)) is a new plant growth retardant, which can effectively control the growth of stems, promote underground growth, enhance lodging resistance and photosynthetic capacity, increase the number of results
