花生应用BN植物生长调节剂的效果

Effect of BN-regulators on Peanut Growth

以花豫 14为供试材料 ,研究BN植物生长调节剂对花生生长发育的效果。结果表明 :喷施BN使花生单株分枝数增加 0 .9～ 2 .0个 ,结果枝数增加 0 .5～ 1.6个 ,单株饱果数增加 2 .5～ 3 .0个 ,单株粒数增加 2 .4～ 4.5个 ,百粒重增加 0 .8～ 2 .6g ;喷施BN可以增大花生叶面积指数 ,提高光合效率 ,为花生高产奠定基础。喷施BN比对照增产 6.66%～ 12 .61% ,最适宜浓度为 6mg/kg。

The effect of BN-regulator on peanut variety-yuhua No. 14 growth and development was investigated. The result showed that the number of branch/plant increased 0.9～2.0, the number of effective branch/plant increased 0.5～1.6, the number of well filled fod per plant increased 2.5～3.0, the number of seed per plant increased 2.4～4.5, 100-seeds weight increased 0.8～2.6?g.The peanut treated with BN could increase LAI and photosynthetic rate, which provided high yield. The peanut yield can increase by 6.66%～12.61% under the condition of BN-regulators applied and the best concentration of BN-regulators applied in peanut was 6?mg/kg.
