多效抗旱驱鼠剂室内促长效果研究

An Indoor Test the Effects of RPA on Plant Growth

室内用多效抗旱驱鼠剂对小麦、黄豆、油松、侧柏种子进行浸种、拌种处理。结果表明 ,30 0 x的林用型和 2 0 0 x的农用型 RPA对侧柏种子浸种效果最好 ,30 x的林用型和 80 x的农用型 RPA拌种效果最好 ,经检验分析 ,差异显著 ;5 0 0 x的林用型和 6 0 0 x的农用型 RPA对油松促长效果更为明显 ,发芽率比对照提高 2 5 .2 %～ 2 7.0 % ,平均高生长增加 2 .1～ 2 .8cm ,拌种型的两种药剂 6个浓度对油松的发芽及生长影响比较明显 ,30 x的林用型和 4 0 x的农用型可以使油松发芽率提高 2 7.7%～ 2 9.8% ,苗高增长 0 .6～ 1.3cm;对黄豆的发芽率提高 12 .0 %～ 17.0 %、13.8%～ 2 3.2 % ;侧根数量增加 0 .2～ 2 .6、0 .3～ 1.6条 ,平均苗高及生物量也有不同程度的提高 ;浸种型的 RPA使小麦发芽率提高 13.3%～ 2 3.3% ,苗高增长 5 .1～ 7.5 cm,根长增加 0 .6～ 1.8cm;拌种型 RPA发芽率提高 9.3%～ 2 2 .6 % ,苗高增长 4 .7～ 6 .6 cm,根长增加 0 .4～ 1.6 cm。

Effect of RPA on growth,of wheat, soybean, Chinese pine and arborvitae Has been tested.The results were obtained in the seed germination and seedlings growth to use two type of RPA in 6 densities. Presoaking pine seed in 500 times of RPA of forest type, the germination rate increased 25.2%～27.0%, height of seedlings increased 2.1～2.8 cm compared with CK. Dressing pine seeds with 30 timesof RPA of forest type, the germination rate increased 27.7%～29.8%, and the height of seedlings increased 0.6～1.3 cm. Dressing soybean seeds with 40 times of RPA of agricultural type, the germination rate increased 13.8%～23.2%, the number of lateral roots increased 0.3～1.6 times more than CK. Presoaking wheat seeds in RPA, the germination rate increased 13.3%～23.3%, height of seedlings growth increased 5.1～ 7.5 cm , length of root increased 0.6～1.8 cm. Dressing wheat seed with RPA the germination rate increased 9.3%～22.6%, height of growth increased 4.7～6.6 cm, length of root increased 0.4～1.6 cm.
