叶面施肥对杉木苗期生长的影响研究

The Effect of Tow Foliar Fertilizers to Cunninghamia lanceolate Seedling

为了解叶面肥对杉木Cunninghamia lanceolate苗期生长质量的影响,对杉木苗分别喷施1.000 g·L^(-1)特多收和0.167 g·L^(-1)喷施宝叶面肥,结果表明:2种叶面肥处理3个月后杉木苗高度、干重量以及Ⅰ级苗比例与清水处理差异极显著(P<0.01),地径差异显著(P<0.05),特多收叶面肥处理较喷施宝叶面肥处理苗高、地径、干重量和Ⅰ级苗比例分别增加6.11%、5.17%、24.85%和7.02%,效果优于喷施宝。

To study the effects of foliar fertilizer on seedling growth of Cunninghamia lanceolate . The two foliar fertil- izers, Teduoshou 1. 000 g ·L^-1 and Penshibao 0. 125 g·L^-1 respectively were sprayed to Cunningharnia lanceolate seed- lings, The results showed that：after three months, Cunninghamia lanceolate seedling growth sprayed on foliar fertilizer were significantly higher than water treatment （P 〈0.01） in seedling height, ground diameter and seedlings graded class one. Ground diameter significant difference （P〈0.05） ,eduoshou treatment than Penshibao treatment in seedling height, ground diameter,dry weight and best seedlings ratio respectively increased by 6.11% .5.17% .24.85% .7.02%, the effect of Teduoshou treatment was more obvious than Penshibao treatment.
