林木种子静电处理苗木生长效应分析

AN ANALYSIS ON GROWTH EFFECT OF NURSERY STOCK FOR TREE SEEDS TREATED WITH STATIC ELECTRICITY

本文以最优静电处理参数下刺槐、紫穗槐、沙棘播种苗为研究对象。采用Logistic方程和t-检验方法对3种苗木年高生长节律和其它生长性状进行了分析和评价,结果表明,静电处理林木种子苗木生长效应是提高了出苗速率;改变了年生长节律—速生期提前和变短、瞬时生长速率增大、抗逆性能提高;改善了苗木生长性状、增加了生物量。为提高单位面积苗木产量和质量,探索了一条切实可行的新途径。

The object of study in this paper is the sown seedlings of Robinia pseudoacacia, Amorpha fruticosa and Hippophac rhamnoides, which are in the best static treatment parameter. By using Logistic equation and t-test, the growth law of annual hight and the other growth charaiters of three kinds of nursery stocks were analysed and appraised. The results showed that the growth effect of the nursery stock for static treatment of wood seeds has raised the rate of emergence, and changed the anunual growth law; advancing and shortening speedy growing time, incrensign instantaneous growth velocity, raising counter-resistance, and also improved growth characters of the nursery stock as well as increased the organism measare. The author explores a feasible new channel for raising per unit yield and the quality of nursery stocks.
