盐液浸根沾浆造林是滦平坑木林总场科技人员在试验成功的一项技术,取得了显著经济效益。该项技术操作方便、投资少,效益高,易推广。其操作方法是:以50公斤水加0.25公斤食盐,配制成0.5%盐液水,再加少许黄土,搅拌成稀粥状,将苗根浸入其中,约30分钟左右即可栽植。该项技术造林效果好。该场巴克什营林场1981～1984年的油松造林试验区比对照区提高成活率15—24%;据总场调查盐液浸根沾浆造林成活率高于对照区的11～39%。滦平坑木林总场自1981～1990年,共推广油松、刺槐等树种盐液浸根沾浆造林9.7万亩。按最低提高造林成活率计算,即多成活造林面积9700亩,每亩造林直接成本25元,共为国家节省造林经费24.25万元。而以50公斤水加0.25公斤食盐,配制
Saltwater dip rooting and soaking afforestation is a technique that has been successfully tested by Luanping pit mounds and achieved significant economic benefits. The technology is easy to operate, less investment, high efficiency, easy to promote. The method of operation is as follows: add 0.25 kg of salt to 50 kg of water, prepare 0.5% salt water, add a little loess, stir into gruel and immerse the seedling root for about 30 minutes. The technology afforestation effect is good. According to the total field survey, the survival rate of saltwater immersion with root dip was higher than that of the control area by 11-39%. Luanping pit total volume of forest since 1981 to 1990, a total of promoting pine, acacia and other tree species soaked in salt immersion rooting of 97,000 mu of afforestation. According to the minimum afforestation survival rate, that is, the survival of more than 9700 acres of afforestation, afforestation direct cost of 25 yuan per mu, a total of 242,500 yuan for the state save afforestation funding. And 50 kilograms of water plus 0.25 kilograms of salt, preparation
