摘要
依据60块标准地420株样木,对太行山刺槐单株及林分的叶量变化规律进行了研究;建立了叶量回归估测方程;计算出太行山刺槐叶资源量为105776t,可利用叶饲料资源为52888t.通过对18头猪重复3次饲养试验,证明刺槐叶具有较高的营养价值和饲料效应。
Based on 420 samples from 60 plots, the leaf biomass of individual trees and stands of Black Locust (Robina pseudoacacia L.) forests were studied. The leaf resources is 105,776t, and 79,332t can be used for forage. The regression equation for leaf biomass has been established with accuracy over 90%. Based on feeding experiments with 18 pigs, the nutritive value of leaf forage were tested.
