香椿是我国的特有经济树种,由于香椿成枝力弱,树冠小,遮荫面积小,适宜与粮食作物问作,因此是林粮立体种植的较佳树种。为此,我们于1994～1996年,在黄河故道地区开展了椿粮立体种植的技术研究。通过试验,获得了椿粮双丰收,每亩平均产香椿芽40.13kg,粮食341.5kg,与纯粮田相比,平均增收234元。现将栽培模式和栽培技术总结如下。 Toon is an endemic economic tree species in our country. Due to weak branches, small canopy and small shading area, Toon is a better tree species for planting three-dimensional forest crops. To this end, we conducted a technical study on the stereoscopic planting of prawn grains in the old course of the Yellow River from 1994 to 1996. Through the experiment, we got the double harvest of piles and seeds. The average yield of Toona sinensis per mu was 40.13kg, and the grain was 341.5kg. Compared with the pure grain field, the average yield increased by 234 yuan. Now cultivation patterns and cultivation techniques are summarized below.
