Effect on different tillage methods to young walnut plantations

对核桃幼林采用3种不同的耕作方式进行试验观测,结果表明,耕作施肥并间作大豆的核桃幼林Ⅱ的土壤物理性状优于耕作不施肥间作玉米的核桃幼林Ⅲ和弃耕的核桃幼林Ⅰ;核桃幼林Ⅱ中的幼树单株平均地径、树高、冠幅、枝条数、花芽数、结果数均优于核桃幼林Ⅲ,显著大于核桃林Ⅰ。

The walnut young was tested using 3 kinds of different tillage methods. The results show that tillage fertilization and intercropping of soybean in samples of walnut grove Ⅱ, its soil physical properties be better than farming with non-fertilization intercropping maize in samples of walnut grove Ⅲ and not to cultivate the land of samples of walnut grove Ⅰ;small trees in a samples of walnut grove Ⅱ, its average ground diameter, tree height, crown breadth, the number of branches, the fl ower bud number, result quantity are better than samples of walnut grove Ⅲ,signifi cantly greater than samples of walnut grove Ⅰ。
