绿竹浸根施肥对造林影响的研究初报

A Preliminary Study of Effect of Root-soaking Fertilizing on Dendrocalamopsis oldhami Forest Establishment

初步研究了常见肥种浸根施肥对绿竹造林的影响。结果显示,浆内加入磷酸二氢钾、尿素、过磷酸钙对造林第1年的成活率、萌发率及新竹的数量、大小都具有一定的提高和促进作用。对新竹的株数的影响,不同肥种间无显著差异,但磷酸二氢钾、尿素与对照有显著差异;对新竹直径的和的影响,各肥种与对照之间都有显著差异,但不同肥种间无显著差异。

We studied preliminarily the effect of root-socking fertilizer application on the establishment of Dendrocalamopsis oldhami forests. The results indicated that KH2PO4, Co （NH4）2, Ca（H2PO4）2.HEO＋CaSO4 could improve and facilitate to some extent the survival rate and sprouting rate of the D.Oldhami forests in the first year as well as their number and size. The 3 fertilizers had no significant difference in terms of the effect on the number of bamboo culms, but KH2PO4 and Co（NH4）2 had a significant difference from the control group in the regard. There were obvious effect of using KH2PO4,Co（NH4）2, Ca（H2PO4）E.H2O＋CaSO4 on the diameter of new-sprouted culms, but the difference among three fertilizers was not obvious.
