【摘要】：毛竹是我國最為重要的經(jīng)濟竹種,對區(qū)域農(nóng)村社會經(jīng)濟發(fā)展和生態(tài)環(huán)境保護具有重要作用。為了解沼液施肥對雷竹新竹生長和土壤化學性質(zhì)的影響,測定了全年一次性沼液施肥處理的試驗毛竹林新竹質(zhì)量、葉片SPAD值、鞭根根系活力和土壤基本化學性狀指標。結(jié)果表明:沼液施肥毛竹林立竹密度變化影響不明顯,而新竹數(shù)量、胸徑、全高、枝下高、胸高壁厚及葉片SPAD值、鞭根根系活力與對照(CK)相比均顯著提高;處理Ⅱ和處理Ⅲ,新竹胸徑、全高、葉片SPAD值和鞭根根系活力差異不顯著,且顯著高于處理Ⅰ。沼液施肥顯著提高了毛竹林土壤pH值、有機質(zhì)質(zhì)量分數(shù)和土壤主要養(yǎng)分質(zhì)量分數(shù);處理Ⅱ和處理Ⅲ,毛竹林土壤的pH值和全磷、速效磷、全鉀、速效鉀質(zhì)量分數(shù)差異不顯著,均顯著高于處理Ⅰ。因此,沼液施肥可明顯提高毛竹林新竹質(zhì)量,改善毛竹林土壤基本化學性狀,試驗毛竹林適宜的沼液施肥量為45 t·hm~(-2)。
[Abstract]:Phyllostachys pubescens is the most important economic bamboo species in China, which plays an important role in regional rural social and economic development and ecological environment protection. The quality of new bamboo, SPAD value of leaves, root vigor of rhizome and basic chemical characters of soil were measured in the experiment. The results showed that the change of bamboo density in bamboo stand with biogas liquid fertilization was not obvious. However, the number, diameter at breast height, total height, height under branch, wall thickness of chest height, SPAD value of leaf, root activity of root of whip root were all significantly higher than those of control group, but there was no significant difference between treatment 鈪，
