摘要: 为研究施肥对毛竹根区土壤生物化学性质的影响, 在浙江省临安市牧家桥毛竹林中布置了施肥试验。研究结果表明:施有机肥显著增加了毛竹林间土壤和竹蔸根区土壤的细菌和真菌数量, 全有机肥(菜籽饼1 500 kghm-2)和1/2 有机肥(菜籽饼750 kghm-2 +硫酸铵168.8 kghm-2 +过磷酸钙97.5 kghm-2 +氯化钾16.2 kghm-2)处理林间土壤细菌数分别是对照区的2.20 倍和1.72 倍;竹蔸根区分别是对照区的1.91 倍和1.60 倍。全有机肥和1/2有机肥处理林间土壤真菌数分别是对照区的1.98 倍和1.62 倍;竹蔸根区分别是对照区的2.47 倍和1.89 倍。有机肥对毛竹林间和竹蔸根区土壤放线菌数量无明显影响。有机肥显著提高了毛竹林间和竹蔸根区土壤过氧化氢酶、脲酶、蛋白酶和磷酸酶的活性。全有机肥和1/2 有机肥林间土壤各类酶活性依次是对照区的1.24 倍、1.72 倍、1.82 倍、1.55 倍和1.07 倍、1.40 倍、1.53 倍、1.21 倍;竹蔸根区土壤各类酶活性分别是对照区的1.75 倍、2.10 倍、2.42 倍、1.61 倍和1.46 倍、1.67 倍、1.92 倍、1.07 倍。有机肥对毛竹土壤的蔗糖酶活性无明显影响。化肥可提高毛竹竹蔸根区脲酶和蛋白酶活性, 但化肥对林间土壤过氧化氢酶和脲酶活性无明显影响, 对林间土壤蛋白酶和磷酸酶活性影响也很小。化肥不能改变毛竹竹蔸根区土壤过氧化氢酶和磷酸酶的活性。表9 参11

Abstract: To understand the effects of fertilizing on biological properties of root region soil under Phyllostachys pubescens forest , a trial was done in bamboo forest in Linan City of Zhejiang Province .Application of oil cake caused a significant increase in the number of bacteria and fungi in both root region and non-root region soil whether total amount (1 500 kghm-2 oil cake)or half the amount of oil cake (750 kghm-2 oil cake plus equal amount of mineral N , P , K)being applied .The bacteria numbers of soil applies with total amount and half the amount of oil cake are 2.02 and 1.72 times as that of the chesk soil in non-root region , 1.91 and 1.60 times in root region respectively .As to fungi numbers , the corresponding times are 1.98 and 1.62 in non-root region , 2.47 and 1.89 in root region , respectively .The same effect does not occur in actinomyces .Application of oil cake activates enzyme activity such as hydrogen peroxidase , urease , protease and sucrase in both non-root region and root region soil under bamboo forest .The above enzyme activities of soil applied with total amount of oil cake are 1.24 , 1.72 , 1.82 , 1.55 times as that of check soil in non-root region and 1.75 , 2.10 , 2.42 , 1.61 times in root region , respectively .The above enzyme activities of soil applied with half the amount of oil cake are 1.07 , 1.40 , 1.53 , 1.21 times as that of check soil in non-root region and 1.46 , 1.67 , 1.92 , 1.07 times in root region , respectively .The similar case does not appear to sucrase .Application of pure mineral fertilizer has no affirmative effect on enzyme activity in both non-root region and root region soil except urease and protease in root region soil.
