5种栽培模式对油茶土壤微生物及酶活性的影响

以毛豆、花生、绿豆、四季豆套种及覆草为试验栽培模式，探讨不同栽培模式对油茶、土壤微生物及土壤酶活性的影响。结果表明：5种栽培模式对油茶新梢生长、单株产果量及出油率有显著影响，但对鲜出籽率影响不明显；对土壤微生物数量和酶活性均存在显著差异，根际土壤微生物数量和酶活性比非根际土壤高；综合分析得出在油茶林下套种毛豆和绿豆2种模式最好。细菌与真菌、各种土壤酶活性以及出油率均有显著或极显著相关关系，说明土壤细菌可作用为判断土壤肥力状况的生物学指标。

Effects of Five Kinds of Cultivation on the Soil Microorganisms and Enzyme Activities of Camellia oleifera Forestry

In this paper, five cultivation modes of experiment which are interplant of Soybean, peanut, mung bean, kidney bean and the covering grass, were explored to discuss the effects of different cultivation on Camellia oleifera, soil microorganisms and enzyme activities. The results indicated that new tip length, the yield of single tree and oil yield of the five cultivation modes had significantly differences, except for fresh seeds yield. The quantities of microbes and the activities of enzymes in the rhizosphere soil were higher than in the non rhizosphere soil. Based on the above analysis, interplant of soy beans and mung beans were the most beneficial modes to C. Oleifera. The bacteria was significant correlation with various kinds of soil enzyme and oil yield, which illustrated that the quantity of bacteria could be used as biological indicator to detect soil fertility, and providing the basis to judge C. Oleifera oil production.
