摘要: 为了探讨施用不同肥料对板栗Castanea mollissima林土壤性质的影响,在浙江省临安市布置了肥料试验。研究结果表明:无论施用有机肥还是施用化肥处理,与不施肥比较,土壤碱解氮、有效磷及速效钾的质量分数都有显著提高,并随着化肥施肥量的增加,土壤有效养分明显上升。处理1(复合肥2 250 kghm- 2)土壤碱解氮、有效磷和速效钾质量分数分别是不施肥处理(处理5)的1.18, 1.58和2.71倍;处理2(2倍处理1)则分别是对照的2.48,2.88和2.98倍,而全有机肥处理4(菜籽饼5 400 kghm- 2)则分别是对照的1.84, 2.10和1.58倍。施用有机肥土壤磷酸酶和蔗糖酶活性明显高于(P 0.05)施化肥土壤。有机肥也明显增加了土壤水溶性有机碳和微生物量碳的质量分数,处理3(1/2处理1加1/2处理4)水溶性有机碳和微生物量碳的质量分数是对照的1.15和1.15倍,处理4则是对照的1.57和1.43倍。试验表明,施肥能明显提高土壤有效养分,而有机肥较无机肥更有利于土壤生物学性质的改善。表4参26

Abstract: Chinese chestnut(Castanea mollissima)is an important plantation in Zhejiang Province for its high cash profit. Fertilization has become a usefulway to improve itsyield. The objective of this paperis to find outthe effects of different types and rates of fertilizers on soil available nutrients and biochemical properties by one-year field fertilizer trial. It was found that soil available N, P and K positively response to the increase of mineral fertilizer, and their concentrations in the soil of treatment1(compound fertilizer: 2 250 kghm- 2) and treatment 2(two times the amount of treatment 1)are respectively 1.18, 1.58, 2.71 times and 2.48, 2.88, 2.98 times more than in the control(no fertilizer), and their concentrations in treatment4(oil cake: 5 400 kghm- 2)were 1.84, 2.10, 1.58 times as many as in the control. Organic fertilizer had a positive influence on activities of soil phosphatase and sucrase, which were significantly more active in the soil treated with oil cake(P 0.05) than those treated with mineral fertilizer. Soil water-soluble organic carbon(WSOC) and microbial biomass carbon(MBC) for treatment 3(0.5 times the amount of treatment 1 plus 0.5 times the amount of treatment 4) were respectively 1.15 and 1.15 times more than the control, and those for treatment 4 were 1.57 and 1.43 times more than the control. Itwas concluded that the practice of fertilization enriched the soil available nutrients, especially organic fertilizer, which had better effects on soil biochemical and biological properties than mineral fertilizer.[Ch, 4 tab. 26 ref.]
