有机肥与生物菌肥配施对旱区果园土壤酶活性和果树光合能力的影响
Effects of combined application of organic fertilizer and bio-fertilizer on soil enzyme activities and photosynthetic capacity of fruit trees in dryland orchards
摘要
Abstract
To clarify the effects of combined application of organic fertilizer and bio-fertilizer on soil properties and leaf photosynthetic capacity of fruit trees in apple orchards in arid areas under mulching with horticultural ground fabric,this study used apple variety Yanfu 8 as the test material,and set up no fertilization control(CK),vermicompost treatment(T1),bio-fertilizer treatment(T2)and vermicompost and bio-fertilizer(3∶1)combined application treatment(T3)to analyze the effects of different fertilizer treatments on soil physical and chemical properties and enzyme activities in apple orchards and photosynthetic parameters of fruit trees.The results showed that compared with CK,the water contents of surface soil(0-20.0 cm)in T1,T2 and T3 treatments at harvest stage increased by 40.48%,18.33%and 51.67%,respectively,and the pH values decreased by 6.86%,5.20%and 13.24%,respectively.At 60-180 days after anthesis,except that the alkaline phosphatase activity in surface soil under T3 treatment was lower than that under CK at 60 days after anthesis,the catalase activity,peroxidase activity,sucrase activity,alkaline phosphatase ac-tivity and urease activity in surface soil under T3 treatment were significantly higher than those under CK.The effect of T3 treatment on the increase of soil enzyme activity was higher than that of T1 and T2 treatments.Compared with CK,the in-tercellular CO2 concentration in fruit tree leaves at harvest stage under T1,T2 and T3 treatments decreased by 13.30%,7.62%and 6.20%respectively,the net photosynthetic rate increased by 67.36%,47.97%and 81.74%respectively,and the stomatal conductance increased by 37.50%,53.12%and 84.38%respectively.In summary,the combined application of vermicompost and bio-fertilizer at 3∶1 mass ratio can improve soil ecological functions and promote fruit tree growth through the improvement of soil physical and chemical properties,enhancement of soil enzyme activities,and strengthening of plant photosynthetic capacity.关键词
