摘要
为了改善果园土壤的理化性质及生物学特性,提高苹果的产量和品质,本试验设置了9个不同的施肥处理,研究蚯蚓粪有机肥与腐殖酸有机肥配施对苹果园土壤酶活性及果实品质的影响,从而得出不同生物有机肥之间的最佳配比。试验结果表明,田间施入生物肥均可以明显提高土壤蔗糖酶和脲酶的活性;不同生物有机肥配施能提高果园苹果的品质。蚯蚓粪2kg/株+腐殖酸1kg/株是最佳配肥方式。
In order to improve the physicochemical properties and biological characteristics of orchard soil,improve the yield and quality of apple,the test was carried out on nine different fertilization treatments of vermicompost and humic acid organic fertilizer treatment effects on apple orchard soil and fruit quality,so as to obtain the optimal proportion between different biological organic fertilizer.The test results show that the field application of bio fertilizer can improve the soil invertase and urease activity;different bio organic fertilizer could improve the internal and external quality of apple orchards.Earthworm manure 2 kg/tree plus humic acid1 kg/tree is the best fertilizer allocation method.
