生物有机肥对陇东旱塬苹果生长的影响

Effect of Bio-organic Fertilizer on Apple Growth in Arid Plateau of Longdong Area

为了探讨生物有机肥对苹果的增产效应,在矮密栽培苹果园和乔化栽培苹果园中,采用3因子、4处理、3重复田间试验,研究了生物有机肥及其它有机物料在苹果生产中的效应。结果表明,各种有机物料对苹果生产均有促进作用,其中生物有机肥效果最好;施用生物有机肥的矮密栽培的‘中秋王’苹果比对照显著增产12.8%,经济效益提高16.7%;施用生物有机肥的乔化‘红富士’苹果比对照显著增产15.1%,经济效益提高26.5%。

In order to explore the effect of bio-organic fertilizer on increasing yield of apple,the effects of bio-organic fertilizer and other organic materials on apple production were studied by using three factors,four treatments and three repeated field experiments in dwarf and dense apple orchards and arbor cultivated apple orchards in dry plateau of eastern Gansu province.The results showed that all kinds of organic materials could promote apple production,but bio-organic fertilizer had the best effect and the application of bio-organic fertilizer significantly increased the yield of‘Zhongqiuwang’apple by 12.8%and the economic benefit by 16.7%.The application of bio-organic fertilizer significantly increased the yield of Qiaohua‘Red Fuji’apple by 15.1%and 26.5%compared with the control.
