新疆几种主要特色果树施肥现状调查研究

以新疆几种主要特色果树(苹果、香梨、灰枣、核桃)为研究对象,分别在阿克苏市红旗坡农场、柯克亚林管站、实验林场和核桃林场,以农户为单元进行果树施肥调查.结果表明:四种果树在基肥使用上均以羊粪为主,有时辅以少量油渣;追肥则以二胺、尿素和氨基酸铵为主;每公顷施肥量呈现苹果>香梨>灰枣>核桃的递减趋势,盛果期果树施肥养分N:P2O5:K2O依次为1:0.92:0.08、1:0.94:0.02、1:0.72:0.03和1:1.35:0.06:施肥次数和时期因当地气候和果园灌水时间而产生差异,施肥次数依次为3、4、5、3次.

The Investigation Research of Fertilization about Several Main Characteristic Fruit Trees in Xinjiang

Take several main characteristic fruit trees in Xinjiang(Malus, Pyrus, Jujuba, Regia)as the objects of study, take peasant household as the unit to investigate fruit trees fertilization in Akesu city.The results showed that the basal fertilizer of four kinds of fruit trees is sheep excrement primarily, sometimes supplemented by a small amount of diesel oil.While additional fertilizer is diamidogen, urea and amino acid ammonium mainly;Application rate of each hectare presents Malus > Pyrus > Jujuba > Regia and shows decreasing tendency, N:P2O5:K2O in fertilizer nutrient for the fruitful trees is 1:0.92:0.08, 1:0.94:0.02, 1:0.72:0.03 and 1:1.35:0.06 in turn;The frequency of application and the time of application have the difference because of the local climate and the orchard irrigation time, the frequency of application followed by 3,4,5,3.
