摘要
以‘阿森泰克’苹果为试材,在61团9连苹果园进行不同施肥试验,设置在常规施肥基础上增施硫酸钾肥(T1)、在常规施肥基础上增施黄腐酸钾肥(T2)、常规施肥(CK)3个处理,研究了不同施肥处理对果园土壤理化性质、容重、孔隙度和养分含量以及苹果果实品质的影响,以期为改进伊犁地区土壤施肥方式和苹果优质栽培生产提供参考依据。结果表明:增施硫酸钾肥和黄腐酸钾肥调节了土壤pH,降低了水溶性总盐含量,增加了不同土层土壤有机质和养分含量,还降低了土壤容重,改善了土壤通透性。与CK相比,T1和T2处理显著增加了苹果可溶性糖和维生素C含量,增幅分别为11.82%、19.74%和14.85%、29.71%,降低了可滴定酸含量,降幅为18.18%和30.30%,改善了果实品质。整体看,增施黄腐酸钾肥的效果要优于增施硫酸钾肥。
Taking apple‘Asentek’as the test material,different fertilization experiments were conducted in the apple orchard of the 9 th Company of the 61 st Regiment.Three treatments were set up,increasing potassium sulfate fertilizer on the basis of conventional fertilization(T1),increasing potassium fulvate fertilizer on the basis of conventional fertilization(T2),and local fertilization method(CK).The changes in soil physical and chemical properties,bulk density,porosity,and nutrient content in the orchard,as well as the quality of apple fruits were studied,in order to provide reference for improving the soil fertilization method and apple quality cultivation and production in Yili area.The results showed that the addition of potassium sulfate and potassium fulvate fertilizers regulated soil pH,reduced the contents of water soluble total salts,increased soil organic matter and nutrient content in different soil layers,and also reduced soil bulk density and improved soil permeability.Compared with CK,T1 and T2 treatments significantly increased the contents of soluble sugar and vitamin C,with increases of 11.82%,19.74%and 14.85%,29.71%respectively,and reduced the content of titratable acid,with decreases of 18.18%and 30.30%,improving the quality of fruits.Overall,the effect of increasing potassium fulvate fertilizer was better than that of increasing potassium sulfate fertilizer.
