解放钟枇杷[Eriobotrya japonica(Thumb.)Lindl.]配方施肥技术研究

A Study on the Technique of the Formula Fertilization Method on the Jie fang-zhong Loquat[Eriobotrya japonica(Thumb.)Lindl.]

以常太库区红壤土山地枇杷园为对象,研究了不同配方施肥对解放钟枇杷生长和产量的影响。试验结果显示:增施枇杷专用的配方肥料能够明显促进枇杷增产,改善枇杷的果实品质,可在枇杷生产上推广应用。与CK相比,枇杷冠幅增加58.95%,干周增加20.5%,单位面积产量提高42.18%,枇杷果实平均单果重增加3.2g,可溶性固形物提高1.2%、可溶性总糖提高1.3%,枇杷果实的可滴定酸降低0.15%。

The formula fertilization method was used on the Jie fang-zhong loquat at the red earth mountain area in Changtai Puting. The results showed the formula fertilization method of applying more special fertilizer on loquat can apparently promote the yield and improve the fruit quality of loquat. The method can be applied and popularized in production. Compared with application of CK, the experimental results showed that, the formula fertilization of special fertilizer on loquat was able to increase the crown diameter by 58.95%, and the perimeter of trunk rised by 20.5%, the yield per unit enhanced by 42.18%, and average weight of individual fruit enhanced by 3.2g, and soluble solids content increased by 1.2%, soluble total sugar content also increased by 1.3% and the titratable acid content of fruit decreased by 0.15%.
