摘要
通过番石榴大田小区试验,研究在配方肥+有机肥的基础上,增施氨基酸叶面微肥、钙镁中量元素肥(土施)和锌硼钼微量元素叶面肥对番石榴产量和品质的影响。结果表明:与习惯施肥对照相比,增施氨基酸叶面微肥、钙镁中量元素肥+锌硼钼微量元素叶面肥,番石榴每株产量分别增加20.67%和21.63%,差异均达显著水平(p<0.05),对番石榴果实的单果重、VC、可溶性糖和固形物含量的提高均有一定的促进作用。
Guava(Psidium guajava L.)applied with formulated fertilizer and organic fertilizer was dressed with additional fertilizers,amino acid microelement fertilizer,calcium-magnesium fertilizer(soil application)and zinc-boron-molybdenum foliar fertilizer in a field experiment to study the effects of the additional fertilizers on its yield and quality.There were 5 treatments:45%NPK fertilizer(CK);40%NPK formulated fertilizer+organic fertilizer(FOF);formulated fertilizer+organic fertilizer+amino acid microelement fertilizer(AAF);formulated fertilizer+organic fertilizer+calcium-magnesium fertilizer(CMF);formulated fertilizer+organic fertilizer+calcium-magnesium fertilizer+zinc-boronmolybdenum foliar fertilizer(CZF).The results showed that the guava plants under the AAF and CZF treatments increased their yield per plant by 20.67%and 21.63%,respectively,against the CK(p<0.05).The fruit weight per fruit,and the contents of vitamin C,soluble sugar and solids in guava fruit were also obviously increased under the treatments of AAF,CMF and CZF.
