苹果树秋施基肥,能大大增加树体内营养贮藏,既有利于提高越冬能力,又能稳定树势,充实枝芽,为提高果品产量和质量奠定基础。 一、适时早施,过去施基肥一般在果实采收后进行,而现在栽培的富士系、元帅系和乔纳金系品种,采收期多在10月中、下旬,施基肥多在11月进行,这时温度下降,有机质不易被微生物分解,加之断根愈合慢,分生根少,根系吸收能力弱,不利于树体恢复。合理的施肥时机是在大多数秋梢封顶后,一般是在9月
Apple tree autumn base fertilizer, can greatly increase the nutritional storage of trees in the body, both conducive to improving the ability of winter, but also to stabilize the tree vigor, enrich the buds, in order to improve fruit yield and quality laid the foundation. First, the timely implementation of the early, in the past generally applied after the basement fruit harvest, and now cultivated Fuji, Marshal Department and Jonathan gold varieties, harvested more in mid-October, late, more than the base fertilizer in November , When the temperature drops, the organic matter is not easy to be decomposed by microorganisms, combined with slow root healing, rooting less, the root absorption capacity is weak, is not conducive to tree recovery. Reasonable timing of fertilizer is in most of the autumn tip after the cap, usually in September
