在春季,山葡萄萌芽、展叶、抽梢、开花所需的大部分营养,是树体在上一年积累的。树体营养充足,萌芽率高、展叶、抽梢快,开花座果率也高。为满足树体生长发育的需要给树体补充营养,除在植株萌芽后及浆果生长期追施化肥外,还要进行秋施肥。秋施肥以农家肥为主,具有营养全面,供肥时期长,增加土壤有机质含量,改善土壤结构,促进根系生长的作用,所以也称秋施基肥。春施有机肥,待土壤微生物分解,根系不能马上吸收利用,而且伤根系和不利保墒。秋施肥地温高,肥料分解快,切断根系能很快恢复,根系可吸收施入的肥料,增加 In spring, mountain grapes sprout, show leaf, shoot tip, most of the nutrients required for flowering, is the tree accumulated in the previous year. Tree adequate nutrition, high germination rate, Zhanye, fast shoots, flowering rate is also high. To meet the needs of tree growth and development to the tree nutritional supplements, in addition to the topdressing of the plants after the bud and berry growth fertilizer, but also for autumn fertilization. Autumn fertilization dominated by farmyard manure, with a comprehensive nutrition, a long period for the fertilizer, increase soil organic matter content, improve soil structure and promote root growth, so it is also known as autumn basal fertilizer. Spring applied organic fertilizer, soil microbial decomposition, the root can not be absorbed immediately, but also hurt the root system and adverse moisture. Autumn fertilizer high temperature, fertilizer decomposition fast, cut off the root can be quickly restored, the roots can absorb the applied fertilizer, increase
