传统的果树基肥施用,都是安排在秋季,但笔者认为这种一刀切的做法并不可取,应根据不同果树的发育过程和需肥特点施基肥。基肥秋施,对于晚熟的果树是合适的,但对于早熟的果树就不合适。比如说大樱桃,果实生长发育期非常短,从开花到采果都集中在春季的50天左右,在这样短的时间内,果树长叶、开花、结果依次进行,而果树枝叶的营养转换还没有完成,不可能给树提供大量新的营养,只有依靠树体去年积累的营养完成这一切活动,因此,在前一年尽量提高树体的营养积累水平,是樱桃树的主要施肥目的。而要达到这一目的,就要在前 The traditional fruit tree basal application, are arranged in the autumn, but I think this one-size-fits-all approach is not desirable, should be based on the development of different fruit trees and fertilizer characteristics of the base fertilizer. Base fertilizer autumn facilities, suitable for late-maturing fruit trees, but not suitable for early-maturing fruit trees. For example, cherry, fruit growth and development period is very short, from the flowering to picking fruit are concentrated in the spring of about 50 days, in such a short period of time, the fruit of the long leaves, flowering, the results in turn, Without it, it is impossible to provide the tree with a lot of new nutrients. Only by relying on the nutrients accumulated by the tree last year can do all this. Therefore, maximizing the level of nutrient accumulation in the tree the previous year is the main purpose of cherry tree fertilization. To achieve this goal, we must first
