桃树匍匐栽培是寒冷地区(一般是指年均温<6.5℃,冬季最低温<-28℃以上地区)特有的一种栽培方式,在我省海拔1600～1750米的范围内栽植较好。匍匐栽培防冻的主要原理是;由于越冬埋土防寒可使土内的温度和湿度有明显的提高,从而减小了外界温湿骤变对树体引起的冻害,其早结果的原理是由于树体倾斜,顶端优势受到抑制,所以枝条中部和基部的背上芽容易萌发成短枝,利于花芽分化,促使早花、早果,同时还有密植性好,低冠、光照条件好等特点: 一、园地选择 桃树耐干忌涝,喜沙性土,根系好氧性强,园地应选择土质疏松,排水良好、富含有机质的壤土。土壤粘重时,应在栽植前客沙换土,应避勉在低洼、积水处建
Peach prostrate cultivation is a cold area (generally refers to the annual average temperature <6.5 ℃, the lowest temperature in winter <-28 ℃ above) a unique cultivation methods, in our province at an altitude of 1600 to 1750 meters planted better. The main principle of frost-cultivating antifreeze is that as the cold winter buried soil can make the temperature and humidity in the soil significantly increased, thereby reducing the external temperature and humidity on the trees caused by sudden frost damage, the principle of its early results is due to the tree Body tilt, the top edge is inhibited, so the branches on the back of the shoot bud easily sprouted into short branches, which will help flower bud differentiation, to promote early flowering, early fruit, as well as close planting, low crown, light conditions are good and so on: First, the choice of garden Peach drought-tolerant flood, Xisha soil, root aerobic, garden should choose loose soil, well-drained, organic-rich loam. Viscous soil, soil should be replaced before planting passenger shelter, should be avoided in the low-lying, stagnant water to build
