Technical field
The invention belongs to field of fruit tree cultivation, the method for particularly frame pears shaping in a kind of theatre.
Background technology
The pergola system technique functions of modern pears comes from Japan, pear tree pergola system can reduce the loss that typhoon causes, be convenient to orchard daily management, yield per unit area is high, the operatic circle quality better, the traditional pear tree planting type of China is standing tree formula, nineteen ninety-five Daliang City Introduced from Japan pears pergola system technology the earliest.According to incompletely statistics, there is frame theatre about 100,000 hm in current China
2, be mainly distributed in East Coastal or the coastal waters provinces and cities such as Shandong, Liaoning, Hebei, Zhejiang, Jiangsu, Shanghai, Fujian, Jiangxi, Hubei, Henan, Anhui, Sichuan etc. are economized also a small amount of plantation.
Current pear tree frame shape mainly comprises: horizontal type frame, arch or ridge-shaped frame pattern etc., wherein horizontal type frame is common a kind of pear tree pergola system pattern, also be the frame pattern that Japan generally adopts, China's horizontal rack theatre is built material and is mainly adopted concrete column, most by setting transformation greatly from garden building method, and garden is built in treelet field planting.
Horizontal rack pruning is tree-like mainly contain horizontal shape, infundibulate, compromise shape, cup-like shape [Xu Yiliu. Japanese pear tree frame pruning technique [J], fruit tree 2011(1): 56-57]:
Horizontal shape: fixed doing selects and remain angle, good 4 vegetative shoot of growth potential then as major branch, and when next year, the winter cut flat tie on frame face, stay 45cm cutting back, within 3rd year, from the vegetative shoot that every article of major branch is sprouted, select l article as major branch elongated shoot, select 2 else as side shoot, occupy about elongated shoot respectively, and at a right angle with major branch elongated shoot, draw respectively when the winter cuts and be bonded on frame face;
Infundibulate: all good vegetative shoot 3 of fixed dry select and remain then angle, growth potential when next year, the winter cut in cutting back, to select and remain from the branch that every bar vegetative shoot is sprouted 2 major branches, within 3rd year, continue major branch of selecting and remain, after planting, the 4th year every strain pear tree Dual culture goes out 18 articles of major branches, and major branch level is drawn and tied up on frame frame face;
Compromise shape: this is tree-like establishes 3 major branches, and extend respectively to positive north, the southeast, southwestward, between major branch, angle is 120 °, each major branch configures 2 ~ 3 side shoots, each side shoot is joined several middle or small shape fruit-bearing shoot clusters, side shoot with forward life;
Cup-like shape: fixed dry select 3 ~ 4 angles then, nutrition skill that growth potential is good cultivates as major branch, the side skill of rib shape arrangement is turned out in major branch both sides, and 7 ~ 8 years every bar major branches of raw tree turn out side shoot 3 ~ 4;
China's Introduced from Japan frame shape is mainly tree-like is main for tearing inner feelings shape open tree-like, from introducing this tree-like condition of production at present, this tree-like pruning is complicated, canopy face often occurs the chaotic problem of branch structure, on the one hand, because pear tree pergola system technology is also in the Demonstration And Extension stage in China, another side, peasant also the technology such as integrated use pruning, water, fertilizer can not regulate and control tree vigo(u)r.Thus, cause amount of growth between this tree-like different major branch different; Major branch, side shoot, secondary side shoot " identity " indefinite; Major branch, side shoot direction of extension are indefinite; Permanent tree and a tip branch juxtaposition of cutting down trees; On canopy face, developmental branch bar forms " mountain " font; And major branch and secondary scaffold branch tip growth potential weak, therefore this tree-like performance tree is chaotic mutually, and do not reach pergola system effect, cause tree vigo(u)r weak, the underproduction, fruit quality declines.
