Summary of the invention

Goal of the invention: the object of this invention is to provide a kind of based on the novel frame of the tree-like pear tree of happy shape and utilize its make pear tree effectively increase production, fruit matter improve Japanese sand pear cultivation method.

Technical scheme: in order to realize foregoing invention object, the novel frame of one of the present invention comprises that some spacing are that the column of 2.2 ~ 2.4m is arranged in length and breadth, four limits of column are provided with the side column that flare 15 is spent, four angles of column are also provided with four corner posts that inclination angle is 25 degree, described column vertical and horizontal draw steel wire apart from ground 1.7 ~ 1.8m, and be fixed on described side column, side column and corner post use wire loop around fixing in periphery; Every adjacent four root posts are also provided with a pillar along diagonal crossed crunode, and every pillar draws fixation with steel wire in high peripherad four root posts of 1.5 ~ 1.6m.

The difference of frame of the present invention and existing frame is, the present invention on column steel wire not at rock line in length and breadth, but diagonal wiring, be further, the direction of diagonal wiring is oblique lower, utilize frame plantation sand pear of the present invention, also it doesn't matter in the suitable minimizing of distance between rows and hills in time, reasonably draw branch by coordinating, make the oblique lower growth of major branch, also meet the growth speciality of pear tree reality, and major branch is the inclined-plane under oblique, be conducive to illumination, the convenient producer prunes, the management such as fruit thinning, utilize frame of the present invention, the angle that the steel wire of Diagonal line has a down dip is greatly about 15 ° ~ 30 ° left and right, can reach requirement completely by an early stage technology of drawing.

For the method for utilizing the Japanese sand pear of above-mentioned pergola system, First Year Dong Jian selected center is dry, at 30-40cm place cutting back; Second Year draws branch autumn, draw branch autumn, to major branch and the suitable cutting back of side shoot, do three happy tree-like cultivations, utilize the auxiliary branch that draws of the dry polarity of 0.1g/L forchlorfenuron solution-treated debranching simultaneously, to trunk being tied on column intersection steel wire in the 3rd year, further fixedly make it along steel wire to the oblique lower growth of column.

Method of the present invention must coordinate novel frame to use, and is specially adapted to wish to make to customize the compacter producer of pear tree, thereby improves per mu yield and economic benefit.Because pear tree lignification is more serious, therefore draw especially in the fall branch and utilize forchlorfenuron processing.Fact proved, the major branch that forchlorfenuron was processed can more easily be walked along steel wire under artificial treatment, and can upwards not grow.Further, described forchlorfenuron is sprayed onto major branch and needs bend, after generation tiller, removes in time.

Beneficial effect: the three happy tree-like cooperation frames plantations that pear tree of the present invention cultivation adopts, frame improves on the basis based on prior art, due to frame bracing wire oblique under, therefore the requirement of drawing branch is seemed to higher.The feature such as high based on pear tree degree of lignification, trunk is strong, complements each other by physical treatment and chemical treatment, makes the oblique lower growth of major branch, has increased the actual sensitive surface of pear tree.

Embodiment
