Cultivation and management method of packhams through plain net rack top grafting and variety changing

Abstract

The invention relates to a cultivation and management method of packhams through plain net rack top grafting and variety changing. The method is characterized by comprising the following steps of S1, selection of stocks; S2, selection of scions; S3, treatment of the scions; S4, treatment of the stocks; S5, grafting; S6, racking and corner opening; S7, cultivation of bearing branches in the current year; S8, pruning management; S9, bearing management; S10, management in the third year. Compared with a traditional mode of not building a net rack, the cultivation and management method of the packhams through plain net rack top grafting and variety changing has the advantages that flower buds are easier to form, a large number of secondary branches are formed by adopting new shoots after corner opening, and the building mode is more conductive to management and picking, so that the management and picking process is safer and more efficient compared with a traditional mode; a net rack built for top grafting trees is more conductive to ventilation and light transmitting, so that the fruit quality is significantly improved; branches on the back of the packhams cultivated on a flat shed rack are few, shaping and pruning mainly comprise bud picking and branch thinning, the pruning workload is greatly reduced, the packhams bears fruits early, the yield is high, and the quality is good.

Description

technical field [0001] The invention relates to a cultivation and management method of 'Packham' pears, specifically, a method for cultivating and managing 'Packham' pears by means of using a flat net frame to connect and replace, and belongs to the cultivation and management of pear trees method technology field. Background technique [0002] Western pear is one of the two major cultivated pears in the world, and the fruit is famous all over the world for its delicious taste and high quality. Yantai is the area where pears were introduced the earliest and have the largest cultivation area in China. Due to the unique climate characteristics and environmental conditions in Yantai, it has become a suitable area for the cultivation of Western pears in my country, and has been identified as an advantageous area for the cultivation of Western pears by the Ministry of Agriculture. In recent years, Western pears have developed rapidly. Many excellent varieties of Western pears su...

Problems solved by technology

The method adopts flat grid cultivation technology to realize rapid forming, reasonable distribution of branches, moderate density, good ventilation and light transmission between tree rows, early fruiting and early high yield, and solves the disorder of tree shape in the production of pears in the prior art. Long cultivation time, late fruiting, late high yield, low yield, and difficult daily management caused by the handover between rows of tree crowns
