Red pear dwarfing interstock close-planting cultivation technique

Abstract

The invention discloses a red pear dwarfing interstock close-planting cultivation technique which includes the key steps: selecting early-matured red pears and red pears No. 2; selecting dwarfing interstocks No. 2; selecting birchleaf pears or sand pears as grafting stocks; performing close-planting cultivation; performing modified leader training in a shaping method; promoting branching; inhibiting top shoot growth; totally cultivating three layers of lateral branches; cultivating fruit-bearing branch groups on the lateral branches. The height of a tree is within 2m after the tree is formed, interline space larger than 1m serves as a ventilating duct, and 8-10 lateral branches are cultivated on the whole tree. The technique further includes the steps of nutrient and water management, fruit thinning, rain shelter cultivation, bagging, disease and pest prevention and the like, and accordingly solves the problems of late fruiting, poor yielding ability, difficulty in coloring, weak resistance and the like of the red pears cultivated in the south.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a red pear dwarf intermediate stock close planting cultivation technique. Background technique [0002] Red pear is an emerging characteristic pear variety, which is very popular in the market, but it is mainly cultivated in the northern region, and it can only be cultivated in high-altitude areas such as Yunnan and Guizhou in the southern region, but it has not been successfully cultivated in low-altitude and rainy regions in the south. case. The cultivation of red pears in low-altitude and rainy areas in the south mainly has the following problems: late fruiting, poor yield, difficult coloring, and weak resistance. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a dwarfing intermediate stock close-planting cultivation technique for red pears, which can solve the problems of...
