Cultivating method for grafting pears of other varieties onto pear trees

Abstract

The invention discloses a cultivating method for grafting pears of other varieties onto pear trees. The pear trees of different varieties are combined, grafted and matched according to different mature periods of different pear tree varieties, on the one hand, the natural fruit setting rate of the pear trees is increased and is increased by 30% to 40% compared with single variety planting, and compared with a previous cultivating mode, the labor and cost of artificial supplementary pollination are reduced, the yield of the pears is greatly increased, and the fruit quality is greatly improved; on the other hand, the mature periods of different varieties on the same tree are different, harvesting are staggered, the tree body supplies nutrition to the fruits in batches, the single fruit weight of the pear fruits is increased, the quality of the pear fruits is improved, and therefore the yield and benefits of unit area can be improved. Growth of the tree vigor can be adjusted, nutrient accumulation of fruiting branches is increased, and a foundation is laid for the high yield of the next year; through combining and grafting treatment, the mature periods of the pear trees of different varieties are correspondingly shortened, and economic value is improved.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation, in particular to a cultivation method for grafting pear trees with other varieties of pears. Background technique [0002] Pear is one of the main fruit trees in my country, and its cultivated area and output both rank first in the world. Among various fruit trees in my country, pear tree area and output are second only to apples and citrus, ranking third. Pear is a plant of the genus Pyrus in the family Rosaceae, which is rich in resources. There are 5 species mainly used for economic cultivation in China, namely Qiuzi pear, white pear, sand pear, foreign pear and Xinjiang pear. Among them, the white pear is suitable for cultivation in a freeze-dried climate, and the sand pear is suitable for cultivation in a warm and humid climate. They are the main species of pears cultivated in the Jianghuai River Basin. The climatic conditions required by foreign pears are similar to those of white pe...

Problems solved by technology

However, there are problems such as the proportion and configuration of the pollination tree in the configuration of the main plant species, and the problems of manual assisted pollination require a lot of labor and high cost.

[0004] In addition, the growth cycle of pears is relatively slow, generally four years. Compared with such a long growth cycle, the quality of the results of traditional cultivation methods is uneven, resulting in a greatly reduced economic value, and the same variety of pears is produced at the same maturity stage. The pear tree concentrates on the delivery of fruit nutrients. If the fruit load is a little too much and the management is a little improper, the growth of the tree will be affected immediately, and the tree vigor will decline seriously.
