Culture and breeding methods for apple tree of new species

Abstract

The invention relates to a culture method for an apple tree of new species. The culture method comprises the following steps: A1, enabling the Qinguan apple tree to be subjected to branch grafting or bud grafting on the Qiaohuaxinhongxing apple tree; A2, enabling the cultured Qiaohuaxinhongxing apple tree obtained in the step A1 to be subjected to branch grafting or bud grafting on the Qiaohuachangfu No.2 tree; A3, enabling the cultured Qiaohuachangfu No.2 tree obtained in the step A2 to be subjected to branch grafting or bud grafting on the M26 dwarfing interstock; and A4, enabling the first cultured M26 dwarfing interstock obtained in the step A3 to be subjected to branch grafting or bud grafting on the red fuji spur apple tree, so as to obtain the apple tree of the new species. The invention also relates to a breeding method of the apple tree of the new species. The breeding method comprises the following steps: grafting the M26 dwarfing interstock on selected tree seedlings, and grafting the branches or buds of the apple tree of the new species on the M26 dwarfing interstock. The fruit tree obtained by the culture and breeding methods for the apple tree of the new species has the advantages that the quality is good, the fruiting period and the mature period are advanced, and the fruits are larger, uniform in color, palatable in sweetness and crispness, large in yield and high in economic value.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and in particular relates to a cultivation and breeding method of a new variety of apple tree. Background technique [0002] my country is the world's number one producer and consumer of apples, with a large total area of ​​apple cultivation and a high yield of apples. However, compared with developed countries, the yield per unit area of ​​apples in my country is lower, the overall quality of the fruit is poorer, and there are problems such as low economic benefits of orchards. At present, most orchards in my country adopt the dense planting mode of arbor anvils for apple planting management, but the orchards under this mode are relatively airtight, which easily leads to problems such as uneven light exposure of fruit trees, fruit tree fruiting time and fruit ripening time are late. In addition, the cultivation technology of apples in various parts of my country is relatively backward. The qu...

Problems solved by technology

However, compared with developed countries, the yield per unit area of ​​apples in my country is relatively low, the overall quality of the fruit is poor, and there are problems such as low economic benefits of orchards.

At present, most orchards in my country adopt the close-planting cultivation mode of arbor anvils for apple planting management, but the orchards under this mode are relatively airtight, which easily leads to problems such as uneven light exposure of fruit trees, fruit tree fruiting time and fruit ripening time.

In addition, the cultivation technology of apples in various parts of my country is relatively backward, the quality of the cultivated apple seedlings is not good, the fruit produced by the fruit trees is small, the color of the fruit is uneven, the taste is not good, and the quality of the fruit is poor, which seriously affects the economic benefits of apple orchards
