Description
Technical Field
The invention belongs to the technical field of fruit tree planting, and particularly relates to a method for improving fruit set percentage by controlling top end advantages through trunk-shaped pear tree high grafting.
Background
The pear is a plant of the genus Pyri of the family Rosaceae, and has perennial deciduous fruit trees, arbors, oval leaves, whitish flowers, juicy fruits, crisp meat, delicious taste, rich nutrition, and contains protein, fat, sugar, crude fiber, minerals such as calcium, phosphorus, iron, and various vitamins, etc., and has the effects of lowering blood pressure, nourishing yin and clearing heat. The life of the pear tree is long and can reach more than 100 years.
Pear is a cross-pollinating plant, and pollen of other varieties is needed for pollination and fructification. The growth vigor of different varieties has obvious difference, pollinated varieties are fixedly planted in rows or between rows, inconvenience is brought to field farming management and fruit harvesting, and meanwhile, the garden appearance is not neat; the top advantages of the pear trees are strong, the trunk-shaped pear trees are easy to form strong upper parts and weak lower parts, the growth potential of lower branch groups is weakened, cross pollination is caused, the pollination and fertilization are poor, the fruit setting rate is unstable, the fruit is few, the fruit is small, the fruit shape is not correct, and the fruit quality is reduced.

(4) in the next year, the variety B and the variety C at the top of the pear tree bloom, the variety B and the variety C are pollinated with each other, and meanwhile, the pollen of the variety B and the pollen of the variety C are pollinated with the variety A respectively.
According to the method, a main cultivar A is selected, and a weak pollination variety is grafted and grown on the upper end of the main cultivar A, so that the top advantages of pear trees are effectively controlled, the pollination effect is improved, the fruit setting rate and the fruit quality of the main cultivar are improved, and the uniformity of a pear garden is improved.
Further, the variety B and the variety C of the scion pear tree selected in the step (1) are pear trees which are weak in growth vigor, easy to form axillary flower buds, easy to form short fruit branches, high in variety and pollen.
Further, the flowering phases of variety A, variety B and variety C meet.
Further, if the pear flower of variety A has no pollen, variety A cannot pollinate variety B and variety C, or variety A has pollen, and varieties A, B and C pollinate each other.
The variety B and the variety C can pollinate the variety A, and the fruit setting rate and the high-quality fruit rate of the variety A are obviously improved. If the pear flower of the variety A has pollen, the variety A, the variety B and the variety C can be pollinated with each other.
Further, the variety A selected in the step (2) is a pear tree which is 1-2 years old and has a height of more than 2.4 m.
Further, grafting the variety B or the variety C at a position 2.2-2.4m away from the trunk of the variety A in the step (2).
Further, grafting the variety B or the variety C at a position 2.2m away from the trunk of the variety A in the step (2).
Further, grafting the variety B or the variety C at a position of 2.4m of the trunk of the variety A in the step (2).
Further, the variety B and the variety C grafted in spring in the step (3) germinate and sprout 2-3 new shoots in the current year.
Further, the top shoots of variety B or variety C were shortened 1/2 compared to the top shoots of variety A.
In order to ensure the quality and yield of the pear tree, the method needs at least 2 pear tree varieties to pollinate with each other in the whole garden, and ensures the fruit setting rate and the fruit quality.
Compared with the prior art, the invention has the following beneficial effects:
the method disclosed by the invention fixedly plants a main planting pear tree variety A in a whole garden, when the pear tree grows for 1-2 years, a variety B and a variety C with weak growth vigor are selected for high-position grafting, the variety B and the variety C pollinate the variety A in the second year, the variety B and the variety C pollinate each other, the fruit setting rate of each variety is high, the fruit shape is positive, the quality is high, the top end advantage of the pear tree is controlled, and the tree body is balanced vertically, internally and externally, so that a three-dimensional structure is formed. The growth of the tree body is regular and consistent, the field farming management is convenient, and a good foundation is laid for the high yield and the high quality of the pear tree.
