Greenhouse cultivation method of apple pears, apple pears and tea for reducing three highs

Abstract

The invention belongs to the technical field of tree cultivation, and discloses a greenhouse cultivation method of apple pears, the apple pears and a tea for reducing three highs. From fruits in the myrtle family and psidium guajava, an apple pear species is selected through experimenting in a northern greenhouse to culture grafting and planting seedlings, and field planting is conducted; soil improvement, seedling recovering and seedling accelerating are conducted; after seedling recovering, fruit setting is conducted in florescence, and topping is conducted on the portion, between two opposite leaves, above each branch flower bud to generate branches and buds. Pear trees cultivated through the method bear fruits three months earlier, the equality is good, the fruits are big, the taste isgood, and the trees can be planted nationwide, while traditional apple pear trees can only be planted in the south; by means of the method, the problems are solved that the apple pear trees cannot beplanted in the north or be planted or cultivated in areas with the temperature lower than 5 DEG C in winter, the yield is low, lignification happens to fruits, the surfaces of the fruits are not smooth, and the sugar content is low.

Description

technical field [0001] The invention belongs to the technical field of arboriculture, and in particular relates to a greenhouse cultivation method of Siji pear, Siji pear and Jiangsangao tea. Background technique [0002] In the prior art, this kind of fruits and vegetables can only grow in places with high temperature in the south, and they are open-air, relatively affected by the weather, the sugar content of the fruit is not high, the fruit is seriously lignified, the management cost is high, and the pests and diseases are serious. [0003] In summary, the problems in the prior art are: the pear trees cultivated in the prior art cannot be planted and cultivated in areas below 5 degrees, the yield is low, the fruit is lignified, and the fruit surface is not smooth and contains less sugar. The difficulty of this problem solution is to select seedlings and solve the problem that it cannot be planted below 5 degrees. Contents of the invention [0004] Aiming at the problem...

Problems solved by technology

[0002] In the prior art, this kind of fruits and vegetables can only grow in places with high temperature in the south, and they are open-air, relatively affected by the weather, the sugar content of the fruit is not high, the fruit is seriously lignified, the management cost is high, and the pests and diseases are serious.

[0003] In summary, the problems in the prior art are: the pear trees cultivated in the prior art cannot be planted and cultivated in areas below 5 degrees, the yield is low, the fruit is lignified, and the surface of the fruit is not smooth and contains less sugar.

The difficulty of solving this problem lies in the selection of seedlings and the solution that it cannot be planted below 5 degrees.
