Problems solved by technology

However, the branches need to be cut off during grafting, which means that there will be no harvest for two or three years for the older litchi trees that have bear fruit, which will affect the enthusiasm and economic benefits of fruit farmers.

specific Embodiment

[0018] Management before grafting: choose lychee trees that are more vigorous and 10 years old, and deep plowing and fertilization are required from 1 to 3 months before grafting. That is, in the 40-60 cm tree tray within the drip line of the crown, plow 10-20 cm deep, and apply farmyard manure evenly according to the age of the tree and the size of the crown. If the weather is dry, it needs to be irrigated to keep the soil moist, so that the litchi grows vigorously, accumulates nutrients, improves the survival rate of grafting, and allows the scion to grow rapidly.

[0019] Scion preparation: The scion should be cut and harvested on the young fruiting trees that grow vigorously, preferably the peripheral branches that are thick in the middle and upper part of the canopy and full of axillary buds. Cut off the tops of the fruiting tree growth branches first, and pick them immediately after 5 to 7 days when the axillary buds on the branches are full, and the survival rate is the...

Abstract

The invention provides a litchi grafting method. The litchi grafting method includes the steps of management before grafting, scion preparation, grafting time, rootstock cutting, scion cutting, bundling, supplementary grafting, anvid bud removal, unbundling, nutrient and water management, prevention and control of diseases and pests and the like. Middle rootstocks are selected for grating, so that graft survival rate can reach up to 90%, varieties of litchi fruit can be effectively improved, grafting is performed in early spring and blossom and fruit yielding are achieved in the following spring, and the litchi trees enter the high-yield period after being grafted for 3-4 years; sufficient light and ventilation of low trees are guaranteed, the low trees steel fruit normally during grafting, fruit quality is higher, and economic effectiveness is guaranteed.

Description

technical field [0001] The invention relates to fruit tree grafting technology, in particular to litchi tree grafting technology. Background technique [0002] At present, there are many varieties of litchi, many of which are low-yield and low-quality varieties. In order to transform the structure of litchi varieties, grafting techniques are generally used to transform low-yield and low-quality litchi into high-quality litchi varieties such as Guiwei, Nuomici or Feizixiao. However, the branches will be cut off during grafting, which will mean no harvest in two to three years for the older lychee trees that have produced fruit, which will affect the enthusiasm and economic benefits of fruit farmers. Contents of the invention [0003] The invention provides a litchi tree grafting method, which is easy to operate and has a high survival rate. The grafting is mainly based on intermediate rootstocks, low branches can continue to bear fruit, and harvests can still be obtained du...
