First, train healthy results mother branch
After a large number of fruiting branches of Guizhi Litchi, the tree vigor is more difficult to recover, and the leaves are easily changed to light yellow, which affects the photosynthesis and the ability of the roots to absorb water and suck up fertilizer. The first shoots are irregular, the internodes are short, and the leaves are thin. Poor quality. Even affect the second and third shoots of germination and timely maturity, resulting in poor bud development and difficult flowering. Therefore, we must grasp fertilizer and water management, determine the type and quantity of fertilization according to tree vigor, ensure that the last shoot is extracted in mid-to-late October, and mature in early December to facilitate the formation of pure spikes.
1, timely application of quick-effect fertilizer
2, mild retraction trim
3, timely application of organic fertilizer
Second, do a good job of controlling flowers
1, timely put autumn shoots
2. Using a small amount of winter shoots to adjust the balance of reproductive growth and nutritional growth in the following year
3, artificial and drug control
Third, take timely measures to protect fruits and fruits
The early growth stage of Guizhi Litchi flower ear is more susceptible to the temperature affecting the emergence of leaflets, which is also one of the reasons for the low flowering rate and fruit setting rate of Guiwei.
1, the application of spiral ring stripping technology
2, timely application of strong fruit fertilizer
3, spraying enhanced leaf photosynthesis
4, appropriate control of the amount of fruit
Fourth, timely harvest
The taste of Guiwei fruit is easy to taste, too late harvest affects the quality, and at the same time affects the restoration of tree vigor. It should be timely and fully picked to ensure the unique flavor of the fruit and reduce the impact on the tree.
