Embodiment

[0014] In the experiment in 2007-2008, the test material was Feizixiao lychee tree planted in April 2002, with a row spacing of 3×5 meters, and the crowns of the trees had been handed over. On November 18, 2007, the following three groups were treated with paclobutrazol:

[0015] ① Soil soaking: apply 5 grams of paclobutrazol and 10 catties of water per plant, dig a shallow trench with a depth of 10 cm 1 meter away from the trunk, pour the paclobutrazol solution and cover with soil;

[0016] ②Root system infusion: dig out 5 roots with a diameter of about 0.5 cm from each tree and cut them off, and insert them into mineral water bottles containing 1 gram of paclobutrazol and 500 ml of water. cover soil.

[0017] ③ Control: No treatment was used as the control.

[0018] Each group treated 4 trees.

[0019] In addition, on January 25, 2008, the first batch of flower spikes of 4 Feizixiao plants were wiped out; on March 30, 2008, the other 4 plants were taken for trunk girdling...

Abstract

The invention relates to a method for raising the fruit setting rate of Feizixiao litchi, which is characterized in that: during the flower bud physiological differentiation period of the Feizixiao litchi, a plurality of roots are dug out from different directions of the tree body, after being cut, each root is respectively inserted into a mineral water bottle which is filled with the water solution containing 1g of commercial paclobutrazol, and then the bottle is covered with water. By utilizing the mineral water bottle to carry out paclobutrazol root system infusion on the Feizixiao litchi,the method can remarkably increase fruit setting rate, and has low cost, low dosage, simple operation and no pollution to soil.

Description

technical field [0001] The invention belongs to a method for improving the fruit setting rate of litchi, especially Feizixiao litchi. Background technique [0002] Litchi is one of the important subtropical fruits in my country. In 2006, the national annual output was about 1.35 million tons, and the number of people who planted it plus related industrial chain employees reached 5 million. Among all litchi varieties, Feizixiao is a well-known early-maturing variety, which has the advantages of good quality, easy flowering, early flowering, large flower volume, and strong cold resistance. But the low fruit setting rate is a weakness of Feizixiao litchi variety, which has seriously affected the further development of Feizixiao litchi variety. [0003] At present, the main methods to improve the fruit setting rate of Feizixiao litchi varieties are: [0004] 1. Manually erasing the first batch of flower spikes can reduce the amount of flowers, delay the flowering period, and p...
