Problems solved by technology

Because different lychee and longan varieties have different sensitivity to the above plant growth regulators, if ethephon is used at an improper concentration, it will easily cause damage to the old leaves of lychee and longan. In severe cases, it will cause leaf fall and affect the flowering of next year.

Embodiment 1

[0016] In Supeng Fruit Farm, Jiulong Town, Qinzhou City, Guangxi, the lychee planting area is 30 mu, including 24 mu of Concubine Xiao and 6 mu of Double Shoulder Jade Purse. In 2014, the method of the present invention was used to control shoots and promote flowering of the Shuangjianyuhebao variety. In 2015, the flowering plant rate reached more than 90%, and the fruit ears were compact and the fruit setting rate was high. It is estimated that the fruiting yield per plant can reach 25-40kg.

[0017] In the control experiment, the lychee variety is Feizixiao, spraying ethephon and paclobutrazol to control shoots and promote flowering according to the traditional method. In 2015, early flowering and partial shoot shoots were produced. The rate of flowering and fruiting plants was 65%, and the yield was not ideal.

Embodiment 2

[0019] Liangfengjiang Litchi Garden in Nanning City, Guangxi, with an area of ​​50 mu. The variety is Jizui Litchi planted in 1997. In 2014, the method of the present invention was used to control shoots and promote flowering on 5 mu. In 2015, the flowering rate reached 82%. Moreover, the fruit ears are compact and the fruit setting rate is high. It is estimated that the yield per plant can reach 30-50kg, reaching a very high yield level.

Embodiment 3

[0021] In 2014, the method of the present invention was used to conduct a shoot-controlling and flower-promoting test on the longan of the teaching and scientific research base of Guangxi University. In 2015, the test tree flowering rate reached more than 95%, and the current fruit-bearing condition is good.

Abstract

The invention belongs to the technical field of fruit tree cultivation and particularly relates to a shoot controlling and blossom promoting method for litchi chinensis and euphoria longan. The shoot controlling and blossom promoting method for the litchi chinensis and euphoria longan is characterized by comprising the following steps: (1) picking litchis and longans, and then, drawing autumn shoots for 2-3 times according to the requirements of different varieties on stage of flower bud differentiation, wherein the time after last-time autumn shoots fruit and mother branches turn green or aged is a shoot controlling period; and (2) then, spraying a suspension, of which the volume is 500-1,000 times that of 25% flumetralin, of 25% flumetralin to leaves of the litchi chinensis and euphoria longan once in the shoot controlling period. The method disclosed by the invention has the advantages that the germination of winter shoots of the litchi chinensis and euphoria longan can be effectively inhibited, the flower bud differentiation is promoted, the blossoming and fruiting of the litchi chinensis and euphoria longan are realized, and the percentage of fertile fruit and yield of the litchi chinensis and euphoria longan can be increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and specifically relates to a method for controlling shoots and promoting flowers of litchi and longan. Background technique [0002] Flumetriamine is a dinitroaniline compound, a new type of plant growth regulator, and a contact and local systemic high-efficiency bud inhibitor. It mainly inhibits cell division at the top (side) bud growth point, and has a strong effect. The drug has a low residue in the leaves and is widely used in tobacco and cotton crops. [0003] There is a contradiction between the winter season of litchi and longan and the flowering and fruiting. Controlling the winter shoots is conducive to promoting the flowering and fruiting of litchi and longan. At present, plant growth regulators such as paclobutrazol, uniconazole, ethephon and B9, and agricultural techniques (girdling, root cutting) are usually used in most litchi and longan producing areas as a metho...
