Embodiment 1

[0029] Experimental time: early March.

[0030] A method for regulating litchi flowering and fruiting, comprising the following steps:

[0031] On March 9, when the flower spikes of the potted Xianjinfeng lychee tree were 8 cm long, the potted Xianjinfeng lychee tree was moved to the artificial climate room with natural light supplementation, and the temperature was 8°C, and the light intensity was 0.5 million Lux for cultivation. Stop the flowering process of lychees; spray a compound foliar fertilizer every 15 days during this period. The compound foliar fertilizer solution is an aqueous solution, which is added with paclobutrazol 0.1g / L, nucleotide 0.3g / L, potassium dihydrogen phosphate 0.3g / L, zinc sulfate 0.1g / L and magnesium sulfate 0.2g / L / L.

[0032] When it is necessary to promote the flowering of litchi, on June 20, the temperature of the artificial climate chamber with natural supplementary light was raised to 27°C, and the light intensity was 40,000 Lux, so that ...

Embodiment 2

[0036] Experimental time: early March.

[0037] A method for regulating litchi flowering and fruiting, comprising the following steps:

[0038] On March 9, when the flower spikes of the potted Xianjinfeng lychee tree were 5 cm long, the potted Xianjinfeng lychee tree was moved to the artificial climate room with natural light supplement, and the temperature was 5°C, and the light intensity was 0.5 million Lux for cultivation. The flowering process of stagnation litchi; Spray compound type foliage fertilizer once every 20 days during; Compound type foliar fertilizer solution is aqueous solution, adds paclobutrazol 0.2g / L, nucleotide 0.3g / L, phosphoric acid Potassium dihydrogen 0.3g / L, zinc sulfate 0.1g / L and magnesium sulfate 0.2g / L.

[0039] When it is necessary to promote the flowering of litchi, on October 10, the temperature of the artificial climate chamber with natural supplementary light was kept at 25°C, and the light intensity was 30,000 Lux, so that the flower buds o...

Abstract

The invention discloses a method for regulating and controlling blossoming and fruiting of litchis. According to the method, flower buds on litchi flower spikes can bloom only after temperature accumulation at the growth temperature for 150-1900D. After the litchis bloom, the litchis need to be subjected to temperature accumulation of the growth temperature for 700-9000D and then can be ripe. By setting specific temperature and illumination, the blossoming and fruiting time of the litchis can be regulated and controlled, the litchis can bloom at specific time nodes, and maturation of the litchis at any time node such as the national celebration festival and the Spring Festival is achieved; and the average fruit setting rate is improved. The method for regulating and controlling blossomingand fruiting of the litchis has great scientific research value, ornamental value and economic value.

Description

technical field [0001] The invention relates to the technical field of litchi production, in particular to a method for regulating the flowering and fruiting of litchi. Background technique [0002] Litchi is a subtropical characteristic fruit mainly produced in southern my country such as Guangdong, Guangxi, Fujian, Yunnan, and Hainan. Sichuan, Guizhou and other places have very few microclimate environments, and a small amount of it is planted. According to different varieties and climatic conditions, litchi usually blooms from November to May of the following year, and the fruit ripening period is from April to August every year. [0003] my country's Hainan Province is the earliest mature area for lychees, which begin to mature in April every year; the latest mature area is Luzhou City, Sichuan Province. There is only a small area in Luzhou City that can grow lychees by using the microclimate environment, and it can be grown at the latest every year. Ripe until the end o...
