Embodiment 1

[0017] The present embodiment provides a kind of method that improves single fruit weight of feizixiao litchi fruit, comprises the steps:

[0018] S1. At the beginning of February, after the flower spikes of Feizixiao Litchi were drawn out, the flowers were thinned manually, and only one flower spike at the base of the flower spike was kept, and the rest were all thinned out;

[0019] S2. Cover it with a plastic greenhouse for about 20 days, and keep the temperature inside the greenhouse at 25°C-27°C (at this time, the temperature outside the shed is usually only 15°C-20°C). The increase in the temperature inside the shed promotes the growth and development of flower spikes , prompting all the female flowers of the litchi spikes to bloom at the end of February;

[0020] S3. During the flowering period, honeybees are used to assist pollination. After pollination and fertilization, the plastic greenhouse is removed, and the fruit continues to grow and develop in a natural state ...

Embodiment 2

[0022] This embodiment aims to further illustrate the effectiveness of the method in embodiment 1 through experiments.

[0023] Experimental group: In Feizixiao Orchard on February 5, 2013, artificial flower thinning was carried out on Feizixiao flower spikes, only one flower spike at the base of the flower spike was kept, and the rest were thinned out, and then covered with a plastic greenhouse. At 25°C-27°C, the temperature outside the shed is only 15°C-20°C. The increase in the temperature inside the shed promotes the growth and development of flower spikes. All female flowers bloom from February 24th to February 26th. During the flowering period, bees are used to assist pollination After pollination and fertilization, the plastic greenhouse was removed on February 28, and the fruit continued to grow and develop in a natural state. By May 26, the fruit was ripe, and the average fruit weight of the fruit reached 28.9 grams, the soluble solid content was 20.2%, and the average...

Embodiment 3

[0026] This embodiment aims at another experiment to further illustrate the effectiveness of the method in embodiment 1.

[0027] Experimental group: In Feizixiao Orchard on February 10, 2014, artificial thinning of Feizixiao flower panicles was carried out. Only one flower spike at the base of the flower spike was kept, and the rest were thinned out, and then covered with a plastic greenhouse. The temperature in the greenhouse At 25°C-27°C, the temperature outside the shed is only 15°C-20°C. The increase in the temperature inside the shed promotes the growth and development of flower spikes. All female flowers bloom from February 26th to February 28th. During the flowering period, bees are used to assist in pollination After pollination and fertilization, the plastic greenhouse was removed on March 2, and the fruit continued to grow and develop in a natural state. By May 29, the fruit was ripe, with an average fruit weight of 29.2 grams, a soluble solid content of 20.4%, and a...

Abstract

The invention discloses a method for increasing the weight of Feizixiao lychees per fruit. The method includes the following steps: S1, after the Feizixiao lychees have spikes in early February, manually thinning flowers, only retaining one spike at the root of each flower, and removing residual spikes; S2, covering the spikes with a plastic greenhouse, and keeping the internal temperature of thegreenhouse at 25-27 DEG C, wherein the growth and development of the spikes are promoted through temperature rise in the greenhouse, and all female flowers of the lychee spikes are promoted to flowerin late February; and S3, in the flowering stage, applying bee-assisted pollination, removing the plastic greenhouse after pollination and fertilization, and allowing fruits to grow and develop in a natural state until ripening. The method has the advantages that through a high-temperature environment in the greenhouse, development of lychee buds and early flowering are promoted; after pollinationand fertilization, the fruits further develop and ripen under a natural-temperature environment, and accordingly, the weight of the lychees per fruit is increased.

Description

technical field [0001] The invention relates to the technical field of cultivation of Feizixiao litchi, in particular to a method for increasing the single fruit weight of Feizixiao litchi. Background technique [0002] In the natural state, Concubine Xiao in Guangzhou area begins to show white spots in the middle and late December, and flower spikes emerge in early February, and a very small number of female flowers bloom at the end of February, forming early flowering fruits, but the proportion is less than 5%, and most of the female flowers are in 3 It blooms in the middle and late months, accounting for more than 95%, forming Feizixiao late-flowering fruits. The average single fruit weight of early-flowering fruits is more than 32 grams, and the average single fruit weight of late-flowering fruits is 21 grams. Early-flowering fruits are about 50% larger than late-flowering fruits. The ripening period of early flowering fruit is late May, with a soluble solid content of 2...
