Embodiment 1

[0040] A kind of artificial pollination method of small female parent litchi tree

[0041] (1) Select a lychee tree with good traits, strong spikes and neat growth as the female parent.

[0042] (2) Build a scaffolding, the scaffolding structure is as follows figure 1 and figure 2 shown. The scaffold material can be steel pipe or bamboo pole. Insert the steel pipe or bamboo pole into the soil at a depth of about 1m. The top of the scaffold is designed as a raised (ie protruding) structure, such as an umbrella shape.

[0043] (3) Before the female flower of the female parent tree blooms, cover the whole lychee tree with gauze on the scaffolding, and compact it with soil around it, leaving an exit for pollinators to enter and exit.

[0044] (4) Spray high-efficiency insecticides and high-efficiency fungicides in the net room, that is, spray insecticides and fungicides to ensure that there are no bees and other pollinating insects in the shed, and prevent the occurrence of di...

Embodiment 2

[0048] A kind of artificial pollination method of medium and large female parent litchi trees:

[0049] (1) Select a lychee tree with good characters, strong spikes, and neat growth as the female parent.

[0050] (2) Build a scaffolding, the scaffolding structure is as follows image 3 shown. All scaffolding materials are steel pipes, and the steel pipes are inserted into the soil at a depth of about 1m. According to the location where the lychee flower spikes grow, build one-, two-, or multi-layer steel frames at a suitable height. A plurality of steel network bridge plates are placed between different steel pipes of each steel frame, and the top of the scaffold is designed as a raised (ie protruding) structure.

[0051] (3) Before the female flower of the female parent tree blooms, cover the whole lychee tree with gauze on the trellis, and compact it tightly with soil around it, leaving an exit for pollinators to enter and exit.

[0052] (4) Spray high-efficiency insecti...

Abstract

The invention belongs to the technical field of fruit tree pollination, and particularly relates to an artificial pollination method for litchi. The method comprises the following steps: (1) selecting a female parent litchi tree; (2) building a shed frame, and covering the shed frame with a gauze to form a net house to cover the whole litchi tree; (3) spraying insecticide and antibacterial agents in the net house of the shed frame; (4) during the blooming period of female flowers of the female parent tree, performing artificial pollination; (5) after the pollination operation is completely finished, removing the gauze, observing whether a second batch of female flowers are bloomed in the later stage, and picking off a second batch of small fruits in time. A bagging procedure is avoided, the method is easy to operate, time-saving and labor-saving, and the damage to the female flowers and leaves of the litchi is also avoided; a litchi breeder can harvest a great number of hybridization seedlings every year, the artificial pollination efficiency of the litchi is greatly improved, the occurrence probability of a target strain is improved, the hybridization breeding term of the litchi is indirectly shortened, and the artificial hybridization breeding progress of the litchi is accelerated.

Description

technical field [0001] The invention belongs to the technical field of fruit tree pollination, and in particular relates to a method for artificial pollination of litchi. technical background [0002] Litchi fruit is rich in nutrition and unique in flavor. It is one of the most important economic fruit trees in Guangdong, Guangxi, Hainan, Fujian and other provinces. At present, the structure of litchi cultivars is seriously irrational, and the problem of concentrated production period is prominent. Realizing variety innovation is an important means to solve the problem. All along, the acquisition of new varieties of litchi mainly comes from seed selection. Due to the continuous cutting of litchi resources, the singleness of cultivated varieties has become more and more prominent, and the variation of litchi seeds has become less and less. It is difficult to realize the innovation of litchi varieties through seed selection. Artificial cross-breeding will become the main wa...
