Embodiment example 1
[0030] see Figure 1 to Figure 9 , the present invention provides a technical solution: a kind of pollination technology that improves the quality of Majia pomelo, comprising the following steps:
[0031] S1, select the Majia pomelo plant that normal growth is in fruiting stage;
[0032] S2, selection of pollen parents and preparation of pollen;
[0033] S3, open pollination.
[0034] The pollination technique for improving the quality of Majia pomelo specifically includes the following steps:
[0035] S1, choose the Majia pomelo plant that normal growth is in the fruiting stage: select the adult Majia pomelo tree that is normally grown in the local area and is in the fruiting stage;
[0036] S2. Selection of pollen parents and preparation of pollen: two local pomelo T1 and T2 varieties of close relatives were used as male parents, the main planted Majia pomelo was used as female parent, and natural pollination CK was set as control group; flowers that had not yet loosened ...
Embodiment example 2
[0048]Different cultivars of sister line, related line and distant line were selected as male parents to hybridize with Majia pomelo, referring to the above steps, to further explore the optimal hybrid combination to improve the fruit quality of Majia pomelo.
[0049] Specific implementation case data comparison:
[0050] 1. See Table 2 below. After cross-pollination with the pollen of closely related varieties, the weight per fruit and the number of seeds per fruit were increased and the thickness of the pericarp was reduced.

Abstract
The invention discloses a pollination technology for improving the quality of Majia pomelo. The pollination technology comprises the following steps: S1, selection of Majia pomelo plants which normally grow and are in a fruiting period; S2, selection of pollen parents and preparation of pollen; and S3, open pollination. According to the pollination technology for improving the quality of the Majia pomelo, firstly, artificial cross pollination is adopted, sister line, sibling line and distant line varieties are used as male parents, main cultivated Majia pomelo is used as female parents for artificial pollination, and natural pollination is used as a control. Analysis on pollinated fruits shows that the seed number, the single fruit weight, the edible rate and the like of the hybridized fruits are obviously increased compared with those of naturally pollinated fruits, meanwhile, the fruit acidity and the fruit peel thickness are reduced, and the fruit flavor and benefits are improved. The technology can be popularized to a Majia pomelo plantation, three to four directions of each mu can be selected to plant one thick-skin Majia pomelo as a pollination tree according to the factors such as the flowering phase and the seed number, and the technology has an obvious effect on increasing the yield and improving the quality of the Majia pomelo.
Description
technical field [0001] The invention relates to the technical field of pollination for the quality of Majia pomelo, in particular to a pollination technology for improving the quality of Majia pomelo. Background technique [0002] Majia pomelo has a long history of cultivation. It is a geographical indication product in Jiangxi Province and a pillar agricultural industry in Guangfeng County, Shangrao City. At the same time, Majia pomelo has won the dual certification of "National Geographical Indication Protection Products" and "Agricultural Products Geographical Indication Protection", and has the reputation of "Top Ten Boutique Fruits in East China" and "Chinese Famous Fruits". Since 2009, Guangfeng County has vigorously promoted the development of the Majia pomelo industry, and the city's existing Majia pomelo planting area exceeds 25,300 hm 2 , of which the cultivated area in Guangfeng County reached 13,300 hm 2 , with a total output of 40,000 tons. The shape of Majia...
