Artificial pollination method of kiwifruit and preparation method of kiwifruit pollen used

Abstract

The invention discloses a preparing method of kiwi fruit pollen. The method includes the following steps: (1) male plants and female plants are configured according to the quantity ratio of 19-21:1, the male plants are cultured in a facility greenhouse, and the female plants are cultured in a field through shed frames; (2) after the male plants enter a flowering period, male flowers which are to blossom are selected, anthers in the male flowers are taken out, spread, dried and crushed, and then the kiwi fruit pollen is obtained; (3) the storage period of the kiwi fruit pollen is 1 week at a normal temperature, and the storage period of the kiwi fruit pollen is 30-40 days at a refrigerated storage temperature. The invention further discloses a kiwi fruit artificial pollination method, wherein artificial pollination is carried out by means of the kiwi fruit pollen in the storage period after female flowers enter a flowering period. The kiwi fruit artificial pollination method includes that in the early stage of blossoming, a point pollination method is adopted through a pollination pen, and a dry powder spraying method is adopted through a spraying-type pollination device in a full-blossom period. According to the kiwi fruit artificial pollination method and the preparing method of the kiwi fruit pollen, the high fruit setting rate and the high fruit quality in kiwi fruit production are guaranteed.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a kiwifruit pollen production technology and an artificial pollination operation method. Background technique [0002] Kiwi fruit is rich in nutrition, rich in vitamin C and various trace elements. Its flesh is tender, rich in aroma, sweet and refreshing in taste, and extremely low in acidity. It is known as "magic and delicious fruit". In recent years, the development speed of kiwi fruit in my country is very fast, and the current national planting area has reached more than 500,000 mu. Existing kiwi fruit is a mixed cultivation mode of male and female plants at present, that is, it is all conventional field scaffolding cultivation. [0003] Since kiwifruit is a dioecious plant, artificial pollination is a necessary measure in order to obtain higher yields and high-quality fruits in production, especially since the flowering period of kiwifruit is short, it is difficult t...

Problems solved by technology

[0003] Since kiwifruit is a dioecious plant, artificial pollination is a necessary measure in order to obtain higher yields and high-quality fruits in production, especially the flowering time of kiwifruit is short, and it is difficult to ensure high-quality and high-yield by relying on natural pollination

However, in actual production, the flowering time of male and female kiwifruit plants is often affected by different climatic conditions, and they do not meet each other, resulting in no pollen or pollen but the female plant does not bloom during artificial pollination.

In addition, since the flowering duration of kiwifruit is about 7 days, and the best pollination time for female flowers is only 2 to 3 days, the workload of artificial pollination is heavy, and it is more difficult to pollinate if flowering occurs during rainy periods. This defect becomes more prominent
