Pollination method for kiwifruit

Abstract

The present invention relates to a pollination method for kiwifruit. The method is as below: collecting male flowers, taking out the anthers, opening the anthers to spread the pollen in a constant temperature illumination box at about 22-25 DEG C, sieving out the pollen by a finer basket of 80 mesh, filling the selected pollen into a clean colored glass bottle, storing in a dry refrigerator at low temperature for usage at any time; at the same, preparing 2000ml of a suspension liquid by adding 1g of agar, 50g of sucrose and 0.1g of boric acid in a large glass bottle, adding 200ml of purified water, heating to melt, and then diluting with 1800ml of purified water; and preparing a pollen suspension liquid in a ratio of 1:300, spraying the suspension liquid to the pistil stigma in the middle of a blossom female flower by using a hand-operated small watering can until fluid suspension dew stays on the pistil stigma, so as to complete pollination. The method provided by the invention has good pollination effect and multiple fruit seeds after pollination, so as to improve fruit rate, and effectively improve the fruit quality and marketability.

Description

technical field [0001] The invention relates to a kiwifruit pollination method, which belongs to the kiwifruit cultivation technique and is suitable for the pollination management of the kiwifruit. Background technique [0002] Kiwi fruit is originally produced in my country, and its wild resources are very rich. There are 54 species in the genus Actinidia, and 52 species in my country, of which 44 are endemic to our country; "Ward" and other varieties were gradually commercialized and cultivated in the 1930s and 1940s. Due to the unique climate and soil conditions, they developed into industries and were exported to countries all over the world. At present, the countries that cultivate more in the world are mainly New Zealand, Italy, Chile and so on. my country's kiwifruit cultivation has a long history, but the commercial development and utilization of kiwifruit is relatively late. As a commercial cultivation, there was only a small amount of cultivation in my country in t...

Problems solved by technology

Due to its unique resources, although the research on kiwifruit started relatively late, it developed rapidly. By 2011, my country's kiwifruit cultivation area and output both ranked first in the world. Due to the lack of reasonable cultivation techniques, the quality of kiwifruit fruit cannot adapt to the market. It lacks competitiveness in the international market. At present, the main origin of high-quality kiwifruit in the international market is New Zealand.

An important factor affecting the quality of kiwi fruit is the size of the fruit. The size of the fruit is not only related to the characteristics of the variety, but also has a close relationship with the cultivation technology, especially the pollination technology of kiwi fruit. and delicious kiwifruit, and these two kinds of kiwifruit are mostly dioecious, and they must be pollinated to bear fruit, and the quality of pollination directly affects the size of the fruit. Natural pollination and insect pollination are likely to cause poor pollination, and the number of fruit seeds is small, resulting in small fruit size. Fruits and odd-shaped fruits seriously affect the yield and economic benefits

In the process of cultivation and management in various parts of my country, the pollination techniques are different. Some use artificial pollination for pollination, and some use peak pollination. For large-scale cultivation of kiwifruit, due to labor force factors, artificial pollination is relatively extensive and the effect is not ideal, resulting in fruit failure. The size is not uniform, and there are odd-shaped and small fruits, which seriously affect the yield and commerciality of the fruit, thus directly affecting the economic benefits
