Method for promoting advancing maturity of navel orange No.52

Abstract

The invention discloses a method for promoting advancing maturity of a navel orange No.52. According to the invention, the murcott orange with natural pollination has the special natural cross-pollination function; the murcott and the navel orange No.52 are planted in a hybrid mode, wherein the flowering phase of the murcott is identical with that of the navel orange No.52; and with natural pollination of mediums like bees, insects, and wind and the like, excellent characteristics of high glucose and high quality of the murcott orange are expressed and inherited by the navel orange No.52. Fifty navel oranges No.52 are planted per 666.7 square meters at an orchard and three murcott oranges are planted in a hybrid mode at equal distances; a box of bees are kept each 333.5 to 4000.2 square meters, small channels formed by iron gauzes are arranged at the inlet and outlet of the bee box, and newly-bloomed flowers of the navel oranges No.52 and the murcott oranges are placed in the channels, wherein the flowers are mixed with a little honey, so that signals for pollen collection of the navel oranges No.52 and the murcott oranges are sent to the bees. On the basis of the technical scheme, maturity of the navel oranges No.52 can be realized 30 to 40 days in advance and the soluble solid content of the fruit can reach up to over 15.4%. Therefore, the navel orange No.52 becomes the earliest one being on sale on the market and the one with the best quality; and the available price can be improved by 1.5 times.

Description

technical field [0001] The invention belongs to the field of fruit trees, and in particular relates to a method for promoting early maturation of navel orange 52. The method uses citrus varieties with cross-pollination function to realize early maturation of navel orange 52. Background technique [0002] Fruit trees are divided into two types: cross-pollination and self-pollination. Cross-pollination fruit trees such as apples and pears must be equipped with pollination trees in order to obtain high yields. Pollination trees are widely used. Citrus is a self-pollinating fruit tree, and high yields can be obtained without the need for pollination trees in production. The cross-pollination of citrus can improve the quality of fruit and improve the comprehensive traits. However, because citrus is a complete flower, a flower has stamens and pistils, and foreign pollen is completely rejected. Artificial cross-pollination must first carefully remove the stamens with tweezers, an...

Such artificial pollination is time-consuming, labor-intensive, costly, and unacceptable in production

The cross-pollination of citrus is still in the experimental stage of artificial pollination. Up to now, no citrus pollinated varieties have been reported to be naturally pollinated by bees, insects, wind and other media, so it is very important to find such citrus varieties. Once discovered, the quality of citrus can be improved in a short period of time, the comprehensive traits of citrus can be improved, the maturity period can be advanced, and the market demand can be met.

[0003] The earliest ripe citrus in our province is Wenzhou Satsuma, which was launched in October. Its quality is relatively poor, and its soluble solid content (the main indicator of quality) is only 9-10%, which cannot meet the market's demand for high-quality citrus.
