A method for promoting fruiting of winter citrus citrus

Abstract

The invention discloses a method for promoting winter shoot fruiting of orah, and relates to the technical field of planting. The method comprises the following steps: spraying a potassium nitrate solution on a winter shoot until the surface of the winter shoot is wet in the middle of December, spraying a mixed liquid medicine on the surface of the winter shoot until the surface of the winter shoot is wet after the surface of the winter shoot is dried, and spraying the potassium nitrate solution and the mixed liquid medicine once every 10-15 days for three times; preparing the mixed liquid medicine mainly by mixing organic polypeptidase, amino-oligosaccharin and water in a weight ratio of 0.4 to 0.2 to 600-800; spraying an anti-freezing agent on the whole tree crown of the orah after the mixed liquid medicine is used for 1-3 days each time, and the anti-freezing agent comprises the following raw materials: extracts of radix ophiopogonis, soybean polypeptide, alanine, cysteine, potassium dihydrogen phosphate and water. According to the method for promoting winter shoot fruiting of orah, after the method is adopted, for the winter shoot, the branch is strong, the leaves are thick andturn green fast, the maturity is rapid, the flower bud differentiation is normal, so that the winter shoot can fruit in the next year with the same as an autumn shoot.

Description

【Technical field】 [0001] The invention relates to the technical field of planting, in particular to a method for promoting winter shoot fruiting of citrus citrus. 【Background technique】 [0002] Orah is a hybrid of Temple orange and Danxi tangerine. It comes from Israel. It has the advantages of strong tree vigor, beautiful fruit appearance, high quality, late maturity and high sugar, early knot and high yield, and high selling price. Over the past few years, it has grown to more than 1.5 million mu, and the annual growth rate is 200,000 to 300,000 mu, which is the fastest growing variety in the history of citrus planting in my country. The new shoots of citrus before and after the beginning of winter are called winter shoots, and the spring, summer, autumn and winter shoots of citrus can become fruiting mother branches under the conditions of sufficient maturity and sufficient nutrition. Wo citrus grows fast. Generally, after the last batch of shoots mature, a large number ...

AI Technical Summary

Problems solved by technology

Wo citrus grows fast. Generally, after the last batch of shoots mature, a large number of winter shoots will be drawn out when the temperature is suitable, the water is abundant, and the nutrition is too rich. Because the winter shoots are not easy to mature, they are prone to freezing damage at low temperatures, and the next year will be large. Part of the characteristic of not being able to bloom, the general method is to spray paclobutrazol or ring cutting to inhibit the germination of winter shoots when the autumn shoots turn green quickly. Ripe them before cooling down, but it is time-consuming and labor-intensive, especially for orchards with large planting areas that lack manual work, and improper erasure operations may make more and more of them, but before cooling down, they can only be partially ripened, and the ripening In the second year, the shoots bear less fruit and severe fruit drop
