Abstract

The invention provides a method for advancing the ripening of waxberry fruits, which comprises the following specific implementation modes: 4-15g of sodium selenite is applied to the rhizosphere 35-38 days before the mature picking period of the waxberries according to the tree ages and the sizes of tree crowns, and 3-6ppm of sodium selenite aqueous solution is sprayed to the leaf surfaces of the waxberries according to the strengths of the trees after the rhizosphere is fertilized for 2-3 days. The implementation method is simple, the cost is low, the development and the maturity of the waxberry fruits can be remarkably promoted, and the fruit picking period is advanced by 3-5 days; has obvious economic benefit.

Description

Method for advancing fruit ripening of waxberries

Technical Field

The invention belongs to the technical field of fruit and vegetable planting, and particularly relates to a method for advancing the ripening of waxberry fruits.

Background

waxberry (1)Myrica rubra Sieb. &Zucc.) is a perennial subtropical evergreen fruit tree of the genus myrica of the family myricaceae, native to the southeast of the country, and has been cultivated artificially for over 2000 years. China has rich bayberry germplasm resources, and the bayberry germplasm resources are widely distributed in regions in the south of Yangtze river watershed such as Zhejiang, Fujian and Jiangsu. The waxberry has bright color, sour and sweet taste and high nutritive value, contains rich bioactive substances such as antioxidant substances and anticancer substances, and is popular with consumers at home and abroad for many years.

In China, most of the waxberry varieties bloom in 3 months and 4 months, and the fruits mature in 6 months and 7 months. The early maturing bayberry variety Fujian southern area, the blossom period is in the first ten days of 2 months, the fruit maturity period is in the first ten days of 5 months, the good quality and early maturity period of the fruit are the main early maturing bayberry variety which is circulated and sold in the same-period market, the price of each kilogram of early fruits reaches 200 yuan, the prices are sequentially decreased from early to late in the maturity period to the middle ten days of 5 months, and the price of each kilogram of bayberry fruits is usually reduced to 5-8 yuan, so that the method for advancing the maturity period of the early maturing bayberry variety can bring great benefits to fruit growers, and has quite considerable social and economic benefits.

At present, the early maturing cultivation technology of the waxberries is mostly greenhouse cultivation, and is assisted by condition control such as temperature, humidity, illumination and the like, but the method is high in cost and is not easy to master by general fruit growers; or plant growth hormone and the like are sprayed outside roots to promote the fruit ripening of the waxberries, and although the method can promote the pulp color of the waxberries to reach the ripening color, the sweetness is still kept at a lower level, the mouthfeel is poor, the quality is low, the waxberries are not easily accepted by consumers, and meanwhile, the tree bodies are damaged due to improper operation. The method for promoting the waxberry fruit to mature in advance is simple and easy to implement, low in cost and high in fruit farmer acceptance degree, can ensure the quality of the waxberry fruits, and has important significance for the waxberry industry.

Disclosure of Invention

The invention aims to provide a method for maturing waxberry fruits in advance aiming at the problem that the maturation period of the waxberry fruits is too concentrated and the economic benefit of the waxberry fruits is influenced.

In order to achieve the purpose, the invention adopts the following technical scheme:

A method for promoting fruit ripening of waxberries in advance comprises the following specific implementation modes:

Applying sodium selenite to the rhizosphere before the mature picking stage of the waxberries, and spraying a sodium selenite aqueous solution to the leaf surfaces at the same time.

Wherein, the time of rhizosphere fertilization is 35-38 days before the picking period, and the spraying time is 2-3 days after the rhizosphere fertilization;

The rhizosphere fertilizer is applied in an amount of 4-15g, and the application method is that the rhizosphere fertilizer is uniformly applied in tree crown drip after being dissolved by clear water; the concentration of the foliage spray is 3-6ppm, and the application method is to spray the foliage of the waxberry trees by taking the wetting degree of the foliage.

the waxberry variety is an early-maturing waxberry variety, and the benefit is remarkable.

The invention has the advantages that: in the development process of the waxberry fruits, the waxberry fruits are promoted to mature only by applying to the rhizosphere of the waxberry trees and spraying sodium selenite on the leaf surfaces, so that the maturation time of the waxberry fruits is advanced by 3-5 days; bringing remarkable economic benefit. In addition, the method is simple and feasible, and is very suitable for popularization and application in fruit growers.

Detailed Description

Example 1

1, 7-year-old Fugu 1 waxberry with crown width of 1.8 x 2.0m, wherein 4 g of sodium selenite is applied to the rhizosphere 35d before the mature picking stage, and the application method is that the sodium selenite is dissolved by clear water and then uniformly sprayed into tree crown drip; spraying 6ppm sodium selenite solution 2 days after rhizosphere fertilization, wherein the application method is to spray the leaves of the waxberry trees, and the leaves are wet; and carrying out normal production management, wherein the comparison is similar crown width trees of the same-age trees, and spraying clear water. The fruit can be ripe 5 days earlier, and the economic benefit is more than 3 times of that of the control.

Example 2

The red bayberry No. 1 which grows in 15 years has the crown width of 4.1 x 4.3m, 15g of sodium selenite is applied to roots 36d before the mature picking period, and the application method is that the sodium selenite is dissolved by clear water and then is uniformly sprayed in tree crown drip; spraying 3 ppm sodium selenite solution after applying fertilizer to the root of the waxberry tree for 3 days, wherein the application method is to spray the leaves of the waxberry tree until the leaves are wet; and carrying out normal production management, wherein the comparison is similar crown width trees of the same-age trees, and spraying clear water. The fruit can be ripe 3 days earlier, and the economic benefit is more than 2.0 times of that of the contrast.

Example 3

The red bayberry No. 1 which grows in 11 years has the crown width of 3.0 x 3.5m, 10 g of sodium selenite is applied to the rhizosphere 38d before the mature picking period, and the application method is that the sodium selenite is dissolved by clear water and then is uniformly sprayed in tree crown drip; spraying 5 ppm sodium selenite solution 2 days after rhizosphere fertilization, wherein the application method is to spray the leaves of the waxberry trees, and the leaves are wet; and carrying out normal production management, wherein the comparison is similar crown width trees of the same-age trees, and spraying clear water. The fruit can be ripe for 4 days in advance, and the economic benefit is more than 2.5 times of that of the contrast.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
