Chinese date fruit maturation promoter

Abstract

The invention discloses a Chinese date fruit maturation promoter. The promoter consists of the following raw materials in parts by mass: 5 to 6 parts of paclobutrazol, 7 to 9 parts of sodium borate, 2 to 5 parts of copper chloride, 5 to 8 parts of iron chloride, 4 to 8 parts of manganese chloride, 3 to 5 parts of zinc chloride and 1,000 parts of purified water. 10-time diluent of the promoter is sprayed onto fruits during a Chinese date fruit expansion period, after being sprayed for two times, the fruits are completely colored 20 days later, the maturing time of the fruits can be over 15 days earlier than that of a reference group, the fruit cracking rate is reduced by over 35 percent, the incidence rate of black spot is reduced by over 20 percent, and Vc, dissoluble sugar content and single fruit weight in the fruits are not obviously different from those in the reference group. The preparation is simple in the preparation method and the using method, Chinese date farmers can prepare the preparation, and the promoter is convenient to popularize and obvious in economic benefit.

Description

technical field [0001] The invention relates to a preparation for regulating fruit development process, in particular to a compound preparation for promoting early ripening of jujube fruit. Background technique [0002] Jujube has high nutritional value. In the 1990s, jujube trees have gradually evolved from sporadic and intercropping cultivation to a horticultural intensive cultivation model. The area of ​​jujube trees has expanded rapidly, and the yield per unit area has increased significantly. The "China Jujube Industry Development Report (1949-2007)" published by the State Forestry Administration and the National Jujube Industry Development Cooperation Group in 2010 pointed out that the national jujube planting area has reached 1.5 million hectares, and the annual output of jujube fruit is more than 3 million tons, accounting for the Nearly 99% of the world's jujube tree planting area, output and nearly 100% of the world's international trade, with an annual output val...

AI Technical Summary

Problems solved by technology

[0003] Since the 21st century, due to global climate change, the rainy season in the main jujube producing areas has been postponed to late August to early September, which coincides with the ripening period to the coloring period of jujube fruit development, resulting in large-scale and large-scale fruit cracking. Jujube orchard management Significant decline in benefits

These measures have a certain effect in the case of low rainfall, but once the rainfall increases in the later stage of fruit development, the duration will become longer, the control effect will be poor, and the loss is still difficult to control. At present, 80% of jujube farmers still rely on the weather. Harvest dates

Due to the fact that the prevention and control technology of jujube fruit cracking in the jujube industry has not been effectively improved, fruit cracking disasters have repeatedly occurred for a period of time, and jujube farmers have also become producers with high frequency of disasters and great damage
