Fruit ripening retardant for jujube

Abstract

The invention discloses a fruit ripening retardant for jujube, and the fruit ripening retardant comprise the following raw materials in parts by weight: 0.5-0.9 part of gibberellin, 0.2-0.4 part of 6-benzyladenine, 0.7-1.0 part of rhodofix, 11-15 parts of urea, 6-10 parts of sodium borate, 3-6 parts of copper chloride, 5-8 parts of iron chloride, 6-8 parts of manganese chloride, 5-7 parts of zinc chloride, 10-15 parts of ethanol and 1000 parts of pure water. The preparation disclosed by the invention is prepared by firstly dissolving the gibberellin with the ethanol, then sequentially adding the 6-benzyladenine and the rhodofix, uniformly stirring, then completely pouring into the pure water, then adding the urea, the sodium borate, the copper chloride, the iron chloride, the manganese chloride and the zinc chloride into the pure water, fully stirring and uniformly mixing. By applying a solution of the preparation disclosed by the invention, which is diluted by 10-20 times on jujube fruits during the white-mature period, compared with a control group, the fruit ripening can be delayed by 18 days, the cracking fruit rate can be reduced by above 32%, the incidence rate of black spots is reduced by above 25%, and the content of soluble sugar of the jujube fruits and the single fruit weight can be further significantly improved.

Description

technical field [0001] The invention relates to a preparation for regulating fruit development process, in particular to a preparation capable of delaying jujube fruit ripening. 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 cultivation area has reached 1.5 million hectares, and the annual output of jujube fruit is more than 3 million tons, accounting for 1.5 million hectares of jujube trees in China. Nearly 99% of the world's jujube tree planting area, output and nearly 100% of the world's internationa...

AI Technical Summary

Problems solved by technology

There is no major breakthrough in jujube breeding technology. Among the original jujube variety resources, the quality of crack-resistant varieties is not good, and the breeding of new varieties that are resistant to fruit cracking and disease is progressing slowly; Reasonable pruning can alleviate the occurrence of fruit cracking

These measures have a certain effect in the case of low rainfall, but once the rainfall increases from late August to early and mid-September, 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 sky to harvest dates

Due to the lack of effective improvement in the prevention and control of jujube fruit cracking in the jujube industry, fruit cracking disasters have repeatedly occurred within a period of time, and jujube farmers have also become producers with high frequency of disasters and great damage
