A plant growth regulator for jujube

Abstract

The invention relates to the field of phytochemical control, in particular to a plant growth regulator for jujube. A plant growth regulator for jujube, its components include a pharmaceutical composition of titanium citrate and ethephon, supplemented by calcium acetate as a stabilizer, a specific compound of polyhexamethylene guanidine and chitosan The fungicide is used as a fungicide, wherein the pharmaceutical composition accounts for 6-10 wt% of the plant growth regulator, the stabilizer accounts for 0.7-1 wt% of the plant growth regulator, and the fungicide accounts for 0.9-1.5 wt% of the plant growth regulator. wt%, which effectively improves the stability of plant growth regulators, and is used for the growth process regulation of winter jujube, which can not only shorten the growth cycle of winter jujube, prevent fruit grains and leaves from falling off, and ageing, but also the treated winter jujube fruit is uniform in size and color. Bright, sweet and crunchy flesh, effective in preventing fruit shrinkage.

Description

technical field [0001] The invention relates to the field of phytochemical control, in particular to a plant growth regulator for winter jujube. Background technique [0002] Winter jujube, also known as Lubei winter jujube, Yanguohong, and apple jujube, is a high-quality late-maturing fresh food variety in northern Shandong. The 19 kinds of amino acids and various vitamins, trace elements such as potassium, sodium, iron, and anti-cancer substances are favored by consumers. [0003] The appearance and taste of winter jujubes from different regions are slightly different, but their growth period is roughly the same, about 120 days. The fruit is sprayed with plant growth regulators, such as ethephon, to shorten the growth cycle of winter jujube, and promote the coloration of the peel, which will be marketed earlier. [0004] However, the problem is that the use of ethephon for ripening and harvesting will cause a large amount of water loss in the winter jujube fruit before h...

AI Technical Summary

Problems solved by technology

[0004] However, there is a problem that using ethephon to accelerate ripening and harvesting will cause the winter jujube fruit to lose a lot of water before harvesting, the pulp will become soft, and the original crisp and tender texture of the winter jujube cannot be maintained, and it will not be resistant to storage after picking; in addition, ethephon will Promote the formation of plant fruit stalk and petiole detachment zone, so that the fruit grains of winter jujube will fall off, a large number of cracked and bad fruits will appear, the leaves will age and fall off, and the life cycle of winter jujube plants will be shortened
