Yellow accelerating agent of cured tobacco leaf

Abstract

The invention discloses a cured tobacco leaf luteinizing agent, which is prepared from the following raw materials by weight proportion: 0.02-5 parts of sodium bicarbonate, 0.02-5 of potassium primary phosphate, 0.1-1.1 parts of calcium chloride and 0.0001-0.005 part of jasmonic. When the tobacco leaf is in physiological maturity, the cured tobacco leaf luteinizing agent is sprayed on the leaf surface for once or twice based on the condition of the tobacco leaf; after three to seven days of treatment, the tobacco leaf can be luteinized obviously. Compared with the control group, the luteinized leaf can lead to an increase of economic benefit by over 30%, with the quality improving to a certain extent. Meanwhile, the invention has the advantages of low cost and convenient use.

Description

technical field [0001] The invention belongs to plant growth regulators, in particular to a yellowing agent for flue-cured tobacco leaves. Background technique [0002] In the process of tobacco leaf production, it is required that the tobacco leaves should be yellowed in time during the mature stage, fully yellowed and matured, so as to obtain the greatest economic benefits by producing high-grade or special-grade orange or lemon-colored tobacco leaves with good color and good internal quality, but the fact is that In general, it is often caused by excessive fertilization in the tobacco field or continuous cloudy and rainy periods during the maturity period, or a sharp drop in temperature during the maturity period, which causes the tobacco leaves to reach normal maturity, but the leaf color is still dark green and it is too late to fall yellow, so it cannot be baked. A large amount of tobacco leaves have to be discarded, causing significant economic losses. Contents o...

[0002] During the production process of tobacco leaves, it is required that the tobacco leaves should turn yellow in time during the mature stage, fully turn yellow and mature, so as to produce high-grade or special-grade tobacco leaves with good color and good internal quality. orange or lemon-colored tobacco leaves to obtain the greatest economic benefits, but in fact, often due to excessive fertilization in the tobacco field or continuous cloudy and rainy periods during the maturity period, or a sharp drop in temperature during the maturity period, the tobacco leaves reach normal maturity and the leaf color remains unchanged. It is dark green and it is too late to turn yellow, so it cannot be baked

A large amount of tobacco leaves have to be discarded, causing significant economic losses
