Problems solved by technology

This method has a good effect on relieving the deformity of flue-cured tobacco caused by quinclorac. However, the synthetic plant growth regulator has no affinity with crops, and the dosage is difficult to control. Excessive dosage will aggravate the distortion symptoms of tobacco leaves.
And there is no report on the preparation and application method of flue-cured tobacco deformities caused by quinclorac by utilizing natural plant growth regulators etc.

Embodiment 1

[0012] The weight percent content of each component of the quinclorac-induced flue-cured tobacco deformity release agent is respectively: 0.6% of Bihu, 5.6% of Yiwei powder, 18.8% of potassium nitrate, and 75.0% of brewed vinegar. The release agent of flue-cured tobacco deformity caused by quinclorac is formulated according to the above component weight percentage content, and at the early stage of flue-cured tobacco deformity caused by quinclorac (about the 30th day after transplanting), every 1000 tobacco plants use this release agent 533g , after diluting 56 times with water, evenly spray the tobacco plants and the front and back of the tobacco leaves, subject to the fact that the leaf surface is wet and does not drip. Result of the test (table 1) shows, application release agent provided by the present invention, quinclorac causes the leaf length of flue-cured tobacco abnormality tobacco leaf to significantly increase, leaf width and total sugar extremely significantly incr...

Embodiment 2

[0014] The weight percent content of each component of the quinclorac-induced flue-cured tobacco deformity release agent is respectively: 0.4% of Bihu, 5.8% of Yiwei powder, 21.6% of potassium nitrate, and 72.2% of brewed vinegar. The release agent of quinclorac-induced flue-cured tobacco deformity is formulated according to the above component weight percentage content, and at the initial stage of flue-cured tobacco deformity caused by quinclorac (about the 30th day after transplanting), every 1000 tobacco plants use this release agent 693g , after diluting 43 times with water, evenly spray the tobacco plants and the front and back of the tobacco leaves, subject to the fact that the leaf surface is wet and not dripping. Result of the test (table 1) shows, application release agent provided by the present invention, quinclorac causes the leaf length of flue-cured tobacco abnormality tobacco leaf to significantly increase, leaf width and total sugar extremely significantly incre...

Embodiment 3

[0016] The weight percent content of each component of the quinclorac-induced flue-cured tobacco deformity release agent is respectively: 0.4% of Bihu, 5.9% of Yiwei powder, 23.4% of potassium nitrate, and 70.3% of brewed vinegar. The release agent of flue-cured tobacco deformity caused by quinclorac is formulated according to the above component weight percentage content, and at the initial stage of flue-cured tobacco deformity caused by quinclorac (about the 30th day after transplanting), every 1000 tobacco plants use this release agent 853g , after diluting 35 times with water, spray the tobacco plants and the front and back of the tobacco leaves evenly, subject to the fact that the leaf surface is wet and not dripping. Result of the test (table 1) shows, application release agent provided by the present invention, quinclorac causes the leaf length of flue-cured tobacco abnormality tobacco leaf to significantly increase, leaf width and total sugar extremely significantly inc...

Abstract

The invention relates to a detoxicating agent on tobacco deformity induced by quinclorac and an applying method thereof. The detoxicating agent is prepared from the following materials: 0.4%-0.6% of natural plant growth regulator, 3.6%-9.0% of plant microecology agent, 13.3%-31.6% of tobacco leaf nutrient and 61.3%-81.9% of efficiency enhancer. The applying method of the detoxicating agent comprises the following steps of: using 35-75 times of clean water to dilute 500g-900g of detoxicating agent for every 1000 tobacco plants, and uniformly spraying onto the tobacco plants and the positive and reverse surfaces of the tobacco leaves until the wet dew on the leaf surface has no water dripping in the early generation period of tobacco deformity induced by quinclorac. The invention obviously increases the leaf length of the tobacco leaf deformity induced by quinclorac, obviously increases the leaf width and total sugar, obviously decreases the nicotine, effectively removes the symptom of the tobacco leaf deformity induced by quinclorac, enables the tobaccom leaf to obviously recover the normal botany property and internal chemical quality, and has the advantages of strong compounding property of raw materials, simple preparation, high safety, strong point and high practical value in the tobacco leaf production.

Description

technical field [0001] The invention relates to a release agent for tobacco deformities caused by herbicides and an application thereof, in particular to a release agent for flue-cured tobacco deformities induced by quinclorac and an application method thereof. Background technique [0002] The chemical name of quinclorac is 3,7-dichloro-8-quinoline carboxylic acid. It is a selective pre-emergence and post-emergence herbicide developed by BASF in Germany. It is mainly used to control barnyardgrass and other grasses in rice fields. Weeds have the advantages of wide application period, low dosage and good weeding effect. At present, this product has been registered on rice in my country. There are more than 150 products of quinclorac or its compound preparations in China. It has become the most widely used herbicide product in rice fields today. [0003] Due to the long residual effect period of the quinclorac herbicide, the time interval between the crops after planting is str...
