Abstract
The present invention relates to a plant growth regulator for increasing potassium content in tobacco leaves, which is characterized in that growth hormone and lanolin are uniformly mixed and prepared into a solution with a required concentration according to a certain proportion under the soil temperature equal to-20 degree, and the regulator is spread on tobacco leaves when top pruning of plant strains is carried out; additionally, tinfoil is used for covering the processing site until the harvest is over. The preparation method of the plant growth regulator of the present invention is simple, and has no need of increasing chemical fertilizers during the process of top pruning to improve the potassium content in tobacco leaves by 10 to 35.3%.
Description
The invention belongs to the plant growth regulating substance field, more particularly, is a kind of plant growth regulator and using method thereof that improves potassium content in tobacco leaf.
Potassium content is an important indicator weighing quality of tobacco.Generally require potassium content should be not less than 2% (Marchand etc., Chinese tobacco science, 18 (2): 6-11,1997).The potassium content in tobacco leaf Chang Gaoda 3.5% of developed country, and China on average is lower than 2% (Cao Zhihong, " earth and fertilising that high-quality tobacco is produced ", Jiangsu science tech publishing house, 1991).Between the past many decades, although national tobacco company and national many provinces and cities cigarette are drawn authorities and have been dropped into substantial contribution, in order to improve the research of potassium content, but work biases toward fertilizer practice, kind comparison, soil environment, weather conditions and external factor (Chen Jianjuns such as agronomy, cultivation and control measures more, the Chinese tobacco science, 20 (4): 1-4,1999; Li Folin etc., Chinese tobacco science, 20 (1): 22-25,1999), cigarette strain itself is absorbed the utilization ratio of potassium, potassium, and potassium in vivo circulation and internal potential research such as reallocation seldom, thereby the DeGrain that potassium content in tobacco leaf is improved.
Pinching in leaf tobacco production is an important regulation measure, can guarantee the yield and quality of tobacco leaf.To cause source, the original storehouse of cigarette strain relation to change but pinch, and then cause the allocation proportion of interior assimilation products of body and mineral nutrient to change.According to the data that the researcher of institute of Yunnan Tobacco section provides, after pinching, though cigarette strain amount of growth constantly increases, potassium concn descends rapidly in the tobacco leaf, even the total potassium content of cigarette strain is also on a declining curve.
The purpose of this invention is to provide a plant growth regulators, be used to improve the potassium content of tobacco leaf, thereby improve the quality of tobacco leaf.
The component that the present invention is used to improve the conditioning agent of potassium content in tobacco leaf comprises growth hormone or growth hormone and basic element of cell division mixture and lanolin, soil temperature-20 stoste, their weight ratio is 1-2: 224: 41, wherein growth hormone was 1 with the mixed weight ratio of the basic element of cell division: 0.1-1.0.
Described growth hormone comprises the auxin substance of indole-3-acetic acid, methyl, indolebutyric acid.
The described basic element of cell division comprises the cytokinin-like substance of 6-benzyladenine, furfuryl aminopurine.
The used raw material of the present invention is the commercially available prod.
The preparation method of conditioning agent of the present invention: growth hormone, lanolin, soil temperature-20 stoste are joined in the container in proportion, abundant mixing, the growth regulating agent concentration is 0.46-0.54%, puts into refrigerator and preserves down at-20 ℃.Be preferably in and use preceding preparation.
Using method of the present invention: immediately the conditioning agent for preparing is coated on the fracture of cigarette strain stem when the tobacco leaf plant is pinched, the amount of conditioning agent is the 0.5-2.0 gram, with tin platinum paper into treatment sites is encased then, until harvest home.Repeatedly result of use is better.
Advantage of the present invention and effect: the present invention strengthens the activity in plant overground part storehouse by replace the effect on original growth top after pinching with plant growth regulating substance, reaches the purpose that improves potassium content in tobacco leaf; Can be widely used in the cigarette strain of land for growing field crops plantation by field and the indoor product of the present invention that experiment showed,, preparing preparation is easy, uses when pinching.Need not increase the chemical fertilizer input can make potassium content in tobacco leaf improve 11-35.3%.The present invention obtains China national emphasis basic research development and planning project (G1990 11707) and Yunnan Province institute, the subsidy of province school collaborative project.
Below by instantiation characteristics of the present invention are described.
Example 1
Take by weighing 175mg methyl (1-naphthylacetic acid), at room temperature be dissolved in 100 ml beakers in 5 gram soil temperature-20 stostes, the dissolving back adds 27.5 gram lanolin, and fully mixing promptly obtains growth regulator of the present invention.
Example 2
Accurately take by weighing 30mg methyl and 20mg kinetin with electronic balance and be dissolved in 1 gram soil temperature-20 stoste, the dissolving back adds 5.5 gram lanolin, and fully mixing gets final product.
Example 3
Normal for the growth regulator product raising potassium content in tobacco leaf test of using example 1 under the potassium condition.
Cultivate the cigarette seedling by the sand culture method in the laboratory, used kind is K326.Use up pancebrin and water the cigarette strain every day.Grow to the prosperous back+conditioning agent of pinching respectively and pinch when long-term in the cigarette strain and handle (after pinching 1 gram conditioning agent is coated on the fracture of cigarette strain stem, with tin platinum paper into treatment sites is encased) until harvest home.Stay 9 blades after pinching, divide upper, middle and lower three parts, each is handled and repeats 7 times.Before handling, gather in the crops blade after 8 days respectively with processing.
The results rear blade completed 30 minutes through 105 ℃ in baking oven, and 70 ℃ dry to constant weight.Sample is used the flame spectrophotometer measuring potassium content after conventional method ashing.Only 8 days, shine raising 8%-12% with the comparison of the different parts potassium content in tobacco leaf after the product treatment of example 1.The results are shown in following table:
The back growth regulator of pinching under the sand culture condition is handled the influence to potassium content in tobacco leaf in 8 days
| Handle | Potassium content in tobacco leaf (K%) | ||
| Upper leaf | Middle leaf | The bottom leaf | |
