Description
Technical Field
The invention belongs to the technical field of plant growth conditioners, and particularly relates to a plant growth conditioner for relieving high-temperature damage of tobacco leaves and a using method thereof.
Background
Tobacco is one of important economic crops in China, tobacco leaves are used as raw material sources of cigarette processes, quality is always emphasized, and particularly after WTO is added, tobacco production and smoking and health problems which compete increasingly intensely internationally are raised, and higher requirements are raised for the quality of the tobacco leaves. Therefore, chinese patent document CN106927966A discloses a multi-effect tobacco leaf fertilizer, which comprises the following raw materials in parts by weight: 5-50 parts of potassium fulvate, 1-10 parts of chitosan oligosaccharide, 0.005-2 parts of brassinolide, 1-15 parts of vitamin C, 5-20 parts of monopotassium phosphate, 5-30 parts of EDTA chelated magnesium, 5-25 parts of EDTA chelated iron, 10-30 parts of boric acid, 5-25 parts of EDTA chelated zinc and 1-15 parts of ammonium molybdate. However, the multi-effect leaf fertilizer for the tobacco has a plurality of components and is complex to prepare, although the multi-effect leaf fertilizer can promote the growth of the tobacco, optimize the tissue structure of the tobacco and improve the potassium content of the tobacco, the multi-effect leaf fertilizer is not a special plant growth conditioner for overcoming the phenomenon of high-temperature induced maturity of the tobacco leaves in the south, as is well known, the quality of the tobacco leaves can be obviously reduced due to heat damage of the tobacco leaves at a temperature higher than 30 ℃ in the growth period, the temperature of the tobacco leaves in the maturation period is overhigh, chlorophyll can be damaged even at a high temperature in a short period, the photosynthesis is influenced, excessive photosynthetic products are consumed due to the enhancement of respiration, the metabolism imbalance is caused, the growth of tobacco plants is influenced, and the nicotine content can be obviously increased under the high-temperature condition, so that the quality of the tobacco leaves is reduced.
In the tobacco planting in south China, high-temperature maturity is caused due to the fact that high-temperature weather of 30 ℃ is often generated in the tobacco maturity stage of 7 and 8 months, yellowing maturity of tobacco leaves, particularly upper tobacco leaves, is seriously influenced, nicotine content of the tobacco leaves is high, fragrance is insufficient, irritation is aggravated, quality of the tobacco leaves is influenced, quality and usability of the tobacco leaves in the south are seriously influenced, and the tobacco maturity is one of main bottlenecks restricting development of raw material industry, so that the problem of high-temperature maturity in tobacco areas in the south China is urgently to be solved.
Disclosure of Invention
Therefore, the invention aims to overcome the defect that the quality of tobacco leaves is influenced by high temperature when flue-cured tobacco is planted in the south in the prior art, and provides a plant growth conditioner for reducing high-temperature damage of the tobacco leaves and a using method thereof.
In order to solve the technical problems, the invention adopts the following technical scheme:
a plant growth regulator for relieving high-temp damage to tobacco leaf is prepared from potassium sulfate, zinc sulfate, gibberellin, chitosan oligose and VC (30-70: 20-60: 0.4-1.0: 0.5-2.0: 0.5-1.5).
Preferably, the weight ratio of potassium sulfate to zinc sulfate to gibberellin to chitosan oligosaccharide to vitamin C is 50: 40: 0.6: 1: 0.8.
The application method of the plant growth conditioner comprises the following steps: weighing the components in proportion for later use, and preparing into an aqueous solution, wherein the concentration of each component in the aqueous solution is as follows: 3000 mg/L-7000 mg/L potassium sulfate, 2000 mg/L-6000 mg/L zinc sulfate, 40 mg/L-100 mg/L gibberellin, 50 mg/L-200 mg/L chitosan oligosaccharide and 50 mg/L-150 mg/L vitamin C.
Preferably, the concentration of each component in the aqueous solution is: 5000mg/L potassium sulfate, 4000mg/L zinc sulfate, 60mg/L gibberellin, 100mg/L chitosan oligosaccharide and 80mg/L vitamin C.
Furthermore, when in use, the fertilizer is sprayed on leaves, and the dosage is 35 to 50 liters per mu each time. Preferably, the spraying is carried out once in the initial picking period of the flue-cured tobacco, and the spraying is carried out once after middle leaves are picked.
The technical scheme of the invention has the following advantages:
the plant growth conditioner provided by the invention is mainly used for preventing high-temperature damage of tobacco leaves, and particularly can reduce the damage of high temperature to upper tobacco leaves. Compared with the flue-cured tobacco which is not sprayed with the plant growth conditioner, the tobacco leaves sprayed with the plant growth conditioner have the advantages of fresher color, more moderate identity, looser tissue, low nicotine content and high content of total sugar and reducing sugar, the quality of the tobacco leaf products is obviously improved, and the plant growth conditioner can meet the compatibility requirement of various cigarette factories.
