Abstract

The invention relates to a sorghum seed initiator under saline-alkali stress. By using distilled water as a carrier, the sorghum seed initiator is prepared from 5-8 ppm of SA (salicylic acid), 800-1000 ppm of PEG (polyethyleneglycol), 10-22 ppm of GA4 (gibberellin), 100-120 ppm of ethrel and 80-100 ppm of Bavistin.

Description

Sorghum seeds initator under a kind of Saline Alkali Stress

Technical field

The present invention relates to seed treatment, particularly relate to the sorghum seeds initator under a kind of Saline Alkali Stress.

Background technology

The soil salinization is the restriction plant growth, reduces a main environment factor of crop yield; China's all kinds of saline lands area amounts to approximately 100,000,000 hm ², and the annual salinization of soil and Secondary Saline constantly increase the weight of, and sustainable development of agriculture is on the hazard; Therefore, in the situation that constantly increasing, plough, increasingly reduces population, the Mechanism of Salt-tolerant of overall understanding plant, develop Salt-tolerant plant resources the agricultural seed quality is had very large impact to output and the quality of crop, particularly the seed of high vitality and vigor is that the base growth of producing the required high-quality crop in modern supermarket, grain security, ecotope etc. are significant; Chinese sorghum is one of stronger crop of salt resistance, but Chinese sorghum is very responsive to salt stress at germination period and seedling stage, salt resistance is poor, cause salt lick plantation Chinese sorghum emerge poor, planting percent is low, the difficulty of keeping a full stand of seedings, cause the disconnected ridge that is short of seedling, thereby affect later stage output, the salt resistance that how to improve Chinese sorghum seedling stage is the key issue that at first salt lick plantation Chinese sorghum should solve; This concept is proposed in 1973 by people such as Heydecker " to cause (priming) ", in order to the water absorption course of seed under description control controlled condition; Seed priming techniques is based on that the biological mechanism of seed germination proposes, purpose is to promote seed germination, and improve the coefficient of stabilization of sprout time and sprout neat rate, reduce the standard deviation of sprout time, improve seedling resistance and quality, improve nutrition condition, cause and mainly achieve the goal by osmotic adjustment, adjustment, gas regulation and hormone adjusting etc.;

Chinese sorghum, grass family, sorghum, 1 year sward is originally; Tiller or branch, the property happiness is warm, drought resisting, waterlogging; Can be divided into grain sorghum, the sugar classes such as Chinese sorghum, broom sorghum by proterties and purposes; Chinese cultivated is wider, and take the various places, northeast as maximum, grain sorghum grain is edible, wine brewing, and sugar can be refined sugar with the stalk of Chinese sorghum and starched or eat raw.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of sorghum seeds initator with anti-Saline Alkali Stress, and this seed initiator can improve germination and the uniformity of emerging, improve its emerging under Saline Alkali Stress, increases seedling dry weight, fresh weight and height of seedling.

In order to overcome the above problems the sorghum seeds initator that the invention provides under a kind of Saline Alkali Stress, each component in the sorghum seeds initator under this Saline Alkali Stress is made by following proportioning, and carrier is distilled water:

SA (salicylic acid) 5 ~ 8ppm, PGE(polyethylene glycol) 800 ~ 1000ppm, GA ₄(gibberellin) 10 ~ 22ppm, ethrel 100 ~ 120ppm, carbendazim 80 ~ 100ppm;

The invention provides the method for the sorghum seeds initator under the above-mentioned Saline Alkali Stress of preparation:

Take each raw material for standby by proportion of composing; With SA, PGE, GA ₄Dissolve in the insignificant ethanol of a small amount of weight, carbendazim dissolves in the insignificant ether of a small amount of weight; Above both mix, stirring, and the adding distil water constant volume gets seed initiator a; It is to be mixed with the solution that concentration is 100 ~ 120ppm in 4.8 ammonium sulfate and sulfuric acid mixed solution that ethrel dissolves in pH value, gets seed initiator b; Seed initiator a, b divide out preservation, mix during use;

The best optimum ratio of each component of sorghum seeds initator under this Saline Alkali Stress:

SA (salicylic acid) 6ppm, PGE(polyethylene glycol) 850ppm, GA ₄(gibberellin) 15ppm, ethrel 15ppm, carbendazim 85ppm.

Useful effect: the uniformity that the present invention can improve seed sprouting and emerge, dry weight, fresh weight and the height of seedling of increase seedling improve resistance; It utilizes the Induced by Salicylic Acid plant to improve the salt-resistance effect, makes sorghum seeds break the coercion of salinity, adds GA ₄Can activate multiple hydrolase in seed with ethrel, can also promote new enzymatic synthesis, improve the vigor of seed, shorten the seed dormancy phase, induce alpha-amylase activity to improve, promote seed sprouting; Simultaneously due to seed under the warm condition of high humidity, very easily be subject to infecting and endanger of the microorganism such as fungi, so added bactericide growing with the control pathogen; The present invention applies in practice, and more Priming Seeds can not shift to an earlier date 1 ~ 2 day and emerges, and its anti-Saline Alkali Stress effect strengthens especially.Table one is the situation of the emerging statistical form of check experiment, and table two is Seedling Quality investigation statistics tables of check experiment, and table three is statistical forms breeding time of check experiment:

The table one sorghum seeds situation statistical form of emerging

Table two sorghum seedling quality investigation statistics table (time: become seedling stage)

Table three sorghum seeds statistical form breeding time
