Abstract

The invention relates to a maize seed initiator under salt stress. By using distilled water as a carrier, the maize seed initiator is prepared from 5-7 ppm of SA (salicylic acid), 500-600 ppm of KNO3, 500-600 ppm of K2HPO4, 20-32 ppm of GA4 (gibberellin), 80-120 ppm of ethrel and 100-120 ppm of Bavistin.

Description

Corn seed initator under a kind of salt adverse circumstance

Technical field

The present invention relates to seed treatment, particularly relate to the corn seed initator under a kind of salt adverse circumstance.

Background technology

The soil salinization is 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 the sustainable development of agricultural production is on the hazard; Therefore, constantly increase, plough at population in the situation that of increasingly minimizing, the Mechanism of Salt-tolerant of overall understanding plant, the output on crop and quality have very large impact on agricultural seed quality to develop Salt-tolerant plant resources, and 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; Corn is the seed of the beautiful sorghum broomcorn millet of gramineous herbaceous plant, is important cereal crops, and in China, its cultivated area is only second to paddy rice, wheat, occupies the 3rd, but Maize Production compares with other cereal productions, and input cost is higher, and output benefit is on the low side; Salt stress affects the growth of emergence of corn and plant, causes the corn underproduction, how to improve the salt resistance of Maize at Seedling Stage, is the key of salt-affected soil maize planting; This concept is proposed in 1973 by people such as Heydecker " to cause (priming) ", in order to describe the water absorption course of controlling seed under controlled condition; Seed priming techniques is that the biological mechanism based on seed germination proposes, object 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 mainly achieve the goal by osmotic adjustment, temperature adjusting, gas regulation and hormone adjusting etc.

Summary of the invention

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

In order to overcome the above problems the corn seed initator the invention provides under a kind of salt adverse circumstance, the each component in the corn seed initator under this salt adverse circumstance is made according to the following ratio, and carrier is distilled water:

SA (salicylic acid) 5 ~ 7ppm, KNO ₃500 ~ 600ppm, K ₂hPO ₄500 ~ 600ppm, GA ₄(gibberellin) 20 ~ 32ppm, ethrel 80 ~ 120ppm, carbendazim 100 ~ 120ppm;

The invention provides the method for the corn seed initator under the above-mentioned salt adverse circumstance of preparation:

Take each raw material for standby by proportion of composing; By SA, GA ₄dissolve in the insignificant ethanol of a small amount of weight, carbendazim dissolves in the insignificant ether of a small amount of weight, KNO ₃, K ₂hPO ₄dissolve in distilled water; Above three mixes, stirs, and adding distil water constant volume obtains seed initiator a; It is to be mixed with the solution that concentration is 80 ~ 120ppm in 4.8 ammonium sulfate and sulfuric acid mixed solution that ethrel dissolves in pH value, obtains seed initiator b; Seed initiator a, b divide out preservation, when use, mix;

The best optimum ratio of the each component of corn seed initator under this salt adverse circumstance:

SA (salicylic acid) 6ppm, KNO ₃540ppm, K ₂hPO ₄560ppm, GA ₄(gibberellin) 26ppm, ethrel 100ppm, carbendazim 110ppm.

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 Induced by Salicylic Acid plant to improve salt-resistance effect, makes corn seed break the coercion of salinity, adds GA ₄can activate the multiple hydrolase in seed with ethrel, can also promote new enzymatic synthesis, improve the vigor of seed, shorten the seed dormancy phase, induction alpha-amylase activity improves, and promotes seed sprouting; Simultaneously, because seed is under the warm condition of high humidity, be very easily subject to infecting and endanger of the microorganisms such as fungi, so added bactericide growing with control pathogen; The present invention applies in practice, and more Priming Seeds can not shift to an earlier date 2 ~ 3 days 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 corn seed situation statistical form (18 DEG C of temperature) of emerging

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

Table three corn seed statistical form breeding time
