Abstract
A salt-resistant preparation for improving the salt resistance of the wheat and an application method thereof belong to the technical field of improving the salt resistance of the wheat to increase the wheat production. The method comprises the following steps: 1) soaking in the salt resistance preparation, wherein, with the overall weight being 1kg , the final composite ingredients are 3-4g of Ca (NO3)2, 1.2-1.5g of KH2PO4, 1.5-2g of KI, 0.35g of MnSO4, 10mg of Na2SeO3, 40-60mg of cytokinin, and water in balancing amount; 2) spraying the salt resistant preparation on the surfaces of leaves, wherein, with the overall weight being 1kg, the final composite ingredients are 1-1.2g of Ca (NO3)2, 0.25-0.3g of KH2PO4, 0.35g of KI, 0.1g of MnSO4, 2mg of Na2SeO3, 2-10mg of cytokinin, and water in balancing amount. Wheat seeds are soaked in the salt resistant preparation for one time before being planted, and the salt resistant preparation is sprayed on the surfaces of the leaves after the fifteen days of wheat seedlings turn green in the spring of the next year. The invention has the advantages of significantly improving the ratio of emergence of wheat seeds under high salinity, promoting the growing development of wheat plants, increasing the production of the wheat by 15-20 percent, and being suitable for the soil with salt contents being 0.3 percent.
Description
Technical field
The present invention relates to improve the wheat salt-resistance to improve the technical field of wheat yield, the particularly a kind of anti-salt pref of wheat salt-resistance and application method of this anti-salt pref of improving.
Technical background
Making full use of of salinization soil is to promote agro based economic development, the important channel of improving agroecological environment.There are salination and secondary salinization soil in China more than 4,000 ten thousand hectares, accounts for about 1/10 of China arable land.Large-area salination soil has had a strong impact on grain yield, has become a very important limiting factor of China's agricultural production.Along with the increase of population and the minimizing of arable area, to the year two thousand thirty China's total output of grain only reach hundred million tons of 6.4-7, promptly grain yield must could satisfy the grain demand of China substantially improving more than 50% on the level at present.Thereby in today that freshwater resources worsening shortages, land area reduce gradually, development and use salination soil has become a present important research target, has become the key subjects that press for solution now.
To studies show that of plant anti-salt mechanism: soil salt too much can suppress plant growing, reduces crop yield.Salinity too much produces the main cause that injures to plant two aspects: the one, and ion is poisoned and nutritional deficiency; The 2nd, physiological drought.This two aspect is all relevant with the integrality of too much salt ion destruction cell membrane.Can make the plant salt evil be able to part by rational soil and water management and chemical modifying measure and alleviate, but cost is too high; Though the breeding scholar is by cultivating and screening salt tolerant crop kind, obtained certain achievement, utilize a kind of new foreign DNA to import means as Chinese patent CN1230593 is disclosed, improve the salt-resistance of recipient plant, but see still not very good from present present situation.Wheat is the second largest cereal crops of China, and salinity is coerced the comparison sensitivity.Because its vegetative period is long, the autumn that arid just short of rain, soil transpiration rate of winter wheat sowing phase is big, the soil salinization rises, and the seedling fast growing period accumulation of salt in the surface soil serious spring just, therefore, from regulation and control plant physiology active mechanism angle, the saline-alkaline tolerance that utilizes the chemical control means to improve wheat is one of important channel of improving wheat yield.
Summary of the invention
The purpose of this invention is to provide a kind of anti-salt pref that improves the wheat salt-resistance, this anti-salt pref can improve the tolerance of wheat to salinity effectively, wheat can be grown in the soil of salt content 0.3% and obtains higher output.
The present invention also provides the application method of this anti-salt pref.
The technical scheme that technical solution problem of the present invention is taked is:
A kind of anti-salt pref that improves the wheat salt-resistance is characterized in that, soaks anti-salt pref and wheat seedling phase foliage-spray is formed with anti-salt pref by seed before the wheat cultivation, seed soaks anti-salt pref before the described wheat cultivation, in the gross weight is 1kg, and its composition finally is Ca (NO

The described basic element of cell division is the 6-benzylaminopurine.
The described basic element of cell division is a zeatin, chemical name: 6-is trans-and 4-hydroxy-3-methyl-but-2-ene base aminopurine.
The described basic element of cell division is a 6-furfuryl group aminopurine.
Anti-salt pref can be stored with 100 times of concentrates, directly is made into 100 times of solution during formulated product, and the time spent is diluted to ultimate density again.Also can be directly with solid form preparation and storage, the time spent is diluted to ultimate density again.
The application method that improves the anti-salt pref of wheat salt-resistance is:
Soak 1 time before the sowing, before soaking seed before the wheat cultivation being soaked anti-salt pref adds clear water and is diluted to ultimate density, wheat seed with election contest soaked 5-6 hour in anti-salt pref then, and seed soaks anti-salt pref by the anti-salt pref input of every 4000ml 10kg wheat seed before wheat seed and the wheat cultivation; At room temperature dry after the immersion to being fit to sowing humidity and get final product, preserve as the need long period, seed should dry to moisture below 14%, and in preservation below 15 ℃;
Wheat seedling phase foliage-spray is used: spring in next year, wheat seedling began foliage-spray 2-3 time after turning green 15 days, each 15-20 days at interval; Before spraying, the anti-salt pref of wheat seedling phase foliage-spray is diluted to ultimate density with clear water by a certain percentage, the amount of spraying is at every mu of 12.5L; The time of spraying should be selected at dusk, helps preparation and fully absorbs.
