Abstract
The invention discloses a preparation for improving the seedling emergence quality of sweet sorghum in saline-alkali soil, and relates to the technical field of agricultural production. The preparation is composed of a sweet sorghum seed soaking agent and a sweet sorghum seedling spray, and concretely comprises betaine, propionyl brassinolide, ascorbic acid, potassium dihydrogen phosphate, vitamin B1, zinc lignin carbonate, manganese sulfate, magnesium sulfate, mycose, boric acid, and the balance of clear water. Seeds are soaked in the sweet sorghum seed soaking agent before sowing, the soaked seeds are aired at room temperature, the aired seeds are sowed, and foliar spraying of the sweet sorghum seedling spray is carried out twice in the trefoil stage of seedlings. A method for regulating the phytohormone physiology and exogenously supplementing mineral nutrients is adopted to enhance the salt resistance of saline-alkali soil sweet sorghum seedlings, promote seedling emergence, protection and growth of saline-alkali soil sweet sorghum and improve the biological output of sweet sorghum stems and the output of the sweet sorghum grains.
Description
Technical field
The present invention relates to field of agricultural production technologies, be specifically related to a kind ofly improve beach saline-alkali ground sweet sorghum and to emerge the preparation of quality and using method.
Background technology
The soil salinization in the whole world nearly 20%, the salinity of soil middle and high concentration causes osmotic stress to crop and ionic stress is poisoned, thus affects the growth of crop, causes crop yield to decline, develops the world-famous puzzle that saltings becomes agriculture production.About there are 2,700 ten thousand hm in NORTHWEST CHINA inland and Coastal beach area
2above salinized soil and secondary salinization of land, become the important restriction factor of China's agricultural sustainable development.Sweet sorghum is Gramineae sorghum annual herb plant, is a kind of drought-enduring waterlogging-resistant, impoverishment tolerant, Salt And Alkali Tolerance, the high-density energy-source plant of resistance and high-yielding.Sweet sorghum cauline leaf and seed are all excellent feeds, and nutritive value is higher.Plant sweet sorghum in saltings and not only can improve land utilization ratio, alleviate the anxiety of cultivated land resource, and saline-alkali soil physicochemical structure can be improved, be conducive to varieties in saline-alkali areas Improvement of Ecological Environment.
Coastal beach is distributed with a large amount of salinization soils, and spring arid is short of rain, and soil fertility is poor, serious to agriculture production harm.Sweet sorghum seed germinate and seedling stage more responsive to Salt Strees Condition, salt stress can cause seeding ratio to reduce, death of seedling rate reduction, plant growth and development is suppressed.Therefore, ensure that the growth of sweet sorghum germination and emergence is the key of development coastal tidal saltings sweet sorghum production.
For ensureing that saltings sweet sorghum germination and emergence normally effectively grows, one is the saltiness being reduced soil by rational soil and water management and chemical amelioration measure, as " a kind of improve saltings plant sweet sorghum the method for quality of emerging " that publication number is CN102668847A, but this method cost is high, investment large, waste time and energy, two is by Chemical treatment seed or seedling, improves sweet sorghum saline-alkaline tolerance, cost is low, and practicality simple to operate.As " the sorghum seeds initiator under a kind of Saline Alkali Stress " that publication number is CN103109847A, but the main component of this initiator is Plant hormones regulators,gibberellins, Whitfield's ointment, polyoxyethylene glycol, and technology provide only the method improving seeding ratio under Saline Alkali Stress, to seedling grow and seedling protecting effect is not yet mentioned.
Summary of the invention
The object of the invention is to emerge for beach saline-alkali ground sweet sorghum seed, the problem of seedling difficulty, and the shortcoming and defect of existing sweet sorghum initiator, provides a kind of and improves saltings sweet sorghum and to emerge the preparation of quality.Said preparation is by using plant growth regulating substance and mineral nutrient element collocation, while raising saltings sweet sorghum germination and emergence, seedling salt resistance ability, also for its physiological metabolism provides required nutritive substance, promote that it grows safely and effectively under saline-alkali environment.
In order to solve the problem existing for background technology, the technical solution used in the present invention is:
A kind ofly improve saltings sweet sorghum and to emerge the preparation of quality, it is made up of sweet sorghum seed soaking agent and sweet sorghum seedling spray, described sweet sorghum seed soaking agent, be made up of the component of following weight percent: trimethyl-glycine 0.25% ~ 0.5%, propionylbrassinolide 0.0002% ~ 0.00005%, xitix 0.003 ~ 0.006%, potassium primary phosphate 0.5% ~ 1%, vitamins B
