Abstract
The invention relates to a method for promoting seeds to sprout and solves the problem that the spring drought confines the seedling establishment. The method comprises the following steps: (1) seed moisture absorption: before 1-5 days of spring planting, seeds are immersed in water, with the surface lcm below the water surface, for the moisture absorption of 19-42h under the room temperature; (2) seed drying: the saturated seeds are dried naturally to the original size. Under the condition that the soil water content is 5 percent, the seedling radicle length, the root cap length and the lateral root number of the seeds treated through the method are longer than seed seedlings which are not treated. Compared with the root total biomass of the seedlings of the seeds which are not treated, the root total biomass of the seedlings of the seeds which are treated through the method is 114.35 plus or minus 5.97a. Therefore, the seedlings of the seeds which are treated through the method can grow healthily under drought condition.
Description
Technical field
The present invention relates to a kind of method that promotes seed sprouting.
Background technology
Soil moisture is the prerequisite of budding.But temperate zone semi-arid climate district northeastward, crop-planting is accompanied by arid often and takes place.Semi-arid climate district, temperate zone, northeast, annual precipitation 300-500mm, average out to 419.8mm.Spring, soil temperature raise soon, and much wind weather has quickened soil loss of moisture speed, and the crop seed sowing is planted for hole irrigation for seeding often, but high wind and temperature rising have caused serious evaporation.Therefore, under the limited irrigation condition, the directly planting of restriction seedling of arid in spring, thereby can not reach expected yield, cause serious economic loss.For fear of the negative effect of " spring drought ", the peasant usually avoids postponing sowing date dry days, but this way can not satisfy breeding time, the especially late variety of crop.At the spring drought phenomenon, have only by cultivation step (, reducing evaporation and the raising water use efficiency) to solve arid problem as adding soil water storage.
Summary of the invention
The objective of the invention is provides a kind of method that promotes budding in order to solve the problem of spring drought restriction seedling planting.
The method that the present invention advances budding is as follows: one, seed moisture absorption: preceding 1～5 day of spring plantation is immersed in crop seed the 19h～42h that absorbs water in the water of seed 1cm that the water surface is higher than crop under the condition of room temperature; Two, seed Hui Gan: saturated crop seed natural air drying is stopped to get final product during to the seed original size.
Crop seed described in the present invention is corn seed, soya seeds, mung bean seed and sorghum seeds.
The inventive method is simple, cost is low, can be extensive use of, reduce through this method seeds treated required accumulated temperature that germinates, after planting seed can fast-germination, and seed sprouting speeds up, the regularity of emerging increases, the present invention has improved the water use efficiency of seed itself, be under 5% the condition in soil moisture content, the seedling radicle of the seed that employing the inventive method is handled is long, root cap length and lateral root number average are than the length of untreated seed seedling, adopting the seedlings root total biomass of the seed of the inventive method processing is 114.35 ± 5.97a than the root system total biomass of untreated seed seedling also, and the seedling of the seed that process the inventive method is handled can healthy growth under the condition of severe drought (soil moisture content is 5%).
