Abstract
A method for treating corn seeds in order to promote early maturity includes such steps as immersing in warm water, promoting growth of root, low-temp suppression to growth, strong sunning for breaking root, and repeating said steps again.
Description
Technical field
The invention belongs to crop seeds processing and handle agronomic technique, relate generally to the processing method of early maturing of corn seed.
Background technology
Corn is the very big a kind of agricultural crops of China and even countries in the world cultivated area, is one of important source of human grain ration and animal feed and the raw material of industry, and because of its purposes and use value widely, the various countries agriculturist is paying close attention to corn with high yield research.At present, in different accumulated temperature regions, different corn varieties is arranged, the long-living long-term corn variety of the high area of accumulated temperature plantation mostly is quality better, kind that output is high, this veriety can not be planted in the area that accumulated temperature is low, otherwise remaining green when it is due to become yellow and ripe, the jejune phenomenon of seed can take place, can only plant weak point in vegetative period, inferior quality, corn variety that output is lower.It is precocious that quality better, long-living long-term corn that output is high are promoted in process of growth, make it can satisfy accumulated temperature low area plantation needs, enlarge the high-yield corn planting range, increase considerably corn crop yield per unit area, improving the corn quality is the extremely urgent technical issues that need to address of current agriculturist.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned plant in high accumulated temperature district long-living long-term, quality better, the corn variety that output is high is not suitable for the technical problem of planting in the accumulated temperature low area, a kind of corn seed processing method that promotes early maturing of corn of research invention, by corn seed is passed through twice vernalization successively before plantation is used, illumination, the processing of being completely cured, make such seed shift to an earlier date about ten days maturations than former undressed similar seed plant in the cycle at its plant strain growth, keeping former corn variety quality, on the high yield basis, reach the promotion early maturing of corn, enlarge high yield and high quality maize planting zone, increase the purpose of corn yield.
The object of the present invention is achieved like this, and a kind of to impel the corn seed processing method of early maturing of corn be that corn seed is adopted forward and backward twice vernalization, illumination, the processing of being completely cured, and its techniqueflow is as follows:
1., vernalization, illumination for the first time, be completely cured: earlier pending original corn seed is screened; To screen the qualified corn seed in back then and in container, steep 8-10 hour, often stir the corn seed in the container simultaneously, and keep the seed temperature even with the water logging of 42-48 ℃ of temperature; Pulling corn seed after the immersion out packs in the ventilative bag, whole bag leaves in the 18-20 ℃ of environment urges the root operation, when the length of corn seed root during at the 2-3 millimeter, the low temperature vernalization in temperature is 4-7 ℃ of environment of corn seed dispenser, suppress root growth after 3-5 days, seed is taken out exposed natural lighting in the sun be exposed to the sun 3-5 days, when the seed moisture proportion that is exposed to the sun when illumination reaches original corn seed moisture content, finish the operation of being completely cured;
2., vernalization, illumination for the second time, be completely cured: with above-mentioned through the vernalization first time, illumination, be completely cured corn seed after handling in container with 35 ℃-40 ℃ water logging bubble 7-9 hour, often stir the corn seed in the container simultaneously, maintenance seed temperature is even; Pulling corn seed after the immersion out packs in the ventilative bag, whole bag leaves in the 16-18 ℃ of environment urges the root operation, when the length of corn seed root during at the 2-3 millimeter, the low temperature vernalization in temperature is 4-7 ℃ of environment of corn seed dispenser, suppress root growth after 3-5 days, seed is taken out exposed illumination in the sun, be exposed to the sun naturally 3-5 days, when making the corn seed moisture content roll back original corn seed moisture content, promptly finish the processing of early ripening maize seed.
The present invention makes corn seed prior to seeding through after twice vernalization, illumination, the technical finesse of being completely cured, the enzyme of corn seed and hormone are pulled the trigger, increased activity, embryo generation acute variation, impel the fate of early maturing of corn in embryo, promptly to finish prior to seeding, have the advantages that the corn seed processing method is simple, with low cost, enlarge high yield and high quality maize planting zone, raising corn crop output, assurance corn quality.
Embodiment
Below embodiment of the present invention is described in detail for example.Earlier pending original corn seed is screened, remove arabica and underproof kind grain, to screen qualified corn seed then and with temperature be 45 ℃ water logging bubble 9 hours in container, must often stir the corn seed in the container during immersion, make its temperature even, help the unanimity that the corn seed root goes out, pulling corn seed after the immersion out packs in the ventilative bag, urge the root operation in the environment that whole bag leaves in about 19 ℃, when the root of corn seed all sprouts and long during to length 2-3 millimeter, the low temperature vernalization in temperature is 5 ℃ or 6 ℃ of environment of corn seed dispenser, suppress root growth after 4 days, again seed is taken out exposed natural lighting in the sun and be exposed to the sun about 4 days, when seed moisture proportion reaches original corn seed moisture content, promptly finish the vernalization first time of corn seed, illumination, the processing of being completely cured; In container, use the water logging of 38 ℃ of temperature to steep once more 8 hours the corn seed after the above-mentioned processing, often stir simultaneously the corn seed in the container, keep the seed temperature even, pulling corn seed after the immersion out packs in the ventilative bag, whole bag places 17 ℃ of left and right sides environment to urge the root operation, when the root of corn seed all sprouts and long during to length 2-3 millimeter, once more the low temperature vernalization in temperature is the environment of 5 ℃ or 6 ℃ of corn seed dispenser, suppress root growth after 4 days, seed is taken out exposed illumination in the sun, naturally be exposed to the sun about 4 days, when seed moisture proportion is reduced to the primordial seed moisture content once more, finish vernalization for the second time, illumination, the processing of being completely cured obtains the early ripening maize seed, finishes the processing of early ripening maize seed.
In production test, when the corn seed of this method processing is taken root in soil, be taking root for the third time of this seed, its root system is very flourishing, moisture content and nutrient absorption when helping plant growth, and the plant lodging tolerance is strong, help and promoted the maturation early of corn crop, test shows, compares with former corn seed through the corn seed that this method is handled, and its maturing stage can shorten about 10 days.
