Abstract
The invention discloses a method for cold resistance treatment on corn seeds to eliminate rogues, aiming at solving the problems that corn seeds treated by using a conventional method are easy to powder, the seeding temperature needs to be high, the sprouting rate and the effective strong seedling rate are low and the corn yield after autumn is low. The method comprises the following steps: I, finely selecting corn seeds; II, performing plasma treatment; III, soaking the seeds; IV, accelerating germination; V, selecting seeds; VI, drying the seeds; and VII, storing the seeds, thereby completing the method for cold resistance treatment on corn seeds to eliminate rogues. The method has the advantages that the seeding time of the corn seeds treated by using the method is earlier for 10-15 days compared with that of ordinary corn seeds, and the seeds are not powdered; 100% of seeds with strong sprouts can be sown, the effective strong seedling rate is up to 100%, the corn seedlings are strong and in good growth vigor, and the corn yield after autumn is increased by 15%. The invention provides the method for cold resistance treatment on corn seeds to eliminate rogues.
Description
Technical field
The present invention relates to the method for the cold-resistant and superseded inferior strain of a kind of corn seed.
Background technology
Ordinary maize seed is when planting, directly sow after seed is only the used Normal seed coating dressing such as " many grams of good fortune ", " sharp victory ", its shortcoming is that soil temperature must reach more than 8 DEG C and sows guarantee not by chilling injury, otherwise sowing too early, running into low temperature and high relative humidity soil will powder kind, i.e. rotten kind; Its two, conventional seed, without " method of cold-resistant and superseded inferior strain " process, directly after planting, can not ensure 100% bud rate, with can not ensureing under the seed that 98% bud gesture is strong.Effective strong sprout only has 80%, and weak seedling has become weeds, can not meet the planting requirement of modern high yield agronomy.
Summary of the invention
The object of the invention is to solve existing method process corn seed and there is easy powder kind, need the temperature of sowing high, germination rate and all low and that corn yield the is low after autumn problem of effective rate in strong sprout, and provide the cold-resistant process of a kind of corn seed to eliminate the method for inferior strain.
A method for inferior strain is eliminated in the cold-resistant process of corn seed, specifically completes according to the following steps:
One, elite corn seed: use the square hole screen that fineness is 5.0mm to sieve to corn seed, remove the corn seed of small-size maize seed and broken wound, obtain selected corn seed;
Two, plasma treatment: be under the condition of 1.0A in current intensity, uses plasma seed processing machine to process twice continuously to selected corn seed; Obtain the corn seed after plasma treatment;
Three, soak seed: in the environment at room temperature dry by the corn seed after plasma treatment, preserve 120h ~ 168h, then to be immersed in temperature be 16h ~ 18h in the brassin liquid of 20 DEG C ~ 25 DEG C, obtain brassin liquid soak after corn seed;
Four, vernalization is sprouted: the corn seed after brassin liquid soaks is put into germination cylinder, in temperature be under the condition of 20 DEG C ~ 30 DEG C every 3h ~ 4h by germination drum turning 720 °, every 6h ~ 7h, serviceability temperature is corn seed after the distilled water cleaning brassin liquid of 25 DEG C ~ 30 DEG C soaks 1 time, until the germination rate of corn seed reaches 80% ~ 85%, stop germinate, obtain vernalization sprout after corn seed;
Five, pick out seed: pick out at ambient temperature vernalization sprout after corn seed in the corn seed that do not sprout and the weak corn seed of bud gesture, obtain the corn seed that bud gesture is strong; The corn seed using sharp victory seed coat agent strong to bud gesture carries out dressing, obtains the corn seed after sharp victory seed coat agent dressing;
The mass ratio of the corn seed that the volume of described sharp victory seed coat agent and bud gesture are strengthened is 50 kilograms: (200mL ~ 300mL);
Six, roasted grain: the moisture using seed dryer the corn seed after sharp victory seed coat agent dressing to be carried out to the corn seed of drying to sharp victory seed coat agent dressing is 20% ~ 22%, stops drying, and obtains the corn seed after drying;
Seven, stored seed: it is that the dry warehouse of 5 DEG C ~ 20 DEG C is preserved that the corn seed after drying is put into temperature, namely completes the method that inferior strain is eliminated in the cold-resistant process of a kind of corn seed.
Advantage of the present invention:
One, the corn seed after process of the present invention, is advanced by 10 days ~ 15 days between the sowing than ordinary maize seed, the corn seed after process of the present invention can be 4.5 DEG C of sowings in outdoor ground temperature, and not powder kind;
Two, the present invention has eliminated the weak corn seed of bud gesture, with ensure that under the seed that 100% bud gesture is strong, after planting there is not weak seedling, effective strong sprout reaches 100%, and maize seedling is strengthened, growing way is good, and compared with the corn seed do not used after process of the present invention, corn yield after autumn adds 15%;
Three, the corn seed of use process of the present invention can than shifting to an earlier date sowing in 10 days ~ 15 days normal sowing time, namely farming season is robbed, can emerge ahead of time again 7 days ~ 10 days, reseize effective accumulated temperature 150 DEG C ~ 200 DEG C, effectively can eliminate ablastous seed and the weak seed of bud gesture by the corn seed of process of the present invention, reduce weak seedling rate.
The present invention can obtain the method that inferior strain is eliminated in the cold-resistant process of a kind of corn seed.
