Abstract
The invention discloses a method for improving the old seed vitality of hybrid rice and hybrid corn. In the method, a conditioning agent is adopted to soak hybrid rice old seeds or hybrid corn old seeds, wherein the conditioning agent is aqueous solution which has a mass concentration of 50 percent and consists of sodium naphthenate and zinc sulfate; in the process of soaking the hybrid rice old seeds, the content of the sodium naphthenate in the conditioning agent is 0.7 ml/l, the mass content of the zinc sulfate is 0.4 to 0.8 percent, and the soaking time is 16 hours; and in the process soaking the hybrid corn old seeds, the content of the sodium naphthenate in the conditioning agent is 0.2 ml/l, the mass content of the zinc sulfate is 0.2 to 0.4 percent, and the soaking time is 16 hours. According to the method, the germination vigor, the germination rate and the seedling quality of the two hybrid old seeds can be improved, and a foundation for improving the yield of the hybrid rice and the hybrid corn productions is laid.
Description
Technical field
The present invention relates to a kind of method that improves hybrid rice and the old seed vitality of hybrid maize, particularly relate to the two assorted old seeds of a kind of employing sodium naphthenate and zinc sulphate associated treatment to improve old seed vitality.
Background technology
Two hybrid are meant hybrid rice and hybrid maize.In agricultural production, more or less utilize the old seed of crop of some.What is meant by old seed, the seed that will preserve usually more than 1 year is referred to as old seed.The utilization of old seed following problem can occur in varying degrees: (1) at first is that germination rate descends, even preserve in the seed freezer, germination rate also can annual decline 2-5%, uses if storage more than 3 years, just should not remake seed.If store at ambient temperature, percentage of seedgermination is annual to descend approximately 10%, adds that other maintaining requirement is improper, generally can not do seed again and use.(2) little even percentage of seedgermination descends, but terateger rate increases behind many old seed sproutings, can not become healthy seedling.(3) under the state of field, even old seed germinates, but the ability of emerging weakens, and pushes up native ability drop, causes field emergence irregular, do not reach full stand, Qi Miao.(4) seed promptly enables to be unearthed, but the seedling gesture differs greatly, and does not reach the purpose in neat strong sprout.
Two assorted old seeds have higher economic value usually, under the influence of market economy rule, particularly usually occur large and small year in production, and produce a large amount of seeds and cause the seed stock and become old seed good year.The reasonable utilization of old seed can solve the pressure of seed production, the interests of assurance seeds company, can alleviate the cost input of peasant in agricultural production again, and seed costs descends, and improves agricultural production efficiency.
The reasonable utilization key of old seed is that the vigor that guarantees old seed does not descend, except that improving the seed storage condition, utilize old efficiently seed vitality conditioner to handle to improve the vigor of old seed, can either improve the quality of seed like this, can guarantee the supply of calamity year seed again, also can avoid changing into the economic loss that commodity food causes, will have far-reaching positive meaning seed industry and even whole agricultural production because of seed overstocks.
Summary of the invention
The objective of the invention is to: a kind of method that improves hybrid rice and the old seed vitality of hybrid maize is provided, and this method can improve germination vigor, germination rate and the seedling quality of two assorted old seeds, improves output and lays the first stone for hybrid rice and hybrid maize produce.
Technical solution of the present invention is: adopt conditioning agent to soak old seed of hybrid rice or the old seed of hybrid maize, conditioning agent is the sodium naphthenate of mass concentration 50% and the aqueous solution that zinc sulphate is formed; Soak old kind of period of the day from 11 p.m. to 1 a.m of hybrid rice, the content of sodium naphthenate is 0.7 ml/L in the conditioning agent, and the mass content of zinc sulphate is 0.4%-0.8%, soak time 16h; Soak old kind of period of the day from 11 p.m. to 1 a.m of hybrid maize, the content of sodium naphthenate is 0.2 ml/L in the conditioning agent, and the mass content of zinc sulphate is 0.2%-0.4%, soak time 16h.
The invention has the advantages that adopting accent sodium naphthenate and zinc sulphate to work in coordination with handles two assorted old seeds, science is utilized two hybrid again in agricultural production, improve the production and the utilization ratio of two hybrid, improve the benefit of seed manufacturing enterprise, increasing the economic benefit of peasant planting hybrid rice and hybrid maize, is a kind of agriculture cultivation technology of science.
Embodiment
Below in conjunction with concrete example, the present invention is described in further detail.Should be understood that these embodiment just in order to demonstrate the invention, but not limit the scope of the invention by any way.
Embodiment 1: by 0.7 ml/L sodium naphthenate and 0.6%ZnSO
4The collaborative old seed 16h of hybrid rice that soaks of solution all is immersed in seed in the solution.
Embodiment 2: by 0.2 ml/L sodium naphthenate and 0.3%ZnSO
4The collaborative old seed 16h of hybrid maize that soaks of solution all is immersed in seed in the solution.
Comparative example 1:The collaborative application test effect of sodium naphthenate and zinc sulphate to the old seed vitality of hybrid rice
The old seed of hybrid rice is different batches and stores the II excellent 205 in 2 years, using flushing with clean water again 3 times with seed soaking in 1.0% hydrogenperoxide steam generator behind the 30min, is that the collaborative and equivalent distilled water of 0%, 0.2%, 0.4%, 0.6% and 0.8% solution of zinc sulfate soaks 16h(respectively under 25oC with mass fraction respectively with the sodium naphthenate of getting 0.7mL/L then); Seed broadcast respectively posting corresponding label and be lined with in the culture dish of 4 layers of gauze, 40 in each culture dish repeats 3 times; Under the identical condition of other condition of culture, cultivate, make seed moistening ventilative, guarantee that seed normally germinates.Observe germination during 3d, statistics germination rate during 7d, 15d writes down its germination respectively continuously, by the time 15d measures dry weight respectively, the results are shown in Table 1.
The collaborative influence of table 1 sodium naphthenate and zinc sulphate to old rice seed germination rate
Comparative example 2:The collaborative application test effect of sodium naphthenate and zinc sulphate to the old seed vitality of hybrid maize
The old seed of hybrid maize is different batches and stores the Zheng Dan 958 in 1 year, using flushing with clean water again 3 times with seed soaking in 1.0% hydrogenperoxide steam generator behind the 30min, is that 0.1%, 0.2%, 0.3%, 0.4% and 0.5% solution of zinc sulfate is worked in coordination with and equivalent distilled water soaks 16h(respectively under 25oC with mass fraction respectively with the sodium naphthenate of 0.2mL/L then); Seed broadcast respectively posting corresponding label and be lined with in the culture dish of 4 layers of gauze, 40 in each culture dish repeats 3 times; Under the identical condition of other condition of culture, cultivate, make seed moistening ventilative, guarantee that seed normally germinates.Observe the germination vigor situation during 3d, the statistics germination rate by the time 15d measures the dry weight of overground part and root system respectively, the results are shown in Table 2 during 7d.
