Problems solved by technology

But so far, there is no effective practical technology applied in production. Even under refrigerated conditions, the germination rate of seeds will decrease year by year, more than 3% per year, and the effect of seeds will be lost. Therefore, long-term preservation of resources and There is also the problem of loss of seed vitality in the national reserve of seeds for drought preparation

Embodiment 1

[0047] Weighing respectively 46.50% by mass percentage of dihydromyricetin extract, 7.50% by mass percentage of resveratrol, 11.00% by mass percentage of vitamin E, 12.00% by mass percentage of vitamin C, and 11.50% by mass percentage Paclobutrazol and 11.50% by mass of agricultural streptomycin sulfate are placed in a blending tank, stirred evenly, and packaged in a composite aluminum bag or canned to obtain a formula product for improving the storage capacity of hybrid rice seeds.

Embodiment 2

[0049] Weigh respectively 47.00% by mass percentage of dihydromyricetin extract, 7.00% by mass percentage of resveratrol, 11.50% by mass percentage of vitamin E, 11.50% by mass percentage of vitamin C, 11.50% by mass percentage Paclobutrazol and agricultural streptomycin sulfate with a mass percentage of 11.50% are placed in a blending tank, stirred evenly, and packaged in a composite aluminum bag or canned to obtain a formula product for improving the storage capacity of hybrid rice seeds.

Embodiment 3

[0050] Example 3: Changes in seed storage capacity of hybrid rice after being treated with formula product of the present invention

[0051] Weigh 500 g of the formula product prepared in Example 1, stir and dissolve it with 50 kg of water to make it into an emulsion, and fill it in a plastic bucket to obtain a 1% seed storage ability improvement formula product for direct use. The above-mentioned direct-use solution was used in four hybrid rice seed production fields of "Taifengyou 208", "Taifeng A", "Wufengyou 2118" and "Guangba Youhuazhan" (under natural growth conditions, rice wax ripening stage Spraying) Spray once, and the amount of spraying is 50kg / mu of direct liquid. During the experiment, a control CK without spraying direct-use liquid was set up at the same time.

[0052] After the seeds matured, the storage capacity of each series of hybrid rice seeds and control CK was measured by accelerated aging method.

[0053] The accelerated aging method of seeds is as fol...

Abstract

The invention belongs to the field of paddy-rice seeds, and discloses a formula for improving the storage capacity of a hybrid-paddy-rice seed as well as a preparation method and application. The formula comprises the following raw materials in percentage by mass: 42.00 to 50.00 percent of dihydromyricetin extract, 4.00 to 8.00 percent of resveratrol, 10.00 to 15.00 percent of vitamin E, 10.00 to 15.00 percent of vitamin C, 10.00 to 15.00 percent of paclobutrazol and 10.00 to 15.00 percent of agricultural streptomycin. All the raw materials are weighed, taken and placed into in a confecting tank according to a mixing proportion, are uniformly agitated and are packed by a composite aluminum bag or canned, so that the formula for improving the storage capacity of the hybrid-paddy-rice seed is subsequently obtained. The formula provided by the invention is reasonable; the processing and the making are simple; the use is convenient and an ideal drug is provided for improving the storage capacity of a seed.

Description

technical field [0001] The invention belongs to the field of rice seeds, in particular to a formula for improving the storage capacity of hybrid rice seeds, a preparation method and an application. Background technique [0002] Seed storage capacity refers to the average number of years that seeds can maintain their vitality under certain storage conditions, that is, the time it takes for seeds to lose their vitality from full maturity. Different from ordinary rice storage, the seed germination rate standard must still be met after storage to meet the needs of crop production. However, the seed vigor and germination rate of ordinary rice will decrease after storage, and the germination rate of hybrid rice seeds can drop below 70% after one year of storage, which cannot meet the production needs and be scrapped, causing huge losses. For the preservation of national strategic wasteland preparation seeds and the long-term storage of seed resources, the technical requirements f...
