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 life in the national stockpile of wild seeds

Embodiment 1

[0051] Take by weighing respectively the vine tea extract that mass percentage is 25.00%, the bitter almond extract that mass percentage is 20.00%, the clove oil extract that mass percentage is 7.50%, the tea tree essential oil extract that mass percentage is 12.50%, the mass percentage is 20.00% coumarin extract, 7.50% paclobutrazol and 7.50% agricultural streptomycin 72% wettable powder are placed in a blending tank, stirred evenly, and packaged in a composite aluminum bag or The composite rice seed life prolonging agent can be obtained after canning.

Embodiment 2

[0053] Take by weighing respectively the vine tea extract that mass percentage is 24.50%, the bitter almond extract that mass percentage is 20.50%, the clove oil extract that mass percentage is 7.50%, the tea tree essential oil extract that mass percentage is 12.50%, mass percentage is 20.50% coumarin extract, 7.00% paclobutrazol by mass percentage and 7.50% agricultural streptomycin 72% wettable powder are placed in a blending tank, stirred evenly, and packaged in a composite aluminum bag or The composite rice seed life prolonging agent can be obtained after canning.

Embodiment 3

[0054] Embodiment 3: "368" series hybrid rice seeds are treated with the compound rice seed life-extending agent of the present invention, and the variation of seed life prolongation

[0055] Take by weighing 500g of the composite rice seed life prolonging agent prepared in Example 1, stir and dissolve with 50kg water to make it into an emulsion, and fill it in a plastic bucket to obtain a 1% rice seed life prolonging agent direct-use liquid . Spray the above-mentioned direct-use solution on four hybrid rice seed production fields of "Boyou 368", Tianyou 368", "Qiuyou 368" and "IIyou 368" (under natural growth conditions, spraying at the early stage of rice wax ripening) 1 time, the amount of spraying is 50kg / mu of direct-use liquid. During the experiment, a control CK without spraying direct-use liquid was set up at the same time.

[0056] After the seeds are mature, the life expectancy of the seeds produced in the field of each series of hybrid rice is measured by accelerat...

Abstract

The invention belongs to the field of rice seeds, and discloses a composite rice seed life extension agent, a preparation method and an application thereof. The composite rice seed life extension agent is made of the following raw materials in terms of mass percentage: vine tea extract 21.00-27.00%, bitter almond extract 17.00-25.00%, clove oil extract 5.00-10.00%, tea tree essential oil extract 10.00-15.00%, coumarin extract 17.50-22.50%, paclobutrazol 5.00-10.00%, agricultural streptomycin 72% wettable powder 5.00-10.00%. All raw materials are weighed according to the above ratio and placed in a blending tank, stirred evenly, packed in a compound aluminum bag or canned to obtain the composite rice seed life-extending agent. The invention has reasonable formula, simple processing and convenient use, and provides an ideal medicine for prolonging the life span of rice seeds.

Description

technical field [0001] The invention belongs to the field of rice seeds, and in particular relates to a composite rice seed life-extending agent and a preparation method and application thereof. Background technique [0002] Seed longevity 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 fully mature to lose their vitality. In actual production, the lifespan of seeds is a group concept, which refers to the period from harvesting to when the germination rate of a batch of seeds is reduced to 50%, also known as the half life of seeds. Under normal conditions, when rice is stored, the seeds deteriorate, and the germination rate decreases. Especially, the germination rate of hybrid rice seeds can drop below 70% after one year of storage, which cannot meet the production needs and is scrapped, causing huge losses. For the preservation of national strategic wasteland preparation ...
