Mixed type agent for restoring activity of deteriorated rice seed embryo, preparation method and application of mixed type agent

Abstract

The invention belongs to the technical field of seed priming, and discloses a mixed type agent for restoring activity of a deteriorated rice seed embryo, a preparation method and an application of the mixed type agent. The mixed type agent comprises the raw materials such as a vine tea extract, a tea extract, an N element fertilizer, a P element fertilizer, a K element fertilizer and a humic acid fertilizer; and the parts by weight of the vine tea extract, the tea extract, an effective component N in the N element fertilizer, an effective component P2O5 in the P element fertilizer, an effective component K2O in the K element fertilizer and an effective component humic acid in the humic acid fertilizer are respectively 0.50-41.50 parts, 24.50-25.50 parts, 6.75-7.35 parts, 10.25-10.75 parts, 13.50-14.50 parts and 2.25-2.75 parts. The mixed type agent is reasonable in formula, fully utilizes respective characteristics of all raw materials, is reasonable in blending, and meets the requirements of all functions and nutrients required by restoring the activity of the rice seed embryo.

Description

technical field [0001] The invention belongs to the technical field of rice seed initiation, and in particular relates to a hybrid rice seed embryo vitality restoring agent and a preparation method and application thereof. Background technique [0002] China is a large developing country with a population of more than one billion. Food security has always been a major strategic issue related to economic development, social stability and national security. Rice is my country's main food crop, accounting for more than half of the country's total grain output, and plays an extremely important role in food security. The annual sown area of ​​rice in my country is about 30 million hectares, and the annual seed quantity is quite large. Due to the complexity of rice seed production and the unpredictability of the seed market, coupled with global climate change, extreme weather and frequent natural disasters, inter-annual adjustments to large rice seed storage are often required. ...

Problems solved by technology

[0008] Although various initiators have their own characteristics, the disadvantages are also obvious: PEG has the properties of a colloid, and its solution can obtain a lower water potential, and it has no toxic effect on the seeds, but its viscosity is relatively large, and the oxygen solubility in the solution Low, and the amount is large, the cost is high

The action mechanism of PVA is similar to that of PEG, which has the advantages of less dosage and low cost, but the triggering effect is not ideal and cannot meet the production requirements.

Inorganic salt ions are generally used in small amounts and the cost is relatively low, but the ions of inorganic salts can penetrate into the seeds and accumulate in the seeds during the treatment process, thereby reducing the osmotic potential of the seeds, causing the seeds to absorb more water and reducing the germination rate

Appropriate hormone (such as gibberellin, etc.) treatment usually has a promotion effect on the lifespan, viability or germination ability of fresh seeds, but the treatment of deteriorating seeds with hormones, except for individual hormones or concentrations that have no obvious reduction in seed vigor, the overall The trend is that hormone treatment significantly inhibits seed germination, so treating deteriorating seeds with hormones is not a good way to revive and improve the vigor of deteriorating seeds

After rice seeds are treated with antibiotics, rare earth elements La or Ce, although the seed vigor is significantly increased, the toxicity of the agents and the side effects on environmental pollution cannot be underestimated. Negative effects of the system will affect the sustainable use of farmland ecosystems

Using physical methods such as high-voltage electrostatic field and simulated microgravity treatment to revive the vitality of deteriorating seeds requires special equipment, high cost, and the possibility of gene mutation
