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 promotio...

Embodiment 1

[0040] Weigh 41kg of vine tea extract, 25kg of tea extract, 10.72kg of urea (N% in urea = 46%), 20.38kg of potassium dihydrogen phosphate (P in potassium dihydrogen phosphate) 2 O 5 %=51.50%, K in potassium dihydrogen phosphate 2 O%=34%), 15.37kg potassium nitrate (K in potassium nitrate 2 O% = 46%, N% in potassium nitrate = 13.50%) and 3.57kg of sodium humate (the content of humic acid in sodium humate is 70%) is placed in the mixing tank, stirred evenly, and packed in aluminum bags or tanks After filling, 116.04 kg of mixed-type rice seed embryo vitality restoring agent was obtained. In this embodiment, the N provided by 10.72kg of urea is 4.93kg, and the P of 10.50kg provided by 20.38kg of potassium dihydrogen phosphate 2 O 5 and 6.93kg of K 2 O, 15.37kg potassium nitrate provides 7.07kg K 2 O and 2.07kgN, 3.57kg sodium humate provides 2.50kg humic acid, therefore, N in this embodiment is 7kg, P 2 O 5 10.5kg, K 2 O is 14kg, humic acid is 2.50kg, rattan tea extract:...

Embodiment 2

[0042] Weigh 11.604 kg of the embryo viability restorer prepared in Example 1, heat it with 1000kg of water, stir to dissolve, and fill it with a plastic bucket to obtain a 1% mass percentage of the embryo viability restorer treatment direct liquid. The rice seeds that are about to be scrapped were soaked in the direct treatment solution of embryo vitality restorer for 12 to 24 hours, and then dried for germination rate experiments. Compared with the seeds without any treatment, the final germination rate of the seeds increased by 3. ~6%.

Embodiment 3

[0043] Example 3: Germination of rice seeds before and after treatment with embryo vigor restorer

[0044] Weigh 11.604kg of the embryo vitality restorer prepared in Example 1 and 2000kg of water, and fully dissolve the embryo vitality restorer into the water under heating and stirring to prepare a 0.5% rice degenerate seed embryo vitality restorer. liquid. Divide the above-mentioned degraded rice seed embryo vitality restoration agent into 2 equal parts, respectively take 2000kg of "Tianyou 216" and "Tianyou 998" inferior rice seeds and place them in the prepared and cooled liquid, respectively. After soaking for 12 hours and 24 hours, the recovered seeds are placed in a cool dry place to dry naturally (back-drying).

[0045] The same batch of seeds of the same combination without any treatment was used as the experimental control (CK), and the same combination and the same batch of seeds were soaked in water for 12 h and soaked in water for 24 h, and the drying method was t...

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. ...
