Problems solved by technology

However, due to regional inhomogeneity in the distribution of selenium content in the soil in selenium-enriched areas, this production method is difficult to control the selenium content of rice, and there are regional limitations and content variability, which is not conducive to large-scale standardized production

Embodiment 1

[0024] A method for raising seedlings of selenium-enriched rice, comprising the following steps:

[0025] (1) Seed treatment: choose pure and plump seeds to dry in sunny days for 2 days, turn the seeds every 2 hours during the drying period, soak and disinfect the seeds with strong chlorine solution after drying, and rinse with sterile water for 2-5 and drain the water naturally;

[0026] (2) Seed soaking and accelerating germination: soak the drained seeds in a germination agent with a temperature of 30°C for 25 hours, then remove them and spread them out in a culture vessel, and spray the germination agent to keep the surface of the seeds moist until 90% of the seeds When the long buds of 0.3cm grow out, the seeds are spread out and dried to obtain the rice buds; 0.2 parts of tea polyphenols, 2 parts of vitamin C, and 400 parts of water.

[0027] (3) Making seedbed soil: the pond mud is dried and broken through a 30-mesh sieve as the seedbed soil base material, and the see...

Embodiment 2

[0030] A method for raising seedlings of selenium-enriched rice, comprising the following steps:

[0031] (1) Seed treatment: choose pure and plump seeds to dry in sunny days for 3 days, turn the seeds every 3 hours during the drying period, soak and disinfect the seeds with strong chlorine solution after drying, and rinse with sterile water for 2-5 days and drain the water naturally;

[0032] (2) Seed soaking and accelerating germination: soak the drained seeds in a germination agent with a temperature of 40°C for 40 hours, then remove them and spread them out in a culture vessel, and spray the germination agent to keep the surface of the seeds moist until 98% of the seeds When growing 1 cm long buds, the seeds are spread out and dried to obtain rice bud seeds; the germination agent consists of the following raw materials in parts by weight: 0.2 parts of cyanamide, 4 parts of ammonium molybdate, 4 parts of ferric diamine fulvic acid , 0.3 parts of tea polyphenols, 5 parts of...

Embodiment 3

[0036] A method for raising seedlings of selenium-enriched rice, comprising the following steps:

[0037] (1) Seed treatment: select pure and plump seeds and dry them in sunny days for 2.5 days. During the drying period, turn the seeds every 2.5 hours. Drain water naturally;

[0038](2) Seed soaking and accelerating germination: soak the drained seeds in a germination agent at a temperature of 35°C for 28 hours, then remove them and spread them out in a culture vessel, and spray the germination agent to keep the surface of the seeds moist until 95% of the seeds When the long buds of 0.5 cm grow out, the seeds are spread out and dried to obtain rice buds; the germination agent has the following raw materials in parts by weight: 0.1 part of cyanamide, 3.5 parts of ammonium molybdate, 3.4 parts of ferric diamine fulvic acid parts, 0.2 parts of tea polyphenols, 4 parts of vitamin C, and 500 parts of water.

Abstract

The invention relates to the technical field of agricultural production, in particular to a selenium-rich rice seedling raising method which includes the steps: (1) seed treatment: selecting pure and full seeds, sunning the seeds in sunny days for 2-3 days, soaking and disinfecting the seeds after sunning the seeds, and rinsing the seeds with sterile water; (2) seed soaking and germination accelerating: placing the drained seeds into a culture vessel, spraying germination accelerating agents and keeping seed surfaces humid; (3) seedling bed soil making: making seedling bed soil with pond sludge, straw fermentation broth, chitin, medical stones, humic acid, propiconazole, urea, selenium-rich mineral substances, nitrogen fertilizers and potassium fertilizers; (4) rice seedling raising: placing the seedling bed soil into a seedling raising tray, placing the seedling raising tray into a seedling raising shed, sowing bud seeds into the seedling raising tray, uniformly covering the soil and dropping water after sowing. According to the rice seedling raising method, the disease resistance and the germinating capacity of rice seedlings are improved, and the rice seedlings have high survival rate.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a selenium-enriched rice seedling raising method. Background technique [0002] Rice is one of the most important food crops in the world, and nearly half of the world's population uses rice as a staple food. my country is a big rice planting country, and the planting area is basically maintained at about 420-450 million mu. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle-late rice, glutinous rice and non-glutinous rice. There are various ways to eat rice, rice porridge, rice cakes, rice cakes, rice noodles, etc. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining. Rice husks and rice straws also have many uses. However, at present, the survival rate of transplanted rice seedlings cannot be improved as much as possible, the yield is small, ...
