Embodiment 1

[0017] A planting method of selenium-enriched rice, comprising the following steps:

[0018] (1) Seed treatment: soak the seeds in 800 times carbendazim solution for 64 hours, stir once every 4 hours, so that the upper and lower seeds are evenly covered with the drug, remove the seeds after disinfection, and then soak the seeds in dilute sulfuric acid for 10 minutes , rinsed with clean water several times, then treated with hydrogen peroxide for half an hour, rinsed with clean water, and finally added 1 / 10000 of its weight of sodium selenite to the seeds, mixed thoroughly and placed in a constant temperature box at 30°C to accelerate germination. Start sowing after the seeds are white;

[0019] (2) Transplanting: Transplanting when the seedlings were 30 days old, transplanting 16,000 holes per mu, 3 seedlings per hole, row spacing 20*22cm;

[0020] (3) fertilization management: during the growth period of paddy rice, apply nutrient; Described nutrient is mainly made up of nuc...

Embodiment 2

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

[0025] (1) Seed treatment: soak the seeds in 1000 times carbendazim solution for 72 hours, stir once every 6 hours, so that the upper and lower seeds are evenly covered with the drug, remove the seeds after disinfection, and then soak the seeds in dilute sulfuric acid for 15 minutes , rinsed with clean water several times, then treated with hydrogen peroxide for half an hour, rinsed with clean water, and finally added sodium selenite of 1 / 10000 of its weight to the seeds, mixed them thoroughly and placed them in a constant temperature box at 40°C to accelerate germination. Start sowing after the seeds are white;

[0026] (2) Transplanting: Transplanting when the seedlings were 35 days old, transplanting 18,000 holes per mu, 4 seedlings per hole, row spacing 20*22cm;

[0027] (3) Fertilization management: during the growth period of paddy rice, apply nutrient; Described nutrient is mainly mad...

Embodiment 3

[0031] A planting method of selenium-enriched rice, comprising the following steps:

[0032] (1) Seed treatment: soak the seeds in 900 times carbendazim solution for 68 hours, stir once every 5 hours, so that the upper and lower seeds are evenly covered with the drug, remove the seeds after disinfection, and then soak the seeds in dilute sulfuric acid for 13 minutes , rinsed with clean water several times, then treated with hydrogen peroxide for half an hour, rinsed with clean water, and finally added sodium selenite of 1 / 10000 of its weight to the seeds, mixed them thoroughly and placed them in a constant temperature box at 35°C to accelerate germination. Start sowing after the seeds are white;

[0033] (2) Transplanting: Transplanting when the seedlings were 33 days old, transplanting 17,000 holes per mu, 3.5 seedlings per hole, row spacing 20*22cm;

[0034] (3) fertilization management: during the growth period of paddy rice, apply nutrient; Described nutrient is mainly ma...

Abstract

The invention discloses a method for planting selenium-rich rice. The method comprises the following steps: (1) seed treatment; (2) transplanting; (3) fertilization management; (4) field management weeding and deinsectization; (5) harvesting and storage. In the mehtod, various nucleotide salts and deoxynucleotide salts are reasonably matched with each other, and the contents of amino acid, sugar and other organic and inorganic auxiliaries are relatively high, so that the effects of increasing the yield, increasing the income, improving the efficiency, enhancing the resistance and improving thequality are good; by adopting a selenium-enriched nutrient solution, the selenium-enriched rice is cultivated without adding any hormone, the selenium content of the obtained rice is high, , the required selenium quantity of a human body can be effectively supplemented by often eating the rice, the occurrence of selenium deficiency of the human body can be effectively prevented, and the production cost is low.

Description

technical field [0001] The invention relates to a planting method of selenium-enriched rice. Background technique [0002] Rice is the main food crop in our country, and it is widely planted in South China, Central China, North China, Southwest China, Northeast China and other places. The rice planting industry supports our agricultural planting industry and provides rice grain to the people of the whole country and even the people of the world. There are a lot of arable land, and the per capita area of ​​arable land is small, and the food problem is a fundamental issue related to people's livelihood. Therefore, as long as there is sufficient irrigation water, rice with high yield is generally planted. The needs of growing agriculture, and some of the rice planted in the prior art contains pesticide residues, which to a certain extent are harmful to the health of consumers. [0003] Selenium is a chemical element with the chemical symbol Se. It is located in the VIA group o...
