Embodiment 1
[0025] First, choose a selenium-rich land with good ecology, no pollution, fertile soil, convenient irrigation, and no harmful substances as the planting base; then deep plow the selected selenium-rich land, requiring deep plowing of 19-23 cm in autumn, and applying organic fertilizer 1800 -2200 kg per mu, ammonium bicarbonate 50 kg per mu, seed fertilizer diammonium phosphate 12-17 kg, randomly sowed by layered seeders; then 15 days before sowing, choose sunny weather for continuous drying for 2-4 days After drying the seeds, first use 45°C water to pre-soak the rice seeds. After pre-soaking, use 2-2.5 grams of 75% Weifu warming powder (containing thiram 37.5%) per kilogram of seeds to dress the seeds. Or choose 32ml of 20% Fenxiinin mixed with 50kg of water for soaking; after the seed treatment is completed, start sowing in mid-December of the Gregorian calendar, with a sowing depth of 3-4 cm, a rice row spacing of about 12 cm, and a seeding rate of 17 kg per mu Then, when t...
Embodiment 2
[0027] In Embodiment 1, the following steps are added:
[0028] The planting base in the step (1) is the sandy soil land that has been rotated for more than three years.
[0029] First, choose a selenium-rich land with good ecology, no pollution, fertile soil, convenient irrigation, and no harmful substances as the planting base; the planting base is a sandy soil land that has been rotated for more than three years, and then carry out deep plowing on the selected selenium-rich land. Autumn deep plowing of 19-23 cm, 1800-2200 kg of organic fertilizer per mu, 50 kg of ammonium bicarbonate per mu, 12-17 kg of seed fertilizer diammonium phosphate, randomly sown by layered seeders; When the weather is good, choose sunny weather to sun-dry the seeds continuously for 2-4 days. After the sun-dried seeds are completed, first use 45°C water to pre-soak the rice seeds. After the pre-soaking treatment, use 75% Weifu warmable powder ( Contain thiram 37.5%) 2-2.5g for seed dressing or choo...
Embodiment 3
[0031] In embodiment two, add the following steps:
[0032] When spraying "Selenium-enriched Yield-Increasing Element" in step (5), avoid cloudy days. The spraying time is: 9-10 am, after 4 pm, and if it rains within 24 hours after spraying, it needs to be sprayed , The fourth time to water depends on the dryness and wetness of the ground. Determine the amount of watering according to the soil moisture content, and do it on a windless day to prevent lodging.
[0033]First, choose a selenium-rich land with good ecology, no pollution, fertile soil, convenient irrigation, and no harmful substances as the planting base; the planting base is a sandy soil land that has been rotated for more than three years, and then carry out deep plowing on the selected selenium-rich land. Autumn deep plowing of 19-23 cm, 1800-2200 kg of organic fertilizer per mu, 50 kg of ammonium bicarbonate per mu, 12-17 kg of seed fertilizer diammonium phosphate, randomly sown by layered seeders; When the wea...
