Embodiment 1
[0022] A kind of selenium-enriched capsicum high-yield cultivation method of the present embodiment comprises the following steps:
[0023] 1) Selenium-enriched peppers should choose soil with deep, loose, well-drained, medium-to-high fertility, and the previous crops are not Solanaceae crops within 3 years, and the soil blocks have a pH of 6.5;
[0024] 2) Variety selection: The late-maturing variety Xiangyan No. 10 was selected for selenium-enriched peppers cultivated in the open field;
[0025] 3) Seed treatment: Soak the preferred seeds in the organic selenium solution at 30°C for 12 hours. After soaking in the organic selenium solution, the seeds can absorb some organic elements, improve the nutrients of the seeds, increase their germination rate, and prevent Pests and diseases occur; then wash with clean water, and then soak the seeds in warm water at 30°C for 16 hours. After soaking the seeds, put them in a germination box to accelerate germination, control the temperat...
Embodiment 2
[0036] A kind of selenium-enriched capsicum high-yield cultivation method of the present embodiment comprises the following steps:
[0037]1) Selenium-enriched peppers should choose soil with deep, loose, well-drained, medium-to-high fertility, and the previous crops are not Solanaceae crops within 3 years, and the soil blocks have a pH of 7.0;
[0038] 2) Variety selection: choose the early-maturing variety Xiangyan No. 2 for selenium-enriched peppers grown in greenhouses;
[0039] 3) Seed treatment: Soak the preferred seeds in the organic selenium solution at 25°C for 10 hours. After soaking in the organic selenium solution, the seeds can absorb some organic elements, improve the nutrients of the seeds, increase their germination rate, and prevent Pests and diseases occur; then wash with clean water, and then soak the seeds in warm water at 30°C for 20 hours. After soaking the seeds, put them in a germination box to accelerate germination. The temperature is controlled at 35...

Abstract
A high-yield cultivation method for selenium-enriched peppers includes the following steps of: land selection; variety selection; seed treatment; nutrient soil preparation; sowing; planting and transplanting; flower period management of the selenium-enriched peppers; and pepper harvesting. The step of seed treatment is characterized in that: selected seeds are put into an organic selenium solution to soak for 6 to 12 hours, wherein the temperature of the organic selenium solution is 25 to 30 DEG C, and the seeds can absorb a part of organic elements after being soaked in the organic selenium solution, so that the seed nutrients can be improved, the germination rate of the seeds can be increased, and diseases and pests can be prevented; the seeds are washed through clear water, and then are soaked in warm water being at the temperature of 30 DEG C for 10 to 12 hours, the seeds are put into a germination box to germinate, the temperature during germination is controlled to be 28 to 35 DEG C, and the seeds are sown when 70% of the seeds germinate. The step of flower period management of the selenium-enriched peppers is characterized in that: during a flower period of the selenium-enriched peppers, the organic selenium solution is sprayed into leaves of the selenium-enriched peppers for 2 to 3 times, the amount of the organic selenium solution is 10 to 15 Kg per mu, and a time interval between the adjacent two fertilizations is 10 to 12 days. According to the high-yield cultivation method for the selenium-enriched peppers, the content of organic selenium in the planted peppers can reach 4.0 mg / Kg; and compared with the yield of the conventional cultivation method for the selenium-enriched peppers, the yield of the selenium-enriched peppers is increased by greater than 18.3%.
Description
technical field [0001] The invention relates to a pepper cultivation method, in particular to a high-yield cultivation method for selenium-enriched pepper. Background technique [0002] Selenium is an essential trace element for the human body, which has biological properties such as anti-cancer, anti-aging, improving human immunity, and antagonizing heavy metals. Selenium in the food chain mainly comes from soil. If the distribution of selenium content in soil in different regions is uneven, it is an important direction for agricultural production research to implement and carry out targeted selenium-enrichment work based on local selenium-poor soil clues. Optimizing the selenium content level in the food chain is an important direction for agricultural production research. The Chinese Nutrition Society recommends a per capita daily selenium intake of 50-200 μg. But now the daily selenium intake of adults in our country is only 26-32 μg, and the situation of selenium maln...
