Embodiment 1
[0024] Embodiment 1: a kind of planting method that uses selenium-enriched coating to plant selenium-enriched peas, comprises the following steps:
[0025] a. Preparation of soaking solution: Weigh 3g of sodium selenite with a purity of more than 98% and 10g of potassium permanganate in a basin or bucket, first add 1L of water, stir to dissolve, then add 9L of water, stir evenly, and prepare 0.03% Sodium selenite-0.1% potassium permanganate mixed soaking solution;
[0026] b. Sodium selenite coating agent preparation: take 20g of sodium selenite and 20g of zinc sulfate with a purity of more than 98% in 1kg of plant ash, mix evenly, mix in 50kg of plant ash, stir and mix evenly by hand or mechanically, and become a seed Potato coating agent, containing more than 400mg / kg of selenium;
[0027] c. Seed soaking treatment: select mature, high-quality pea seeds, immerse in the sodium selenite-potassium permanganate soaking solution prepared in step a, and soak for 3min-10min;

Embodiment 2
[0032] Embodiment 2: a kind of planting method of planting selenium-enriched peas using selenium-enriched coating, comprises the following steps:
[0033] a. Preparation of soaking solution: Weigh 3g of sodium selenite with a purity of more than 98% and 10g of potassium permanganate in a basin or barrel, first add 1L of water, stir to dissolve, then add 9L of water, stir evenly, and prepare 0.03% Sodium selenite-0.1% potassium permanganate mixed soaking solution;
[0034] b. Sodium selenite coating agent preparation: take 20g of sodium selenite and 20g of zinc sulfate with a purity of more than 98% in 1kg of plant ash, mix evenly, mix in 50kg of plant ash, stir and mix evenly by hand or mechanically, and become a seed Potato coating agent, containing more than 400mg / kg of selenium;
[0035] c. Seed soaking treatment: select mature, high-quality pea seeds, immerse in the sodium selenite-potassium permanganate soaking solution prepared in step a, and soak for 3min-10min;

Embodiment 3
[0043] Embodiment 3: A planting method of planting selenium-enriched peas using selenium-enriched coating, according to claim 1, a planting method of planting selenium-enriched peas using selenium-enriched coating, choose healthy, disease-free pea seeds 10kg, Randomly divided into 2 parts, one for seed soaking and coating treatment, and the other for direct sowing, planted in areas where late blight and bacterial wilt are common, managed according to conventional methods, and observed the incidence of pea late blight, bacterial wilt and fusarium wilt , weighed after harvesting, and took samples to determine the selenium content. The results are shown in Table 1.
[0044] Table 3 Selenium content and disease prevention effect of selenium-enriched coated seed potatoes on pea
[0045]
[0046]
[0047] It can be seen from Table 1 that the production of selenium-enriched coated peas can not only greatly increase the selenium content of peas, but also increase yield and effec...
