Embodiment 1

[0034] The planting method of this selenium-enriched potato includes:

[0035] Potato planting: choose the light loam paddy field (organic matter content of 16.4g / kg, pH value of 5.1, soil selenium content of 0.45mg / kg) with deep soil layer, good air permeability and convenient drainage and irrigation. Ridge planting is implemented, and each ridge is 1.0-1.1 meters wide, with a width of 70 cm, a height of 30 cm, and a width of 20-25 cm at the bottom of the ditch. Drench enough water and apply enough fertilizer before sowing, and use 45% potassium sulfate compound fertilizer (N-P 2 o 5 -KO 2=15%-15%-15%) 100kg, and 150kg of commercial bio-organic fertilizer (the number of effective viable bacteria ≥ 300 million / g, organic matter ≥ 45%) is applied in the furrows, covered with soil and then sown. Single ridge and double row planting, the spacing between plants and rows is 20×30cm, and the potato seeds are placed in a zigzag pattern on the side of the ditch on the surface of th...

Embodiment 2

[0041] The planting method of this selenium-enriched potato includes:

[0042] Potato planting: choose non-Solanaceae crops, deep soil, good air permeability, and convenient drainage and irrigation in sandy loam (organic matter content 21.9g / kg, PH value 5.2, soil selenium content 0.86mg / kg) dry land planting, implement Ridge planting, each ridge is 1.0-1.1 meters wide, 70 cm wide, 30 cm high, 20-25 cm wide at the bottom of the ditch, flat, straight, and finely divided. Drench enough water and apply enough fertilizer before sowing, and use 45% potassium sulfate compound fertilizer (N-P 2 o 5 -KO 2 =15%-15%-15%) 100kg strips were applied in furrows, covered with soil and sown. Single ridge and double row planting, the spacing between plants and rows is 20×30cm, and the potato seeds are placed in a zigzag pattern on the side of the ditch on the surface of the furrow, and the sowing depth is 5-7cm. During the potato tuber formation period and the tuber rapid expansion period,...

Embodiment 3

[0052] The planting method of this selenium-enriched potato includes:

[0053] Planting of potatoes: choose the light loam slope land (organic matter content 17.9g / kg, PH value 4.4, soil selenium content 0.58mg / kg) with deep soil layer, good air permeability and convenient drainage and irrigation. Ridge planting, each ridge is 1.0-1.1 meters wide, 70 cm wide, 30 cm high, 20-25 cm wide at the bottom of the ditch, flat, straight, and finely divided. Drench enough water and apply enough fertilizer before sowing, and use 45% potassium sulfate compound fertilizer (N-P 2 o 5 -KO 2 =15%-15%-15%) 100kg strips were applied in furrows, covered with soil and sown. Single ridge and double row planting, the spacing between plants and rows is 20×30cm, and the potato seeds are placed in a zigzag pattern on the side of the ditch on the surface of the furrow, and the sowing depth is 5-7cm. 35-40 days after potato emergence (tuber formation period) and 55-60 days (tuber rapid expansion peri...

Abstract

The invention discloses a planting method of selenium-enriched potatoes. Before sowing, water is sufficiently sprayed and fertilizer is sufficiently applied; during sowing, 100 kg of 45% potassium sulfate type compound fertilizer (N-P2O5-KO2=15%-15%-15%) and 150 kg of commodity biology type organic fertilizer (the number of effective viable bacteria is larger than or equal to 300 million g, and organic matter is larger than or equal to 45%) are subjected to drill fertilization into a ridge surface furrow every mu, and sowing is conducted after soil covering; a selenium-enriched nutrient solution is sprayed on leaf surfaces separately, and the mu spraying amount is 45 kg / time; or organic selenium fertilizer is applied, in the potato tuber forming stage and the tuber quick expansion stage, the organic selenium fertilizer is applied to the potatoes separately, the interval of the two times of application is 15-20 days, and 75 kg of the organic selenium fertilizer is applied to every mu of potatoes every time. The selenium content of the obtained potatoes is high, the requirement of people for selenium can be sufficiently met, and the absorption rate of the potatoes in the method is high.

Description

technical field [0001] The present invention relates to potato planting, more specifically, the present invention relates to a kind of planting method of selenium-enriched potato. Background technique [0002] Selenium is an essential trace element for the human body. The Chinese Nutrition Society has also listed selenium as one of the 15 essential nutrients for the human body. A large number of clinical experiments at home and abroad have shown that selenium deficiency in the human body can cause dysfunction in some important organs, leading to many serious diseases. More than 40 countries in the world are in the In selenium-deficient areas, hundreds of millions of people in 22 provinces of China are in selenium-deficient or low-selenium areas. The incidence of tumors, liver diseases, and cardiovascular diseases in these areas is very high. Studies have shown that low-selenium or selenium-deficient crowds can not only prevent tumors, liver diseases, etc. occurrence of cer...
