Abstract

The invention discloses a planting method of selenium-rich potatoes. The planting method comprises following steps: uniformly cutting potato tubers before sowing to ensure that 1 to 2 buds grow in each tuber, washing tubers for 2 to 4 times by clear water and soaking seeds by utilizing selenium-rich diluents; smearing or spraying diluents of selenium-rich fertilizers to stems of potato land during the bud-growing period; and watering after bud-appearing period instead of watering prior to the bud-appearing period and spraying selenium-rich fertilizers of selenium-rich diluents to leaf surfaces. Compared with a conventional planting method, the planting method of selenium-rich potatoes has following beneficial effects: during different periods, selenium-rich diluents are adopted for soaking seeds of potatoes, smeared or sprayed to stems and sprayed to leaf surfaces, absorptive amount of selenium is increased by potatoes; potatoes are planted in a selenium deficient area such that the selenium content can reach 60 to 100 [mu]g / kg; and meanwhile, sizes of potatoes are increased so that per mu yield of potatoes is up to more than 3500 kilograms, thereby harvesting high-quality high-yield potatoes.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a method for planting selenium-enriched potatoes. Background technique [0002] Potatoes have a long history of planting. The yield per mu of potatoes planted by traditional planting methods is about 3,000 kilograms. In the process of continuous improvement, research is mainly aimed at potato diseases, insect pests and quality problems. Therefore, chemical fertilizers and pesticides are invested in the process of planting. The large amount will further deteriorate the soil, and at the same time, the ecological environment will be destroyed. The distribution of selenium in China is quite different, and many areas are severely deficient in selenium, resulting in less selenium content in crops. At present, the selenium-enriched amount of potatoes in selenium-deficient areas is about 10 μg / kg, and the selenium-enriched amount of potatoes in selenium-enriched...
