Embodiment 1
[0041] Field test location: Huixian Town, Lingui County, Guilin City, Guangxi Province, with medium fertility. The basic physical and chemical properties are listed in Table 1.
[0042] Table 1 Basic chemical properties of the tested soil
[0043]
[0044] Rice for testing: Zhongguangxiang No.1.
[0045]The cultivation method of the organic selenium-enriched rice in this embodiment includes seed selection, seedling raising, field plowing, seedling transplanting, field management, and harvesting. The seedling-raising substrate used for seedling raising is selenium-rich seedling-raising substrate, sow 0.8 kilograms of bud seeds per square meter, and cover the seeds with a thickness of 0.5 centimeters. The fertilizer applied by field management is selenium-rich organic and inorganic fertilizer:
[0046] (1) The first application: Before rice transplantation, apply 35 kg of selenium-rich organic and inorganic special fertilizer as base fertilizer; after plowing the land, eve...
