Method for planting selenium-enriched rice at high yield

The invention provides a method for planting selenium-enriched rice at a high yield. The method comprises the following steps: 1), preprocessing seeds; 2) plowing the soil and fertilizing; 3) culturing seedlings; 4) transplanting the seedlings; 5) additionally fertilizing; 6) harvesting. According to the method provided by the invention, a seed processing step is additionally adopted to sterilize and disinfect the seeds, and meanwhile, the seeds are soaked with sodium selenite to increase the selenium content in rice seeds. A long-acting selenium-enriched coated controlled release compound fertilizer applied for rice planting comprises a core fertilizer and a coated layer coating the surface of the core fertilizer. The core fertilizer adopts sulphur coated urea to form a three-layer structure, such that the controlled release efficiency is remarkable, and the fertilizer efficiency is long. Only a little amount of fertilizer needs to be applied additionally after planting to save time and labor. Both the core fertilizer and the coated layer are prepared from organic degradable materials, such that the fertilizer efficiency can be kept in the degradation process. The core fertilizer is rich in microelements, thus promotes the nutrimental value of rice, and the soil quality can also be improved on the premise of degradability. The ingredients of the fertilizer are friendly to soil, low in production cost, beneficial for market promotion and good in economic benefits.
