Quality-ensuring aroma-ensuring high-yield cultivation method of rice

Abstract

The invention relates to the technical field of rice planting and discloses a quality-ensuring aroma-ensuring high-yield cultivation method of rice, comprising determining seeding time, applying fertilizers, carrying out water-saving cultivation, harvesting, sun-curing rice and other steps. The seeding time of Nong Xiang 32 is optimized, the negative effect of the high-temperature summer environment in August upon the fruiting rate and yield of Nong Xiang 32 in earing and flowering stage is avoided, the fruiting rate and yield of Nong Xiang 32 are increased, application rate of nitrogen fertilizer and quantity of irrigation water are decreased, agricultural area-source pollution of rice is relieved at the premise of saving water and saving cost, the anti-lodging capacity of Nong Xiang 32 plants is improved, the rice from Nong Xiang 32 has better aroma and taste, and commercial value of Nong Xiang 32 is increased.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a high-yield and high-yield cultivation method for rice. Background technique [0002] High-grade and high-quality fragrant rice Nongxiang 32 is the main high-grade and high-quality rice variety in Hunan Province, and it is also the gold medal variety in the second national food tasting. [0003] Nongxiang 32 is a medium-maturing rice variety with a long growth period of about 135 days. The safe sowing period is generally from April to mid-June. At present, the majority of producers are used to sowing in mid-to-late April, resulting in Nongxiang. The heading and flowering period of 32 happened to coincide with the high temperature in mid-summer in August in the middle and lower reaches of the Yangtze River, which resulted in a decrease in the seed setting rate and yield of Nongxiang 32. Due to the high nitrogen fertilizer application and excessive irrigation water consumpti...

Problems solved by technology

[0003] Nongxiang 32 is a medium-maturing rice variety with a long growth period of about 135 days. The safe sowing period is generally from April to mid-June. At present, the majority of producers are used to sowing in mid-to-late April, resulting in Nongxiang. The heading and flowering period of 32 happened to coincide with the high temperature in mid-summer in August in the middle and lower reaches of the Yangtze River, which resulted in a decrease in the seed setting rate and yield of Nongxiang 32. Due to the high nitrogen fertilizer application and excessive irrigation water consumption in rice planting areas, As a result, agricultural non-point source pollution in rice planting areas has become increasingly serious; in addition, the current rice harvesting time is generally when the rice maturity reaches 90%-95%, so that the unique aroma of Nongxiang 32 is not strong, and the rice quality is not good , bad taste
