QianYu 417 is a medium indica cultivar developed by our “Seventh Five-Year Plan”. In order to promote popularization and increase yield and benefits, we conducted a pilot study on the cultivation techniques of this cultivar from 1990 to 1992. First, the pilot profile and test content Test mainly in southern Henan and Guizhou Anlong, Guiyang. Henan pilot, located between latitude 31 ~ 33 °, with an average annual temperature of 14.8 ~ 15.1 ℃, annual rainfall of 900 ~ 1000 mm, is the main rice producing areas in Henan Province, is also the mid-indica high latitude provinces. Guizhou Anlong and Guiyang, latitude 24.51 ~ 26.35 °, elevation 1140 ~ 1360 meters, annual average temperature 15 ~ 15.2 ℃, rainfall 1128 ~ 1256 mm, is rice, rice
