A 100-mu area demonstration of hybrid rice Teyou 233 and its super-high yield cultivation technology

Teyou233 is a three-line hybrid rice combination bred by Yulin Agricultural Science Research Institute.It was certified and registered by Guangxi Committee for Crop Variety Registration in December,2000.In 2007,a 100-mu area demonstration of super-high yield cultivation of Teyou 233 in early season was conducted in Caiwang Village of Min'an Town,Beiliu City.In the demonstration process,a series of cultivation measures were applied,for example: timely early sowing and thin sowing were applied to cultivate strong seedling,seedlings were transplanted timely to obtain lower tiller,and balanced fertilization and timely top dressing were done.Moreover,the scientific irrigation and drainage was applied and the disease and insects pest were controlled.For these measures,the average yield of Teyou 233 reached 11.08 t/hm2,as compared to control Teyou 63,the yield increased 12.8%.
