Over the past five years at the station, the average result was 15.84% more than Sword cotton and lint cotton, an average increase of 6.28% over the previous three years. From 1956 to 1958, he took part in the regional experiment of cotton varieties throughout the country, which showed a number of performance increases, especially in Luoyang in the past three years. Comparison of test results: According to the three-year trial results of Luoyang Institute of Agricultural Sciences (see Table 1), the yield of seed cotton is 8.9-23.7% more than that of the control (Siqianmian 4). Three-year average of 17.7%, lint yield 19.07-40.4%, an average of 31.95%. In the past three years, the Dai Ziwo 15 # seed cotton production, which is under promotion, increased by 8.5%
