我所曾于1964～1965年、1977～1980年连续进行棉花栽培试验,初步探索亩产皮棉100～125公斤的高产栽培技术及其生育规律,为我区大面积高产、稳产提供理论依据.现将六年试验结果汇总分析如下:我所位于北纬35°05′,东经115°20′,黄河冲积平原,海拔50米,属半湿润温暖农业气候地区.大陆性季风气候显著.年生理辐射59.70千卡/厘米~2,平均全年日照为2579小时,棉花生育期间(4月20日至10月31日),日照时数为1536小时,年平均气温
I have been in 1964 ~ 1965, 1977 ~ 1980 continuous cotton cultivation experiments to initially explore the high yield of 100-150 kg per mu lint cultivation techniques and their fertility rules for our area large area of high yield and stable production provide a theoretical basis. The results of the six-year trial are summarized as follows: We are located in the subtropical agro-climatic region at 35 ° 05 ’north longitude 115 ° 20’E and the alluvial plain of the Yellow River at 50 meters above sea level. The continental monsoon climate is remarkable. The annual physiological radiation is 59.70 thousand Card / cm ~ 2, the average annual sunshine is 2579 hours, cotton growth period (April 20 to October 31), sunshine hours for 1536 hours, the annual average temperature
