【摘要】 通过对棉花麦垅移栽优化技术组合的纵向比较及其与不同种植方式效益质量的横向比较和复硝钠缩短缓苗期的试验研究，结果表明，实现小麦产量６０００ｋｇ／ｈｍ２，皮棉产量１２００ｋｇ／ｈｍ２的技术组合为：带型８０～７０ｃｍ，苗龄３５～４０ｄ，移栽日期５月２０～２５日，密度７５０００～８００００株／ｈｍ２。更多还原

【Abstract】 The comparisons of the optimal cultivation techniques for cotton ridge planting in wheat field with other techniques in effectiveness and quality, and the experiment on shortening seedling period by sodium ortho nitrophenolate + sodium para nitrophenolate + sodium 5 nitroguaiacolate were made. The results showed that the technique combination for wheat yield of 6 000 kg/hm 2, ginned cotton yield of 1 200 kg/hm 2 was: strip frame of 80￣70 cm, seedling age of 35￣40 d, transplanting period during 20￣25 of May, and density of 75 000￣ 80 000 plants/hm 2.更多还原
