摘要
Abstract
[ Objective ] The aim was to study high-yielding cultural techniques of keza 2 cotton for large area demonstration and popularization in changjiang river cotton areas. [ Method ] Using the four elements quadratic regression orthogonal rotational combination design in this experiment , high-yielding cultural techniques of keza 2 was studied. The mathematical model was set up , and its significance test was conducted. [ Result]The study showed that the optimal agronomic measure was density of 21 606 -22 394 株/hm2, N of 234. 3-266. 1 kg/hm2, P2O5of 85.2 - 114.8 kg/hm2, K2O of 186.0-214. 8 kg/hm2. [Conclusion] The mathematical mode was used in production as high-yielding cultural techniques of keza 2.关键词
