枣棉间作条件下棉花各种植行生长差异研究

Study on Growth Differences of Different Cotton Planting Row under the Condition of Intercropping Jujube and Cotton

在3年生枣树田间作棉花条件下,研究棉花距枣树的不同种植行的生长发育情况,为枣树成林前与棉花间作的种植模式提供理论依据。结果表明:在3年生枣树与棉花间作且棉花边行距枣树0.9 m以上条件下,不同种植行的生育期差异不大;棉花中间行较边行表现出生长优势,产量较边行高,但铃重、衣分和纤维品质无显著差异。

Under the condition of intercropping of cotton and jujube in three years, the growth and development situation of different cotton planting row were studied, providing the theory basis for planting model of jujube and cotton intercropping.The results showed that： cotton edge spaced jujube more than 0.9m, the growth period difference of different plant row was not obvious; cotton in the middle row showed growth advantage, the yield was higher than the edge row; but boll weight lint percentage and fiber quality were no significant differences.
