摘要： [目的]研究杏棉间作下棉花的生长发育,为杏棉立体高效种植技术的优化提供理论支撑.[方法]进行间作棉与单作棉对比试验.[结果]间作棉比单作棉生育期晚8 d;出叶速率在出苗-现蕾期最快,间作棉为6.2 d/片,比单作棉慢0.7 d/片;截至打顶时,间作棉株高为58.01 cm,单作棉为64.51 cm;间作下棉花的真叶数、果枝数减少,主茎节间变长,始节高度上长升,总果节数比单作棉低53.47;,收获株数18.34×10<'4>株/hm2,单株结铃数3.6个,单铃重5.25 g,衣分38.6;,皮棉产量1 352.84 kg/hm2.[结论]杏棉间作条件下主要影响棉花的衣分、产量.其中衣分比单作棉低4.3;、产量低43.8;.
