摘要： 为了解决新疆棉花苗期受干旱、盐碱等自然因素导致棉花出苗保苗率低问题,首次筛选出能提高棉花苗期抗旱、耐盐碱能力的种衣剂,2006和2007年将室内研制的种衣剂进行田间小区试验,结果表明,三个种衣剂配方均能提高干旱和盐碱胁迫下棉花田间出苗率和产量,其中棉抗3种衣剂效果最好,在重度缺水时,出苗率、产量分别较对照不包衣处理提高317.9和20.6个百分点;中度缺水时,出苗率较不包衣处理提高153个和31.7个百分点.土壤NaCl含量0.4;、0.6;和0.8;,棉抗3田间出苗率分别对照高1.25、65.3和150个百分点.土壤NaCl含量在0.4;时对棉花产量影响不大;NaCl含量0.6;时,棉抗3比对照增产34.9;.
