摘要: 【目的】 研究水、盐、温及其交互作用等环境因子对无膜滴灌棉种中棉619萌发特性的影响。【方法】 基于正交试验、隶属函数法及聚类分析,以PEG模拟干旱胁迫、NaCl模拟土壤盐分胁迫及用生化培养箱控制环境温度,对比分析水、盐、温及其交互作用对无膜滴灌棉种中棉619(无膜棉)和膜下滴灌棉种新陆中37号2个棉种萌发特性的影响。【结果】 两者均对温度有较高的要求,而无膜滴灌棉种耐盐及抗旱性优于膜下滴灌棉种,其中温度对于种子萌发的影响达到极显著水平(P<0.01),盐分达到显著水平(P<0.05),而水分及交互作用未达到显著水平。【结论】 适宜无膜滴灌棉种中棉619环境因子范围是温度为25℃,盐分为0.1%~0.4%,水分为7.5%和15%,当水分含量为15%、盐分含量为0.2%及温度为25℃时,无膜滴灌棉种的萌发效果最好。

Abstract: 【Objective】 To study the effects of water, salt, temperature and interaction on the germination characteristics of Zhongmian 619 cottond.【Methods】 Based on orthogonal experiments, membership function method, and cluster analysis, PEG simulates drought stress, NaCl simulates soil salt stress, and a biochemical incubator were used to control the environmental temperature.The effects of water, salt, temperature and their interactions on filmless drip irrigation were compared and analyzed.After that, effects of germination characteristics on cotton cultivar Zhongmian 619 (filmless cotton) and Xinluzhong 37 cotton cultivar Xinluzhong under drip irrigation were compared.【Results】 The results show that: Both had higher requirements for temperature, and the salt tolerance and drought resistance of cotton seeds without film and drip irrigation were better than those under drip irrigation.The effect of temperature on seed germination reached a significant level (P <0.01), the salinity reached a significant level (P <0.05), but the moisture and interactions did not reach a significant level.【Conclusion】 Therefore, the suitable environmental factors for Zhongmian 619 cotton with no film drip irrigation are temperature 25℃, salt content 0.1%-0.4%, water content 7.5% and 15%, when water content is 15%, salt content is 0.2% and temperature is 25℃, the germination of the filmless cotton seed without drip irrigation was the best.
