通过对近年新疆棉花区域试验中棉纤维品质表现优良的几个优质、抗病、早熟棉花新品种（系）的早熟性、丰产性、品质特性等性状进行进一步的比较鉴定,为这些棉花新品种（系）的审定和推广提供科学依据,以满足棉花生产对优质、抗病、早熟棉花品种（系）的需求。1材料和方法 参试品种（系）为29-1、中棉所36、16-1、豫棉 17优系 96-48（改种豫棉 15优系 9911）、豫棉15优系9907,以豫棉15优系9907为对照。试验地土质沙壤、前茬复播玉米、肥力中上等,灌溉方便,春灌（机井水灌）地。4月7日每公顷施尿素300kg+磷酸二铵 300kg做基肥,4月8日犁地,4月11日镇压、耙耱。棉种全部用0.3％敌克松+1.2％乙酰甲铵磷拌种,4月18～20日人工点播,机械覆膜。豫棉17优系96-48田块因烂种严重于4月 30日改种豫棉15优系9911。5月3～4日放苗、定苗、补
Through the comparative study on the characteristics of early maturity, high yield and quality of several high quality, disease-resistant and precocious cotton varieties (lines) with good cotton fiber quality in Xinjiang cotton regional trials in recent years, these new cotton varieties (Department) validation and promotion to provide a scientific basis to meet the cotton production of high quality, disease resistance, precocious cotton varieties (lines) needs. 1 Materials and methods The tested varieties (lines) were 29-1, Zhongmiansui 36,16-1, Yumai 17 Youyi 96-48 (Replanting Yumai 15 Youlian 9911), Yumai 15 Excellent System 9907, Yumai 15 excellent line 9907 as a control. Test soil sandy soils, pre-cropping corn, fertility in the upper, convenient irrigation, spring irrigation (irrigation wells). April 7 urea per hectare 300kg + diammonium phosphate 300kg to do basal fertilizer, April 8 plowing, April 11 crackdown, rake 耱. All kinds of cotton with 0.3% of the enemy grams of pine + 1.2% ammonium methyl phosphate seed dressing, April 18 to 20 artificial sowing, mechanical coating. Yu cotton 17 Department of 96-48 plots due to the serious rot on April 30 replanted Yu cotton 15 gifted 9911. May 3 to 4 Fangmiao, Dingmiao, fill
