摘要:

【目的】 研究有机液体肥对新疆南疆膜下滴灌棉花冠层特征、产量和品质的影响。【方法】 选用塔河2号为参试品种,以单施化肥棉田为对照(CK),设置有机液体肥处理(T1、T2、T3、T4、T5),测定并分析不同处理下株高、主茎叶片数、叶面积指数、叶倾角、产量和品质的变化。【结果】 与CK相比,施用有机液体肥提高了棉花株高、主茎叶片数、叶面积指数、叶倾角与地上部生物量。当籽棉产量达到6 000 kg/hm2以上时,棉花株高、主茎叶片数、叶面积指数和叶倾角较CK分别增加1.3~10.3 cm、2.0~2.3片、1.7~2.9、5.6~9.3°,营养和生殖器官干物质重较CK分别增加了1.3~25.7和0.1~44.5 g/株。且当籽棉产量超过6 000 kg/hm2时,籽棉产量、单铃重、总铃数较CK分别增加了17.2%~31.9%、15.5%~28.8%和3.5%~10.1%。此外,与CK相比,施用有机液体肥还提高了棉花上半部纤维平均长度、整齐度和断裂比强度。【结论】 与单施化肥相比,施用有机液体肥能够改善棉花冠层结构,促进干物质积累,增产提质,且成本低,易操作,适合新疆南疆棉区推广应用。

Abstract:

【Objective】 To ascertain the effects of organic liquid fertilizer on canopy characteristics,yield and quality of cotton under membrane drip irrigation in southern Xinjiang.【Methods】 Tahe No.2 was selected as the test variety,and the cotton field with single fertilizer application was used as the control(CK).Organic liquid fertilizer treatment(carried out in the five fields of T1,T2,T3,T4 and T5) was set.The changes of plant height,main stem and leaf number,leaf area index,leaf dip angle,yield and quality under different treatments were measured and analyzed.【Results】 Compared with CK,the application of organic liquid fertilizer increased plant height,leaf number,leaf area index,leaf inclination and aboveground biomass of cotton.When the seed cotton yield reached 6,000 kg/hm2,plant height,leaf number of main stem,leaf area index and leaf inclination angle increased by 1.3-10.3 cm,2.0-2.3,1.7-2.9 and 5.6-9.3° compared with CK,respectively.Compared with CK,the dry matter weight of nutrition and reproductive organs increased by 1.3-25.7 g/plant and 0.1-44.5 g/plant,respectively.When the seed cotton yield exceeded 6,000 kg/hm2,the seed cotton yield,single boll weight and total boll number increased by 17.2%-31.9%,15.5%-28.8% and 3.5%-10.1% compared with CK,respectively.In addition,compared with CK,the average length,uniformity and breaking strength of the top half of cotton were improved by applying organic liquid fertilizer.【Conclusion】 Compared with single application of chemical fertilizer,the application of organic liquid fertilizer can improve cotton canopy structure,promote dry matter accumulation,increase yield and improve quality with low cost and easy operation,which is suitable for popularization and application in cotton area in southern Xinjiang.
