摘要
土壤水分和氮肥用量是影响南疆盐渍化地区植物生长的重要因素。为明确不同灌水量和施氮量对南疆盐渍化地区棉花生长的影响,以中棉所43为研究对象,分别在3种灌水[高水(WH,4700m^3/hm^2)、中水(WM,4100m^3/hm^2)、低水(WL,3500m^3/hm^2)]和3种施氮[高氮(NH,360kg/hm^2)、中氮(NM,260kg/hm^2)、低氮(NL,160kg/hm^2)]处理下测定分析棉花的生长指标(株高、茎粗和叶面积)。结果表明:WHNM处理的棉花株高最高(73cm),棉花茎粗最粗(10.4mm);W_HN_H处理下,棉花叶面指数最大(4.8)。综合分析W_HN_M处理下棉花生长最佳。
Soil moisture and nitrogen fertilizer are important factors affecting plant growth in salinized areas of southern Xinjiang.In order to clarify the effects of different irrigation and nitrogen application rates on the growth of cotton in the salinized area of South Xinjiang,Zhongmian Institute 43 was selected as the research object,growth Indexes(plant height,stem diameter and leaf area)of cotton were measured and analyzed under three irrigation treatments:High Water(WH,4700 m^3/hm^2),medium water(WM,4100 m^3/hm^2),low water(WL,3500 m^3/hm^2),high nitrogen(NH,360 kg/hm^2),medium nitrogen(NM,260 kg/hm^2)and low nitrogen(NL,160 kg/hm^2).The results showed that under WHNM treatment,the height of cotton reached the highest 73 cm,the stem diameter was 10.4 mm under WHNM treatment,and the leaf index was 4.8 under WHNH treatment.Comprehensive Analysis showed that WHNM was the best treatment for cotton growth.
