不同用量增效尿素对棉花农艺性状及产量的影响
|
摘要
为提高棉花产量,提升纤维品质,以新陆中57号为材料,研究不同用量增效尿素对棉花农艺性状及产量的影响。结果表明,随着增效尿素用量的增加,棉花株高、茎粗、果枝数和铃数均呈现先升高后降低的趋势,在施用增效尿素525 kg/hm2时达到最大值;叶绿素含量(SPAD值)在不同时期呈现先升高后降低的趋势,花期达到峰值;产量性状方面,在施用增效尿素525 kg/hm2时,单铃重和衣分最大;纤维品质方面,施用增效尿素525 kg/hm2处理长度、整齐度、成熟度最好。由此说明,增效尿素适宜用量为525 kg/hm2,可达到高产提质的效果。
In order to improve the yield and fiber quality of cotton,Xinluzhong 57 was used as material to study the effect of different application rates of synergistic urea on cotton agronomic characteristics and yield. The results showed that with the increase of application rates of synergistic urea,the plant height,stem diameter,fruit branch number and boll number showed a trend of increasing first and then decreasing,and reached the maximum under the treatment of synergistic urea 525 kg/hm2. The SPAD values showed a trend of increasing first and then decreasing in different periods,and reached the peak in the flowering period. Under the treatment of synergistic urea 525 kg/hm2,the single boll weight and clothing percentage were the largest on yield characteristics;the length,uniformity and maturity were the best on fiber quality. In conclusion,the appropriate application rate of synergistic urea is 525 kg/hm2,it can achieve the effect of high yield and quality improvement.
