摘要
为确定硝酸铵与有机肥配施对草坪草早熟禾坪用质量与生长发育的影响规律,明确适合与硝酸铵配施的有机肥种类,于田间条件下,设置ck(T1)、施用硝酸铵(T2)、施用硝酸铵+发酵饼肥(T3)、施用硝酸铵+腐殖酸复混肥(T4)等4个处理,3次重复,进行了早熟禾施用硝酸铵与有机肥配施试验。结果表明:分蘖密度方面,6~10月,T3处理与T1处理相比显著提高了早熟禾分蘖密度,10月10日的分蘖密度显著高于T4处理的。盖度方面,6月、8月、10月的测定结果中,T3处理的盖度处于最高值;7月、9月,T3处理与T2处理之间无显著差异。株高、叶长方面,7月10日,T3处理的均显著高于T2处理和T4处理的,8月、9月T3处理与T2处理之间无显著差异,6~10月T3处理的叶片长度均显著高于T4处理的。叶片宽度方面,10月10日,T3处理的显著高于T4处理的,其余测定月份T3处理与T4处理之间无显著差异。叶绿素的质量分数方面,8月10日,T3处理的显著高于T2处理的,6~8月、10月T3处理的与T4处理的之间无显著差异。综合分析认为,硝酸铵配施有机肥在部分月份有利于早熟禾生长,提高坪用质量。
The effect of application of ammonium nitrate and organic fertilizer on the quality and growth of Poa pratensis L.was studied,and the type of organic fertilizer suitable for combination with ammonium nitrate was determined,to provide theoretical basis for the scientific and reasonable application of organic fertilizer in lawn maintenance.Under the field conditions,4 treatment by control(T1),ammonium nitrate(T2),ammonium nitrate+fermented cake fertilizer(T3),ammonium nitrate+humic acid compound fertilizer(T4)were set,and repeated three times.The results showed that:from June to October,the Poa pratensis L.density of T3 was significantly increased than T4,T3 was significantly higher than T4 in October 10th;the coverage of T3 was the highest in June,August and October,and there was no significant difference between T3 and T2 in July and September;the plant height and leaf length of T3 were significantly higher than T2 and T4 when in July 10,and it was no significant difference between T3 and T2 from August to September,the leaf length of T3 was significantly higher than T4 from June to October;the leaf width of T3 was significantly higher than T4 in October 10th.There was no significant difference between T3 and T4 in other measurement months;the chlorophyll content of T3 was significantly higher than that of T2 in August 10th,and there was no significant difference between T3 and T4 in June,July,August and October.The comprehensive analysis showed that ammonium nitrate combined with organic fertilizer was beneficial to the growth of Poa pratensis L.in some months and improved the quality of lawn.
