摘要
以德美亚1号为供试材料,研究了3种不同氮肥对玉米生长的影响。结果表明:细胞酶活化缓释尿素处理叶绿素、干物质积累量均处于最高值,在完熟期比对照分别提高72.96%、55.33%,显著高于对照;缓释态尿素处理次之,叶绿素、干物质积累量比细胞酶活化缓释尿素处理分别低17.54%、6.66%;细胞酶活化缓释尿素处理农艺性状和经济性状均显著优于对照、普通尿素、缓释态尿素处理。综合分析认为,以施用细胞酶活化缓释尿素对促进玉米生长效果最佳。
Using Demeiya 1st as test materials, the test studied the effect of 3 kinds of nitrogen fertilizer on growth Zea mays. The results showed that chlorophyll, dry matter accumulation volume reached the highest value in the cell enzyme activators release state urea treatment, and were significantly higher than that of control by 72.96%, 55.33%, respectively, in ripe stage. Chlorophyll, dry matter accumulation volume of slow-release urea treatment were lower than that of cell enzyme activators release state urea treatment by 17.54%, 6.66%, respectively. Agronomic and economic traits of Z. mays treated by cell enzyme activators release state urea were significantly better than those treated by control, common urea and slow-release urea. Comprehensive analysis showed that cell enzyme activators release state urea promote the growth of Z. mays best.
