DCPTA与CCC复配对寒地春玉米根系生长及茎秆农艺性状的影响
Effects of Mixed Compound of DCPTA and CCC on Root Growth and Stem Agronomic Traits of Spring Maize in Cold Area
摘要
Abstract
In order to clarify the effects of mixed compound of DCPTA and CCC on root growth and stem agro-nomic traits of spring maize. In the experiment,Fenghe 1 was chosen as the experimental material,The mixtures be sprayed on maize in the 6-leaf stage,and the water as contrast. The data be respectively measured after 2,4,6,8,10 days of spraying. The results showed that after spraying mixtures,compared with the contrast,root volume,root sur-face area,root length and plant root dry weight are increased. The root surface area and root length were significant difference between the treatment and the contrast. The largest increased rate of former is appearing in the second day after spraying and the latter is sixth day,The data respectively are 49. 16% and 58. 20%. Compared with contrast,the diameter of section between stem is increased and the length of section between stem reduced,but difference is not significant. Compared with the contrast,unit dry weight of stem length and percentage of dry matter are increased. The largest increased rate is appearing in the fifth day after spraying. The data respectively are 5. 99%,7. 99%. The test provide theoretical and experimental basis for the mixtures of DCPTA and CCC applied to maize production.关键词
