花生(花育16)地膜覆盖栽培的生长动态

对花生(花育16)地膜覆盖栽培、荚果产量在6 378.8 kg.hm-2水平下植株生长动态进行了研究。结果表明:根鲜重、叶鲜重及干重、叶面积以出苗后41~60 d增长最快;根干重、茎枝鲜重及干重、茎枝长度、主茎高度、果针鲜重与干重、荚果鲜重、荚果数、全株鲜重及干重均以出苗后61~80 d增长最快;荚果干重以出苗后81~100 d增长最快;出苗后1~80 d,植株生产的干物质主要分配在叶、茎枝中,此后逐渐转入以荚果为主。

A Study on the Growth Trend of the Film-Covered Peanut (Huayu16)

This is a study of the growth trend of a yield of filmcovered peanuts(Huayu16) in pods grown at 6378.8 kg/hm~2.The results showed that 41-60 days after emergence,the fresh weight of the root,the fresh and dry weight of the leaves,as well as the leaf area,increased fastest;61-80 days after emergence,the dry weight of the root increased fastest,so did the fresh and dry weight of the stems,the length of the stems,the height of the main stem,the fresh and dry weight of the fruit needle and needle handle,the fresh weight of the pod,the number of pods and the fresh and dry weight of the whole plant;81-100 days after emergence,the dry weight of the pod increased fastest.1-80 days after emergence,the distribution of the dry materials within the whole plant was mainly in leaves and stems,and then in the pod.
