The sowing date experiment obtained following results.( i) From April 25 to May 25,with the delay of the sowing date,the main stem height,the number of branches per plant,the number of pods per plant,full-seed pod rate and the yield decreased in Dongming test site,while the sowing date had little effect on the double-seed pod rate,and the best sowing date was April 25;in Wendeng test site,with the delay of the sowing date,the main agronomic traits and yield were firstly increased and then decreased,the yield was highest on May 10,followed by May 5 and April 30,the difference between the three treatments was not significant,and the appropriate sowing date was from April 30 to May 10,and the best sowing data was May 5.( ii) In the range of 90 000-210 000 holes/ha,with the increase of the density,the main stem height,lateral branch length and the number of pods per plant showed a decline trend,the density had little effect on the number of branches per plant,and the double-seed pod rate was the highest at 120 000 holes/ha,the yield and full-seed pod rate were the highest at 150 000 holes/ha,so the optimum density was 150 000 holes/ha.展开更多
