- 摘要:
- S.B技术是集种子处理、施肥、掐尖于一体综合生产技术,为分析各项处理的增产作用,选择大豆品种吉育47,对S.B技术增产效应进行分析。结果表明:S.B种子处理、S.B施肥、掐尖都有增产作用,S.B施肥增产达极显著水平,S.B种子处理、掐尖增产均达显著水平。大豆最高产量为S.B种子处理、S.B施肥和第二片复叶掐尖处理组合;S.B技术最佳密度为15万株.hm-2。由于掐尖后大豆植株多数形成双茎株,平均茎粗变细,抗倒能力变差,所以掐尖处理应慎用。
- Abstract:
- S.B technology is a comprehensive production technology with seed treatment,fertilization and removing growing point.The yield-increasing effect of S.B technology was analyzed with soybean Jiyu 47 as materal.Results showed S.B seed treatment increased seed weight;S.B fertilization increased plant height,pod number and seed weight;removing growing point increased branch number and pod number,so the three individual technology all increased soybean yield significantly.The best treatment combination for the highest yield was:S.B seed treatment,S.B fertilization and removing growing point of the second compound leaf. The optimum density of S.B technology was 1.5×10-5plants per hectare.Although had obvious yield-increasing effect,removing growing point could form double-stem plants,weaken stem diameter and lodging resistance Removing growing point should be carefully used.
