摘要
2007年对绥农22大豆品种进行不同密度对产量及品质影响的研究。结果表明：株高随密度增加而升高,茎粗和分枝数随密度增加而减少。在一定密度范围内百粒重随密度增加而升高,单株荚数随密度的增加而降低;密度在5万-35万株.hm-2范围内,单位面积的荚数、粒数和产量均随密度增加而增加。密度为5万-30万株.hm-2时,脂肪含量随密度增加而升高,蛋白质含量随密度增加而降低;密度超过30万株.hm-2后,蛋白质含量开始上升。单株产量、单株荚数、单株粒数、节数、茎粗、分枝数、蛋白质含量、蛋脂总含量与密度呈极显著负相关;每平方米荚数、每平方米粒数、百粒重、株高与密度呈极显著正相关;脂肪含量与密度呈显著正相关;产量与每平方米荚数、每平方米粒数呈极显著正相关。因此确定,绥农22的适宜密度范围在30万-35万株.hm-2。
The effect ofdifferent density on yield and quality of Soybean varieties of Suinong 22 was studied in 2007.The results indicated that in a certain extent,the 100-grain weight was increased and the pots per plant were decreased with the increasing of the density in a certain extent.When the density between 50 000 and 350 000 plant per hectare,the pot number,grain number were increased with the increasing of the density.With the increasing of density,when the density between 50 000 and 300 000 plant per hectare,the oil concentrate was increased and the protein concentrate was decreased with the increasing of the density,when the density over 300 000 plant per hectare,the concentrate of protein was increased.Plant yield,pot number per plant,seed number per plant,node number,stem diameter,branches number,protein content and oil content were all significant negative correlation with the density.Pot number per square meter,seed number per square meter,100-grain weight,plant height were significant positive correlation.Oil content and density was positive correlation,yield with pot per square meter,seed number per square meter was significant positive correlation.So,the suitable density for Suinong 22 was between 300 000 and 350 000 plant per hectare.
