All the photoperiodic treatments conducted at flowering, podding, filling stages had significant effect on the chemical compositions of soybean seeds. 开花期、结荚期和鼓粒期的光照处理均对大豆化学品质有影响。
OF increased dry matter accumulation of soybean stems in podding and pod filling stages as well, which is important in improve the lodging resistance of soybean. 优化施肥提高了结荚期、鼓粒期大豆茎秆干物质的积累量,这在一定程度上对提高大豆抗倒伏能力具有重要作用。
Content of neutral detergent fiber ( NDF) and acid detergent fiber ( ADF) in dry matter increased gradually from 42.59%, 32.03% at the seedling stage to 61.50%, 46.68% at the podding stage, respectively; 随着茎叶干物质的增长,干物质中中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量逐渐增加,分别由苗期的42.59%和32.03%升至成熟期的61.50%和46.68%;
The results show that successive cropping have a slight effect on plant height, branch number, and node number of soybean varieties. Successive cropping have a significant effect on height of podding of soybean varieties. 结果表明:重茬对大豆株高、分枝数和主茎节数的影响与正茬相比均不显著,重茬能显著增加大豆的结荚高度。
The content of soil water stable aggregates reaches the maximum value during soybean blooming and podding stage, which is 31.7% higher than it's seedling stage. 在大豆盛花期和结荚期,土壤水稳性团聚体数量达到最大值,比苗期增加30%。
The photoperiodic induction not only controlled flowering, but podding and maturing also. 4. The evolutionary tendency of photoperiodic induction from wild soybean to cultivated ones was discussed. 大豆光周期效应不仅制约开花,且制约能否结荚与成熟,(4)讨论了由野生大豆进化为栽培大豆光周期效应特性的变化趋向。
According to the rate of yield loss of soybean, control costs and so on, the control index of B. similaris at flowering and podding stage of autumn soybean was put forward as follows: 20 adults per 100 plants or 0.15 newly-injured young pod per plant. 根据大豆产量损失率及防治费用等制订了花荚期秋大豆同型巴蜗牛的防治指标:每百株20头成贝,或者每株新被害幼荚0.15个。
Photosynthetic rate and source sink manipulation effects on podding characteristic in soybean 大豆产量形成期光合速率和库源调节效应
The results indicated that segment of the ground of White Mustard had different water defect sensitivity in different stage, the first sensitivity in flowering stage, the second in podding formation stage, the third in budded term. 结果表明,白芥在不同生育时期对水分亏缺敏感性不同,开花期最为敏感,其次为结荚期,蕾苔期最不敏感。
Meanwhile drought stress decreased the dry substances accumulation of later growth phases, severe stress and moderate stress had relatively higher dry substances accumulation at flourished flowering and early podding respectively. 并且干旱胁迫均降低生育后期的干物质积累,严重胁迫及中度胁迫分别在开花盛期、结荚初期具有相对较高的干物质积累。
In indeterminate podding habit varieties, 53.1% of whitefly nymphs were present on from the 11th leaves to 16th leaves; 无限结荚习性品种主要分布在中上部,第11叶至第16叶上烟粉虱数占单株烟粉虱总数的53.1%;
In contrast with it, the soil cellulolytic enzyme activity of podding stage is the highest in soybean following soybean for 2 years and it is almost higher podding stage than that of sowing time, mature period. 而结荚期酶活性则以连作二年酶活性最高,出现了与播期、成熟期截然不同的变化趋势,结荚期酶活性几乎都高于播期、成熟期。
From flowering stage to podding period, the dynamic change of root-soil interface soil urease activity shows "V"-shaped trend, soil enzyme activity increased gradually before podding period, which reached the highest up to podding period and reduced gradually at maturity. 盛花期至成熟期,根面土壤脲酶活性的动态变化呈倒V状的变化趋势,即为结荚期以前土壤酶活性逐渐升高,结荚期酶活性值最大,成熟期逐渐降低。
