基于不同生物炭添加量和灌水定额对番茄生长发育的影响

The Effects of Different Biochar Supplemental Amount and Irrigation Quota on Tomato Growth and Development

通过田间试验,研究不同生物炭添加量与灌水定额对番茄生长的影响,为合理确定温室大棚内番茄生长所需最佳生物炭添加量与灌水定额提供依据。试验设置7个不同的处理,测量温室大棚盆栽番茄从苗期到开花坐果期的株高与茎粗。试验结果表明:①120 g生物炭/ET、600 g生物炭/ET处理番茄的株高与茎粗均呈现高增长率;360 g生物炭/0.8ET、360 g生物炭/ET处理番茄的茎粗呈现高增长率,但是株高增长率不算高;600 g生物炭/0.8ET处理与其他处理相比,番茄的株高与茎粗均呈现较低增长率。②各处理之间的显著性P=1.00>0.05,即各组茎粗与株高无显著性差异。

Field experiments were conducted to study the effects of different biochar supplemental amount and irrigation quota on tomato growth,and to provide a basis for reasonably determining the optimal biochar supplemental amount and irrigation quota for tomato growth in greenhouse.Plant height and stem diameter of tomato potted in greenhouse from seedling stage to flowering and fruit-setting stage were measured under 7 different treatments.The results show that①the plant height and stem diameter of tomato treated with 120 g biochar/ET and 600 g biochar/ET both showed a high growth rate;360 g biochar/0.8ET and 360 g biochar/ET showed a high growth rate of stem diameter,but the growth rate of plant height was not high.Compared with other treatments,the plant height and stem diameter of tomato treated with 600 g biochar/0.8ET showed a lower growth rate.②Significant P=1.000>0.05,that is,there was no significant difference in stem diameter and plant height among all treatments.
