| 摘 要： | 采用营养钵称质量的方法,研究补充80%、100%、120%蒸发量的不同灌溉量对番茄幼苗形态、干物质积累、水分生理等的影响。结果表明,按植株蒸腾蒸发量的100%补充灌溉,番茄幼苗的株高、茎粗、叶片数达最大值,且植株干物质积累增大,壮苗指数显著提高。因此认为番茄苗期最佳补充灌溉量为植株蒸腾蒸发量的100%。

| Abstract: | The nutritional pots of tomato seedlings were weighed to study the effects of different supplement 80% ET0,100% ET0,120% ET0 on plant shape,dry matter accumulation and water physiological of tomato seedlings.The results showed that,under supplement irrigation 100%ET0,the plant height,stem diameter,and leaf number were up to the maximum,with increased dry matter accumulation and significantly increased lusty seedling index.So it was concluded that the 100% ET0 supplementary irrigation was the best for the gr... |
