| 摘 要： | 通过2年的温室小区番茄栽培试验,研究了覆膜滴灌条件下滴灌追肥和刨穴追肥对番茄土壤水分利用率和产量的影响。结果表明,不同追肥方式对番茄产量有较大影响,滴灌追肥可以显著地增加番茄产量、提高水分利用效率。并从田间土壤水分时空变化、土壤养分有效性方面分析了引起差异的可能原因。

| Abstract: | The effect of different method of top dressings of drip fertilization and hole fertilization on tomato yield and water use efficiency were studied under drip irrigation of plastic sheeting through 2-year field contrast experiment in greenhouse. The result shows that different method of top dressing affected tomato yield with very significance level, and top dressing of drip fertilization increases tomato yield and water use efficiency significantly. And the probable reason of difference was analyzed through temporal and spatial variation of soil profile water and soil nutrient availability. |
