无土栽培营养液对番茄产量和品质的影响

Effects of Nutrient Solution on Yield and Quality of Tomato under Soilless Culture

为了降低番茄筋腐病病果率,设计了5种营养液配方,研究不同营养液组成对无土栽培条件下"144"番茄筋腐病、产量和质量的影响。结果表明,番茄的筋腐病与营养液的氮钾比呈正相关,与营养液中的氨态氮与总氮比例呈正相关。在无土栽培中要注意适当调节氮钾比和氨态氮与总氮的比例。

In order to reduce the diseased fruit rate from rotten flesh disease in tomato, five nutrient formulae were designed to research the effects of different nutrient formulae compositions on yield and quality of ＂ 114＂ tomato＇s rotten flesh disease under soilless culture. The results showed that there was positive correlation between tomato＇s rotten flesh disease and the ratio of nitrogen to potassium, and the ratio of ammonia nitrogen to total nitrogen. In soilless culture, we should pay attention to proper adjust the ratio of nitrogen to potassium and the ratio of ammonia nitrogen to total nitrogen.
