摘要: 为明确番茄穴盘育苗基质适宜养分添加量,以番茄品种中杂105为试材,3:1:1(V/V/V)草炭、蛭石和珍珠岩为育苗基质,研究了基质养分添加量对番茄穴盘苗生长发育及成苗质量的影响,测定了种子出苗率、基质速效养分含量变化趋势及幼苗形态指标等。随基质养分添加量的升高,番茄幼苗根区基质养分含量呈增加趋势,番茄种子出苗率、幼苗壮苗指数呈先升高后降低的趋势。总的来说,基质养分添加量为600N-120P-600K时,培育的番茄穴盘苗质量较优,表现为出苗率升高、壮苗指数增加,分别比其他处理提高了18.54%~22.60%,2.07%~147.79%。

Abstract: The effects of nutrient addition in substrate before sowing on growth and quality of seedling were studied with tomato Zhongza No.105,3:1:1(V/V/V) peat,vermiculite,and perlite were used as substrate,emergence rate,available N,P,and K content in substrate and morphological index of tomato plug seedlings were determined.Nutrient content of substrate in root zone increased with the elevation of nutrient addition in substrate,while emergence rate and vigor index of tomato seedling increased at first and decreased subsequently.A better addition of nutrient in substrate before sowing was 600N-120P-600K,emergence rate and vigor index were higher than other treatments by 18.54%-22.60%,2.07%-147.79%.

Key words: Tomato, Plug seedlings, Addition quantity, Quality of seedling
