番茄树型栽培营养及植株调控试验

Experiment on Nutrition and Plant Style of Tomato Tree Type

为实现番茄的单株高产,达到番茄最佳"树型",以及高品质和高观赏价值,针对番茄"树"不同生育期进行营养、水分供给调控,以期确定番茄"树"不同生育时期的最适营养、水分供给方案。结果表明,应用营养液1(7.50 mmol/LNO3-,0.46 mmol/L NH22-,0.665 mmol/L PO43-,4.165 mmol/L K+,2 mmol/L Ca2+)栽培的番茄"树"生长健壮、树型调控理想,番茄果实综合品质较好,单果质量、产量较高。

We use different nutrient solution formulations to achieve high yield of tomato single plant and ornamental value through controlling nutrition supply and plant style for different growth stages.The result showed that tomato ＂tree＂ not only turned to strong growth and good style,but also had better quality and higher yield of single plant by using nutrient solution 1 which contained 7.50 mmol/L NO3-,0.46 mmol/L NH22-,0.665 mmol/L PO43-,4.165 mmol/L K＋ and 2 mmol/L Ca2＋.
