植物体内的营养状态与生长有关,当植物体内营养浓度达临界浓度以下,若不及时采取措施,必然影响生长及产量,通过植物组织分析,了解营养元素在植物组织内的浓度,确定与良好生长和高产有关的叶片养分标准,可为合理施肥提供依据。 一、材料与方法 试验用番茄品种为“佛洛雷德”(种
Plant vegetative state and growth, when the plant nutrient concentration below the critical concentration, if not promptly take measures that will inevitably affect the growth and yield, plant tissue analysis to understand the concentration of nutrients in plant tissues to determine and good growth And high-yield-related leaf nutrient standards, can provide a basis for rational fertilization. First, the material and method of test Tomato varieties as “Florelde” (species
