在植物无土栽培过程中,如何保持营养液的适当浓度是无土栽培的重要环节。在营养液浓度不断升降的过程中,保持营养液的适当浓度,有下列三种方法: 1.补充水份,定期更换营养液:新栽的植物,无论是双层套盆或是单层盆,一次浇足营养液后,平时当水份消耗20％～30％后,浇水补充,夏天每2周、冬天每4周更换一次营养液。更换营养液前,将双层套盆内存的剩余营养液倒去,再将内盆或单层盆内基质用
In the process of plant soilless culture, how to maintain the proper concentration of nutrient solution is an important part of soilless culture. Nutrient concentration in the process of rising and maintaining the proper concentration of nutrient solution, the following three methods: 1. To add water, regular replacement of nutrient solution: New plant, whether it is double-sleeper or single basin Once poured enough nutrition solution, usually when the water consumption of 20% to 30%, watering supplement, summer every 2 weeks, winter every 4 weeks to replace the nutrient solution. Before changing the nutrient solution, the remaining nutrient solution in the double-sleeve tub is poured back, and then the internal tub or the single-layer tub matrix
