摘要
以散叶生菜“203”为试材,采用上海孙桥配方营养液,研究了适宜温度(25~30℃)和高温(30~40℃)条件下,4种不同剂量(0.5倍剂量、孙桥配方标准剂量、1.5倍剂量和2倍剂量)处理对生菜生长及品质的影响。结果表明:在高温、营养液1.5倍剂量时,生菜的株高、茎粗、植株的干鲜重等达最大值,在维生素C、可溶性蛋白、可溶性糖等方面也优于其它处理。在适宜温度下,使用孙桥配方标准剂量,生菜生长和品质表现最好。
To investigate the effects of nutrient solution formulations on the growth and quality of loose leaf lettuce"203".The authors performed experiment on four kinds of different doses(Sunqiao formula standard dose,1.5 times the dose,2 times the dose and 0.5 times the dose) and two kinds of temperature: the appropriate temperature(25~30℃) and high temperature(30~40℃).The results showed that under the condition of the high temperature,when at the dose 1.5 times, , the growth treats of lettuce such as stem diameter, plant dry and fresh weight were much better than others,it was also superior to other treatment in vitamin C, soluble protein and soluble sugar, when at the appropriate tempera ture, the growth and quality of lettuce showed the best performance on condition of standard-dose formulations of Sunqiao.
