Abstract:: ‘Fruit cucumber A-B2’ was used as test material，effects of plant inducer on growth of cucumber matrix plug seedling were studied by spraying plant inducer Nashiqiqifa，or foliar fertilizer potassium dihydrogen phosphate and water was control，in order to cultivate high-quality and robust cucumber seedling，improve the number of strong seedling and increase the survival rate of engraftment.The results showed that potassium dihydrogen phosphate and Nashiqiqifa could effectively control the plant height，leaf length and width，promote the increase of leaf number and stem diameter.Leaf number，stem diameter and root length by spraying potassium dihydrogen phosphate were the largest.The leaf SPAD value and nitrogen content by spraying Nashiqiqifa were significantly higher than control.Aboveground production rate of cucumber seedlings by spraying potassium dihydrogen phosphate and Nashiqiqifa was inhibited，the underground growth of cucumber seedling was significantly promoted，but potassium dihydrogen phosphate was the best.Root-shoot ratio and strong seedling index were also the largest by spraying potassium dihydrogen phosphate.Therefore，potassium dihydrogen phosphate and Nashiqiqifa could be used in production of cucumber matrix plug seedling，to solve the excessive growth problems of cucumber matrix plug seedling.
