- 摘要:
- 以‘水果黄瓜A-B2’为试材，以植物诱导剂那氏齐齐发、叶面肥磷酸二氢钾喷施黄瓜苗叶片，以清水为对照，研究了植物诱导剂对黄瓜基质苗生长的影响，以期为培育优质黄瓜壮苗、提高壮苗指数、增加定植成活率提供参考依据。结果表明：喷施磷酸二氢钾和那氏齐齐发可有效控制黄瓜幼苗株高、叶长和叶宽，促进叶片数和茎粗的增加。黄瓜幼苗叶片数、茎粗和根长均以喷施磷酸二氢钾处理最大；黄瓜幼苗叶片SPAD值和氮含量则以喷施那氏齐齐发处理最高，均显著高于对照。喷施磷酸二氢钾和那氏齐齐发可抑制黄瓜幼苗地上部徒长，显著促进地下部生长，其中以喷施磷酸二氢钾处理最佳；根冠比和壮苗指数也以磷酸二氢钾处理最大。在黄瓜基质穴盘育苗生产中，喷施磷酸二氢钾可解决黄瓜幼苗徒长问题。
- 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.
