Investigation On Key Cultivation Techniques Of Medicinal Forsythia Suspense In Taihang Mountain Of Hebei

Forsythia suspense (Thunb.) Vahl belongs to Oleaceae. It has many effects for disease, and is agood material. Forsythia is usually planted in the wild, especially in Taihang Mountain have a certainarea of wild Forsythia forest. Forsythia natural tree growth disorders, seed setting rate is extremely low,the nut size difference is very big, the quality of medicinal materials is poor, not suitable for therequirements of the quality of medicinal materials. In recent years, along with the returningfarmland to forests, and the implementation of forestry greening projects around Beijingand Tanjin. In Hebei Taihang Mountain has planted a large area of Forsythia medicinalforest. But due to the biological characteristics, growth and development regularity andmanagement, ect, are lack of system’s technology. In production reveals that tree isdisorder, seed setting rate is low, don’t understand management and allow the growth, ect.Which has a serious impact on the farmers’ income. So carrying out research onconstruction and management technology of Forsythia forest, to guide Forsythiaproduction is very important.The main results are as follows:1.Seedlings technology is mainly divided into the health seedling, cutting seedlingand container seedling. Comprehensive introduction to three kinds of seedling cultivation,you can see from seedling, the seed sprouting ability must be carried out in the germinationand the management cycle is long, so that outplanted has a long time. Easy cuttingseedlings, can show a large supply of good seedling production in a relatively short period,so be widely adopted. In the local most innovative is that the container seedling techniquehas been applied to the forsythia seedling. Such management is more convenient, thebreeding period is shortened, and also local materials cost is not high. Combined with thebasic situation of the local, this papes argues that Jingxing container seedling technology ismore technical.2.Tending management adopts rainwater collection storage system, in the lack ofrain of the Taihang Mountain, no doubt is a technique worthy of popularizing. In thepruning, adopting the method of similar to the three sets of branches, to set up the oldtree heavy cutting, wintry light cutting, formation of dry natural form more than the trunk open alone heart-shaped clip plastic technology system. This is to keep good tree, and thekey technology of control of its growing. Established pest control technology, the optimumharvesting time and better processing method. In late July and early September is not fullymature green fruit picking, the green become warped the best harvest time, at the end ofSeptember to pick ripe yellow fruits, green up using steam for15min after work best todry, higher than natural air contents forsythia.3.As can be seen in the results and analysis,15g diammonium phosphate andspraying800times solution of potassium dihydrogen phosphate,has a certain impact onforsythia fruit-set rate production, compared with the control, fruit and thousand-seedweight difference is very significant. Fertilizer and no fertilizer forsythia glycosidescontent are significant difference.
