Background
Cyclocarya paliurus [ Cyclocaraya paliurus (Batal.) Iljinskaja ] also named Cyclocarya paliurus, Cyclocarya paliurus and the like is a plant of Cyclocarya of Juglandaceae (Juglandaceae) of Dicotyledoneae (Dicotyledoneae). It is a unique single-species plant in China, is one of the essential protected endangered plants in China, and belongs to three protective plants. When the cyclocarya paliurus is used for cultivating the seeding in the field in the open, the seeds have deep dormancy characteristic, the germination rate of the field nursery is low, the average germination time is long, the seedling emergence period lasts for 2-5 months, the seedling emergence is irregular, the seedling growth is uneven, the quality difference of the seedlings is large, the number of the first-class seedlings is only 12.7 percent, the number of the qualified seedlings is only 61.4 percent, meanwhile, when the cyclocarya paliurus is used for afforestation by utilizing the traditional bare-rooted seedlings cultivated in the field, the seedling recovery period is long and the afforestation survival rate is low because the lateral roots and the fibrous roots are few, meanwhile, due to the large quality difference of the seedlings, the serious differentiation of the seedlings, the low afforestation preservation rate and the poor forest phase in the young forest period, the cultivation and the industrialized development of the cyclocarya paliurus artificial forest resources are seriously influenced, therefore, with the rapid development of the cyclocarya paliurus industry, in order to improve the seedling quality of cyclocarya paliurus, seedling container seedling afforestation is gradually used in artificial forest resource cultivation.
Seedling raising containers used in the current market are mainly classified into two categories: the container that can plant the income soil and the container that can not plant the income soil, the first kind of container can plant the income soil with the nursery stock together, including various paper nutrition cups, this kind of container of non-woven fabrics can degrade in soil, but easy breakage in the use, be difficult for the transport, and short service life, and the non-woven fabrics container is because the non-woven fabrics material is thin, and the hole is big, causes nursery stock and the matrix water loss of growing seedlings too fast, in time moisturizing, the seedling raising in-process, the irrigation water consumption is big, and water can flow out from the non-woven fabrics space moreover, causes the moisture waste.
