Embodiment 1

[0021] In order to test the mechanical strength, degradation rate and the optimum time for hardening and transplanting of tissue cultured seedlings, 8 degradable seedling-raising plugs were produced, weighed and placed in Chongming Dongtan Reclamation Area to test their degradation rate. Observe its appearance and structure every 2 days, and record its disintegration time. After 50 days, most of the 8 kinds of plugs were degraded, and their main shapes and structures were completely disintegrated. Take the tray back to the laboratory, wash, dry, and weigh. The degradation rate is shown in the table below. (The following adhesives were purchased from Taian Qineng Chemical Technology Co., Ltd., the model is qn)

[0022]

[0023] A kind of preparation method of above-mentioned degradable seedling-raising plug tray, comprises the following steps:

[0024] 1) take each component according to mass ratio;

[0025] 2) Dry each plant fiber raw material at 60-85°C, and then crush...

Abstract

The invention provides a degradable seedling raising holed tray.The degradable seedling raising holed tray is prepared from deinked pulp, plant fiber and an adhesive, wherein the mass ratio of the deinked pulp to the plant fiber to the adhesive is 60-80 to 20-40 to 0-2, and the plant fiber is selected from one or more of straw, bamboo reeds, reeds and wheat straw.The invention further provides a preparation method of the degradable seedling raising holed tray.Firstly, plant fiber raw materials are dried and then are smashed to reach 40-70 mesh; the deinked pulp, the plant fiber and the adhesive are mixed according to the mass ratio, are evenly stirred and are charged into a mold, pressing, molding and mold release are performed, and then drying is performed to reach 10-20% of water content, namely the finished product degradable seedling raising holed tray is obtained.The degradable seedling raising holed tray has a certain saline-alkaline resisting and decomposing role, is isolated from the outside at a seedling adapting stage and also has degradability, root systems can grow to penetrate through the holed tray after seedlings adapt to a salt marsh environment, and finally complete degradation is achieved.The degradable seedling raising holed tray improves the survival rate of transplanted tissue cultured seedlings and reduces the transplanting cost.

Description

technical field [0001] The invention belongs to the field of biology and relates to a seedling raising device, in particular to a degradable seedling raising tray and a preparation method thereof. Background technique [0002] Scirpus marique ter Tang&F.T.Wang is a perennial herb of Cyperaceae Scirpus genus. It is mainly distributed in the salt marshes of the Yangtze River Estuary and Hangzhou Bay. Once the key species in the ecosystem disappear, the ecosystem will collapse (Chen Xiuzhi, Sun Ying. 2011. The current situation and protection and utilization of the unique salt marsh plant in China-S. :60-63.). [0003] In view of the importance of Trichosanthus in the wetland ecosystem of the Yangtze River Estuary and the threats it is currently facing, we must strengthen the research and protection of this species. Through tissue culture and other artificial means, it can be reconstructed and rejuvenated. The community of indigenous species such as weed grass is one of the e...
