Problems solved by technology

[0004] Although the tissue-cultured seedlings of Trigonum chinensis have a certain photosynthetic ability, they grow under high humidity, low light, low carbon dioxide, constant temperature, and heterotrophic conditions, and their adaptability is poor.
It is necessary to study its different growth and transplanting conditions to promote its tissue development and adapt to the external environment, especially the harsh environmental factors such as high salinity, strong temperature difference, and tidal erosion in Dongtan. The traditional transplanting method has poor operability and post-maintenance management. also extremely difficult

Abstract

The invention discloses a degradable seedling growing tray and a preparing method thereof. The degradable seedling growing tray is prepared from, by weight, 75-85 parts of deinked pulp, 50-60 parts ofplant fiber, 0.5-1 part of straw leavening agent, 22-24 parts of modified starch, 4-6 parts of binder, 1-1.5 parts of releasing agent, 4-6 parts of nutritional agent, 0.8-1.2 parts of antibacterial agent, and 3-5 parts of waterproof thin film. The degradable seedling growing tray has a certain effect of resisting saline-alkaline decomposition, is isolated from the outside in a seedling adaptationperiod, and has degradability, after seedlings are adapted to a saltmarsh environment, root systems of the seedlings can penetrate through a hole tray, and finally the degradable seedling growing tray is completely decomposed. According to the degradable seedling growing tray and the preparing method thereof, the survival rate of tissue culture seedlings after transplanting is increased, and thetransplanting cost is lowered.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a degradable seedling raising tray and a preparation method thereof. Background technique [0002] Sea trigonum is a perennial herbaceous plant of Cyperaceae, which is mainly distributed in the salt marshes of the Yangtze River Estuary and Hangzhou Bay. Once gone, the ecosystem collapses. [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 effective means to protect their planting resources. [0004] Although the tissue-cultured seedlings of Trigonum chinensis have certain photosynthetic ability, they grow under the conditions of high humidity, low lig...
