Degradable plant fiber paddy seedling cultivation disk and preparation method thereof

Abstract

The invention provides a degradable plant fiber paddy seedling cultivation disk and a preparation method thereof. The disposable tableware is prepared from the following raw materials in parts by weight: 90-100 parts of plant fiber, 60-70 parts of polyvinyl alcohol, 10-20 parts of modified starch, 10-15 parts of magnesium sulfate, 8-15 parts of modified calcium carbonate powder, 20-40 parts of waterproof glue, 6-10 parts of carboxymethylcellulose and 4-8 parts of white alum. The preparation method for the degradable plant fiber paddy seedling cultivation disk comprises the following steps of smashing, grinding, mixing, dissolving, moulding, coating with glue, drying and the like to obtain a finished product. The degradable plant fiber paddy seedling cultivation disk disclosed by the invention has the characteristics that the main raw material plant fiber is from crop straws and is a renewable resource with rich sources; preparation cost is low; the degradable plant fiber paddy seedlingcultivation disk can be reused as plant fertilizer by being dipped in soil after abandoning. The degradable plant fiber paddy seedling cultivation disk is favorable for the comprehensive utilizationof agricultural resources, is also favorable for alleviating an air pollution problem caused by crop straw combustion and can be used for effectively alleviating the problem of white pollution causedby using plastic products on a large scale.

Description

technical field [0001] The invention relates to the technical field of degradable seedling raising trays, in particular to a degradable plant fiber rice seedling raising tray and a preparation method thereof. Background technique [0002] With the acceleration of people's life rhythm, social life is developing towards convenience and sanitation. In order to meet this demand, disposable foam plastic lunch boxes, plastic bags, chopsticks, water cups, etc. began to frequently enter people's daily life. The appearance of these easy-to-use and cheap packaging materials has brought many conveniences to people's lives. But on the other hand, these packaging materials are often discarded after use, causing "white pollution", causing environmental hazards, and becoming a huge environmental problem. White pollution refers to plastic products such as packaging bags made of polystyrene, polypropylene, polyvinyl chloride, etc. Throwing and throwing away is difficult to degrade, causin...

Problems solved by technology

[0007] The current rice seedling trays in my country mainly use plastic seedling trays, which have problems such as high production costs, large storage space, and easy stacking of seedlings for machine transplanting.

In response to these problems, my country has carried out research on related biomass seedling trays since the 21st century, and developed a rice planting bowl seedling tray, which is a kind of rice husk powder as the main raw material and then added nutrients, chemicals and adhesives. The mixed seedling-raising soil substitute-phytosynthetic seedbed soil; at the same time, it has also developed a pot seedling tray made of fiber material from crushed rice straw and processed by specific molding, but this kind of seedling tray has The cultivated seedlings need to be equipped with corresponding pot cultivation transplanting machines to be transplanted, and the seedling trays have a large expansion rate when encountering water. Promotion and application area is small
