Problems solved by technology

In the existing greening construction, especially in the construction process of herbs and shrubs for greening, the seedlings are transported and planted in units of nutrient cups, and when planting, the nutrient cups under the seedlings are first removed, The damage to the root system of the seedlings is easy to be caused during this process, which will affect the survival rate of the seedlings after planting; and the plastic is difficult to degrade, increasing the environmental pressure
[0003] If a nutrient cup that can be effectively decomposed by the soil can be produced, it will be able to effectively solve the above-mentioned problems that the roots and shoots are destroyed and the environment is difficult to degrade. At present, the production of degradable nutrient cups mainly uses starch and cellulose, but due to starch, fiber Some inorganic cross-linking agents are commonly used to treat starch and cellulose due to the poor cross-linking properties of starch. However, the use of inorganic cross-linking agents will lead to the residue of harmful substances during degradation. At present, my country is a big banana-producing country, and bananas will be produced after harvesting. The stems, which are nearly equal to the fruit, are mostly discarded in various production areas in my country, which not only causes environmental pollution in the banana garden, but also wastes a lot of plant resources

Embodiment 1

[0038] A preparation method for preparing a nutritional cup using banana fiber, the method is:

[0039] (1) prepare banana fiber:

[0040] (1) Raw material pretreatment: take the banana peel, leaves or stems and cut them into sections, and then tear the pieces into flakes with a thickness of 0.5 mm, press, scrape, and dry to obtain hemp;

[0041] (2) Degumming treatment: the hemp in step (1) is sequentially subjected to expansion treatment, oxidation treatment, acid treatment, biological enzyme treatment, enzyme inactivation treatment, dehydration, oil supply, and drying to obtain crude fiber;

[0042] The processing method of the puffing treatment is: mix the hemp with the sodium hydroxide solution whose mass concentration is 2g / L and mix according to the solid-to-liquid mass ratio of 1:17, then rapidly heat to 95°C, and boil at constant temperature for 20min, Drain the sodium hydroxide solution, remove the hemp, put it in hot water with a pressure of 7MPa and a temperature ...

Abstract

The invention relates to the technical field of processing of seedling raising pots, and in particular relates to a banana fiber seedling-raising pot and a preparation method thereof. The seedling-raising pot is prepared from banana fibers, acetic anhydride, concentrated sulfuric acid, starch, glycerin, polyhydroxybutyrate, chitin, fibroin and an ethanol solution. The method provided by the invention uses the banana fibers to react with the acetic anhydride and the concentrated sulfuric acid to prepare acetate fibers, uses the starch, the glycerin and the polyhydroxybutyrate to prepare a starch gel, uses the chitin, the fibroin and the ethanol solution to prepare a shell mucilage, then the acetate fibers, and the starch gel and the shell mucilage are mixed to prepare the seedling-raising pot; and the method can effectively improve the forming capacity and impact resistance of the seedling-raising pot, and the seedling-raising pot can be biodegraded by microorganisms in soil.

Description

【Technical field】 [0001] The invention relates to the technical field of nutrition cup processing, in particular to a banana fiber nutrition cup and a preparation method thereof. 【Background technique】 [0002] Nutrition cups, also known as seedling pots, are generally made of black plastic. The cup-sized ones are used for breeding and seedlings, while the flowerpot-sized ones are mostly used for greenhouse planting. The black plastic nutrition cup has the functions of heat absorption during the day, heat preservation and root protection at night, and fertilizer preservation, and has the function of water retention in the dry season; breeding and seedlings with the nutrition cup are convenient for centralized cultivation and transplanting, and significantly improve economic benefits. They are widely used in flowers, vegetables, melons, etc. Fruit and other agricultural planting. In the existing greening construction, especially in the construction process of herbs and shrub...
