Straw water storing seedling growing bowl and its production method

Abstract

A seadling growing bowl is prepared from pulverized straw and / or stalk and adhesive (polyacrylamide) in weight ratio of 100:(0.2-1). Its advantages are low cost, and no pollution.

Description

technical field [0001] The invention relates to a seedling raising container and a manufacturing method thereof, in particular to a seedling raising container manufactured using natural plants as raw materials and a manufacturing method thereof. Background technique [0002] In modern agriculture, it has become a mature technology to use containers to raise seedlings and transplant field crops, vegetables, flower varieties and forest tree varieties in advance. At present, the most used seedling container is plastic nutrient pot, but because plastic products are usually relatively dense, plant roots cannot pass through the wall of the nutrient pot, so the nutrient pot must be removed before transplanting. Body loosening often causes damage to the root system of plant seedlings, reducing the survival rate of transplants. [0003] For the problems referred to above, people have invented multiple nursery containers, such as "peat fiber and wood pulp is the peat seedling contain...

AI Technical Summary

Problems solved by technology

The raw materials of the container are degradable swamp humus peat and pulp raw materials, so the seedling container and the seedling can be transplanted together without damaging the root system of the seedling, thereby greatly improving the survival rate of the seedling, but the raw material source of the container is limited. In the process, pulp needs to be added, the production process is complex, the cost is high, and it is difficult to popularize and apply on a large scale

[0004] Chinese patent 99113554 discloses "Plant Fiber Seedling Pot and Its Manufacturing Method", which uses plant fiber materials, adds starch as a binder, uses paraffin or rapeseed oil as a release agent, and molds it under heating conditions. A large amount of starch and rapeseed oil are used in the process, and the production cost and price are very expensive. If paraffin is used instead of rapeseed oil, the cost can be slightly reduced, but paraffin is not easy to decompose in the soil, and when the amount is large, it will destroy the soil structure. Not suitable for mass use

This method requires the mold heating temperature to reach 170-210°C, which requires high molding machinery, complicated process and high energy consumption, so the product cost is relatively high. In addition, the strength of plant fibers is greatly reduced after the above high temperature, and the seedling pot The strength is also low, and it is easy to be damaged during use and handling, especially it cannot be used for saplings or large plant seedlings or transplantation, so it has certain limitations in use
