Description

Degradable nutrient flowerpot, nursery pot

The present invention relates to a flower pot and a seedling pot, and more particularly, to a flower pot and a seedling pot based on the fiber of a plant as a raw material which is degradable and has nutritional components.

Background technique

It is well known that flowers are delicate plants. In order to improve their survival rate, when raising seedlings, arranging flowers, transplanting and selling them, they are required to have soil in their roots. When raising seedlings and arranging flowers, usually the flower seeds or flower branches are directly placed in the soil. After the flowers grow and grow, the roots are dug out with soil and transplanted and sold. However, digging with a knife is not only troublesome, but also easily damages the flower roots; in addition, the root system of flowers is not developed, and the amount of soil that can be attached is small, and the soil during the re-moving process is easy to detach from the root.

In order to solve the problem of soil detachment from the roots, there are usually three methods: First, wrap the root of the flower with a straw rope. However, this method cannot completely prevent the soil from detaching from the roots, and it is unsightly when sold. Second, plant flowers in ceramic pots or clay pots. This method can effectively prevent the soil from detaching from the roots. However, ceramics or mud pots are bulky, fragile, and inconvenient to carry; and flower buyers often have preferences for flower pots and do not like ceramic flower pots or mud pots for growing flowers. Third, grow flowers in plastic pots or plastic films. However, the inner wall of the plastic flowerpot or plastic film is shiny, airtight, and has poor drainage performance. It is difficult for the flower roots to adhere to the inner wall; it is also not conducive to exchanging air with the outside world. This reduces the survival rate of flowers. In addition, plastic flower pots or plastic films cannot be recycled when they are discarded. They are "white garbage" and will pollute the environment. Chinese patent application number

The flowerpot of the present invention is prepared as follows:

Method 1: Shred the plant fiber, add the adhesive, auxiliary agent and organic fertilizer according to the above ratio, and add an appropriate amount of water, stir well, and place the raw materials in a mold with a 30-50 mesh metal net. Or directly placed in a mold with an exhaust device, in the range of 110 ° C ~ 200 ° C, hot-pressed and solidified, demoulded, cut the sides of the flower pots and seedling pots, and punch holes in the bottom or side walls. Obtain the flower pots and nursery pots.

Method 2: After plant fiber (straw pulp, wheat straw pulp, corn stalk pulp, sorghum stalk pulp, reed pulp, bamboo pulp, bagasse pulp, weed pulp, etc.) or pulp board is beaten with a pulper, add it in proportion Adhesives, auxiliaries and organic fertilizers. After the fibers are fully adsorbed, the raw materials are quantitatively placed in a mold lined with a layer of 30 ~ 50 mesh metal mesh, suction-filtered to absorb water, and then squeezed or directly at 110 ° C ~ It can be hot-pressed within 200 ° C, demoulding, trimming, punching at the bottom or side walls to obtain the flower pots and seedling pots.

The flower pots and seedling pots of the present invention have good air permeability. The following methods are used to conduct a breathability test on the flower pots and seedling pots. The method is as follows: using the specific pressure method: quantifying 100 ml of air and changing the thickness to 0.5 mm 20 pieces of pot material were measured; the results are as follows: The average time for each 100ml of air to pass through each piece of material is about 20 seconds.

The flowerpots and seedling pots of the present invention have good water-repellent properties. The water-repellent performance test is performed on the flowerpots and seedling-pots by the following method. The method is as follows: 0.1 ml of tap water drops are placed on the material of the flowerpot. The results are as follows: The minimum change in the height of the water drops is not greater than 30%; after the water drops roll, there is no trace in the original place.

When arranging flowers and raising seedlings, the flower seeds and flower branches can be placed in seedling pots, and when they grow up, they can be directly transplanted and sold with flower pots. The appearance, shape, size, and weight of the flower pot can be adjusted arbitrarily according to user requirements. At the same time, the special formula is added in the production process, so the flower pot has good air permeability, strong water repellency, and has certain moisture retention and fertilizer retention. At the same time, the side wall and bottom of the flower pot are perforated, and the flower pot has good drainage performance. The nutritional components can be formulated according to the requirements of flowers and plants. In addition, because the flower seeds or flower arrangements are placed in the seedling pots instead of directly on the ground, so It is not only easy to transplant and sell, but it will not damage the flower roots. Because plant pots use plant fibers (straw, straw, corn stalks, sorghum stalks, reed pulp, bamboo pulp, bagasse, weeds, etc.),

Replacement page (Article 26) It is made of environmentally friendly substances such as pulp and finally decomposes into an ideal organic fertilizer required by flower plants, so the flower pots are free of any pollution and are truly environmentally friendly products.
