Description

Vulcanized and Leafy Vegetables Filled with Wood Medium and Solid Medium for Nutrient Solution

The present invention relates to a planting container for planted vegetation and leafy vegetables using wood waste, and to a wood medium to be filled therein, and a solid medium for cultivation of nutrient solution. The present invention relates to a cultivation container of a shape, a wood medium added with essential nutrients to be filled thereto, and a solid medium for nutrient cultivation that can replace conventional rock wool medium. The herbaceous and leafy vegetable cultivation container is a container mainly used for planting and planting various herbaceous and leafy vegetables such as tubular vinegar. It is. In the present invention, the vegetable growing and vegetation wood growing container means a container containing a wood medium therein. In addition, the solid medium defined in the present invention is defined as a medium to replace the function of the rockwool medium for agriculture used in nutrient solution, especially rock wool cultivation.

In general, pollen, which is a container for planting vegetation and leafy vegetables, is widely used as a synthetic resin, or made by baking with clay, but these conventional flower pots do not have a thermal and moisturizing effect. Easily changed depending on the temperature, it was difficult to sufficiently maintain the various conditions necessary for the growth environment of the plant, and in particular, the pollen, whose material is synthetic resin, was difficult to dispose of the waste. In addition, the pollen, whose material is clay, has been pointed out as a weak durability because it is not excellent in strength, such as easily damaged by external impact.

However, most of all, the conventional culture cultivation soil filled in the conventional cultivation vessel contained a number of problems to manage indoors. For example, when cultured soil treated with immature compost is used, contamination of various microorganisms as well as odor has become a big problem in indoor hygiene.

The present inventors pay attention to the fact that the wood-based by-products have moisturizing and warming characteristics, and that the wood-based by-products have a large porosity if they form a certain volume, so that oxygen supply is smooth. It was invented that wood media, which are growth media to replace conventional culture soils, can be prepared. In addition, if the application of the wood properties in the production of cultivation container, not only can be prepared for the cultivation container suitable for the plant growth environment, but also recognized that it will be a great help in the utilization of wood waste to complete the present invention.

In addition, the wood properties were evaluated to be able to replace the rock wool used in nutrient cultivation.

Generally, rock wool cultivation refers to cultivation by supplying a culture medium using rockwool, which is an artificial medium, without using soil quality. However, the rock wool has a porosity of about 95%, so if water is supplied excessively, there is a problem such as poor drainage and crop roots. In particular, rock wool not only depends on imports, but rock wool does not rot in the soil. There were many problems with waste disposal.

The present inventors propose to use wood by-products such as sawdust as a solid medium to replace rock wool. It is to prepare a solid medium for nutrient cultivation having a porosity of about 60% to 90% by using a natural adhesive such as wood-based by-products and starch adhesive.

An object of the present invention is to provide a container for growing vegetation and leafy vegetables using wood-based by-products.

Another object of the present invention is to provide a wood medium to replace the conventional culture soil by using wood-based by-products, and another object is to propose a solid medium for nutrient cultivation replacing the conventional rock wool using wood-based by-products.

Another object of the present invention is to utilize wood waste usefully.

Hereinafter, the present invention will be described in detail through various embodiments.

(Example 1)

Wood Cultivation Container Manufacturing

Sawdust and urea resin with a particle size of 10 to 100 mesh dried by 90% or more are mixed in a weight ratio of 80 to 20, and then molded into a conventional flowerpot shape using a conventional molding press and hot pressed (pressure: 40kgf / ㎠, temperature : 150 ° C., processing time: 10 minutes) A wood cultivation vessel was prepared.

As a wood raw material, not only sawdust but also large rice or bark may be used, and it is preferable to have a particle size of 10 to 100 mesh.

The adhesive mixing ratio is preferably not more than 40% of the total weight of the growing container. Mixing of adhesive resins further may cause environmental pollution.

(Example 2)

After the wood particles and the phenol resin having a particle size of 10 to 200 mesh dried at least 90% were mixed in a weight ratio of 70 to 15, a wood cultivation container was manufactured under the thermal pressure condition of Example 1.

As the adhesive resin, synthetic resin adhesives such as urea resin or phenol resin were used, but the present invention is not limited thereto, and natural adhesives such as starch may be mixed with synthetic resin adhesives.

Example 1 and Example 2 relates to a wood cultivation vessel, the cultivation vessel produced by this can absorb external impacts due to the nature of the wood to increase the impact strength, resulting in a warm and moisturizing effect, so that the soil or filled inside The wood medium to be described in the following is to prevent the easy drying to maintain the proper humidity at all times will be able to give the best conditions appropriate for the growth of the plant.

The inventors noted that woody properties can also replace conventional cultured soils.

(Example 3)

Manufacture of Wood Medium Filled in Cultivation Container

Solid nitrogen, phosphate, and nutrients of urea were mixed in wood flour having a particle size of 10 to 100 mesh dried more than 90%, and aged at 40 ° C. to 50 ° C. for 24 to 48 hours. Thereafter, solid mineral nutrients were added at room temperature, and wood mat was prepared by re-aging at 40 ° C. to 50 ° C. for at least one day. The mineral nutrients include sulfur, magnesium, calcium powder and manganese, iron and boron powder. Some water may be added during the aging process to improve the adsorption of nutrients by wood flour, but this is not necessary.

As described above, when the wood medium is made of wood powder of 10 to 100 mesh, and filled in a predetermined space so as not to be unreasonable (as in the case of filling conventional soil soil), the porosity can be maintained at about 30% and supply oxygen. It was found that the degree is preferable. The present inventors used sawdust as wood powder according to Example 3, but other wood raw materials may be used under the premise of having a particle size of 10 to 100 mesh. Plant nutrients may use commercially available fertilizers, and wood-based raw materials may be used by performing sterilization steps in advance.

The present inventors are intended to claim the woody medium and leafy vegetable wood cultivation container filled with the vegetation and leafy vegetable cultivation container prepared in Example 1 or 2 as a feature of the present invention.

In addition, the present inventors prepared a solid medium for nutrient cultivation to replace rockwool used for nutrient cultivation.

(Example 4)

Solid medium for nutrient solution

Sawdust with a particle size of 10 to 200 mesh and a liquid starch adhesive mixed at a weight ratio of 70 to 30 were mixed in a weight ratio of 70% to 30, and a medium for nutrient solution cultivation medium having a thickness of 7.5 mm and a width of 20 mm was formed. Cm 2, temperature: 35 ° C., elapsed time of hot pressing: 24 hours) to complete the solid medium. The sawdust is representative of wood flour, but not limited thereto, and various types of wood flour may be used. Starch adhesives represent, but are not limited to, natural adhesives. Preferably the adhesive ratio does not exceed 40% or more and should also be 10% or more. Wood grading should be in the range of at least 10 and at most 300.

The cutting porosity of the solid medium is maintained at about 50%, and may be adjusted according to the thermal pressure conditions or the sawdust granularity. The porosity of 50% is estimated to be a porosity that can solve various problems that may occur within 95% of rock wool porosity.

Nutrient cultivation medium of Example 4 can be utilized not only for formal cultivation but also for transplantation cultivation. Here, formal cultivation means that the plant grows in one place from the seeding state to the growth harvest, and transplantation cultivation means seeding the seed and transferring it from the grown state to the other place after germination. Usually, vegetables such as peppers and eggplant tomatoes are cultivated and root vegetables such as sweet potatoes and carrots are cultivated. In particular, the solid medium according to the present invention is made of a natural friendly wood and natural adhesive, so it is possible to transplant the solid medium itself instead of only germinating sprouts on the medium to contribute to productivity.

As described above, the present inventor has described in detail the vegetation and leaf vegetable cultivation vessel using wood waste and the wood medium to be filled therein, and also described the nutrient solution cultivation solid medium using wood waste.

The vegetable and cultivated wood powder cultivation container and solid medium for cultivation of nutrient solution are manufactured and manufactured using pure natural resources, which are effective in preventing environmental pollution, as well as providing optimal plant growth conditions by providing warmth moisturizing and proper porosity. will be. In addition, the solid medium for nutrient cultivation made of wood flour can be grown directly by moving the medium itself to the soil when transplanted cultivation can contribute to productivity improvement through labor reduction. Conventional nutrient solution rock wool is all imported from a foreign country so the nutrient solution culture medium according to the present invention may obtain an import substitution effect.
