Abstract

This paper is a system for producing large quantities of grasses for forages, which are herbicides for herbivore animals such as cattle, cows, and cows throughout the year, all year round. As

As illustrated in FIG. 1, the thermal problem is solved at low cost by connecting the hot water heated by the solar heat collecting plate [7] in a small glass greenhouse to the superconducting heat pipe [4] heating system and automatically adjusting it. And multi-stage three-dimensional shelves [6] to maximize the area efficiency

By planting seed seeds in specially designed nutrient cultivation box [l0] and carrying out regular nutrient solution water cultivation, harvesting fresh grass of 20cm long every 7-8 days, this grass cultivation system produces about 30 pyeong of grassland By producing more than 180,000kg of annual output of about 10,000 pyeong, it will completely solve the problem of the research fee dependent on imports of millions of dollars per year, and also promote the growth of livestock, increase the production of oil, and save about 30% of the rich feed cost. It was.

Description

All-weather pasture-cultivated greenhouse system using solar heat

This paper is a cultivation system that produces large quantities of forage grasses, which are used in large-scale livestock farms such as poultry and pig farming, including Korean cattle, 24/7 using solar energy.

Korea, which lacks grassland area, relies on imports of feed grass for millions of dollars every year from foreign countries, but its supply is not smooth and it is supplemented with rice straw of pesticide pollution. Compared to New Zealand and the United States, only 60-70% of the population is placing a heavy burden on farmers.

Up to now, various kinds of greenhouses (glass, vinyl, PET, PC coating, etc.) of facility agriculture are heated with oil cutlet as raw material to grow fruits, vegetables, leafs, flowers, etc. In the case of livestock pasture, such high-cost plant cultivation is in a difficult stage even because it is not economical.

In order to solve this high-energy problem, this proposal forms a glass or transparent greenhouse (Fig. 1), primarily using direct sunlight from the sun, and secondly, installing a solar heat collecting plate (7). The hot water heated to about 80 ℃ is stored in the solar heat storage hot water tank (2), and then forcedly circulated by the circulation pump so that the heat conductivity is 1,000 times higher than that of the copper pipe. It solves the heating problem at low cost without using it at all, and prepares for emergency in case heat-absorbing tube is built in the heat storage tank in case of lack of solar heat storage in case of weather impurity.

In the present invention, in order to maximize the efficiency of the facility cost, the internal cultivation area can be utilized more than five times as much as the general greenhouse by installing the multi-stage shelves 6 with four or more stages.

In this specially designed nutrient cultivation box (10), sow grasses such as Orchardgrass, Laimac, and macaque seeds are sown in a separate seeding plate (11), and the nutrient solution for a certain time is sprinkled in the nutrient solution tank (3) containing fast growing culture solution. Automatic feeding through the nozzle (8) to grow more than 30 days in the general open field to grow grass of about 20cm long in 7 to 8 days to harvest every day

The area of about 3O people (100㎡) of the grass growing greenhouse system of the present invention produces more than 180.000kg of clean grass produced annually by 10,000 pyeong (33,000㎡) of general land, saving more than 30% of the total feed cost of farms I think it will contribute to the improvement of the farm budget.

In the present invention, the internal temperature control problem due to the hot water accumulated in the solar thermal storage hot water tank (2) and the water supply problem of the nutrient solution by the regular time period in the nutrient solution tank (3) are automatically controlled by the computer controller (9).

In particular, in order to reduce the required cost of forage seeds, a separate seeding plate (11) was installed in the nutrient solution cultivation box (10) to secure free development space of the roots, and when harvesting mature grasses, only the separated seeding plate (11) was separated. As a lawnmower, the roots were mowed, leaving the seedlings intact, so that seeding was done once and harvested three times in a row to drastically reduce seed costs.

For easy installation of this system, the basic steel structure is formed of a fully assembled steel frame (Fig. 3), and the multi-stage recultivation shelf (6) is also installed in such a pre-fab system to facilitate the dismantling movement reuse.

Nutrient cultivation water supply system is a circulatory system that recovers and reuses the nutrient solution once used, thus saving water and purifying the environment.

The present invention can completely solve the problems of feedstocks raised by farmers without relying on imports.In addition, the smooth supply of high-quality, clean and clean feedstuffs promotes the growth and production of livestock, as well as the total feed cost, which depends on the total imports. It is expected to save about 30% of billions of dollars annually).
