Description

TECHNICAL FIELD The present invention relates to a nutrient composition for growing a fig tree,

The present invention relates to a nutrient solution composition for growing a fig tree and a method of using the nutrient composition. More specifically, the present invention relates to a nutrient composition for growing a fig tree, which comprises nutrients necessary for the growth of a fig tree, The present invention relates to a nutrient solution composition for cultivating a tree container, and a method for efficiently and efficiently cultivating a nutrient solution using the same.

The fig tree (Ficus carica L.) is a subtropical, subcultivated deciduous fruiting body, belonging to the genus Ficus L. ( Ficus L.) and having high commercial value. More than 600 varieties are distributed.

Fig trees are less susceptible to severe drying and submergence because of their low precipitation and warm environment, but their roots are shallow. Especially, we like the most alkaline soil in the fruit water and grow well in the soil of the pH 7.0 ~ 7.5 of the soil, and basically use lime (Ca) every year to increase calcium absorption.

Various technical measures are being taken to improve early shipment, quantity and quality, stabilize production, and distribute the efforts of harvester due to low productivity and low productivity due to low storability and rainfall at harvest. In order to solve these problems, It is growing.

The effect of facility cultivation has advantages such as favorable price by early shipment, improvement of quality and quality, stabilization of growth from meteorological disasters, expansion of effort distribution, expansion of management scale and reduction of disease. However, There are many disadvantages that integration failure occurs. Recently, the area of nutrient solution cultivation in containers such as boxes has been gradually increasing.

Nutrient solution cultivation is one of the cutting-edge agricultural technologies that plays a pivotal role in the development of the horticultural industry. In principle, it refers to cultivating crops with nutrients that are essential for crop growth without using soil. This includes hydroponics such as pond hydroponics, hydroponics, and capillary hydroponics. Apart from supplying the nutrients necessary for the growth of the crops, it also artificially cultivates the environment in which the crops grow using solid media made of peatmoss, pearlite, vermiculite, rock, pumice, sawdust, gravel and sand.

In Europe, nutrient solution cultivation became the main technology of the mass production system of fruit and vegetables mainly in the Netherlands and Belgium, and the cultivation of leafy vegetables developed into a plant factory with the settlement of pure hydroponic system.

The productivity of Korean fruits and vegetables has been remarkably improved in the 1990s, but the facilities are still underdeveloped. Due to the small size and the delayed introduction of modern technology, the productivity of the fruits and vegetables of Europe is about 1 / 10th to 1/10 of the productivity.

Hydroponic cultivation of grape varieties in the fruit juice was attempted in the form of box cultivation, but there was no further development due to insufficient cultivation techniques.

From this point of view, the nutrient solution cultivation technique of the fig tree could contribute to the improvement of the international competitiveness of the fig as a crop production technology which is essential for improvement of productivity, quality and stability.

In the past, the nutrient solution of fruits and vegetables in the vegetable was the Netherlands PBG nutrient solution [tomato: 14 (N) - 4.5 (P) - 9.25 (K) - 9.25 (Ca) (Mg) - 8 (K) - 8.5 (Ca) - 2.75 (Mg), and Meron: 9 (N) - 4 (P) - 8 (K) - 8 (Ca) - 4 (Mg) and red pepper: 17.3 (N) 4 (P) - 8 (K) - 8 (Ca) - 4 (Mg), cucumber: 17.3 (C) -1 (P) - 3 (K) - 2 (Ca) - 4 (Mg) (Mg)], and Shizuoka University Aquatic Solution [Meron: 14.3 (N) - 4 (P) - 6 (K) - 7 (Ca) - 3 (Mg)].

In Korea, Korea's raw liquid [tomato: 9 (N)-2 (P)-5 (K)-4 (Ca)-2 (Mg), pepper: 12 (N)-3 (P)-7 (K)- 4 (Ca)-2 (Mg), Cucumber: 12 (N)-2 (P)-7 (K)-5 (Ca)-2 (Mg), Leafy vegetables: 15 (N)-3 (P)-6 (K)-8 (Ca)-4 (Mg)] and Seoul municipal liquor [leaf vegetable: 10.8 (N)-2 (P)-6 (K)-3 (Ca)-2 (Mg)]] Rural Development Administration nutrient solution composition for green pepper culture medium [patent registration number: 1001734370000, nitrogen 8-22% by weight, phosphoric acid 5-12% by weight, kali 20-45% by weight, magnesium 3-10% by weight, calcium 10-25% by weight , Trace elements 1 to 2% by weight and water-soluble pigment 0.5 to 1% by weight], tomato culture medium composition [Patent No. 1002610240000, standard solution A is nitrogen (TN) 8.5% by weight, water-soluble girly (K ₂ O) 26.0 wt%, 5.0 wt% water soluble phosphoric acid (P ₂ O ₅ ), 0.15 wt% water soluble boron (B ₂ O ₃ ), 4.0 wt% water soluble goat (MgO), 0.2 wt% water soluble iron (Fe), water soluble manganese (MnO) ) 0.05% by weight, water soluble zinc (Zn) 0.005% by weight, water soluble copper (Cu) 0.001% by weight, water soluble Molybdenum (Mo) is composed of 0.0005% by weight, water-soluble pigment 0.05 ~ 1.0% by weight, standard B agent consists of 11.0% by weight of nitrogen (TN), 22% by weight of water-soluble calcium (CaO)], culture medium composition of cucumber [patent Registration: 1002610230000, Standard A agent is 9.5% by weight of nitrogen (TN), 29.5% by weight of water soluble garlic (K ₂ O), 4.0% by weight of water-soluble phosphoric acid (P ₂ O ₅ ), 0.12% by weight of water-soluble boron (B ₂ O ₃ ) %, 3.5% by weight of water-soluble goblet (MgO), 0.2% by weight of water-soluble iron (Fe), 0.05% by weight of water-soluble manganese (MnO), 0.004% by weight of water-soluble zinc (Zn), 0.001% by weight of water-soluble copper (Cu), water-soluble molybdenum ( Mo) 0.05% by weight, water-soluble pigment 0.05-1.0% by weight, standard B agent consisting of 11.0% by weight of nitrogen (TN), 22.0% by weight of water-soluble calcium (CaO)] has been developed.

The conventional nutrient solution compositions as described above are compositions for fruit vegetables and leafy vegetables and are composed of only fertilizer salts and are not suitable for use as a nutrient solution for cultivating a fig tree because they are constituted without using specific compositions for each growing stage .

Accordingly, the present inventor has made efforts to develop a method for growing a fig tree in a nutrient solution and a nutrient solution effective for the cultivation of a fig tree.

As a result, it was possible to develop a nutrient solution composition capable of smoothly providing various essential components in the cultivation of the fig tree nutrient solution, and it was confirmed that when the fig tree is cultivated using this nutrient solution composition, it is possible to effectively obtain a high quality fig Thereby completing the present invention.

Accordingly, it is a main object of the present invention to provide a nutrient solution composition which can be used for cultivation of a nutrient solution of Fig.

It is another object of the present invention to provide a method for growing a fig tree in a nutrient solution using the nutrient solution composition.

According to one embodiment of the present invention, the present invention is 28 to 40% by weight of potassium nitrate (KNO ₃ ), 3 to 7% by weight of ammonium monophosphate (NH ₄ H ₂ PO ₄ ), calcium nitrate (CaNO ₃ · 4H ₂ O ) 27 to 37% by weight, calcium chloride (CaCl ₂ · 2H ₂ O) 7 to 14% by weight, magnesium sulfate (MgSO ₄ · 7H ₂ O) 13 to 20% by weight, chelate iron (Fe-EDTA) 0.5 to 3% by weight , Boric acid (H ₂ BO ₃ ) 0.05 to 0.5% by weight, manganese sulfate (MnSO ₄ · 4H ₂ O) 0.05 to 0.5% by weight, zinc sulfate (ZnSO ₄ · 7H ₂ O) 0.005 to 0.05% by weight, copper sulfate (CuSO ₄ 5H ₂ O) 0.0005 to 0.01% by weight and sodium molybdate (Na ₂ MoO ₄ 2H ₂ O) one or two or more microorganisms selected from the genus Bacillus or Penibacillus genus microorganisms Provides a nutrient solution composition for growing a ficus tree container, characterized in that it further comprises 10 to 10 ⁵ CFU / g per one microorganism based on the weight of the base composition. .

At this time, the nutrient solution composition means a dried state, and is a composition for preparing a nutrient solution by adding a certain amount of water before use.

In the nutrient solution for fig tree cultivation of the present invention, the content of each of the above components is determined in consideration of the solubility and the ratio of the necessary inorganic nutrients required for the cultivation of the fig tree, will be. The fig tree grows well in neutral and weakly alkaline soil compared to other fruit trees, and it is a suitable composition because it is a fruit tree with a large amount of Ca (Ca) requirement.

16 kinds of elements (carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, molybdenum and chlorine) are required for the growth of fig trees. Among these, six elements such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S) are relatively large- It is an element. Since carbon, hydrogen, and oxygen among the 16 elements are supplied as carbon dioxide gas (CO ₂ ) and water (H ₂ O) in the air, it is not necessary to supply them as fertilizer. Chlorine (Cl) Since it is often contained in a certain amount, it is not necessary to supply it as fertilizer except for special cases.

The amount of these large and trace elements varies depending on the crop.

The culture conditions used in the nutrient solution culture must include the first essential inorganic nutrients, the second is the ionic state dissolved in water in a form that is easy to absorb in the roots, and the third one is dissolved at a proper concentration, The pH of the solution should be in the range of 5.5 to 6.5, the fifth must be made of the cheap fertilizer, and the concentration of the inorganic element should be maintained even after the sixth cultivation period. The ratio and pH change should be small.

The nutrient solution composition of the present invention is configured to satisfy all of the above conditions, and is a nutrient solution composition capable of maximizing the cultivation efficiency of Fig.

Since nutrients required for growth vary depending on the season in the cultivation of fig trees, it is preferable to form the nutrient solution composition by dividing into early stage, middle stage, and late stage in order to optimize nutrient supply in each stage.

The initial stage of fig tree growth is from the germination stage to the beginning and the beginning stage (30 days), and the middle stage is the harvest stage from the beginning stage to the harvest stage.

In the middle stage, the nutrient solution composition may be used as it is.

Preferably, the nutrient solution composition for initial use to optimize the nutritional supply further comprises 4 to 9% by weight of the draft (NH ₄ NO ₃ ) based on the base composition.

Nutrient compositions for use in the latter to optimize the feeding further includes a draft (NH ₄ NO ₃₎ and 4-sulfate of potassium to 9% by weight (K ₂ SO ₄₎ of 4 to 9% by weight, based on the base composition .

In the nutrient solution composition of the present invention, the microorganisms convert the nutrients in a form that can not be absorbed by plants into an absorbable form, and induce plant growth and antagonistic effects, thereby reducing salt accumulation obstacles in the medium And maximize the efficiency of cultivation of fig trees and the productivity of figs.

For this purpose, it is preferable to include one or more microorganisms selected from microorganisms belonging to the genus Bacillus or Penicillium, and the microorganism concentration is preferably 10 to 10 ⁵ CFU / g per microorganism.

Examples of the microorganisms include Bacillus subtilis subtilis), Bacillus MEGATHERIUM (Bacillus megaterium), Bacillus Fu milreoseu (Bacillus pumilus , and Paenibacillus polymixa . These strains can be used alone or in combination. Most preferably, all of the above four strains are included.

In order to apply the nutrient solution composition of the present invention to the cultivation of fig tree, it is preferable to mix it with water and sufficiently dissolve each component of the composition to prepare a nutrient solution, wherein 0.1 to 5 parts by weight of the nutrient solution composition is mixed with 1000 parts by weight of water A method of mixing can be used. The ratio of the nutrient solution to water is an appropriate range in which each component of the nutrient solution can be sufficiently dissolved in water. When the proportion of the nutrient solution composition is increased, the components of the nutrient solution composition do not sufficiently dissolve to remain in a form that can not be absorbed by the fig tree and may be combined with other elements to cause precipitation, which is inefficient. If the ratio of the nutrient solution composition is lowered, It is undesirable because it is diluted more than the target concentration.

The nutrient solution composition of the present invention contains all the nutrients necessary for the growth of the fig tree and can be produced by the nutrient solution and can be easily supplied to the fig tree at any time when necessary. Excellent effect can be expected in container cultivation where supply is not easy.

It is possible to cultivate the fig tree by cultivating the nutrient solution cultivation medium in a container of a certain volume and planting the fig tree and then periodically feeding the nutrient solution prepared by adding water to the nutrient solution composition of the present invention.

The nutrient solution culture medium serves to fix the fig tree roots in place of the soil, plays an intermediate role in supplying nutrients, water and oxygen, and can be prepared by mixing pearlite and peat moss at a weight ratio of 1: 1.

Since the nutrient composition for growing fig tree can be adjusted in accordance with the pH and EC of the raw water by diluting a certain amount of water with the water in each initial stage, middle stage, and late stage, the pH and EC measuring device are not necessary. It can be easily produced and used in a nutrient solution, and it is very convenient. Also, since the nutrients necessary for the growth of the fig tree are appropriately contained, when the cultivation of the fig tree is carried out using the nutrient solution, it is possible to increase the yield and produce the high quality fig have. Especially in a nutrient solution cultivation using a container.
