Abstract

Ginger's national cultivation area is 6,429ha and seed purchase cost is 51%. To enhance the competitiveness of ginger cultivation, it is urgently required to reduce production cost by stable supply of fine seed ginger, but until now, due to corruption due to long-term storage The seeding plant length is 2 to 3 times higher than the harvesting period because the loss rate is about 20-30%.

In order to solve this problem, mass production of seed ginger was possible through the cultivation of cultivation using ginger tissue culture seedlings developed by the inventors (Honam Agricultural Test Center). However, nutrient solutions developed at home and abroad are mainly vegetable and fruit vegetables, and nutrient solutions for ginger using tubers have not been developed. Therefore, during the “Ginger seedling production and safety cultivation research”, the seedlings of ginger tissue culture seedlings based on plant analysis values Successfully invented a production-only nutrient solution.

Experiments to determine the effect of the present invention, the ginger tuber weight was 40.4g per week, 92% more than the cultivated field (7 months, 21g / week), the survival rate was 83% than the open field (13%) In '97, the multi-stage annual nutrient solution cultivation test in greenhouse grew more than 40g per week in three months of growing season.

The nutrient solution composition of the present invention is 833 g of potassium nitrate (KNO ₃ ), 353 g of calcium nitrate (Ca (NO ₃ ) ₂ ) 4H ₂ O, 60 g of ammonium monophosphate (NH ₄ H ₂ PO ₄ ), and sulfuric acid in one ton of water. 186 g of magnesium (MgSO ₄ · 7H ₂ O), 20 g of iron chelated iron (Fe EDTA), ₃ g of boric acid (H ₃ BO ₃ ), ₂ g of manganese sulfate (MnSO ₄ · 4H ₂ O), zinc sulfate (ZnSO ₄ · 7H ₂ O) 0.22 g, copper sulfate (CuSO ₄ .5H ₂ O), 0.05 g, and sodium molybdate (Na ₂ MoO ₄ .2H ₂ O) 0.02 g were mixed and formed.

Using the present invention can produce a large amount of seed ginger by cultivating the ginger tissue culture seedlings can be reliably supplied seed can be expected to reduce 42% cost of seed seed when growing ginger.

Description

Nutrient Composition for Seed Ginger Production of Ginger Tissue Cultured Seedlings

The present invention relates to a nutrient solution composition for seed production of ginger tissue culture seedlings. Still another object of the present invention is to provide a stable and inexpensive large amount of seed ginger by cultivating cultivation of ginger tissue seedlings to reduce the cost of ginger seed purchase to improve productivity and income. Ginger has been widely used in tastes, spices, teas, and herbal medicines in both East and West.

Conventionally, there is no nutrient solution composition for tissue culture developed at home and abroad for ginger cultivation, and nutrient solution composition for leafy and fruit vegetables was developed, but there was a problem that is not suitable for cultivation of ginger tissue culture seedlings. Using the ginger tissue culture seedlings developed by the inventors (Honam Agricultural Test Center), mass production of seed ginger was possible through cultivation of nutrient solution. However, nutrient solutions developed at home and abroad are mainly vegetable and fruit vegetables, and nutrient solutions for gingers using tubers have not been developed. Successfully invented a production-only nutrient solution.

In ginger farming in Korea, the cost of purchasing seed ginger is 51% of the production cost, and it is urgently required to reduce production cost by the stable supply of superior seed ginger, but until now, the loss rate is about 20-30% due to corruption due to long-term storage. As a result, the seeding time of ginger seeds is two to three times higher than that of the harvesting season, and the improvement of productivity is urgently required.

The present invention is a method for supplying superior seedlings, which is based on the plant analysis values normally grown in natural conditions to suit the tissue culture seedlings of tissue culture nutrient solution composition that has not been developed at home and abroad for ginger cultivation Five kinds of composition liquids were disclosed and cultivation tests were conducted for a long time to invent the nutrient solution composition of the present invention.

The nutrient solution composition of the present invention contains nitrogen, phosphoric acid, and kali as main components, and contains calcium, magnesium, iron, zinc, copper, etc., as a mineral, and boric acid, molybdenum, etc., as trace elements, and is a very nutrient solution composition for tissue culture of ginger.

Figure 1 shows the growth of seedlings by nutrient composition.

Figure 2 shows the nutrient cultivation greenhouse foreground of the ginger tissue culture seedlings.

The nutrient solution composition of the present invention is prepared by mixing potassium nitrate, calcium nitrate, monobasic ammonium phosphate, magnesium sulfate, iron chelate, boric acid, manganese sulfate, zinc sulfate, copper sulfate, and sodium molybdate in water. The tuber weight of ginger tissue culture seedlings was 40.4g / week, 92% more than the cultivation (7 months, 21g / week), and the survival rate was 83%, higher than that of noji (13%). In '97, the nutrient composition of the present invention was disclosed and the result of the test in the greenhouse showed that the growth of more than 40g per week in three months was excellent in the nutrient composition.

Example 1

833 g of potassium nitrate (KNO ₃ ), 353 g of calcium nitrate (Ca (NO ₃ ) ₂ ) 4H ₂ O, 60 g of ammonium monophosphate (NH ₄ H ₂ PO ₄ ), and magnesium sulfate (MgSO _{4 2} O) 186 g, iron chelated iron (Fe EDTA) 20 g, boric acid (H ₃ BO ₃ ) 3 g, manganese sulfate (MnSO ₄ 4H ₂ O) 2 g, zinc sulfate (ZnSO ₄ · 7H ₂ O) 0.22 g, copper sulfate (CuSO ₄ · 5H ₂ O) 0.05g, sodium molybdate (Na ₂ MoO ₄ · 2H ₂ O) 0.02g is mixed and the nutrient solution concentration is NPK-Ca-Mg = 11.5-1.5-8-3-15me / ℓ Composed composition.

As a result of the test conducted for the nutrient solution development of ginger seedlings in 1996, the growth and tuber weight between the nutrient solution and the open field cultivation were 92% higher than those of the cultivated field. In addition, the survival rate was 83%, which is higher than the open field (13%), which proved the superiority of the shoe nutrient solution.

In comparison with the cultivation of ginger by the nutrient composition of the present invention, the tuber weight and survival rate per week were also significantly higher, which contributed greatly to the yield increase. In addition, the nutrient solution composition of the present invention can increase the growth period of the seed ginger because of the rapid growth rate and can supply the seed ginger in large quantities at a lower cost than the conventional seed purchase cost.
