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 the nutrient solution composition focusing on salts and fruits is developed, but there is 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 solution for ginger using tubers has 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 an improvement in 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 minerals, and bongsan, molybdenum, etc. as trace elements, and thus is a nutrient solution composition suitable for tissue culture of ginger.

Figure 1 shows the growth status of seed growth by nutrient composition.

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

The nutrient solution composition of the present invention is potassium nitrate, calcium nitrate, monoammonium phosphate, magnesium sulfate, iron chelate, bongsan, manganese sulfate. A nutrient solution composition is prepared by mixing zinc sulfate, copper sulfate, and sodium molybdate. The tuber weight of ginger tissue culture seedlings was 40.4g / week, 92% more than the cultivation (7 months, 21g / week), and 83% survival was higher than that of noji (13%). In 1997, the nutrient solution composition of the present invention was disclosed, and the result of the test in the greenhouse showed that the nutrient solution composition was excellent by growing more than 40g per week in 3 months.

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 · 7H) in 1 ton of water 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 M ₀ O ₄ · 2H ₂ O) 0.02g is mixed and nutrient solution concentration NPK-Ca-Mg = 11.5-1.5-8-3-1.5me composition consisting of / l.

Test results for nutrient solution development for seeding of ginger tissue seedlings in 1996. Growth and tuber weight between nutrient solution and field cultivation were 92% of tuber weight compared to field cultivation as shown in <Table 1>. Was further increased, and survival rate was 83%, which is higher than that of the open field (13%), which proved the superiority of shoe nutrient solution.

Example 2

On the basis of the same compound as in Example 1, the inorganic salts of the macroelements and the microelements were mixed to obtain a nutrient solution composition, and the cultivation test results are shown in Table 3, respectively.

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.
