Description

Foaming type culture medium for hydroponics {Foaming Type Media for Hydroponics Cultivation}

The present invention relates to a blowing agent-type culture medium for hydroponic cultivation, and to a hydroponic cultivation foam-type culture medium that can be used quickly and conveniently in a domestic hydroponic cultivation system.

Hydroponic cultivation refers to a method of growing plants in a culture made of water and water-soluble nutrients without using soil, and is called water cultivation or watering. The hydroponic cultivation can directly observe the condition and growth of the roots, produce clean vegetables or crops that are not contaminated, and can be easily grown in the house, thereby decorating the house. Plants that can be hydroponic are mostly monocotyledonous plants. In addition, bulbs such as tulips, hyacinths, daffodils, fruit trees such as pineapples, taro, sweet potatoes, onions, sprouts and other vegetables such as begonia, violet, geranium, and marigold, plants such as pepperoni, ivy, and lucky trees are all hydroponic. Is possible.

When growing plants in soil, it is impossible to know what nutrients are needed for plant growth and how they affect plants. This is because the soil already contains various nutrients, so it is not possible to know the effect of artificially supplied nutrients (fertilizer components). Therefore, by comparing the plants grown by hydroponic cultivation with a culture medium made by subtracting a specific nutrient from a plant growing in a culture medium containing all the nutrients necessary for plant growth, the nutrients required for plant growth and their functions can be identified.

Hydroponic cultivation is possible to prevent continuous obstacles, and it can be cultivated continuously over a long period of time in the same place, stable harvesting is possible without any difference in wind, and the environment under the ground can be adjusted to optimum conditions regardless of land conditions. Cleanliness can reduce malignant work. In addition, it is possible to mass-produce fresh and clean high-quality vegetables year-round, and has the advantage of automating or factory-producing all production. However, as a disadvantage, it requires technology such as culture composition composition and concentration correction and pest prevention measures, and water, not soil, has low buffering capacity and is sensitive to environmental changes. Therefore, the development of a culture solution capable of compensating for this is urgently required.

In the meantime, cultures have been developed for various crops such as Japanese vegetable test center culture and Yamazaki culture, and most of them are mainly for culture of fruit and vegetable cultivation among vegetables, most of which are suitable for adversity cultivation or cultivation of bile (Sonneveld, 1993; Adams). , 1992; 倉 石, 1982).

4-2: Secondary test with or without amino acids

Growth was verified for 60 days using a culture medium with or without amino acid addition to 4 hairs of Vitavia (lettuce), 4 hairs of vitamin (colorful), and 3 hairs of basil (herb) (FIGS. 10 and 11).

As a result, the EC concentrations increased with time for both cultures for 60 days, and the pH concentrations also showed an average of 6.0 to 8.0 (FIG. 11). In addition, both cultures were grown without abnormality in the harvest. However, there was little floating, sedimentation and turbidity in the culture solution to which no amino acids were added.

However, in terms of gloss and texture, it was found that the plants of the culture medium in which amino acids were added to the maximum were better (Table 11).

(# 1: Amino acid added oil, # 2: No amino acid added)

Example 5: Confirmation of initial growth potential with only trace elements

In order to confirm the possibility of initial growth with only trace elements among essential nutrients of the culture broth, growth was carried out using 1 B agent, 50% integrative agent C agent and 1 set of A and B agents used in Examples 1 to 4 It was investigated for one day.

Table 12 below shows the composition of the expanded culture medium, and Table 13 shows the culture medium used in this example by type.

As a result, the growth state of the 50% integrating agent using one agent C and the one using agent A and B was similar, but the plant using only agent B composed of only trace elements did not grow well (FIG. 12).

In addition, it was found that the root mass period was short when one of the C agents was used (FIG. 13). When the root body is severe due to root damage, the water absorption is not smooth and the evaporation is not performed well. That is, it can be judged that it will be more advantageous for growth when hydroponic cultivation is performed using one of the 50% integrating agents shown in Table 2 or a set of A and B agents.
