Ⅱ. Results of discusion
This experiment was conducted to develop stable production system and processing technology for expanding to use Danji radish.
To select of optimum sowing date and planting density for stable production leaf and root of Danji radish in Jeju. Danji radish seed was sowed at 8 times from August to October in 2011. Root weight was increased by late sowing in August but root growth was decreased when seed was sowed in September to October. Sowing on August 25 showed the heaviest of root weight and the highest yield per 10a. The optimum sowing date for Danji root production was estimated the lately August. It was available to produce radish leaves from November to March when seed was sowed sequentially on September. It is difficult to root growth because of increase bolting when the seeds were sowed March and April.
Danji radish seed was sowed spacing of 60×10cm, 60×20cm, 60×30cm, 60×40cm, 60×50cm in order to investigate the effect of planting density on the growth and yield. Leaf weight and root weight has decreased with the increase of planting density. But 60×10cm treatment was the highest yield of radish leaves and 60×30cm treatment was the highest yield of Danji radish.
In order to compare with the production of radish leaf cultivated 4 varieties. Leaf weight was the heaviest in Danji radish, followed Baekja, Asia-shiraegi and the lowest in Kwandong. Danji radish was the highest yield per 10a of radish leaf in 4 varieties.
Chemical characteristics, enzyme activities and Vitamin C contents of danji radish and winter radish in jeju were analyzed. The water contents of danji radish and winter radish were 82~84% and 90~92%, respectively. Soluble solids , Crude protein and mineral contents of danji radish were higher than other samples. Enzyme activities of samples, α-amilase of danji radish was higher than other samples, whereas protease was lower. Vitamin C contents of danli radish and winter radish were 40~48mg/100g and 14~30mg/100g, respectively. A fresh danji radish is a good source of vitamin C.
In case of dried radish, calcium, iron in mineral contents of danji radish were materially increased than fresh radish. Total phenol and DPPH of danji radish were lower than other smaples, whereas like fresh radish, Dried radish made of danji radish also was higher than other samples about Vitamin C contents. Production yield per 10a of danji radish was 12,025kg, these were able to produce 973kg dried radish. These production had gone up of 8% compared to winter radish.
Crude protein of danji radish and winter radish, which radish leaves harvested intervals of about 30days from Dec.15 were 2.8~4.3% and 2.4~3%, respectively. In case of radish leaves as much as radish, Vitamin C contents of danji radish was significantly higher than other samples.
Crude protein of danji radish and winter radish, which radish leaves harvested intervals of about 30days from Dec.15 were 2.8~4.3% and 2.4~3%, respectively. In case of radish leaves as much as radish, Vitamin C contents of danji radish was significantly higher than other samples.
The research for the productivity of baby vegetable production used by Danji radish seed compared to local market vegetable. The seed of danji radish, radish, jeju barley, halla rape, broccoli and red mustard were purchased from a local market. lt produced the baby vegetable with the seed. The sprout rate of danji radish, radish, jeju barley, halla rape was almost 99% and that of broccoli and red mustard was 3% lower than that. lt took 5 days for radish to sprout, 6 days for danji radish, broccoli and halla rape, 7 days for red mustard, and 10 days for jeju barley.
These results showed that content of vitamin C was 52.9mg for Broccoli, 45.4mg for radish, 44.9mg for halla rape and 43.3mg for danji radish. The content of total phenols was 316mg/100g for radish, 238mg/100g for broccoli, 227mg/100g for danji radish and 188mg/100g for red mustard. The antioxidant activity of baby vegetables was evaluated based on its potential as a scavenging stable DPPH radical. Results showed the antioxidant activity was higher at broccoli, radish, danji radish and halla rape in the baby vegetables.
When danji radish seed was seperately preserved at normal temperature for 90 days, 0℃ and 4℃ for 180 days and 10℃ for 270 days, It was harvested best at 0℃ and 4℃. Furthermore, baby vegetable preserved at 0℃ have less amount of nitrogen than other baby vegetable, but more amount of phosphoric acid, calcium and iron.
To large-scale market, baby vegetable is delivered through direct management. Then, at large-scale market, packs of 500g are distributed to restaurants and packs of 50g are distributed to consumers on the spot. On the other hand, to small and medium scale market and restaurants, radish baby vegetable is delivered through the public management and distributed to consumers. In addition, the original country of radish baby vegetable seed is 100% U.S.A.
We developed two types of baby vegetable cultivation machines. First, cabinet-type baby vegetable system is divided into 3 parts. The principle is that you divide prodution console into three parts and install spray nozzle at the upper part, the electron valve at the supply part. Then, it can operate by the signal of control part. Second, temperature control type baby vegetable cultivation machines operate by installing cultivation machine, water tank, control part, water supply motor. when you connect water tank with cultivation machine through a hose, it provides water by the control of a timer control. In addition, it can adjust temperature.
If you want to harvest large amount of baby vegetable by hydroponics, you can choose spray water hydroponic growing. Install styrofoam at the upper part of growing bed and make hole as S/T basket can take place. Then, place seed in the S/T basket. As the result of the research for ingredient of hydroponics baby vegetable 100g, it contains 28.24mg more vitamin C than radish baby vegetable of sale at a market and far more calcium, iron than that. Also, owing to the culture solution, it contains a little more nitrogen than baby vegetable of sale at a market. To sum up, using spray water hydroponic growing, you can harvest baby vegetable not only at large amount but also for good quality.
