Cultivation of Imported Vegetables Red Head

Red cabbage, also known as flame vegetable, is a red root beet, which is mainly eaten as a spherical fleshy root and is one of the main vegetables in Europe and the United States. Beetroot is a biennial herb of the family Polygonaceae. It is native to the Mediterranean coast. Its fleshy root color is bright, with less cellulose, soft texture, rich nutrition, in addition to the use of vegetables, as well as the treatment of vomiting and diarrhea, disperse the parasite in the digestive tract, treatment of hypertension and other effects. First, the main characteristics of the characteristics of red head is a straight root crop, the growth of the first year of the formation of rosettes and fleshy roots. The shape of the fleshy roots varies, but the oblate shape is the best. The skin and fleshy roots are purple. There are several circles of dark purple concentric rings in the cross section of the fleshy root. Therefore, the western food also serves as a potted dish. In the second year of May, the height of the stem and stem is about 110 cm. Red cabbage head is a cold-tolerant plant, like the cool climate, the optimum temperature for the growth of the leaves is 13-18°C, and it is not tolerant to high temperatures. The plants are at a temperature of 22°C or more and the fertility stops. The optimum temperature for seed germination is 15°C. When the plants are overwintering, they pass the vernalization stage for 30-80 days under the temperature of 2-6°C, and then they twitch and flower under warm long-day conditions. Germination of seeds or seedlings at a temperature of 4 to 10°C for more than 15 days can be used to draw stems. All kinds of soil can be cultivated, but the most suitable soil is moist, loose and fertile, well-drained alluvial soils and sandy loam soils, and the soil is neutral or slightly acidic. Second, many varieties of cultivation are introduced from abroad, such as Ryukyu, Detroit Red and so on. Spring sowing and autumn sowing are all available. Spring sowing is scheduled to be harvested from March to April and from May to June. Autumn sowing can be harvested from July to September and from October to the following March. After finishing, apply the basal fertilizer to the seedlings on the seedlings or sowing seedlings, drilled at a distance of about 40 centimeters, sowing depth of 2.5 to 3 centimeters, and the seed amount of 1 to 1.5 kilograms per 667 square meters. When sowing can be added seed weight 3% - 4% of small radish seeds mixed into the field. Appeared about 10 days after sowing. Seedling 1 - 2 true leaves time seedlings, seedlings from 3 - 4 cm; 3 - 4 true leaves when the Dingmiao, seedling distance 6 - 8 cm. Between 667 m2 and 1,000 kg of diluted manure water after the Ding Miao. In the absence of boron in the soil, it can easily cause black spot, resulting in thin or deformed leaves, hard masses in fleshy roots, or spreading dark spots in cork. For boron-depleted fields and borax 0.7--3 kg per 667 square meters. General sowing 60 - 100 days after harvest, 667 square meters of production 1000 - 1500 kg. When harvesting in autumn and winter, plants with the characteristics of this variety, no pests, and no damage were selected as the seedlings, and the leaves were cut and then planted in the reserved field at 70 cm X 50 cm. The seed matures from June to July in the following year, and about 50 kilograms of seeds can be harvested per 667 square meters.

PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. PGA is a sticky material first found in "natto", a fermented soybean. PGA is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.
Gamma-poly-glutamic acid (gamma-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer.

It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
