What are the characteristics of the three common carrot varieties?
The carrot is an extremely common vegetable, rich in vitamins and slightly sweet, and very popular with many people. At present, there are three relatively common carrot varieties on the market: Hongying No. 2, Mendel, and Tianhong No. 5. You may find the names unfamiliar, but you have probably seen them often. They each have different characteristics, and next the editor will introduce them to you!
What are the characteristics of the three common carrot varieties:
1. Characteristics of Hongying No. 2
Hongying No. 2 is a first-generation hybrid variety bred by Marutane Co., Ltd. of Japan. It is mainly used for spring planting, and can also be planted in summer and autumn.
(1) This carrot has a growing period of 80~90 days. The plant has an upright leaf cluster, and the leaves are dark green. The root skin, flesh, and core are all orange-red, cylindrical in shape, with a root length of about 18 cm, a root diameter of 4.8 cm, and a root weight of 200~250 g. The total soluble sugar is 4.92%, and the beta-carotene is 40.4 mg/kg. This variety has particularly uniform root shape, a very smooth skin, and characteristics such as resistance to bolting, early maturity, high yield, and a very high rate of marketable roots. It is suitable for close planting, and the yield is very high.
(2) The most suitable sowing time is when the local soil temperature at a depth of 5 cm is stable at 8°C~15°C. It is suitable for planting in the north. The Beijing and Tianjin areas are suitable for mid- to late March, southern North China is suitable for late February to early March, and high-cold areas such as the northwest and northeast can be sown from early April to mid- to late May. The sowing rate is 300~500 g per 667 sq m, with 30,000 seedlings retained per 667 sq m.
2. Characteristics of Mendel
Mendel carrot is a new first-generation hybrid variety bred in Japan, suitable for planting in protected areas in early spring and in open fields in summer and autumn.
(1) Mendel's growth cycle is 90~130 days. The root is cylindrical, with a root length of 18~22 cm, a root weight of 200~300 g, and a root diameter of 4~5 cm. The average yield per 667 sq m is 3,500~6,000 kg.
(2) It is suitable for planting in East China, North China, and other areas. Shandong is suitable for spring sowing from January to March. The sowing rate is 200 g per 667 sq m, sown on ridges. With reasonable close planting, 28,000~30,000 seedlings are retained per 667 sq m. This variety's roots expand particularly quickly. For summer and autumn sowing, it should be sown appropriately later, about 7 days later than other varieties.
3. Characteristics of Tianhong No. 5
Tianhong No. 5 is a new first-generation hybrid variety bred by the Tianjin Academy of Agricultural Sciences. It is mainly used for spring planting.
(1) Tianhong No. 5 has a growing period of 100~105 days. It has strong growth vigor, a plant height of 62.22 cm, 10 leaves, and a very upright leaf cluster. The fleshy root has a uniform root shape, smooth skin, cylindrical form, orange-red color, and a relatively thin core. The average root length is 14.47 cm, the root diameter is 4.06 cm, and the root weight is 106.92 g. The carotene content is 70.28 mg/kg fresh weight, and the soluble solids are 9.11%. The average yield per 667 sq m is 3,207 kg. The maximum bolting rate for spring sowing in greenhouses is 0.26%. It is tolerant of low temperatures and resistant to bolting, making it a relatively ideal new carrot variety for spring sowing.
(2) It can be cultivated all over the country. In Tianjin and surrounding areas, heated greenhouses and conservatories are sown in early February, plastic greenhouses (with plastic film mulch) are sown in late February, and plastic film mulching cultivation is sown in late March. The sowing rate is 300~400 g per 667 sq m. The plant and row spacing is 6~8 cm x 30 cm, with 30,000 seedlings retained per 667 sq m. In plastic greenhouses or conservatories, ventilate at noon when the temperature is high. When the plant environment temperature reaches 18°C, close the vents in time to reduce the risk of bolting, and harvest and sell promptly.
