First, cultivated varieties
1. Takasaki Kuroda Five-inch carrot Japanese imported varieties, neat roots, average length 20 to 22 centimeters, crude 4.5 centimeters or so, rarely cracked roots, roots and shoulders in the small sharp tail, roughly cylindrical, color thick red , Red meat, red skin, disease resistance and heat resistance, suitable for spring and autumn sowing, about 110 to 120 days after sowing, fleshy root weight of about 300 grams, 1/15 hectare production of more than 8000 kilograms, is a high-yield varieties, than the general The new Kuroda ginseng carrots have the outstanding advantage of having a small root and shoulder; there are many sugars, and the output is high and it is a new type of processed and dehydrated carrots.
2. Super Kuroda ginseng is introduced from Japan and has strong heat resistance. It is suitable for sowing in spring, summer and autumn. It is harvested 100 to 110 days after sowing. It grows robustly, its roots are cylindrical, orange red, roots are 22 cm long and weighs 300 grams. , High production, good merchandise, suitable for export processing.
3. Japan's Hong Yongren No. 2 Japan imported varieties, plant height 48 cm, degree of development of 56 cm, more upright plant shape, not easy to shade each other, small leaves, light green, anti-blow leaf blight. The total number of leaves per plant is 14 to 16, the root length is 18 to 20 cm, and the root mass is 200 to 250 g. The shape is nearly cylindrical, and the ending is good. The skin and fruit are rich in red, and the rate of three reds is high. The taste is good. Storage and transportation, good merchandise, not easy to appear due to rooting caused by the Qingtou phenomenon. The growth period is 105 days and the yield reaches 2650.1 kg per 1/15 ha.
4. Super sweet carrot small raw food, root cylindrical, 60 to 80 days after sowing harvest, root length 12 to 14 cm, roots 1.3 to 1.6 cm, root weight 20 to 25 grams, bright red flesh , fine meat, sweet and crisp, is the beauty and health food on the table.
5. Red heart seven inches in the United States imported, late-maturing varieties, skin orange, single root weight 300 to 500 grams, length 20 to 25 cm, diameter 7 to 9 cm, good quality, widely planted in China, performed well.
Second, the cultivation of carrots is a semi-cold vegetables, fleshy root hypertrophy suitable temperature is 18 ~ 25 °C. Spring sowing is easy to twitch prematurely; too late can easily lead to a large number of deformed roots. According to the production experience, it can be sown at a daily average temperature of 10°C and a nighttime average temperature of 7°C.
Carrot production and supply patterns in northern regions
Crop cultivation and methods Sowing period Harvest period
Spring mulch with small arch sheds from late January to early February and late April to early May
Spring mulch late February - early March late May - June
Spring exposing area from late March to early May from June to July
Autumn in June - July, October - November
Third, soil preparation for the selection of deep soil, drainage and irrigation facilities, rich in organic matter, loose air permeability of the sand field block planting. Plowing winter hoe, plowing more than 25 cm deep, 2500 kg per 1/15 ha of cooked manure, 20 kg of superphosphate, 25 kg of potassium chloride or 100 kg of high-quality compound fertilizer. Cargo avoid water, you must do it, to ensure smooth drainage. After the basal fertilizer is applied, the squat is 120 centimeters wide. Between each squat, a ditch with a depth of about 20 centimeters is left. For every two rakes, a ditch with a depth of 33 centimeters is to be dug. Every 30 meters, a deep 67 centimeters of waist is to be dug. Ditch, field head dig deep 100 cm drainage ditch, reach irrigation, row out, drop down.
Fourth, germination sowing carrot seeds is not easy to absorb water and breathable, coupled with the weather when planting is not appropriate, resulting in seed germination and seedling slow. In order to promote early germination and emergence of seedlings, germination should be carried out before sowing. Germination method, in addition to warm soup soaking, and then introduce a new germination method, that is, alternating wet and dry. The carrot seeds are placed in the container, the amount of which is not more than 2/3 of the container, and 70% of the seed weight is sprinkled in the container, and the mixture is fully stirred so that the seed is soaked with water, and the seeds are closed for 24 hours, and then the seeds are tiled. In the newspaper, let it dry indoors. Wet and dry treatment takes about two days at a time, so it is better to treat it 2 or 3 times. After processing, seeds can be directly broadcast into Daejeon. If seeds cannot be sowed for the time being after treatment, the seeds can be prolonged for 1 to 2 days after the last natural drying. Store up to 40 days. After treatment, the seeds germinate early, germination rate is high and emergence is neat. Seeding can be broadcast, on-demand, or broadcast, preferably using drills. Open the ditch before sowing, the ditch should be straight, the same depth, 1 cm deep. If the sensation is not good, artificial pods should be planted, cover soil 0.5 to 1 cm, gently suppress, herbicide should be sprayed in time after sowing. In addition to lice and cockroaches, poisonous baits can be used to trap and kill.
V. Field management and harvesting When the cotyledons are unearthed, the first time the seedlings are planted, the seedling distance is 3.3 cm. When the seedlings have 3 to 4 true leaves, the seedlings are seeded and the seedling distance is 10 cm. The top dressing is generally divided into two, and each can be chased once after settling and when the fleshy roots are swollen. Each time 1/15 hectares of potassium sulfate compound fertilizer 10 kg. If the weather is particularly dry, it should be properly watered. The amount of water should not be too large to facilitate seedlings. In the late growth period, if there are too many weeds, weeds can be sprayed with special herbicides. After cultivating the seedlings, cultivating loose soil. In the later period, combine the cultivator with soil, or smash the roots with fine soil to prevent green roots. If pests can be sprayed pyrethroid pesticides. After the carrot grows to the appropriate size, it can be harvested according to market conditions and needs.
