Hongying No. 2 Carrot is a new variety introduced from Japan. It has been promoted in Jiangsu, Hebei, and other provinces in the past two years. The variety is high in yield, quality, and has good merchandise. It can produce more than 4,000 kilograms per acre, which is used for fresh food and processing. Type of ideal species, the economic benefits are considerable. The cultivation techniques are as follows: 1. Selection of land and site preparation. Choose sandy loam soil with deep soil, loose soil, convenient drainage and irrigation. Before the harvest, combined with ploughing Mushi 3000 kg of organic fertilizer, 25 kg of superphosphate, 25-30 kg of compound fertilizer as base fertilizer. 2, germination sowing. Seed soaking after sowing, can be early emergence of 5-6 days, significant increase in production. The method is: soaking with warm water 30-35 °C for 3-4 hours, remove and put it in a wet cloth bag, put it at 25-30 °C, germination for 3-4 days, during which flush with water once a day to keep the seeds moist, regular Stir and make the temperature uniform. After 80-90% of the seeds are white, mix them with wet sand. 3, cultivation methods. In the spring, the seedlings were planted with alfalfa; in the summer, the alfalfa cultivation was carried out. It is better to use double row rows of large ridges for field management and weeding and weeding. Spring sowing is generally bud sowing, line spacing is 25 cm 8-10 cm, Mu 35,000 seedlings seedlings; summer seeding is generally dry seed live, line spacing is 25 cm 10-12 cm, Mu Bao seedlings 2.7-3 million. Mu with 300-500 grams. After sowing, the cover soil should not be too thick and be repressed to facilitate the unearthing of the seedlings. Mowing and weeding should be carried out early and the cultivator should be shallow to avoid damaging the roots. In order to prevent the formation of grassland in large-scale cultivation, weeding can be used before the emergence of seedlings, so that we can save time and labor. Use 33% of weeding and 80-100 ml of water to spray 50 kg of water, or 50% of phragazide 450 g to spray 75 kg of water. 4, fertilizer and water management. During the seedling stage, the proportion of nitrogen, phosphorus, and potassium fertilizers was adjusted according to the growth conditions. Nitrogen fertilizer should not be too much, so as not to affect the root swelling and coloring, and more phosphorus, potassium fertilizer, it is conducive to root enlargement and coloring. The first time in the 5-6 days after the start of seedlings, combined with water mus ammonium sulfate 2-3 kg, superphosphate 3-3.5 kg, potassium fertilizer 1.5-2 kg. The second top-dressing is applied at the true leaf stage of the plant with 8 to 9 pieces, that is, the initial period of fleshy root enlargement is the period with the most need of water and fertilizer, and the soil should be kept moist. During this period, 7 kg of ammonium sulfate, 3 kg of superphosphate, and 1 kg of superphosphate are used. 3-4 kg. Irrigation in spring should be timely to prevent drought; irrigation should be properly cultivated in summer to prevent flooding and flooding. Soil cultivation combined with cultivator to prevent fleshy roots from exposing to the ground to form green shoulders. 5. Pest control. The variety has strong disease resistance, and has less pests and diseases in cultivation. To prevent root rot, 50% carbendazim can be used for soil treatment before sowing. It is better to work with grass crops for 2-3 years. 6, timely harvest. The specific harvest time is based on the full expansion and maturity of fleshy roots. Spring sowing is generally started 80-90 days after sowing, and summer sowing is usually started 90-100 days after sowing.
