Spring carrot cultivation techniques

1. Variety selection Spring carrots should be selected for short growth period, late bolting, cold-resistant, heat-resistant and disease-resistant varieties. At present, most of the spring carrots cultivated in China are imported from abroad, mainly including the five-inch red reputation of Japan, the five-inch star of Xinxingtian, the five-inch summer time, and the five-inch gold harbor.
2. Soil fertility for soil preparation: Choose fertile soil, deep loose soil and well-drained loam or sandy loam soil. Apply 250,000 to 3,500 kilograms of decomposed manure, 4000 to 5,000 kilograms of compost, 40 to 50 kilograms of compound fertilizer, and plow 25 centimeters before planting.耙 整 整 整 整 整 整 整 整 畦The northern areas with low rainfall are generally cultivated with flat ridges. The buckwheat noodles are 1 to 1.2 meters long, and the pods are 25 centimeters wide and 20 to 25 centimeters high. In the rainy areas in the south, sorghum is used for cultivation.
3. Appropriate sowing early spring carrots require stricter sowing time, easy to twitch prematurely, and high temperatures late in the late period are not conducive to the growth of fleshy roots. Spring carrots are made of leather, densely bred, and the bristles on the seed coat should be plucked before sowing. Sunny seeds are 1-2 days, soaked in warm water of 25-30°C for 5-6 hours. 10 hours, then sowing.
4. Management after sowing (1) Use of herbicides The density of spring carrots is large, and the growth of seedlings is slow. When the weeding costs are paid, the herbicides should be used in time after sowing. Generally use 50% paraquat 100 grams, about 70 kg of water sprayed on the ground, can also be used 25% herbicide ether 0.75 to 1 kg per mu, about 150 times dilution of water, spraying soil surface, can control a variety of annual weeds. After emergence, 10.8% Gaifu can be used. The dosage is 20 ml per acre, spraying 30 kg of water to remove monocotyledonous weeds.
(2) Spring seedlings and Dingling Spring carrots are usually subjected to two seedlings at the seedling stage. For the first time in 1 or 2 true leaf stages, except for crowded shoots, spacing between 3 and 5 cm, and intercropping between the rows; in 4 to 5 true leaves, 2 seedlings are to be seedlings, and the inferior and diseased plants are removed. And dense strains, spacing 10 to 12 cm, leaving about 60,000 plants per mu. Two times of shallow cultivating and weeding were carried out in combination with Dingmiao.
(3) Fertilizer and water management Spring carrots germinate and seedlings are at early spring and low temperature. They are not particularly arid and generally not watered until they break the belly stage (5 to 6 true leaves). Ammonium sulphate or urea 10 to 15 kg, or 1000 kilograms of human excrement. 7 to 8 true leaves grow vigorously on the ground, to properly control the water, to strengthen the cultivator loose soil, promote the main root extension and fibrous root development, to prevent the prosperous leaves. When the fleshy root finger thickness, has entered the rapid expansion period, when the external temperature rises, the plant consumes more water, watering in time, and combined with watering for top dressing. With the principle of groundwater pouring, the soil is often kept moist. During this period, the soil is too dry to cause fleshy roots to be corked, and lateral roots are increased; when the moisture is too much, the meat is rotted; dryness and dampness cause flesh cracking, which reduces the yield and quality.
