1, choose a good seed. Selection of high temperature, high yield stability, good quality red reputation five inches. The variety is grown in Daxie Shayuan without twitching, and is normally developed. The amount per mu is 150-200g.
2, choose fertilization. The off-season carrots are suitably the same as the autumn and winter carrots, and it is appropriate to use sandy loam soil and loose silt.
For fertilization, soil fertility should be used to determine the amount of fertilization. In general fields, base fertilizer should be used as the main fertilizer, and 3,000 kilograms of organic manure (20 kilograms of diammonium phosphate, 10 kilograms of urea) and 10 kilograms of potassium sulfate. When ground pests were found, 2 kg of 3% carbofuran granules were used before turning to the ground. In order to prevent the occurrence of weeds, Mushi 48% trifluralin 80 ml, spraying the ground with water, turning the floor 25 cm deep, try to loosen the soil. Build a 120 cm wide, 30-50 cm long slug. If soil is lacking, it can be watered and then soiled.
3, timely sowing. When the 5 cm ground temperature is stable above 12°C, the daily average temperature reaches 14.5°C, and the seeds can be sowed. The eastern part of Shaanxi Guanzhong is suitable for April 5-10.
Seeds soaked in warm water for 12 hours before sowing, remove the sand, the ratio of species of sand is 1:6, in order to uniform the species can also be used to rake the sand, with open ditch (wood beam on security three bamboo pieces, bamboo spacing is 20 Centimeter, bamboo thickness 0.8-1 cm, length 20 cm, width 3 cm wide, width 2 cm wide) Open ditch 0.5 cm deep, along the ditch sow, after the species along the ditch stampede, and then push North
Pull it over again to level the ground. It can also be used for filming, high height ridges of 5-8 cm, 40 cm wide under the ridge, 25 cm wide, and 50 cm from the center of the ridge. On the ridges, 2 lines are planted on the ridge, with a spacing of 18 cm and a spacing of 10 cm. Then cover the film (with mulch film) film width 40 cm, seedlings promptly after the emergence of seedlings. With this kind of planting method, the bottom water should be filled.
4, post-plant management. 4 leaves before and after the Dingmiao seedlings, drilled spacing of 12-15 cm, 23,000 acres of left seedlings. After entering the month of May, the temperature rises. When the water is dry in time, combined with irrigation, the cultivator shall loosen the soil in time to remove the weeds, so that the ground will always remain loose and non-stuck.
