Seven ways to make carrots produce good seedlings
1. Seed treatment When buying seeds, try to use treated light seeds. If it is a hairy seed, rub the bristles off the seeds first when sowing, so that the seeds are closely connected to the soil and absorb more water to facilitate germination.
2. Apply enough base fertilizer to apply more than 2500 kilograms of decomposed high-quality organic fertilizer and more than 50 kilograms of three-element compound fertilizer per acre to prevent and control underground pests.
3. After the fine soil preparation is finely crushed by tillage and rake, it is made into a border surface of 2 to 2.5 meters, and then no-tillage is used again with a no-tillage drill to achieve fine and loose soil.
4. Suitable moisture sowing According to the soil moisture, sowing immediately after irrigating and swelling in a drought. After sowing, use a six-tooth harrow to cover the seeds. Generally, new seeds of the year are used, and 0.5-0.8 kg of light seeds are required per mu.
5. When planting vegetables and shading, mix a small amount of green vegetables and sowing at the same time, and use the characteristics of green vegetables to emerge and grow quickly for shading. After the carrot seeds emerge, the green vegetables are harvested in time to market, which can not only play the role of shading the emergence, but also improve the land utilization rate.
6. After the chemical weeding carrots are sowed, if the weeding is not timely, they will form silly seedlings. Therefore, after sowing, use 100-150 ml of Shitianbu or napropamide EC for chemical weed control per acre.
7. Cover grass moisturizing after sowing, cover an appropriate amount of short wheat straw on the border surface, which can not only protect the seedlings from emergence, but also prevent the soil from being washed by rain.
