On-site management:
1, early seedling, late seedling.
When the true leaves of 1 are unfolded, the seedlings can be thinned, the weak seedlings, deformed seedlings and mixed seedlings damaged by diseases and pests can be pulled out, and 3-4 seedlings are left in each nest; When the belly was broken, two strong seedlings with the characteristics of the original variety were selected. Early plant spacing is conducive to the growth of seedlings and the formation of robust seedlings, and late planting is conducive to the neatness and integrity of seedlings.
2. Scientific fertilization.
① Apply sufficient base fertilizer. Before sowing, use/kloc-0.5 kg of calcium superphosphate and 7.5 kg of potassium chloride as base fertilizer per mu, mix them evenly and apply them centrally. After sowing, apply decomposed human and animal manure as seed covering fertilizer.
② Rational topdressing. Topdressing 2~3 times, mastering the principle of light before and light after. 1 period, about 25 days after sowing (big belly-breaking period), spraying decomposed human and animal manure 1000 kg and urea 3 kg per mu; The second time, 45 days after sowing, sprayed with 1000 kg of decomposed human and animal manure and 5 kg of urea; The third time, about 65 days after sowing, fertilize the seedlings. Adding organic fertilizer can promote high yield and high quality of carrot.
3, intertillage weeding.
In case of mulberry soil hardening, intertillage 1~2 times is appropriate. Weeds should be cleared in time in each growth period, which is beneficial to photosynthesis and pigment accumulation, and at the same time, it can reduce the humidity of border and reduce the harm of pests and diseases.
