What should summer carrot plant notice?

What should summer carrot plant notice? Please give an introduction to summer carrot cultivation can refer to the following methods: first, fine soil preparation carrots are meat root vegetables, like deep and loose soil. Land preparation should be ploughed deeply, with a depth of not less than 30 cm. To achieve intensive cultivation, to achieve fine broken soil, flat ground, good soil moisture. It is best to form a border 2 to 2.5 meters wide to facilitate drainage and irrigation. In order to prevent the problem of burning seedlings of organic fertilizer, full ripening and mashing should be carried out before fertilization, and combined with soil preparation, 2500-3000 kg of rotten organic fertilizer and 50-80 kg of ternary compound fertilizer should be applied per mu. Control of underground pests in order to control the harm of underground pests, an appropriate amount of insecticidal pesticides are mixed into organic fertilizer, which has a good effect on the preservation of seedlings. Fourth, the seed treatment will first rub off the bristles on the dried seeds to facilitate the close connection between the seeds and the soil. Soak the seeds in 40 ℃ hot water for 30 minutes before sowing, then add cold water to lower the water temperature to 20 ℃ ~ 25 ℃, soak for 24 hours, wait for the seeds to fully absorb water and remove them for germination. The suitable temperature for sprouting is 20 ℃ ~ 25 ℃. When more than half of the seeds show small buds, they are sown in time. The experiment shows that if the seeds are sown after treatment, the seedlings can emerge 2-5 days earlier, and the seedlings will emerge 6.4%-9.6% more. Fifth, the timely application of pre-budding herbicides after chemical weeding, sowing and covering soil, not only avoids a large amount of manual weeding, but also has a good weeding effect. Herbicide varieties such as Liguron, Shitianbu and Diachlor, which are safe to carrots and have good herbicidal effect, can be selected. With herbicide EC 100ml / mu and 60kg / mu of water, the ground was evenly sprayed, and the weed control effect was more than 95%. 6. after spraying herbicide, cover the border with a layer of short wheat straw 2cm to 3cm thick, which can not only prevent the emergence of seedlings caused by heavy rain, but also protect the sun and preserve soil moisture so as not to cause seeds to dry, and mulching has a good effect on the preservation of seedlings.
