Beet is a two-year cash crop. In the first year, it mainly carried out vegetative growth, forming luxuriant foliage and hypertrophic main roots (roots), and accumulated a lot of nutrients in the tuberous roots to prepare for entering reproductive growth. In the second year, reproductive growth was mainly carried out, and seeds were formed by twitching, flowering, and fertilization. The growth habit of sugar beet and its absorption of nutrient elements can be divided into four stages: seedling stage, rapid growth stage, root sugar stage and sugar accumulation stage. 1, base fertilizer Beet base fertilizer mainly organic fertilizer, with a certain amount of fertilizer. Basal fertilizer should be applied in combination with ploughing and soil preparation. Before turning the soil, organic fertilizer and chemical fertilizers are mixed and evenly spread on the ground. After that, the machinery is ploughed; in the ridge area, basal fertilizer is applied to the ridges in combination with ridging. 2. Seeds of seeded sugar beets are less seeded and contain less nutrients. Therefore, applying microbial inoculants as seed fertilizer during sowing can significantly promote root development of the seedlings, enhance absorption capacity, and enhance seedling resistance to cold, drought, and disease resistance. 3. The frequency and amount of top-dressing top dressing should be determined according to the soil fertility, the amount of basal fertilizer and seed fertilizer, and the growth of sugar beet. The general fertility medium, the base fertilizer Mushi organic fertilizer 1500-2000 kg, a better growing land, in the leaf from the lush period, acres of 1 times topdressing urea 10-20 kg. Insufficient basal fertilizer, poorly growing plots or high-yield fields, can be applied twice, the first time in the Dingmiao Mu topdressing urea 5-l0 kg, the first time in the ridge before combining the cultivator Mu Mu urea 5 - L0 kg. Topdressing 3 to 5 centimeters from the sugar beet seedlings, plan a 5 to 7 cm deep pit with a hoe and apply it to the top dressing. 4. Top dressing with foliar beet dressing can increase root yield by about 10%, sugar content by 0.2-0.8 degrees, and sugar production by 10-15%. Especially in the growing period of sugar beet root sugar, the effect of foliar dressing is the most significant. For foliar dressing, we must strictly control the concentration of fertilizer solution. The general potassium sulfate should be in the 0.6% -1%, superphosphate in 2% -3%, potassium dihydrogen phosphate in 0.2% -0.3%. Fertilizer consumption should also be based on the size of the leaf clumps. Spraying less at the seedling stage, the leafy lush period can be more, generally 20-40 kg per mu. The growth of sugar beet mainly lacks boron and zinc. After the sugar beet is ridged, it is sprayed once every 2 weeks with 0.1% boric acid solution 40-50 kg and sprayed 2-3 times. Boron-poor areas, spraying boron immediately after settling, in order to prevent premature aging of beet leaves or heart rot symptoms. Zinc fertilizer can be supplemented with seed fertilizer or foliar spray. Fertilizer Mushi 500-1000 grams of zinc sulfate, or soaked with 0.1% zinc sulfate solution. After the sugar beet is ridged, the mu is sprayed with 0.1% zinc sulfate solution 40-50 kg leaf surface.
