1 Site preparation
Land preparation is carried out on the basis of deep plowing or deep loosening. Level the ground, loosen the soil, and preserve moisture. The best place is to use the diagonal and horizontal landscape.耙 耙 deep 4 ~ 5 cm, generally 耙 1 ~ 2 times, the plots of more land should increase the number of depression. In short, it is necessary to achieve soil crushing, loosening, insulation, and water retention to provide suitable seedbeds for beet seeds. The best time for spring soil preparation is to turn the soil back to the soil during the soil re-slurry period, so that it can be turned over, smashed, and pressed for continuous operation, and it ends before re-slurry.
2 ridge work
The first ridge after sowing is a typical form of ridge beet. During the ridging period, it is best to volt (summer) tilling autumn ridges; followed by autumn ploughing and autumn ridges; late for ploughing and soil preparation, spring ridges can be adopted. In order to prevent the soil from running, ridges and repression should be performed continuously. . The row spacing of sugar beet ridges is generally 60-66 cm, and where there are conditions, 50 cm row spacing should be promoted. This is one of the effective measures to increase the number of sugar beet plants per unit area and increase yield and sugar content. The ridge height is generally 12-15 cm.
3 Seeding
On-demand broadcasting is a widely used sowing method in ridge cultivation areas. That is, on a well-developed ridge, seed holes (about 5 cm in depth) are drilled at a spacing of 25-27 cm, and 6-8 seeds per hole are sown, and then the farmhouse fertilizer is applied. If chemical fertilizers are applied, they should be applied 3 to 5 cm below the seeds. In order to facilitate seed germination, when the soil is dry, the bottom grid should be stepped on before sowing (that is, lightly stepping on the toes inside the hole); when severe drought occurs, the method of “doing water pod breeding†should be adopted. Fertilization, watering, sowing, and soil repression.
The thickness of the cover soil should be determined according to the quality of soil preparation and soil moisture. For soils with good site preparation quality and suitable humidity, the cover soil thickness is generally 3 to 4 cm; if the soil is heavy and the water content is large, it can cover 2 to 3 cm; and when the soil is arid, it should be 4 to 5 cm.
After sowing, in order to make the seeds of sugar beet in close contact with the soil and to facilitate the increase of the moisture in the lower layer of the soil, repression should be carried out in emergency. The time, frequency, and severity of repression must also be determined based on soil porosity and moisture content. If the soil is more viscous and has a higher moisture content, it can be gently suppressed or repressed after a few days; conversely, if the soil is loose, the porosity is large, and when the climate is dry, it should be repressed immediately after sowing, and the degree of heavy some.
4 Beet Fertilization Technology
4.1 Base fertilizer
Known as base fertilizer, it is the most basic fertilizer for sugar beets. Basal fertilizers are mostly farmyard fertilizers, ie organic fertilizers such as manure, compost, and green manure, or a certain amount of inorganic fertilizers (generally 2/3 of the total fertilizer is used as base fertilizer). Phosphorus fertilizer as a deep application of basal fertilizer, favorable phosphorus distribution in the root-dense area, improve the utilization of phosphorus; potassium as a deep application of base fertilizer can reduce the loss of available nutrients, but also reduce the adverse effects of deep nitrogen accumulation in soil. The basal fertilizer is applied to the ridges in combination with ridging.
4.2 Fertilizer
Beet seeds are smaller in size and contain less nutrients. Because of the cultivation techniques of winter peppers, seedlings (mainly seeded) do not have to be supplemented with certain nutrients, and the seedlings will grow very weak and resistant to wind damage and disease. Experiments have shown that the application of phosphate fertilizer as a seed fertilizer can significantly promote the development of seedling roots, enhance the absorption capacity, and enhance the drought resistance, cold resistance and disease resistance of seedlings. In the saline-alkali land, using calcium superphosphate as seed fertilizer can both neutralize the alkalinity of the soil, reduce the salt and alkali damage, and improve the structure of the soil. Fertilizer dosage can not be too much, it is generally 1/4~1/3 of the fertilization amount in the whole growth period. Moreover, the type and amount of specific sugar beet seed fertilizer must be determined according to the soil nutrient content, so that what elements are lacking will be applied. What fat. In medium-fertility plots, general phosphate fertilizers are used as seed fertilizers with an application rate of 2 to 4 kg per mu, and nitrogen fertilizer should be less than 5 kg per mu. When using chemical fertilizers, be sure to apply 4~5 cm below the side of the bulb, and do not make direct contact with the bulbs to avoid “burning†and ammonia poisoning.
4.3 Root dressing
Topdressing is a quick-acting fertilizer that is supplemented when there is insufficient or no element in the growth phase of a beet. In the land where water and fertilizer are easily lost, fertilizers should be applied in a timely manner. Topdressing with nitrogen fertilizer, with appropriate amount of phosphate fertilizer.
The period of topdressing is mainly after the seedlings reach the period of luxuriant foliage. At this time, the nutritional demand for sugar beet increased sharply, and the basal fertilizer effect had not been fully realized. The nutrients for the seed fertilizer had been consumed in large quantities, and quick-acting nutrition should be added in time. Note that the topdressing period should not be too late, so as not to cause excessive growth of sugar beet stems and leaves, affecting tuber yield and sugar.
5 Disease Prevention and Control
5.1 Beet Blight
The control of sugar beet blight is mainly to treat the seeds with fungicides and to cooperate with corresponding agricultural technical measures. The first is the pharmaceutical treatment seed. With 0.8% of thiram seed dressing or enemy, that is, per 100 kg of seeds, immersed in 0.8 kg of 50% thiram or 95% dexamethasone wettable powder seed dressing, the control effect of up to 60%. The second is agricultural technology measures. In order to implement a reasonable crop rotation, it is best to choose cereal crops as the front hoe and not use vegetable vinegar to prevent the beetroot from picking up and picking up the pods. Fine arable land, timely sowing, soiling should not be too thick (3,4 cm is appropriate), prompting seedlings earlier unearthed. Timely loose soil, remove the hardened layer and increase ground temperature.
5.2 Beet brown spot
Sugar beet brown spot, also known as leaf spot disease and spot disease, is a worldwide disease that seriously damages the production of sugar beet. It occurs in various parts of China. In general, the production of roots can be reduced by 10% to 20%, and the sugar content can be reduced by 1 degree. In serious cases, the yield can be reduced by 40%, and the sugar content can be reduced by 2 to 3 degrees. Control methods: Beet brown spot is an epidemic disease caused by a variety of etiological factors, so single prevention and control measures are difficult to control effectively. It is necessary to adopt a combination of disease-resistance cultivars, combination of cultivation techniques, and chemical control measures to achieve effect. Strict implementation of four years or more rotation. The land of sugar beets must not be heavy or beggars, and the plot should be kept away from the land of beet (500-1000 m) last year to prevent the spread of germs. Thoroughly clean the sick stems and leaves in the field.
6 Harvest
6.1 Harvest period: The suitable harvest period of sugar beet is from late September to mid-October. When the functional leaves of sugar beet declined in large quantities, the stems and leaves drooped, the field turbulence disappeared, and large lines cracked. The long-leafed leaves evacuated and everted, the leaves became pod-shaped, the leaves turned yellow, and there was a bright luster. During the mature period, it should be timely and timely harvest.
6.2 Harvesting methods: (1) Mechanical harvesting: After harvesting the drip irrigation belt, a special beet harvester is used to harvest, cut, and load the car at one time. (2) Man-Machine cooperation with harvesting: The use of mechanical lifting, manual picking and cutting, required to achieve "four with" (with the lifting, with the cutting, with the accumulation, with the deposit); "Four net" (from the net, picking the net , cut net, transport net) to ensure high yields.
