Sugar beet mid-term water and fertilizer management technology

At present, the growth of sugar beet has entered the rapid growth period of leaf plexus. At this time, the growth rate of sugar beet leaves is the fastest, and the tissue differentiation speed of roots is also the fastest. During this period, crops need a sharp increase in nutrition, which is the best time for watering and topdressing.
1. Topdressing method:
(1) Mechanical deep application: It is recommended to use the “Beet Cultivated Fertilizer Machine” provided by Baotou Huazi Industrial Co., Ltd. This machine is powered by a small four-wheel tractor with 18-horsepower hydraulic equipment. In one operation, four rows of sugar beet, loose grass, cultivating, deep application of top dressing, and soil cultivation can be completed. The effect is very good, and it is used in a large area of ​​our alliance.
(2) Deep application of animal power: In the absence of special machinery, it is also possible to carry out deep application of topdressing with the “legs of both legs” pulled by the animal force.
(3) Artificial deep application: “planting fertilizer” around the beet with an on-demand device.
2, topdressing requirements:
(1) Depth of fertilization: too deep fertilization affects fertilizer efficiency, and too shallow is volatile, suitable for depth of 6-15CM.
(2) Deep application position: When applying topdressing, the lateral distance between fertilizer and sugar beet plants should be kept at 10-12CM.
3. Fertilizer and dosage:
(1) Beet topdressing is carried out by the sweet special topdressing that is captured by Baotou Huazi Industrial Company. This fertilizer is a special type of fertilizer that is processed and manufactured according to the characteristics of soil nutrient status, nutrient supply capacity, sugar beet growth and development, and fertilizer requirement. The total amount of nitrogen, phosphorus and potassium nutrients in the fertilizer is 32%, and the total amount of elements such as sulfur, calcium, magnesium, zinc, boron and iron is 15%, and the humic acid content is 10%. This fertilizer contains a complete range of nutrients, a variety of nutrient content and appropriate ratio, can play a role in balanced fertilization of sugar beet. After application, the sugar beet can meet the needs of various nutrients, coordinate the supply of nutrients, prevent the occurrence of nutritional disorders, and benefit the growth and development of sugar beets and promote the quality of sugar beets.
(2) Dosage: 50KG for beet special fertilizer application per mu
