Choose land with deep soil, good drainage and aeration, crop rotation for more than 4 years, no repeated cropping, no stubble, and medium or above fertility. It is required to turn over in autumn

more than 25 cm, water well in autumn, and apply 5,000 kilograms of high-quality organic fertilizer in autumn or spring. Before sowing, rake deeply with a notched rake, then rake twice vertically and horizontally with an iron rake, and then suppress it once. The quality of land preparation must meet the requirements of flat soil, loose soil at the top, solid soil at the bottom, no lumps, no roots and stubble, and good and even moisture. Combined with land preparation, apply 20-25 kg of diammonium phosphate per acre deep, and no seed fertilizer will be applied during sowing.

2. Variety Selection

ff10000, No. 5 for internal feeding.

3. Sowing and seed treatment

If the seeds are coated, no treatment is required. If the seeds are not coated, 0.1 kg of 40 methyl isothionate and 15 kg of water plus 80 Mix 70 grams of diclosan wettable powder into a liquid solution to soak 10 kilograms of seeds, and sow seeds for 24 hours. There are 3,300-3,500 seedlings per acre, with row spacing of 50 cm and plant-to-plant spacing of 37-40 cm. About 0.35 kg of seeds are used per acre, and 3-4 seeds are sown in each hole.

Sowing method: The price of imported seeds is relatively high. In order to reduce production costs and ensure the emergence rate, artificial on-demand sowing and plastic film covering can be adopted. For open field live broadcasting, rows can be rowed at an equal distance of 50 cm, and trenches can be dug. Manual broadcasting can be rowed at an equal distance of 37-40 cm. For mulching, the rows can be rowed at an equal distance of 1 meter. Each row should be covered with 90 cm mulching film. Each row should be planted with two rows, and the row spacing 50 cm, plant spacing 37-40 cm. The sowing depth depends on the soil moisture. It must be 2-3 cm. Sugar beets covered with mulch film can be sown shallowly. The sowing time is April 5-15.

4. Field Management

When the sugar beet grows 1-2 pairs of true leaves, the seedlings should be planted and thinned in time, and at the same time, it should be combined with thinning of vegetable seedlings and cultivating and weeding. If there is a lack of seedlings, the seedlings can be transplanted on the spot. Transplanting the seedlings at this time not only has a high survival rate, but also does not affect the growth of the main root. When the sugar beet grows 3-4 pairs of true leaves, the seedlings should be planted in time. When the seedlings are planted, they should be cultivated and weeded in time. The roots of fodder beet are thick, with 1/3 underground and 2/3 above the ground. The roots are barrel-shaped. In order to prevent lodging, soil cultivation of the roots should be strengthened in the mid-term.

5. Watering and fertilization

When watering in the middle of June, apply 25 kilograms of urea per acre in combination with watering. Watering in early July, and then the two waterings in mid-August. and watering in early September. When watering, you should pay attention to: first, it is best not to water in mid-to-late July, and second, do not water after heavy rain to prevent the beet roots from rotting.

6. Pest Control

During the seedling stage, pests such as sweet weevils and cutworms should be checked in time. If they occur, they can be sprayed with 2000-2500 times of the insecticide. During the period when stems and leaves are flourishing, attention should be paid to preventing and controlling cabbage exigua moth. The main control chemicals are enemy killing, killing and killing, etc.

7. Harvest and Storage

Feeding sweet can delay the harvest period appropriately. The specific time can be determined according to the local autumn watering time, generally around October 10th. After harvesting, if conditions permit, the silage can be crushed into pieces and mixed with corn straw, or can be siled separately. It can also be stacked on the sunny side of the house for winter storage, or it can be covered with soil and buried deeply, but it should be noted that the thickness of the covering soil is about 83 centimeters. , it is necessary to prevent both freezing and heat. Ensure feeding quality throughout winter and spring. (Anonymous)
