Beet harvest management skills
First, field management
1. Fertilizer control. The late stage of sugar beet growth is the key period for the accumulation of root sugar. It is necessary to severely stop the application of nitrogen fertilizers, prevent the growth of legacies, promote the transport of organics from the shoots to the roots of the roots, and co-operate the spraying of high-efficiency sugar enhancers 1 or 2 times to increase the sugar content and processing quality of the roots. To control the sprinkling, stop the watering 20 days before the harvest to prevent excessive moisture formation and decay.
2. Prevention and control of pests and diseases. Points to prevent and control beet brown spot, powdery mildew, leafhoppers and so on. In this period, mechanical weeding cannot be performed. Large grasses can be removed manually on heavier plots to reduce weed damage.
3. Prevent sugar beet leaf damage. The number of functional sugar beet leaves is directly related to the root output value and sugar content, and it is forbidden to artificially cut the functional leaves at the later stage, and to maintain the number of life extension blades as much as possible to prevent a significant reduction in production.
4. Finish the drip irrigation tube. For drip-irrigated sugar beets, the drip irrigation supervisor and the capillary tube shall be promptly recovered before the harvest to prepare for the mechanized harvest.
Second, harvest management
1. timely harvest. From the end of September to the end of October, it is necessary to gather human and material resources in time to prevent damage due to early frost formation, or the formation of roots due to freezing on the surface is difficult to obtain.
2. Mechanical harvest. Large-area cultivation can be carried out by using a large-scale sugar beet harvester for joint harvesting, or using a sugar beet slicing machine to cut sorghum first, and then using an excavation container collection machine for harvesting. In small-scale divergence cultivation, first the leaf is used to break up the leaves, the green head is cut off, and then the sugar beet excavation machine is used to start harvesting. When there is no receiver, mechanical loosening can be used, manual picking and cutting can be used, or cutting machine can be used for cutting, mechanical loosening and manual picking up.
3. Disease root treatment. For beetroot rot and rhizome attack plots, collect and infiltrate decayed and low-rooted roots in the harvest process to reduce the number of bacteria sources and reduce the loss of materials during the storage of sugar beets and during processing. The loss of the process.
4. Stacking sales. After the harvest of the sugar beet, it must be sold in a timely manner. If it cannot be sold in time, it should be piled up, pay attention to the preservation, and reduce the loss.
5. Recover the remaining film. Film-covered sugar beet, after the harvest, the residual film on the surface should be promptly eradicated to prevent soil pollution and affect the growth of the crop after the harvest.
