Sweet potato is a vegetative breeding vegetative body, there is no obvious standard of maturity and harvest period, but harvesting too early will reduce the yield of sweet potato; late harvest, sweet potato will be affected by low temperature chilling, intolerant storage, cut rate will decline. Therefore, when harvesting sweet potatoes, it is necessary to pay attention to four points: “landâ€, “earthâ€, “stayâ€, and “useâ€.
1. "Ground" harvests sweet potatoes based on the ground temperature. Generally, harvesting of sweet potatoes begins at ground temperature of 18°C, and plots of spring potatoes used for cutting or winter wheat for harvesting are generally harvested before cold dew; the spent summer potatoes are harvested before the frost falls; sweet potatoes stored for later consumption may be later Some cropping, but it must be finished before the frost.
2. "Soil" harvests sweet potatoes based on soil moisture. Soil moisture content is small, ground temperature changes, sweet potatoes are vulnerable to cold damage, and not easy to planer; soil moisture is too much, sweet potatoes are not resistant to storage after harvest. When the soil is too wet, the sweet potato vines should be cut off and dried for a few days until the soil is slightly dry and then planed.
3. "Leave" means harvesting sweet potatoes based on whether or not they are left. For the preserved summer potatoes, it is advisable to harvest in the sunny morning and sunbathe in the field. In the afternoon, enter the pit and do not stay overnight in the ground to avoid cold damage.
4. "Use" means to store sweet potatoes according to their use. After the sweet potatoes are harvested, they can be selected in the ground to remove diseased, remnant and water-logged potato pieces, and stored separately according to different uses and varieties. From harvesting to storage, it is advisable to reduce the number of overturns as much as possible, and to take it lightly, gently, lightly, and lightly to avoid bumping the potatoes.
1.The layout of the functional modules of the equipment is reasonable, the structure is compact, and the appearance is beautiful;
2.Feeding and conveying, pressing, cutting, and discharging are completed in one line, which improves cutting quality and production efficiency, greatly reduces labor costs, and improves working conditions;
3.
The feeding conveyor belt adopts high-quality materials and a reasonable surface anti-skid structure, which is wear-resistant, non-slip, and reliable in positioning; the feeding belt component is a quick-install structure to ensure that the belt is replaced and cleaned quickly and conveniently;
