The time to harvest peanuts varies depending on the region and climate, but it is usually in the fall. In temperate regions of the Northern Hemisphere, peanuts typically mature between late summer and early fall, depending on the variety grown and local weather conditions. In the Southern Hemisphere, peanuts are harvested in the spring.
Generally, when the leaves of a peanut start to turn yellow and wither, it means that the peanut is ripe and ready to be harvested. By this time, the stems and roots of the peanuts have stopped growing, most of the pods are full, and the oil content has reached its highest point. If the harvest time is too early, the peanut is not fully ripe, which will affect the yield and quality; If harvested too late, it is prone to fruit drop and germination, which will also affect yield and quality.
Therefore, it is very important to harvest peanuts at the right time. Before harvesting, it is best to know the local climate and soil conditions, as well as the varieties planted and growth, so that the best time to harvest can be determined. In addition, it is also necessary to pay attention to the weather forecast and avoid harvesting in rainy days, which may affect the quality and storage of peanuts.
When harvesting peanuts, you can harvest them mechanically or by hand. Mechanical harvesting is suitable for large-scale peanut fields and can greatly improve harvesting efficiency. Manual harvesting is suitable for peanut fields planted in small areas or plots that are inaccessible by machinery, and although it is less efficient, it can guarantee the quality of the harvest.
After harvesting, the peanuts need to be dried, stored, and processed. Drying can remove excess moisture from peanuts and prevent mold and spoilage. When storing, care should be taken to keep it dry and ventilated to avoid moisture and insect infestation. The processing method can be selected according to the market demand, such as roasted peanuts, boiled peanuts, peanut oil, etc.
In conclusion, harvesting peanuts at the right time and correctly is the key to ensuring yield and quality. Understanding the local planting conditions and market demand, choosing the right harvesting method, paying attention to the weather forecast and storage and processing methods are important measures to improve the yield and quality of peanuts.
In addition to timely harvesting, there are a number of other management measures that can help improve the yield and quality of peanuts. For example, reasonable dense planting can improve photosynthesis efficiency and yield; Scientific fertilization can provide sufficient nutrients to promote the growth and development of peanuts; Pest control can reduce peanut losses and improve quality and yield.
In addition, the selection of excellent varieties is also an important way to improve the yield and quality of peanuts. Excellent varieties have the advantages of vigorous growth, strong resistance to stress and wide adaptation, which can greatly improve the yield and quality of peanuts. Therefore, before planting, it is necessary to understand the market demand and local planting conditions, and choose suitable varieties for planting.
In conclusion, harvesting peanuts requires attention to the right time, the right way and good management practices. Only by mastering these key technologies can we ensure the yield and quality of peanuts and improve economic and social benefits. At the same time, it is also necessary to pay attention to the protection of the ecological environment and the sustainable use of resources to achieve sustainable development of agriculture.
