What crops are suitable for growing in the fields in winter?
Due to the onset of winter and the colder and cooler temperatures, many crops will grow slowly or even enter hibernation. However, there are also some crops that grow well in the harsh winters, giving farmers a good harvest. What crops grow in the fields in winter? The article mainly recommends several crops suitable for winter cultivation, and conducts a review of their cultivation techniques. 1. Crops suitable for winter cultivation 1Winter wheat is an important food crop in North China, and it is also the most representative winter cultivar. After a cold winter through autumn sowing, the wheat will be in hibernation, and the following spring, when the temperature warms, it will re-germinate and be harvested in the summer. When sowing seeds in winter, it is necessary to ensure that there is a high resistance to cold and that the moisture of the soil is not affected.
2.Vegetables are a staple crop in winter farmland, especially vegetables with green leaves such as spinach and canola. Due to its fast growth period, it has high nutrition and large market demand. In the cultivation process, it is necessary to do a good job in field management, so as to achieve soil and water conservation, weed removal, and prevention of diseases and pests. 3.In the winter fields, beans, broad beans, etc. are also good foods. Soybeans are rich in protein and high in nutrients, and they are also resistant to cold. In cultivation, it is necessary to achieve high density and ensure the fertility of the land. 4.Wheat is a wheat crop, including barley and wheat with high cold resistance and adaptability. Therefore, in production practice, we should pay attention to timely, timely, timely and effective field management to achieve the purpose of high yield and high quality. Second, the main points of winter and spring crop cultivation 1Screening suitable cultivars for overwintering is an important part of spring sowing. Due to the differences in climate and soil properties in different regions, crops suitable for local cultivation should be selected. In this process, seeds should be sown in time to prevent frost damage and growth and development disorders caused by early or late sowing.
2.In winter, crops grow slowly and require less nutrients. However, in order to achieve the goal of high yield and high quality, it is also necessary to apply fertilizer appropriately. Therefore, before planting, organic fertilizer should be adequately applied, supplemented with appropriate fertilizer. Throughout the growth process, it depends on the growth of the crop. 3.In winter, it is necessary to ensure a certain amount of humidity due to the decrease in temperature, but in winter, the evaporation of water is relatively slow due to the decrease in temperature. Appropriate irrigation should be carried out according to the growth and development of crops and water conditions to prevent soil hardening and frost damage caused by excessive irrigation. It is necessary to do a good job of draining the fields to prevent water accumulation in the fields and causing crops to be flooded. 4.The prevention and control of pests and diseases is one of the main ways to increase grain yield and improve quality. It is necessary to pay close attention to the growth of crops and detect and control pests as early as possible. Comprehensive management measures can be adopted by taking measures such as biological control and chemical control. When applying pesticides, green pesticides with low toxicity and low residue should be selected to avoid harm to ecology and human health.
In general, there are many crops that can be grown in the field in winter, but it is necessary to choose the right crops according to the weather conditions and the nature of the land in the area. In cultivation, attention should be paid to seed selection, sowing, fertilization, watering, drainage and prevention of pests and diseases, so as to achieve the purpose of high yield and high quality. On this basis, we should follow the principle of "green environmental protection" and scientifically apply chemical fertilizers and pesticides to protect human health.
