The impact of cold and dry weather in Shijiazhuang on crops in spring

1. The impact of cold and dry weather in Shijiazhuang on crops in spring:

1. The impact of cold and low temperature on crops

Low temperature damage affects the stable and sustainable development of agricultural production. One of the important disasters, the harm to different crops, varieties and development stages is different. Crop varieties are not resistant to low temperatures, and fruit trees and vegetables are prone to frostbite below 0°C. Crops generally have strong defenses against cold damage during the seedling stage and late growth period, and are more sensitive to cold damage during heading, flowering, and early stages of grain filling. Over a long period of time, cold damage will delay the development period of crops, resulting in reduced crop yields. It will also damage the reproductive organs of crops, leaving more empty shells and reducing yields. Cold damage has a great impact on crops such as wheat, rice, fruit trees, and vegetables.

2. The impact of dryness and lack of rainfall on crops

The climate is dry, highlighted by less precipitation. Dryness and lack of rain have a greater impact on crops, which cannot meet the crop's demand for water during a specific growth period. The water absorbed by the crop root system from the soil cannot compensate for the water consumed by transpiration, causing the water balance in the plant to become imbalanced. It seriously affects the normal growth and even death of crops. Widespread dryness and lack of rainfall will significantly reduce crop yields, and in severe cases may even result in no harvest.

2. However, Shijiazhuang is close to the Bohai Sea of ??the Pacific Ocean and has a temperate continental monsoon climate. The weather in spring and autumn is relatively mild. Although there is less precipitation in spring, it is not cold and dry in most cases. Cold and dry weather mainly occurs in winter, with frequent northeasterly winds. Hot and dry weather mainly occurs in summer, with strong southeasterly winds.

3. Response measures

1. Develop biotechnology, select and breed new crop varieties suitable for climate change, and rationally adjust the agricultural structure and planting system. In order to achieve major breakthroughs and progress, breeding excellent varieties requires strengthening technological development and research in biotechnology, photosynthesis, and stress resistance to improve people's ability to adapt to climate change and its impact on agriculture.

2. Improve agricultural infrastructure. In order to improve the level of disaster resistance and reduction and agricultural resilience, it is necessary to strengthen the construction of agricultural infrastructure. In order to strengthen the research, promotion and application of water-saving agriculture and scientific irrigation agriculture, it is necessary to develop new agricultural production processes to adapt to climate changes.
