What are the main aspects of the influence of Meiyu weather process on agricultural production?

The influence of Meiyu weather process on agricultural production is mainly reflected in the following aspects:

1, crop growth is hindered: continuous rainfall in rainy season will lead to water accumulation in farmland and excessive soil moisture, which will affect the growth and absorption capacity of crop roots, thus hindering crop growth and reducing yield.

2. Breeding of pests and diseases: The high humidity and high temperature in rainy season are conducive to the breeding and spread of pests and diseases, which increases the difficulty and cost of agricultural control.

3. Quality decline: Rainwater in rainy season will make agricultural products easy to rot and deteriorate, which not only affects the quality of agricultural products, but also may lead to economic losses.

4. Poor drainage of farmland: Continuous rainfall in rainy season will lead to poor drainage of farmland and excessive soil moisture, which will affect photosynthesis and respiration of crops, and then affect yield and quality.

5. Increased risk of meteorological disasters: The rainy season may also cause meteorological disasters such as floods, lightning and strong winds, which will adversely affect agricultural production.

Influence of Meiyu weather process on agricultural production and its countermeasures;

1, irrigation and water conservancy construction is an important means to reduce the impact of rainy weather on agricultural production. By strengthening farmland water conservancy construction and improving drainage capacity, farmland water accumulation can be effectively reduced and the influence of excessive soil moisture on crop growth can be avoided. For example, we can build drainage ditches and improve the drainage system to ensure that rainwater can be discharged from farmland in time.

2. Selecting crop varieties with strong waterlogging resistance, disease resistance and stress resistance is another important measure to reduce the impact of rainy weather on agricultural production. Waterlogging-tolerant crop varieties can grow normally in rainy environment, while crop varieties with strong disease resistance and stress resistance can reduce the occurrence and spread of pests and diseases, and reduce the difficulty and cost of control. This goal can be achieved by introducing excellent varieties and cultivating varieties suitable for local growth.

3. Scientific arrangement of farming activities is one of the key measures to reduce the influence of rainy weather on agricultural production. In the rainy season, centralized sowing and harvesting should be avoided as much as possible to reduce the impact of agricultural activities on crop growth and harvesting. For example, sowing and harvesting time can be arranged reasonably according to local climate characteristics and crop growth cycle, and the peak season of rainy season can be staggered.
