What are the favorable and unfavorable effects of Shaoxing's climate characteristics on crop growth? What measures do you think can be taken to deal with it?

Unfavorable climate has an impact on agricultural production in spring. According to the statistics of the municipal meteorological department, from February last year to March this year, the rainfall was 467 mm, 192 mm more than the same period last year, with an increase of 70%. However, in June this year, the average temperature in 5438+ 10 was 1.2℃ lower than normal, the average temperature in February was 0.7℃ lower than normal, and the weather in March was abnormal, which adversely affected the growth of crops in spring. According to the survey, wheat and wheat seedlings are weak and the number of seedlings is insufficient; Rape has many old leaves and yellow leaves, which causes serious freezing damage and delayed bolting; Green manure seedlings have few branches and some green manure fields are seriously waterlogged. Among the spring flower crops in the city, the first-class seedlings account for about 30%, the second-class seedlings account for 45%, and the third-class seedlings account for 25%. The impact of cash crops such as tea is more serious. According to statistics, the frozen area of clonal tea gardens in the city is 56,000 mu, resulting in a direct loss of more than 78 million yuan. Shaoxing City is located in the transitional zone of subtropical monsoon climate in north-central China, with distinct four seasons, mild climate, excellent light and heat, rainy and humid, and suitable for multiple cropping production. The landform types are diverse, and the local microclimate resources are rich, which is conducive to biological reproduction. However, disastrous weather such as floods, droughts and low temperatures often occur, which affects high and stable agricultural production, and even causes large-scale crop production reduction and major economic losses in serious cases. Therefore, it is of great significance to improve the understanding of agricultural disastrous climate, strengthen the defense and response to agricultural disastrous climate, foster strengths and avoid weaknesses in agricultural production layout, adjust measures to local conditions, and rationally utilize climate resources for promoting stable and high-yield agriculture and sustained and healthy development of rural economy.
