Impact of climate on agriculture 202 1
1, monsoon climate: Advantages: it is beneficial to crop growth while it is rainy and hot. Disadvantages: The strength of monsoon easily leads to drought and flood disasters, and the effective measure is to build water conservancy facilities.
(1) Tropical monsoon climate-abundant precipitation, combined with rain and heat, is conducive to the development of planting, mostly rice, with two or three crops a year.
Disadvantages: There are many droughts and floods.
(2) Subtropical monsoon climate-abundant precipitation, rain and heat at the same time, plain development and planting, mostly rice, twice a year; Mountainous hills-develop forestry (mainly subtropical evergreen broad-leaved forest).
Disadvantages: frequent droughts and floods; There is relatively little precipitation in winter and spring, which will be affected by low temperature.
(3) The temperate monsoon climate-the same period of rain and heat, is conducive to the development of planting (wheat, corn), with three crops every two years and one crop every year.
Disadvantages: frequent droughts and floods; Relatively little precipitation, water shortage in winter and spring (especially in North China); The heat is relatively insufficient, and it will be affected by low temperature and cold wave (freezing injury) in winter and spring.
2. temperate continental climate-favorable: sufficient light and heat in summer, large temperature difference between day and night, which is conducive to the accumulation of nutrients for crops. It is suitable for developing irrigated agriculture and planting fruits and cotton in areas with abundant water resources.
Disadvantages: dry climate and scarce precipitation (drought is a typical feature, mostly grassland desert), which is suitable for the development of animal husbandry.
3. Mediterranean climate-favorable: summer is full of light and heat, and the temperature difference between day and night is large, which is conducive to the growth of seasonal crops such as vegetables, fruits and flowers (gardening); Mild and rainy winter is conducive to the overwintering of crops.
Disadvantages: less precipitation in summer, large evaporation, different rainy and hot periods, and insufficient irrigation water sources; One of the effective measures is to vigorously build water conservancy and develop water-saving agriculture, such as building reservoirs, transferring water across river basins and planting drought-tolerant crops.
4, temperate maritime climate-benefits: the annual precipitation is even, and the temperature changes little, which is conducive to the growth of juicy pastures and the development of dairy industry.
Disadvantages: insufficient light and heat is not conducive to grain growth and maturity.
5. Tropical rain forest climate-abundant water and heat, suitable for planting rice and tropical cash crops, and also suitable for developing forestry.
6. Tropical desert climate-advantages: sufficient light and heat, suitable for developing irrigated agriculture in areas with water sources;
Disadvantages: perennial drought. Typical: Israel's water-saving agriculture and drip irrigation technology; B. Cotton cultivation in Egypt, long-staple cotton
5. Tropical grassland climate-suitable for developing animal husbandry; Sufficient light and hot water can reasonably develop planting, but the characteristics of dry and wet seasons are easy to bring drought and flood disasters.
6. Coniferous forest climate in sub-cold zone-adverse effects: the long and cold winter is not conducive to agricultural production and food production.
Unstable.
7. Plateau climate-plateau animal husbandry; Sufficient sunshine, large temperature difference between day and night, such as planting highland barley in the valley of Qinghai-Tibet Plateau.
Disadvantages: insufficient heat.
