气侯与种植制度 太湖地区雨量充沛,温度适宜,属于北亚热带气候区,≥10℃的积温为5000—5326℃·日,北部为5000℃·日,南部为5200℃·日以上,同纬度的东部积温小于西部积温。本区种植制度复杂,气候适宜多种作物生长,有利于农业生产综合发展。 种植制度与气候的关系密切,相互影响。种植制度气候适应性,侧重于各种熟制的气候适应性。例如,麦玉米稻,除丹阳、溧阳只能部分种植外,其他各县均宜种植,麦豆稻除吴县、吴江适宜种植外,其他各地只宜部分种植;早三熟[早熟三号大麦+早双季(中熟早籼原丰早+中粳)),除吴江、吴县适宜种植外,其他地方只能部分种植;晚三熟(大元麦+晚熟早籼广四+早熟晚粳武农早),除丹阳不宜种植和吴江偏南一带适宜种植外,其余地区只能部分种植;早双季[中熟早籼(原丰早)+中粳(南粳33)组成]、中双季[迟熟早籼(广四)+中粳]除苏州以南一线适宜种植外,其他均属部分种植,晚双季[迟熟早籼(广四)+杂交稻]除江阴、沙州、金坛、太仓一线不宜种植外,其他地区只能部分种植;麦(油)稻二熟制,小麦+迟熟晚粳C油稻[晚粳)],只能在吴江偏南地区适种,其余部分种植。麦稻(早熟晚粳,
Climate and Planting System The rainfall in the Taihu Lake region is abundant and the temperature is suitable. It belongs to the northern subtropical climatic zone. The accumulated temperature of ≥10 ℃ is 5000-5326 ℃ · day, the northern part is 5000 ℃ · day, the southern part is 5200 ℃ · day, the same latitude The eastern accumulated temperature is less than the western accumulated temperature. The planting system in this area is complex and the climate is suitable for the growth of a variety of crops, which is conducive to the comprehensive development of agricultural production. Planting system and climate are closely related and influence each other. Planting system Climate adaptation, focusing on a variety of cooked climatic adaptability. For example, wheat and maize except Danyang and Liyang can only be partially planted, and should be planted in other counties. The wheat and pea varieties should only be partially planted in addition to Wuxian and Wujiang; Early Shuangjiu (middle maturing early indica Happo morning + middle japonica)), except for Wujiang and Wuxian suitable for planting, other places can only be partially planted; late-maturing (Dayuanmai + late maturing early indica Guangsi + early maturing late japonica rice (Early Fengzao) + middle japonica (southern japonica 33) composition), in the double Seasonal [late indica indica (Guangsi) + medium japonica] except south of Suzhou suitable for planting, the other are part of the planting, late double season [early maturing indica (G) + hybrid rice] in addition to Jiangyin, Shazhou , Jintan, Taicang first line should not be planted, and other areas can only be partially planted; wheat (oil) rice two cooked, wheat + late late C japonica rice [late japonica]), only in the southern part of Wujiang suitable , The rest planted. Malting rice (early maturing late japonica,
