摘要
从农业气候生态角度分析了影响豫南稻区小麦产量及其构成因素的气候因子,结果表明,对豫南稻区小麦生产影响最大的气候因子是涝灾。由于降水冬前比冬后变化大,常出现生育前期旱涝和中后期湿害。因此,建议在选用小麦品种时,一要注重早熟性,二要注意产量三要素协调、丰产性好,三要有配套的耕作栽培技术。
The paper focuses on the ecological agricuhural perspective, analyzing the climatic factors which impact on wheat production and component factors in the south of Henan province. The flood is the most prominent climatic factor. Because the precipitation change before winter is bigger than after winter, there often appear drought and flood in early growing period, and wet damage in mid - late growing period. When we select the wheat varieties, first of a11, should pay attention to the precocious characteristic, and then the coordination of production three elements and prolificacy, third, the farming cuhivation techniques.
