1光照、温度、水对小麦生产的影响1.1光照小麦适应性强,分布范围广,云南省海拔300~3000m的地区均有分布,但主产区一般在1 000~2 500m的范围内。我州主要在1 000~1 700m范围内分布有,且多以栽种冬小麦为主。我州冬春干旱少雨,光照相对充足,有利于小麦进行光合作用,小麦干物质中,有90%~95%是光合作用制造的有机物质,光能条件与作物产量有着直接的关系,我州日照时数的季节分布在2~6月份,小麦属于长日照作物,除前期需要较低的温度条件外,还需要较长的日照时间才能通过生长发育,正常
1 Effects of Light, Temperature and Water on Wheat 1.1 Light Irrigation Wheat has strong adaptability and wide distribution range. There are distributions in 300 ~ 3000m above sea level in Yunnan Province, but the main producing areas are generally in the range of 1 000 ~ 2 500 m. My state is mainly distributed in the range of 1 000 ~ 1 700m, and mostly planted winter wheat. In winter and spring of our country, arid and rainy days, the light is relatively abundant, which is good for photosynthesis of wheat. 90% -95% of wheat dry matter is organic matter produced by photosynthesis. Light energy has a direct relationship with crop yield. The season of sunshine duration is from June to June. Wheat is a long-day crop, which requires a longer sunshine duration to pass growth and development and normal
