[ Objective] The research aimed to study influences of meteorological factors on high-quality summer millet production in north Henan Province. [ Method] By using summer millet yield and corresponding meteorological data in Anyang of Henan, influence of rainfall on yield of new high-quality summer millet vadety during 2003 -2012 was analyzed. [Result]Rainfall during May -July had the maximum influence on summer millet yield. Correlation regression equation was Y = 0.738 8X + 159.991 ( R = 0.982 04), reaching extremely significant level. [ Conclusion ] The re- search could provide scientific basis for sufficiently using local meteorological condition, breeding high-quality summer millet variety and its high yield. 展开更多

[ Objective] The reseamh aimed to analyze the relationship between vertical distribution of four automatic stations and local precipitation in Taihang Mountain of Linzhou. [ Method] Using mesoscale detection and statistical data of the automatic stations in Henan, the geographical distribution of the precipitation affected by underlying surface in mountainous area of Linzhou was analyzed. [ Result] Surface mesoscale wind field convergence line formed by thermal action of inhomogeneous underlying surface and mountainous terrain and upward movement played the strengthening role to the low-level jet. They affected formation and development of strong convective weather. The geographic distribution of precipitation in mountainous area was highly affected by the terrain, and rainfall, precipitation days and intensity in mountainous area were significantly greater than that in the surrounding hills region. In particular, rainfall on the windward slope significantly increased, and rainfall increased as mountain height within a certain height. [ Conclusion] Hourly ground data analysis at automatic stations had very good forecast indication role in formation, development and dissipation of heavy rain in mountainous areas. 展开更多

[Objective] The research aimed to study influence of meteorological factor in late growth stage of wheat. [Method] Based on precipitation, sunshine and yield per unit of wheat in Anyang City in May of 1979-2008, the positive and negative influences of meteorological condition in late growth stage of wheat (May) on wheat yield in Anyang City were analyzed by using agricultural climatic statistical method. Moreover, the reason and defense measure of green-dry hazard in late growth stage of wheat in the city were studied. [Result] When the sunshine percentage in May > 55%, and rainfall < 45 mm, the wheat yield generally increased. But when it was overcast and rainy, and the sunshine was less, especially monthly rainfall > 80 mm, and monthly sunshine percentage < 55%, the wheat yield generally reduced. The overcast and rainy weather, flood in late growth stage of wheat were easy to cause green-dry yield reduction. The rainless weather even drought weren’t obviously unfavorable for good harvest of wheat. In May, when precipitation was too more, or duration was too long, and the air humidity was too big, the normal water supply and inorganic nutrient transmission were affected. Meanwhile, when the overcast and rainy weather was longer, the sunshine was shorter, and the sunshine intensity weakened in late stage, it wasn’t favorable for accumulation of photosynthetic product, and the normal implementing of grouting process was affected. The measures should be used to prevent and control green-dry yield reduction of wheat, such as discharging water and preventing flood, breeding good seed, scientific planting and reasonable irrigation. [Conclusion] The research provided scientific basis for studying variety improvement, scientific plantation, reasonable irrigation, good quality and high yield of wheat. 展开更多
