花生是河南主要经济作物之一,多分布在沙地或山区,由于土壤肥力差,水利设施不足,历年产量受气象因素影响变幅极大,但哪些气象因子是影响产量变异的主要因素?在生育期的各阶段其作用如何?过去很少进行研究.本文以予东北沙区为例,以解放以来能收集到的资料为基础,对这些问题进行初步探讨.材料和方法本文收集了中牟县23年,濮阳县28年,民权县26年共77年次的资料,各地的花生产量均存在明显的时间趋势,即由于三十年来品种的更新、技术的提高以及其它因素的影
Peanut, one of the major cash crops in Henan, is mainly distributed in sandy or mountainous areas. Due to poor soil fertility and inadequate water conservancy facilities, peanut yield fluctuates greatly in the past years under the influence of meteorological factors. However, which meteorological factors are the main factors affecting yield variation? The role of the various stages of the growth period? In the past rarely studied.In this paper, taking the northeast sand area as an example, based on the information that can be collected since the liberation, the preliminary discussion of these issues.Materials and MethodsIn this paper, Zhongmou County 23 years, Puyang County 28 years, Civil Rights County 26 years a total of 77 years of information, all over the peanut production there is a clear trend of time, that is, due to three decades of species updates, technology improvements and other factors
