本课题系安徽省科委1981年下达的省重点研究项目,由安徽省农科院作物研究所主持。三年来,经过36个科研、示范,推广部门组成的协作组共同势力,针对当前淮北大面积小麦生产低而不稳的实际,通过宏观调查与微观田间试验相结合的研究方法,取得了六项研究成果。即:研究肯定了“化肥起步,氮磷配合”是淮北大面积中低产地区小麦增产的一条正确途径;土壤基础肥力和化肥对小麦产量的作用;无机氮磷化肥的施用技术及其对小麦产量因素的影响;小麦播期范围及其对小麦形态指标和产量结构的影响;不同类型小麦品种的种植密度与土壤肥力之间的关系;初步组装淮北地区小麦低耗稳产300公斤栽培模式。其中探明中低产小麦栽培的合
The subject of Anhui Provincial Science and Technology Commission in 1981 issued by the provincial key research projects, hosted by the Crop Research Institute of Anhui Academy of Agricultural Sciences. In the past three years, after 36 scientific research, demonstration and promotion departments have formed a common force in the collaboration group, in light of the current low and unstable instability of large-area wheat production in Huaibei, six research projects have been conducted through a combination of macro-investigation and micro- Research results. That is: the study confirmed that “the start of chemical fertilizers, nitrogen and phosphorus with” is a large area of middle and low yielding areas in northern Jiangsu wheat yield a correct way; soil fertility and chemical fertilizers on wheat yield; application of inorganic nitrogen and phosphorus fertilizer and its impact on wheat yield The influence of factors; the sowing date of wheat and its effect on wheat morphological index and yield structure; the relationship between planting density and soil fertility of different types of wheat varieties; preliminarily assembling 300 kg of wheat with low energy consumption and stable yield in Huaibei area. Among them, proven low-yielding wheat cultivation
