豫西丘陵旱作生态类型麦区,常年小麦播种面积650万亩左右,占全区总耕地面积的56.8%。多年来,小麦产量低而不稳,单产一般在75—160公斤_2普遍认为“旱、薄、粗”是限制本区小麦生产的主要因素。农业科技人员从各个方面进行了研究,并已肯定了增施肥料,适时播种、合理密植等是具有一定增产作用的农艺措施。但这些研究大都限于一定生态条件下的单项实验和生产经验总结,缺乏综合农艺措施组装配套的定量研
Hilly west of dry farming ecological type of wheat area, perennial wheat sown area of 6.5 million mu, accounting for 56.8% of the total area of cultivated land. Over the years, wheat production has been low and unstable, with yields generally ranging from 75 to 160 kg. 2 It is generally accepted that “drought, thin and coarse” are the major factors limiting the wheat production in this area. Agricultural science and technology personnel from all aspects of research, and has affirmed the increase of fertilizers, timely sowing, reasonable and close planting is a must increase agricultural production measures. However, most of these researches are limited to the conclusion of individual experiment and production experience under certain ecological conditions, and the lack of quantitative analysis of the comprehensive agronomic measures assembly
