小麦高产是农业技术措施的综合作用,其中土是基础。各地经验表明,要使小麦高产,首先要重视土壤的培肥。为了探讨小麦高产的土壤营养条件,近两年来,我们先后在莱阳、滕县、泰莱平原和邹平县等地,对不同产量麦田的地力水平,作了一些调查分析和田间对比试验,得到了以下粗浅的认识。 High-yielding wheat is a combined effect of agricultural technological measures, of which soil is the foundation. Experience shows that to make wheat high yield, we must first attach importance to soil fertility. In order to investigate the soil nutrient conditions for high-yielding wheat, in the past two years, we conducted some investigation and field comparative experiments on the soil fertility levels in different yield wheat fields in Laiyang, Tengxian, Tailai and Zouping counties, The following superficial understanding.
