一前言小麦在丰产栽培条件下能以达到高额而稳定的产量,这是综合运用农业八字宪法的结果,但八字宪法中各个措施怎样运用才为合理?又各个措施的增产作用以及各个措施如何配合才能发挥其增产的最大作用?这是爭取达到更高产量水平中应該研究的问题。因此,我们特在小麦丰产田內采用了不同前茬、不同密度和不同品种的丰产比較試驗。除肥、水措施完全相同外,专研究小麦高产的培养地力,合理密植和丰产品种等问题。經过一年来 Foreword Wheat can achieve high and stable output under high-yield cultivation conditions, which is the result of the comprehensive application of the eight-character constitution of agriculture. However, how can the various measures in the eight-character constitution be used rationally? What are the measures for increasing production and how are the measures taken? Cooperation can play its biggest role in increasing production? This is to strive for higher output levels should be studied. Therefore, we use special wheat in different fields with different yield, density and different varieties of high yield comparison test. In addition to fertilizer, water exactly the same measure, the special wheat cultivation of high yielding land, close planting and high yield varieties and other issues. After a year
