湖北中部及长江两岸在解放以来历年小麦收成差别很大。如1953年春季雨量分布播适宜,普遍丰收;1954年秋旱迟播,遭遇冻害,且在小麦生长发育后期雨水过多,黑锈病严重而导至减产。气候条件是影响小麦生长发育阶段,生物学特性和产量的重要因素。因此,我们从1956年冬播起进行了小麦分期播种试验,研究小麦生长发育和产量与气候因子的关系,从而探求小麦生长发育阶段以及获得稳定而高额产量所要求的气候条件,并确定最适宜的播种期和播种期限度。
The harvests of wheat in the central and northern regions of Hubei Province since the liberation have varied greatly in recent years. For example, the distribution of rainfall in spring 1953 was suitable and generally bumper; in the autumn of 1954, it was late sowed in autumn and suffered frost damage. In the latter part of the growth and development of wheat, there was too much rain and serious black rust led to decrease in yield. Climatic conditions are important factors affecting wheat growth and development stage, biological characteristics and yield. Therefore, we conducted a wheat sowing experiment from the winter of 1956 to study the relationship between wheat growth and yield and climatic factors so as to explore the climatic conditions required for stable and high-yield wheat growth and development and to determine the most suitable Suitable sowing and sowing time limits.
