小麦是本地区的主要粮食作物之一。单产低而不稳是本区小麦生产的主要特点,造成这种特点的原因是多方面的,气候条件的影响是其主要原因之一。从产量结构看,“低而不稳”的主要原因是有效穗数的不稳定。因此,研究本区小麦茎蘖的增长规律,以及气象条件对茎蘖增长的影响,在生产上必然具有一定价值。关于小麦分蘖规律以及环境因子对小麦分蘖的影响,国内外许多学者曾作过深入研究。日本的片山佃最先指出了小麦的“同伸分蘖”、“同伸叶片”规律:1975年邓根云
Wheat is one of the main food crops in the region. Low yields and instability are the main features of wheat production in this area. The reasons for this are many. The impact of climatic conditions is one of the main reasons for this. From the output structure, the main reason for “low and unstable” is the instability of the effective spikes. Therefore, it is necessary to study the growth rule of wheat tiller and the influence of meteorological conditions on the growth of stem tiller, which is bound to have some value in production. With regard to the tillering rule of wheat and the effect of environmental factors on tillering of wheat, many scholars at home and abroad have conducted in-depth studies. Japan’s Leshan Dian first pointed out that the wheat “with the extension of tillering”, “with the extension of leaves” rule: Deng Gengyun in 1975
