苏联的乌兹别克斯坦在灌溉和非灌溉地区都栽培冬小麦.由于未考虑生态条件对不同品种产量的影响,所以在推广品种时往往带有很大的片面性.因此我们研究了某些冬小麦品种的生物学特性,水-热状况和产量的关系.调查是在抽穗期和籽粒灌浆期,于炎热的有阳光的白天,下午2-3时进行的,当时的气温为37-39℃,相对湿度14-18%.用农业物理研究所的扭秤和微电温度计测定了植株的
Uzbekistan in the Soviet Union cultivated winter wheat in both irrigated and non-irrigated areas, and because it did not consider the impact of ecological conditions on yields of different cultivars, there was often a great one-sidedness in popularizing cultivars. Therefore, we studied the biology of some winter wheat cultivars Characteristics, water-heat status and yield of the relationship between the survey is in the heading and grain filling period, in the hot sunny day, 2-3 o’clock in the afternoon, when the temperature is 37-39 ℃, relative humidity 14- 18%. The plants were determined using a Tensile Scale and a Micro-Thermometer of the Institute of Agricultural Physics
