近年来我省及江南各省试种和推广了一批矮杆早稻良种,增产十分显著,种植矮杆种已成为当前水稻增产的一项重要措施。因此,认识它的特性,并进一步挖掘其增产潜力,已成为农业生产上的一项要求。这里仅根据报章杂志的报导和一些会议的资料,谈谈矮杆种的主要生理特性和如何进一步提高产量的问题。 一、矮杆种的丰产特性 矮杆种为什么能够增产呢?总的来说,是由于其具有优良的株型和旺盛的生理活性。下面仅就这两方面作一些分析。
In recent years, a batch of short-stem early rice varieties have been planted and popularized in various provinces in our province and southern Yangtze River provinces. The yield increase is very significant. Dwarf rod-planting has become an important measure for increasing rice yield. Therefore, recognizing its characteristics and further digging up its yield potential has become a requirement of agricultural production. According to reports from newspapers and magazines and some meetings, the main physiological characteristics of dwarf species and how to further increase their output are discussed here. First, the high yield characteristics of short rod species Short rod species can increase production Why? In general, is due to its excellent plant type and strong physiological activity. Below only some analysis of these two aspects.
