浙江杭加湖地区盛产水稻,产量己超纲要,但同某些条件类似的地区相比,潜力还很大。如果将这一地区的产量同用辐射能利用率计算的产量相比较,还可大幅度提高。地下水埋藏过浅,土温低,日温差变化小,土壤长期多盐少气及嫌气性还原环境产生一系列有毒物质或气体,乃是这类地区水稻产量不能大幅度提高的主要原因之一。历史和现状说明了这一点,我们和邻省兄弟单位的试验结果亦证明了这一
The Hangjiao Lake area of Zhejiang Province is rich in rice and the output has exceeded the outline. However, compared with some areas with similar conditions, the potential is still great. The output in this area can also be significantly increased if compared to the output calculated using radiation efficiency. Groundwater buried too shallow, low soil temperature, small changes in temperature, the soil a long time more salt and less gas and anaerobic reduction of the environment to produce a series of toxic substances or gases, but this type of rice yield can not be substantially increased one of the main . This is illustrated by history and the status quo, as evidenced by the results of our experiments with fraternal units in neighboring provinces
