种植制度的研究和改革,是农业战线一项有关全局战略性的决策。一个地方熟制的形成是有着多种原因。地处长江流域下游的浙江北部,对现行种植制度,多年来有着不同看法,特别在1980、1981年晚稻遭受到冷害影响,对熟制更有分岐。主要归纳有三点:首先对热量资源,有“三季不足,二季有余”和“季节稍紧,基本满足”之争。其次,从产量考虑,有“三三得九,不如二五得十”或“三四十二,超过二五得十”之议。第三,从成本出发,是“抓粮”还是“抓钱”。因此,对种植制度以三熟还是以二熟为主形成不同看法。本文根据浙北嘉兴市属,湖州市属八个县,四个区(县级)对现行熟制和气候资源作一初步探讨。
The study and reform of the planting system is a strategic decision on the agriculture front regarding the overall situation. There are many reasons for the formation of a local cooked. Located in the lower reaches of the Yangtze River valley in northern Zhejiang, the current cropping system has different views over the years, especially in 1980, 1981, suffered cold damage late rice, cooked more divergent. There are three main points: First of all, the heat resources, there are “less than three quarters, more than two seasons,” and “slightly tighter seasons, basic satisfaction,” the dispute. Second, from the yield considerations, there are “three or three nine, not as good as twenty-five ten” or “three forty-two, more than twenty-five ten” proposal. Third, starting from the cost, is “grasping grain” or “grasping money.” Therefore, the cultivation system to three or second crop to form a different perspective. According to the genus Jiaxing City in northern Zhejiang, Huzhou belongs to eight counties, four districts (county level) on the current cooked and climate resources to make a preliminary study.
