1、农业生产的地域性。农业生产是在大自然的约束下进行的,不同类型的地区,有着显然不同的生态环境和与之相适应的生产规律。所谓“种禾无期,因地为时”,就是人们常说的“因地制宜”。而超越一定的地域范围,照抄硬搬外地“经验”,没有不失败的。如江汉平原就有丘陵、平原和水网湖区三种类型的小生态区,水、土、温、光、植被等均有不同程度的差别。所以在编研材料的内容选择上要反映出不同地域的特点。 2、农事活动的季节性。农业生产既是经济再生产,更是自然再生产,要严格按自然规律办事。一年四季有春夏秋冬,“二十四气,七十二候”,表现出强烈的季节性。农事活动与其他生产活动截然不同的是周期长,在一地一年仅有一个生产周期,不能多次重复。因此,古人云:“顺天时,量
1, the geographical area of agricultural production. Agricultural production is carried out under the constraints of nature. Different types of regions have obviously different ecological environments and corresponding production laws. The so-called “species Wo Wo period, because of the time” is that people often say “according to local conditions.” And beyond a certain geographical area, copy hard to move outside the “experience”, there is no failure. For example, there are three types of small ecological zones in the Jianghan Plain such as hills, plains and the water network. There are different degrees of water, soil, temperature, light and vegetation. Therefore, the contents of the research materials selection to reflect the characteristics of different regions. 2, the seasonal nature of agricultural activities. Agricultural production is not only an economic reproduction, but also a natural reproduction. We must strictly follow the laws of nature. Spring, summer, autumn and winter throughout the year, “Twenty-four gas, seventy wait”, showing a strong seasonal. Far from other productive activities, agricultural activities have a long cycle, and there is only one production cycle in a year and can not be repeated many times. Therefore, the ancients said: "Shun Tian, volume
