不论小麦或大麦、蚕豆、豌豆和油菜在华南冬播(立冬前后)春收(清明前后),其产量都低而不稳。究其原因主要是华南的气候条件与上述作物对环境条件要求不相适应,不适应的时段则主要是当地二三月。此间,光、温、降雨、大气湿度等条件不良。为此我们的研究工作以全盘调整种植制度为前提,以合理而充分利用当地的资源(包括气候、劳力、土地等)达到三熟高产稳产、合理用田养田为目的,对本地的三熟制进行了新的探索,并取得了预期的结果。
Whether wheat or barley, broad bean, pea and rape in the South China winter sowing (before and after winter) spring income (around the Qingming), its production is low and unstable. The main reason is that the climatic conditions in South China are incompatible with the requirements of the above-mentioned crops for environmental conditions, and the time periods that are not suitable are mainly the local months and March. Here, light, temperature, rainfall, atmospheric humidity and other poor conditions. To this end, our research work is based on the premise of overall adjustment of cropping system. In order to rationally and make full use of local resources (including climate, labor and land, etc.) Made a new exploration and achieved the expected results.
