黄岩县位于浙江东南部,东临大海,三面陆地,地理位置是北纬28度40分,东經121度26分,基本上是个平原水稻地区。历年来,大力推广以連作稻为主的耕作制度,改变了过去大面积种植双季间作或单季稻的面貌,使水稻單位面积产量迅速提高。在貫彻改制的同时,栽培技术上也有很大的革新,由于連作稻面积的扩大,早稻的生长季节显著提早,过去老一套的育秧方法已不能适应目前生产发展的需要。58年播种期又比57年普遍提前,大面积推广
Huangyan County is located in southeastern Zhejiang Province, east of the sea, on three sides of the land, the geographical location is 28 degrees north latitude 40 minutes longitude 121 degrees 26 minutes, basically a plain rice area. Over the years, the promotion of the farming system based mainly on continuous cropping rice has changed the appearance of large-scale double-cropping or single-cropping of rice in the past and the output per unit area of rice has rapidly risen. At the same time of implementing the system reform, there has also been a great innovation in cultivation techniques. Due to the continuous expansion of the area under continuous rice cultivation, the growing season of early rice is significantly earlier. In the past, the old method of growing seedlings could no longer meet the needs of current production and development. 58 years sowing period than 57 years in advance, large-scale promotion
