我场地处赣江支流沂江河畔,全场耕地面积2,193亩,其中水田1,793亩,由于地势较低而平坦,四、五月常受洪涝为害,全部只能种植一季晚稻。每个农业劳力,平均负担耕地9亩。我场1976年就开始推广杂交水稻,至1980年已全部杂优化。随着杂交水稻种植面积的扩大,单产逐年提高,1977年平均亩产838斤,1978年
My field is located on the banks of the Yi River, a tributary of the Ganjiang River. The total cultivated land area is 2,193 mu, of which 1,793 mu is paddy field. Due to low topography and flatness, it is often affected by floods in April and May and all can only grow one season of late rice. Each agricultural laborer, the average burden of 9 acres of arable land. My field began to promote hybrid rice in 1976, and by 1980 all the hybrids had been optimized. With the expansion of hybrid rice acreage, yields have been increasing year by year, with an average yield of 838 kg per mu in 1977 and 1978
