浙江省鄞縣農場的土地,土質瘠薄,土壤粘重,耕作層淺。農場共有水田477.1畝,其中有100余畝“畈心田”(注一),土質十分瘠薄粘重,耕作層只有2—2.5寸。建場前,由于水利条件差,排灌困难,稍晴即旱,因此常年只能种植單季中稻,歷年平均畝產量只有150—220斤;建場后,積極改善土壤結構,提高土壤肥力,產量逐年有所增加。
Yin County, Zhejiang Province farm land, infertile soil, soil sticky, tillage shallow. The farm has a total area of 477.1 mu of paddy field, of which more than 100 mu are farmland (note 1). The soil is very barren and sticky, and the tillage layer is only 2-2.5 inches. Before the establishment of the site, due to poor water conditions and difficulties in drainage and irrigation, it was slightly sunny and dry. Therefore, single-season medium-sized rice could only be planted in all year and the average annual output per mu was only 150-220 kg. After the site was established, the soil structure was improved actively to increase soil fertility and yield Increased year by year.
