在郎溪县境内郎川河以南丘陵地区,分布有广阔的一片红壤,面积约有二十七点五万亩,占全县总面积的15.4%。其中已垦面积勾一万四千二百亩,仅占红壤面积的5.1%。红壤大部份分布在十五度以下的缓坡丘陵上,这里气候温暖,雨量充沛,土层深厚,无霜期长,为垦殖农田、茶园,发展果木经济林的理想地方。但是,由于红壤瘠薄易旱,缺乏自然肥源,新垦区病虫孳生,低产不保收,加之目前劳畜力不夠,故一般对红壤开垦利用的面积还不大。随着生产的发展和劳畜力的充裕,这样地势平缓的红壤低丘陵,一定会很快被垦殖利用。对于如何合理开垦和利用改良红壤的问题,农民在长期生产实践中积累了相当丰富的经验,笔者结合工作进行了一些调查,现加以整理,略作报道,供有关方面参考。
In Langxi County, south of Langchuan River hilly areas, there is a vast distribution of red soil, an area of about 27.5 hectares, accounting for 15.4% of the total area of the county. Of which 14,400 mu have been reclaimed, accounting for only 5.1% of the area of red soil. Red soil is mostly distributed in gentle slope hills below fifteen degrees, where the climate is warm, abundant rainfall, deep soil layers, long frost-free period, and is an ideal place for cultivating farmland, tea gardens and developing economic forest of fruit trees. However, due to the infertile drought in red soil and the lack of natural fertilizers, pests and diseases of new reclamation areas are not well protected and low yields are not guaranteed. In addition, due to the shortage of livestock and poultry resources, the area for reclamation and utilization of red soils is generally not large. With the development of production and the abundance of labor and animal resources, such low-lying red hills with flat terrain will soon be exploited. As for how to reasonably reclaim and utilize the improved red soil, farmers have accumulated rich experience in long-term production practice. The author conducted some surveys in combination with the work, and now he organizes and makes some reports for the reference of relevant parties.
