红壤是衢州市重点开发的土壤资源,据第二次土壤普查,全市红壤面积达570万亩,占全市土壤总面积的45.8％。为了解决稂棉、棉经争地矛盾,实现浙江省政府关于棉花生产“稳东扩西”的战略决策,开辟棉花新基地,八十年代末九十年代初我市开始了在新垦红壤上的植棉试验,并取得了一定成果。新垦红壤的立地条件与棉花稳产高产的要求相距甚远,新垦红壤普遍存在酸、粘、瘦、旱等问题。土壤酸度高,pH 值低于5.5的红
Red soil is the key developed soil resource of Quzhou City. According to the second soil survey, the red soil area of the whole city reached 5.7 million mu, accounting for 45.8% of the total soil area in the city. In order to solve the contradictions between cotton and cotton, and achieve the strategic decision of Zhejiang provincial government on “stabilizing the east and expanding the west” of cotton production and opening up a new cotton base, the city started the new red soil cultivation in the late 1980s and early 1990s Cotton-planting test, and achieved some results. The site conditions of the newly reclaimed red soils are far away from the requirement of stable and high yield of cotton. Problems such as acid, stickiness, leanness and drought prevail in the newly reclaimed red soils. Soil acidity, pH below 5.5 red
