红壤利用,在南方各省是扩大耕地面积、增加农作物产量的主要方向之一。但根据调查及利用上很多资料,都说明红壤有下列许多缺点:即保水保肥能力十分薄弱,像甘藷、花生、乃至於棉花,在红壤上都能生长,甚至可能长得很好,可是在生长後期遇到乾旱,就造成甘藷发裂、花生空壳、和棉花落蕾落铃种种的不良现象,大大降低收成;至於说到红壤酸度大和肥分含量低微等,就现有农作物品种的适应性,和一般耕作技术水平方面说,都还是比较容易克服的。因此在红壤的垦殖和利用过程中,
Utilization of red soils is one of the main directions in the southern provinces to expand the area of arable land and increase the yield of crops. However, according to the survey and the use of a lot of information on the red soil has the following shortcomings: water and fertilizer is very weak, like sweet potatoes, peanuts, and even cotton, red soil can grow, and may even grow well, but in In the late growth period, the drought will cause the sweet potato cracking, peanut shells, and cotton fall and fall bell all kinds of adverse phenomena, greatly reducing the harvest; As for the red soil acidity and fertilizer content is low and so on, to adapt to the existing crop varieties Sex, and general farming techniques, are still relatively easy to overcome. Therefore, red soil cultivation and utilization process,
