摘要
水稻是粮食作物和经济作物之一。大米也有潜力为增加农村地区的收入和就业作出重大贡献。从泰国和越南的大米进口情况可以看出，国内大米生产无法满足国内需求。本研究的目的是:(1)确定鲁武县水稻植物的实际和潜在土地适宜性水平;(2)找出鲁武县水稻植物的实际和潜在土地适宜性的限制因素。利用FAO方法评价水稻土地适宜性。基于土地特征的限制因素。结果表明，植物的实际土地适宜性为边际(S3fn)，限制因子为养分保留(有机C)和速效养分(P2O5和K2O)。通过添加59.6 t有机质ha-1、332.6 kg P2O5 ha-1、98 kg K2O ha-1来提高限制因子，使边际(S3)的实际土地适宜性变得非常适宜(S1)。
EVALUASI KESESUAIAN LAHAN PADI SAWAH (Oryza sativa L.) DI KABUPATEN LUWU
Rice is one of the food crops and commercial crops. Rice also has the potential to contribute significantly to increasing income and employment in rural areas. As indicated by rice imports from Thailand and Vietnam, national rice production has not been able to meet domestic demand. The objectives of this study were (1) to determine the actual and potential land suitability levels of rice plants in Luwu Regency and (2) to find out the limiting factors for actual and potential land suitability of rice plants in Luwu Regency. Evaluation of rice land suitability using the FAO method. Based on the limiting factors of land characteristics. The results showed that the actual land suitability of plants was marginal (S3fn) with the limiting factors for nutrient retention (organic C) and available nutrients (P2O5 and K2O). Efforts to improve the limiting factor can be made by adding 59.6 t organic matter ha-1, 332.6 kg P2O5 ha-1, and 98 kg K2O ha-1 so that the actual land suitability of marginal (S3) becomes very suitable (S1).
