一、水稻在宁夏农垦生产中占据主要位置宁夏农垦系统三分之二的农场建立在地下水位高,盐碱大,必须经过改良才可以利用的原生湖滩地上。在生产实践过程中,学习并总结出当地“开荒种旱,缺苗过半;无沟种稻,种子白撂;开沟种稻,碱地生效”的改良利用盐碱滩地的经验,因而从一开始,水稻就在农垦系统的农业生产中占据 First, rice occupies a major position in the Ningxia reclamation production Ningxia farming two-thirds of the farm system to establish the ground in the groundwater level is high, saline-alkali, can only be used to improve the original lake beach. In the process of production practice, we learned and summarized the experience of improving the utilization of saline-alkali land in the local “wasteland drought-cultivation, lack of seedlings more than half; non-furrowed rice, white buckwheat; trenching paddy, effective alkali” At first, rice was taken up in the agricultural production of land reclamation system
