稻作旱种省水节能、便于操作、经济效益较高,我省关中各地近几年正在多点试验扩大示范。稻作实行早种之后,由于苗期生长较慢,田间空隙大,且湿润管理,有利于杂草大量出土和生长,严重影响稻作旱种的发展。根据陕西省农林技术推广总站安排,1985年我们在杨陵区李台乡永安村进行了稻作旱种化学除草试验。 Rice dry cultivation of water saving and energy saving, easy to operate, high economic efficiency, the province of Guanzhong in recent years are more experiments to expand demonstration. After the early planting of rice cultivation, due to the slow growth in the seedling stage, large gaps in the field and wet management, it is conducive to a large number of weeds unearthed and growth, seriously affecting the development of dry cultivation of rice. According to the arrangement of Shaanxi Provincial Forestry Science and Technology Extension Station, in 1985 we conducted a chemical weed-controlling experiment on dry cultivation of rice in Yong’an Village, Li Taizai, Yangling District.
