施肥在农业生产中的作用越来越突出。从国外到国内,从农业科研部门到农业生产单位都在研究和选择适于本地区的农作物施肥法,可以说这是一种技术改革,改革的方向就是把当地的经验施肥逐步变成测土施肥。因此,近几年来国内测土施肥技术发展较快,测土施肥面积逐年猛增。 新疆生产建设兵团垦区同其它省区垦区相比,尚有其特定环境下的问题:(1)从产量看——是需要大量肥料的。新疆光能充足。水源稳定,小麦大面积亩产四百公斤、玉米六、七百公斤已不是个别现象。产量高则需养分多,补充养分的途径,主要靠增施肥料。特别是新疆气候干旱,相对湿度低,蒸发强 The role of fertilization in agricultural production has become increasingly prominent. From abroad to China, from agricultural research departments to agricultural production units are studying and selecting suitable for this area of ​​crop fertilization, it can be said that this is a technical reform, the direction of reform is to gradually turn the experience of local fertilization soil testing Fertilization. Therefore, in recent years the rapid development of soil testing and fertilization technology, soil testing area soared year by year. Xinjiang Production and Construction Corps reclamation area compared with other provinces and reclamation area, there are specific problems in their environment: (1) from the output - is the need for a lot of fertilizer. Xinjiang light enough. Water sources are stable. Large-area wheat yields 400 kilograms. Six hundred or seventy kilograms of corn is no longer an isolated phenomenon. High yield requires more nutrients, ways to supplement nutrients, mainly by increasing fertilizer. Especially in Xinjiang, arid climate, low relative humidity and strong evaporation
