充分用地,积极养地是农业增产的中心环节。万物土中生,土地是农业生产資料,地力是农作物产量的基础。合理的用地养地,必須与气候、土壤、水利、肥料、劳畜力等自然条件和生产条件相适应,做到用中有养,养中有用,使土壤肥力不断提高,农作物能够保持大面积均衡稳定增产。为了提高土壤肥力,不断地发展农业生产,最近省农学会与土壤学会联合召开了一次稻区用地养地学术討論会。会上交流了“八百斤地区”稻田用地养地經驗,鑑定了一批行之有效的养地措施,探索了今后用地养地的发展方向和进一步研究的方法。会議一致認为,合理的輪作換茬制度是用地养地的关键,而发展綠肥則是关鍵的关鍵。現将会議对稻区輪作換茬与发展綠肥問題的意見綜合整理如下,供大家参考。
The full use of land and active raising of land are the key aspects of increasing agricultural output. Everything in the soil, the land is agricultural means of production, land productivity is the basis of crop yield. Reasonable use of land to support land, and climate, soil, water, fertilizers, livestock and other natural conditions and production conditions to adapt to be used in the raising, useful in raising, so that soil fertility continues to increase, large areas of crops can maintain a balanced Stable increase. In order to improve soil fertility and continually develop agricultural production, the provincial agronomy association recently held a joint symposium on soil conservation of paddy land with the Soil Science Society. At the meeting, the experience of raising land for paddy fields in the “Eight Kgs of Area” was exchanged, a number of effective measures for raising land were identified, and the development direction and further research methods of land-use cultivation in the future were explored. The meeting agreed that a reasonable rotation crop rotation system is the key to land use, and the development of green manure is the key issue. Now the meeting on the rotation of rice crop rotation and development of green manure advice integrated into the following, for your reference.
