砂质低肥田施肥技术试验研究
Experiment Research on Technology of Applying Fertilizer for Crops in Sandy and Infertile Land
-
摘要: 通过四年田间试验研究,探讨了在砂质低肥土壤采用秸秆还田和过腹还田施肥技术;同时,进一步研究了秸秆还田和过腹还田对于冬小麦、夏玉米、花生生长和增产效果以及对土壤肥力、土壤理化性质的影响。试验结果表明,为使作物在砂质低肥田上获得节水高产稳产,逐步提高土壤肥力,改善土壤理化性质,施有机肥加适量化肥效果较好Abstract: Through field experiment for four years,the technique of applying fertilizer which is to return the straw to field directly or after the straw has been passed through the cattle's stomach was studied.The effects of both of the straw returned to field directly and after passed through cattle's stomach on the crop growth,soil fertility and physics-chemistry structure of soil were investigated in sandy and infertile land.
