本文综合国内外一些有关的文献资料和我们调查研究的结果,着重研讨水稻缺磷问题、水稻土中磷的有效化、特别是采取适当的农业技术措施来提高水稻土中磷和施肥磷的有效度。目的在于挖掘水稻土中磷和施用较少量的磷肥及直接利用低品位的磷矿粉,以获得较高的稻谷产量并降低生产成本,希望对本省水稻缺磷问题的缓和以至解决,有所助益。
Based on the domestic and foreign literature and the results of our investigation, this paper focuses on the issue of phosphorus deficiency in paddy soils and the availability of phosphorus in paddy soils. In particular, we take appropriate agricultural techniques to improve the effectiveness of phosphorus and fertilizing phosphorus degree. The purpose is to tap the phosphorus in paddy soil and the application of relatively small amounts of phosphate fertilizer and direct use of low-grade phosphate rock in order to obtain a higher yield of rice and reduce production costs, hoping to alleviate the problem of lack of phosphorus to solve the province’s rice, Help.
