新疆地区,土壤有机质含量低,氮素贫乏。但随着农业生产的发展和氮素化肥施用量的逐年增加,致使土壤中氮磷此例失调。因此,近年来不少地区施用磷肥,增产效果显著,磷肥的施用面积逐年扩大。新疆不少地区有磷矿资源,应当充分开发这一资源,为农业生产服务。 一、磷肥对主要作物的增产效果 磷元素在农作物体内,主要参与能量转运和组成一些化合物。当什物成熟时。大部分磷素都由作物的营养器官转移到作物的种子和果实中。若磷肥供应不足,作物体内的氮、磷此例就会失调,化合物的生成和运转就会受到抑制,导致穗小、粒少、千粒重减轻,不能实现高产。 Xinjiang, soil organic matter content is low, nitrogen deficiency. However, with the development of agricultural production and nitrogen fertilizer increased year by year, resulting in the case of nitrogen and phosphorus in the soil disorders. Therefore, in recent years, phosphate fertilizer has been applied in many areas, and the yield increase effect has been remarkable. The application area of ​​phosphate fertilizer has been expanding year by year. In many areas of Xinjiang, there are phosphate rock resources, and this resource should be fully exploited to serve agricultural production. First, the phosphate fertilizer on the main crop yield effect Phosphorus in the crop body, mainly involved in energy transport and composition of some compounds. When something matures. Most of the phosphorus is transferred from the crop’s vegetative organs to the seeds and fruits of the crop. If the supply of phosphate fertilizer is insufficient, the nitrogen and phosphorus in crops will be imbalanced in this case, and the formation and operation of compounds will be inhibited, resulting in small spikes, fewer grains, and reduced grain weight, thus failing to achieve high yield.
