Soil salinity severely affects cultivation in arid and semi-arid regions. It causes, among other things, an imbalance in the mineral nutrition of plants which results in yields’ decrease. One of the research’s approaches to mitigate the effects of these constraints is to look at the interaction between sodium chloride and phosphorus. The aim is to study the action of phosphorus to reduce the harmful effects of salinity. This study was undertaken in a greenhouse, in a pot of vegetation. The model plant used is Sorghum (Sorghum vulgar var rocket). The interaction NaCl (S) × P is carried out with four concentrations of NaCl (S0 = 0.1 dS m−1, S1 = 2 dS m−1, S2 = 8 dS m−1, S3 = 32 dS m−1) and four doses of TSP (PO = 0 mg/pot, P1 = 200 mg/pot, P2 = 400 mg/pot, P3 = 819 mg/pot), that is 16 (SP) processing. The results obtained made it possible to identify the effect of the SP processing on the morphological parameters, on the assimilation of the NPK's major elements, and on the accumulation of proline. They clearly showed that by adding phosphorus there was a remarkable improvement as the Sorghum displayed tolerance towards salinity. This improvement is manifested by an increase in stem height, dry material yield, nitrogen and phosphorus uptake, and proline accumulation. The results obtained suggest that Sorghum culture in saline medium (EC ≤ 32 dS m−1) is possible.

相互作用盐度研究：高粱施磷

土壤盐分严重影响干旱和半干旱地区的种植。除其他外，它会导致植物的矿物质营养失衡，从而导致产量下降。减轻这些限制影响的研究方法之一是观察氯化钠和磷之间的相互作用。目的是研究磷对减少盐度有害影响的作用。这项研究是在温室中，在一盆植物中进行的。使用的模式植物是高粱（Sorghum vulgar var Rocket）。NaCl (S) × P 的相互作用是用四种浓度的 NaCl (S0 = 0.1 dS m-1, S1 = 2 dS m-1, S2 = 8 dS m-1, S3 = 32 dS m-1) 和四剂TSP（PO=0mg/pot，P1=200mg/pot，P2=400mg/pot，P3=819mg/pot），即16（SP）处理。获得的结果可以确定 SP 加工对形态参数、NPK 主要元素的同化和脯氨酸积累的影​​响。他们清楚地表明，通过添加磷，高粱表现出对盐分的耐受性，从而有显着的改善。这种改善表现为茎高、干物质产量、氮和磷吸收以及脯氨酸积累的增加。获得的结果表明，在盐水培养基 (EC ≤ 32 dS m-1) 中进行高粱培养是可能的。他们清楚地表明，通过添加磷，高粱表现出对盐分的耐受性，从而有显着的改善。这种改善表现为茎高、干物质产量、氮和磷吸收以及脯氨酸积累的增加。获得的结果表明，在盐水培养基 (EC ≤ 32 dS m-1) 中进行高粱培养是可能的。他们清楚地表明，通过添加磷，高粱表现出对盐分的耐受性，从而有显着的改善。这种改善表现为茎高、干物质产量、氮和磷吸收以及脯氨酸积累的增加。获得的结果表明，在盐水培养基 (EC ≤ 32 dS m-1) 中进行高粱培养是可能的。
