Shuitu Baochi Xuebao[目的] 为了研究土壤磷肥和盐分及其交互作用对紫花苜蓿生长、磷营养和耐盐性的影响。[方法] 通过向[XC;% 102% 102]土中添加不同浓度梯度的磷肥(0,40,80,160 mg/kg,以KH2PO4的形式添加)和氯化钠(0,0.4,0.8,1.6 g/kg)进行温室盆栽试验,种植紫花苜蓿"甘农七号"。[结果] 紫花苜蓿地上部生物量和地下部生物量均随着磷肥施加水平的提高而增加,但随着盐分添加水平的提高而减少;施磷时植物的磷吸收量增加,当磷水平为160 mg/kg时,根、茎、叶的磷含量均达到最大 ...

, 2018 瞭解不同種類作物營養需求特性以及土壤與肥料的性質，規劃合理適當的土壤及肥培管理，可提昇作物的產量與品質，發揮肥料效應，節省肥料資源，達到農業生產兼顧環境生態維護之境界。水稻在較低養分濃度環境下已能生長正常，在稻田狀況下，只要化學肥料使用足夠，作物生長被促進，收割後之殘株還原施用即維持一定的有機質含量，長期連用有機肥料之增產幅度不大，且有機肥料價格高於化學肥料，故在稻田可以不必提倡有機肥料之使用。有機米栽培應採用氮素含量高，磷鉀含量較低之高含氮量的豆粕類有機質肥料，較符合經濟成本 ...

Shuitu Baochi Xuebao, 2005 通过室内模拟培养和大豆盆栽土培生物模拟试验，研究了磷细菌溶解磷酸钙的能力及在北方石灰性土壤上施用磷细菌肥对土壤磷素转化的影响。试验结果表明：磷细菌菌株具有较强溶解磷酸钙的能力，磷酸钙的溶出率从第1天的2．80％提高到第8天的22．00％。在贫速效磷和富难溶性磷土壤上施用溶磷细菌肥有利于土壤中难溶态的Ca10-P和缓效态Ca8-P含量下降，促使土壤中Ca2-P和Al-P的含量增加，从而使土壤中有效磷含量增加。而对于富速效磷的土壤，无论施菌肥与否对土壤中各种形杰的无机磷绢分基本没有影响．
