土壤科学土壤科学

背景情况:

均衡的营养对作物生产率至关重要,然而,巴基斯坦农民对 (K) 和 (Zn) 的应用却没有充分利用.
低于最佳的营养使用导致作物产量减少和肥料成本增加,影响农民的利能力和信心.
解决这一差距对于改善该地区的农业可持续性和经济回报至关重要.

研究的目的:

评估平衡的NPK和肥对小麦生长,产量和生理参数的影响.
评估不同肥料处理的营养回收和农学使用效率.
为优化巴基斯坦小麦营养管理提供基于证据的建议.

主要方法:

一项实地研究使用了五种治疗方法进行:对照,现有NP实践,推NP,平衡NPK和平衡NPK + Zn.
作为试验作物种植了小麦,并仔细测量了其生长,产量,生理和营养参数.
计算了营养回收效率 (NRE,PRE,KRE,ZnRE) 和农业使用效率 (NAUE,PAUE,KAUE,ZnAUE).

主要成果:

与对照组相比,平衡的NPK + Zn营养显著增加了植物高度 (13%),尖峰长度 (15%),光合作用率 (44%) 和谷物产量 (78%).
与NP单独应用相比,NPK+Zn的联合应用提高了营养回收效率 (NRE 230%,PRE 136%,KRE 135%,ZnRE 136%) 和农业利用效率 (NAUE 70%,PAUE 72%,KAUE 71%,ZnAUE 72%).

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
