time of application
Examples
- As a result , i will not be discussing factors such as the impact of price or yield uncertainty , the timing , depth and placement of fertilizer application , nor the effect of environmental factors such as moisture availability
因此对于诸如价格或产量的不稳定性、施用时间、施肥位置和深度以及环境因素如有效土壤湿度的影响等等将不予讨论。 - The information given in the risk management guide will provide farmers with greater flexibility in rates and timing of n application while helping reduce the economic and environmental risks associated with n fertilization
按照风险管理指导，农民可得到更灵活的有关氮肥用量和施用时间的信息，并减少因施肥带来的经济上及环境方面的风险。 - According to the principle of nutrient balance and water requirement in cotton , the sub - model for fertilization and water management was developed by integrating the effects of soil characters , variety traits and yield target . the submodel can make decisions on the suitable total nutrient and water rates and distributions among main growth stages , ratio of organic to inorganic nitrogen , and the ratio of base to topdressing fertilizer
根据平衡施肥原理和棉花水分需求规律，在综合考虑土壤理化特性、品种遗传特征、产量水平等因子影响的基础上，建立了具有系统性和普适性的棉花肥料及水分运筹动态知识模型，模型可以完成肥料总量需求，有机肥与无机肥的比例、基肥与追肥的比例、追肥施用时间、水分需求总量及其在各个生育时期的分配等。
