农业要持续稳产高产,肥料是一个关键问题。据有关资料分析,农作物增产的诸因素中,种子的作用约占30％,水利的作用约占20％,肥料的作用约占50％。由此可见,肥料对于农业生产的至关重要作用。我国农业生产,一方面是化肥供应量不足,另方面又由于长期偏施化肥,产生了土壤板结、土壤肥力下降、作物品质变劣、肥料利用率低
Fertilizer is a key issue for agriculture to sustain stable and high yields. According to relevant data analysis, among the factors that increase crop yield, the role of seeds accounts for about 30%, the role of water conservancy accounts for about 20%, and the role of fertilizer accounts for about 50%. From this we can see that fertilizer plays an important role in agricultural production. China’s agricultural production, on the one hand, lacks supply of chemical fertilizers. On the other hand, due to long-term partial application of chemical fertilizers, soil compaction, decline in soil fertility, deterioration of crop quality, and low fertilizer utilization rate have resulted.
