我国试验推广稀土微肥以来,北京、河北、湖南、广东等十多个省、市、自治区分别在小麦、水稻、大豆、棉花、蔬菜等作物上施用,都获得不同程度的增产效果。各地认为,稀土微肥能增强作物的抗寒抗旱能力,促进根系发达,植株健壮,增强作物对氮、磷、钾的吸收。我县去年在烤烟上进行试验,效果也很好 Since China experimented on the promotion of rare earth micronutrient fertilizer, more than ten provinces, cities and autonomous regions in Beijing, Hebei, Hunan and Guangdong have obtained different degrees of stimulation effects on crops such as wheat, rice, soybean, cotton and vegetables. It is believed by all parts of the world that rare earth micronutrient fertilizer can enhance the ability of crops to resist drought and drought, promote the development of root system, make plants robust and enhance the absorption of nitrogen, phosphorus and potassium in crops. Last year, my county conducted experiments on flue-cured tobacco and the effect was very good
