在我国传统农业耕作过程中,农民就有随自然降雨或灌溉随水施用各种肥料给作物补充营养的习惯。但是因为浇水量不确定,所用肥料养分含量低、成分单一、水溶性差等因素,致使冲施肥效果不是很理想。如局部养分浓度高造成烧苗,离水源远的地方养分浓度过低而没有肥效等。虽然冲施肥料有

In China’s traditional agricultural farming process, farmers have a natural rainfall or irrigation with the use of various fertilizers to crop nutrient-rich habits. However, because of the uncertainty of watering amount, the nutrient content of fertilizers used is low, the components are single, the water solubility is poor and other factors, resulting in the impulse fertilization effect is not very satisfactory. Such as the local high concentration of nutrients caused by burning seedlings, far away from the water nutrient concentration is too low and no fertilizer and so on. Although red fertilizers have
