1.可以全面供应作物生长所需的养分。化肥的特点是养分含量高,肥效快而持续时间短,养分较单一;农家肥大多养分种类丰富,但含量低、肥效慢而持续时间长。因此,将化肥与农家肥混合施用可以取长补短。2.可以减少养分被固定,提高肥效。化肥施入土壤后,有些养分会被土壤吸收或固定,从而降低了养分的有效性。若与农家肥混施后,可以减少化肥与土壤的接触面,从而减少被土壤固定的机会。
1. Can fully supply the nutrients needed for crop growth. Fertilizers are characterized by high nutrient content, fast and short-lasting fertilizer, nutrients more than a single; most of the nutrient-rich manure, but the low content, slow and lasting a long time. Therefore, the fertilizers and manure mixed application can complement each other. 2. Can reduce nutrient is fixed, improve fertilizer efficiency. After fertilizer is applied to the soil, some of the nutrients are absorbed or fixed by the soil, reducing the effectiveness of the nutrients. If mixed with farmers fertilizer, fertilizer and soil can reduce the contact surface, thereby reducing the chance of being fixed by the soil.
