Organic water-soluble fertilizer is a refined powdery, fully water-soluble, high-content organic fertilizer. The basic feature is good water solubility, which can be directly absorbed and utilized by the roots and leaves of crops. It can be quickly dissolved in water, nutrients are more easily absorbed by crops, and the absorption and utilization rate is relatively high. It can be applied to spraying, spray irrigation, etc., to achieve the integration of water and fertilizer, saving water, fertilizer and soil.
Flushing fertilizer is also called water flushing fertilizer. It is a way of top dressing. In fact, it is to dissolve solid quick-acting fertilizers in water and fertilize with water. Flushing fertilization usually uses water-soluble chemical fertilizers, mainly nitrogen and potassium fertilizers. Through the combination of fertilizer and water, soluble nitrogen and potassium nutrients are infiltrated into the soil and then absorbed by the crop roots. Flushing fertilization means irrigation and fertilization, and some places have extensive management and even use flood irrigation to flush fertilizers. This fertilization method of flood irrigation can easily cause a large amount of loss of nitrogen and reduce the water use efficiency.
Expert advice:
1. Combine organic fertilizer and inorganic fertilizer. Although some fertilizers contain humic acid, most of the inorganic fertilizers are nitrogen fertilizers such as ammonium nitrate and urea. Vegetables grow well in the short term, but they lack long-term effects. Some fertilizers are mainly cake fertilizer (hemp seed cake, cotton cake, bean cake) and diammonium phosphate (or ammonium nitrate), and the effect is not good because the cake fertilizer takes a certain time to ferment.
2. Combine topdressing and flushing fertilization. The choice of fertilizer is mainly compound fertilizer, and the method of combining topdressing and flushing is adopted to solve the problem of fertilization for surface roots. On the other hand, topdressing can activate the soil layer, increase the root system, and alleviate the fertilizer effect.
