There are two kinds of fertilization methods for the fertilization of vegetable in the protected area: sublime ditch and fertilization.
The submucous sulcus fertilization method is a method of topdressing fertilization used for cultivating vegetables in ridges. The main advantages of the fertilization method are: small fertilization range, less watering of single ditch, and better uniformity of fertilization; after fertilization, nutrients directly enter the main distribution area of ​​roots with water, which is beneficial to nutrient absorption and use. The main disadvantage of the flushing method is that the watering amount of the furrow is small, the watering time is short, and it is not suitable to directly fertilize with the solid fertilizer. The fertilizer needs to be dissolved into the water in advance, and the fertilizer is used for flushing.
The submucosal sputum surface fertilization method is a method of topdressing fertilization used for low-cultivation vegetables. The main advantage of the fertilization method is that the kneading surface is wide, the watering amount is large, the watering time is long, and the fertilization is easy. The main disadvantage of the flushing method is that the watering range is large, the fertilizer is often unevenly distributed on the kneading surface, and the fertilization quality is poor. In addition, after fertilization by the fertilization method, the fertilizer liquid is directly soaked in the root portion, and when the fertilization concentration is too high, it is easy to cause damage to the root system.
