Fertilization method for fertilizing fertilized vegetables

There are two fertilization methods for fertilizing vegetables in protected land, fertilizing under subterraneium fertilization and applying fertilization under surface plastic film.

The subterraneous film ditch fertilization method is a fertilization method used for ridge ridge cultivation of vegetables. The main advantages of this fertilization method are: the scope of fertilization is small, the amount of watering in a single ditch is also relatively small, and the uniformity of fertilization is relatively good; after fertilization, nutrients directly enter the main distribution area of ​​the root system, which is conducive to the absorption of nutrients and use. The main disadvantage of this fertigation method is that the ditch has less watering and the watering time is short. It is not appropriate to use solid fertilizers for direct fertilization. It is necessary to dissolve the fertilizers into the water in advance and use the fertilizer solution to flush them.

Mushroom surface fertilization under the plastic film is a low fertilizing method used for fertilizing vegetables. The main advantages of this fertilization method are the wide surface, large amount of watering, long watering time, and easy fertilization. The main drawback of this fertigation method is that the scope of watering is large, the fertilizer is often unevenly distributed on the surface, and the quality of fertilization is poor. In addition, after the fertilization method, the fertilizer solution directly soaks the roots, and when the fertilization concentration is too high, it is also easy to cause damage to the root system.
