In fertilization should pay attention to the following points:
1. Pay attention to seedbed fertilization to "rich in the fetus," it is best to use organic fertilizer plus fertilizer. The application of chemical fertilizers should be controlled by the proportion of nitrogen added to phosphate fertilizers, and phosphorus fertilizers are particularly preferred for the use of ordinary calcium or calcium magnesium phosphate fertilizers.
2. Deep application of basal fertilizer, combined with organic fertilizer and inorganic fertilizer, in the absence of organic fertilizer, fertilizer varieties may not necessarily be selected as high-concentration compound fertilizers, and high-nitrogen compound fertilizers may not be selected as high-tower granules, but single-element nitrogen fertilizers may be selected. Gap calcium phosphate fertilizer, potassium potassium sulfate or potassium chloride can be. Phosphate fertilizer in the acid soil area is better than "calcium magnesium phosphate fertilizer."
3. The top dressing is mainly applied nitrogen and potassium fertilizers, pay attention to the combination of fertilizer and water, and the number of top dressings is divided into the first fruit inflating period and the urging fruit fertilizer; the second and third ear fruits are in the period of swelling fruits. Topdressing 3-4 times.
4. After entering the full fruit period, the ability of weak roots to soak up the fertilizers can be reduced. This can be done by spraying fertilizers from outside the roots, spraying aqueous solutions of potassium dihydrogen phosphate, calcium nitrate, borax, and urea, which will be beneficial to the subsequent growth of strong fruits. Reduce the incidence of umbilical rot.
Greenhouse Automatic Proportional Pump
Fertilizer pump mounted directly on the pipe, the kinetic energy of pipe flow to drives the pump to work at a set ratio to suck high erconcentration drug or quantitative fertilizer in to the pump. After mixed with the water and delivered to downstream. No matter How to change the water pressure, Drug or fertilizer will be mixed and discharged according to a certain proportion.
