Silicon fertilizer can be widely applied to the trees of apple, pear, peach, grape, jujube, banana, citrus, litchi, longan, pomegranate, bayberry, mango and other fruit trees. As a kind of base fertilizer, the application amount of silicon fertilizer is different for trees of different ages as well as the fertilizer effect will be better if you mix silicon fertilizer with organic fertilizer. In addition, as a kind of topdressing fertilizer, silicon fertilizer is the necessary fertilizer for the whole growth period of fruit trees, especially in the latter absorption period. The effect of silicon fertilizer is also better, top dressing can be sprayed or directly apply into the soil.
The first application method is cave method, digging 10 to 20 cone hole one meter from the trunk, the depth should be 40 to 50 cm from the trunk, the mouth diameter should be 30 cm, the bottom diameter should be 10 cm . You can fill the hole with organic fertilizer and silicon fertilizer, and then cover the mouth with plastic cloth. In addition, top dressing and watering should be conducted in the hole.
The second method is ring ditch. The ring ditch method is that you should a ring groo
ve outside of the canopy, the width should be 30 to 40 cm, the depth should be 30 to 45 cm. You can mix silicon fertilizer and other base fertilizer into the ditch and then cover with soil.
The third method is the radial ditch. The radial ditch is that you should dig 6 to 8 radial ditches where 1 meter away from the trunk, the width should be 30 to 60 cm and the depth should be 30 to 45 cm. In addition, you should mix the silicon fertilizer with organic fertilizer and then apply them into the ditch.
Fourth, the strip ditch. You should ditch 1-2 strip ditches, the width should be 50cm, the depth should be 40 to 50 cm. You can mix silicon fertilizer with organic fertilizer into the ditch and then cover with soil.
Fifth, the whole garden fertilizer method. The silicon fertilizer and organic fertilizer should be evenly mixed and sprinkled into the whole garden, and then till the soil which the depth should be 25 cm. This method mainly used for roots application.
Matters need to attention
First, silicon fertilizer should be used with organic fertilizer, and pay attention to the scientific collocation of nitrogen, phosphorus, potassium, silicon.
Second, the silicon fertilizer can not be mixed
with ammonium and it is no matter with whether it is used for base fertilizer or topdressing fertilizer because the chlorine will volatile from carbon ammonia so that reduce nitrogen utilization.
Third, silicon fertilizer is cheap and it can also improve the soil quality. Therefore, it is recommended timely and continuously applied.
Fourth, the silicon fertilizer should be stored in a dry place. If there is caking, you can crushed it and applied it to soil, the fertilizer effect is still valid.
Fifth, the application of silicon powder is easy to lead to dust flying, when you want to use silicon fertilizer, you can mix the fertilizer with the wet soil.
