Application method of water-soluble fertilizer
Technical Field
The invention relates to a use method of a water-soluble fertilizer.
Background
By research and development, israeli invented a drip irrigation method, one of the most widely known irrigation techniques in the world today, 36 years ago. The drip irrigation method can be used for precise fertilization and has the effects of saving water and fertilizer. Water-soluble fertilizer starts late in China, at present, drip irrigation equipment of Israel is mostly adopted by drip irrigation equipment, however, the inventor finds out by long-term visit that the condition that the water-soluble fertilizer floats up the spiral roots exists in crops which are subjected to drip irrigation by using drip irrigation facilities and are planted by using the water-soluble fertilizer, even if the drip irrigation equipment and the water-soluble fertilizer are purchased in Israel, the water-soluble fertilizer is diluted by using a pump, the diluted water-soluble fertilizer is pumped into a pipeline for drip irrigation, and the conventional operation of the drip irrigation facilities is stopped after the water-soluble fertilizer is completely dripped, so that the problem that the spiral roots float up the spiral roots still exists, the effect of increasing the yield of the crops cannot be achieved, even the yield is reduced, and.
Meanwhile, the inventor also finds that the existing water-soluble fertilizer is dissolved in water, clear and transparent, and the adopted natural water storage or underground well water is also filtered and has no substances capable of blocking a spray head, but in actual use, the problems of blocking the spray head and blocking a pipeline occur, and the popularization of the water-soluble fertilizer is troublesome.
At present, the problems that a nozzle is blocked and a pipeline is blocked when a clear and transparent water-soluble fertilizer after dissolution is used and the problem that a root system floats upwards to form a spiral root when an imported water-soluble fertilizer device and the water-soluble fertilizer are used for drip irrigation are not solved, so that the effect of increasing the yield of crops cannot be achieved, and even the yield is reduced.
