Fertilization should be based on organic fertilizers, supplemented by chemical fertilizers, and the principle of applying no more than 20 kg of pure nitrogen per mu.
   Fertilization method: base fertilizer: 5000 kg of high-quality decomposed organic fertilizer per acre , 8 kg of urea , 75 kg of superphosphate , 12 kg of potassium sulfate . Top dressing: When the diameter of the flower ball is 3 - 4 cm, 16 kg of urea per mu is combined with watering , and the middle and late ripe varieties can be increased by 1 time.
Dosing Pump Characteristic :
1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
