After topping the cotton to make up
After the cotton is topping, the plant organs compete for nutrient intensively. If the supply of nutrients is insufficient, the middle and lower parts of the plant will reduce or have no bell in the upper part, or the cotton bolls will have premature decay, leaves fall off and the boll weight will be reduced, and high yield will not be achieved.
After the cotton plants are topping, they are almost always flowering and ringing, and sometimes each plant produces 2 to several flowers per day. There is a constant demand for nutrients. After the topping, the growth advantage of the cotton top disappears, and the young bell after flowering becomes the strongest contender for nutrients. If the demand for nutrients cannot be satisfied by the young bell, the young bell will fall off. Generally, the young bell of 1 to 4 days after flowering is the most Easy to fall off; lack of nutrients can also cause the buds to fall off.
After topping, it can be supplemented with a combination of root fertilization and foliar spray. Fertilizers are mainly nitrogenous and potash fertilizers, applying 7.5 kg urea per mu and 7.5 kg potassium chloride. Phosphorus-deficient soil should be supplemented with phosphate fertilizer. Fertile oysters or organic fertilizers are used more often, and there are signs of intensive growth in cotton fields, and the amount of nitrogen fertilizers should be controlled. Plants can not be applied to nitrogen fertilizer in leggy and uncovered cotton fields. Phosphorus and potassium fertilizers should be added.

ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
