What effect does winter irrigation have on fruit tree growth
Answer: Winter irrigation is also called frozen water. This watering is called frozen water for orchards. After the fruit tree enters the winter dormancy period, the nutrients begin to flow back from the tree body to the roots. In the years when there is little snow in winter, winter irrigation stores water in the soil, which increases the soil water content and prevents the occurrence of drought in winter and early spring. In addition, the increase in water content in the soil is conducive to the absorption of water and nutrients by the root system, thereby increasing the ability of fruit trees to resist freezing and drought, avoiding the drying of fruit trees due to physiological water loss, and ensuring the safe overwintering of fruit trees.

Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
I. Poly Aluminium Chloride Properties
1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants.
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants.
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility.
4. It is slightly corrosive and easy for operation.
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

Description: |
Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
Different grades of Polyaluminum Chlorides (PAC). The highly charged Al in the products is optimized for best performance for the different basicities of PAC. The low to medium basicity products are effective coagulants for treatment of both drinking water and waste water. And the medium to high basicity products are excellent for all ranges of wastewater treatment. |
III. Poly Aluminium Chloride Application:
1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.
2. It can lead to quick formation of flocculant (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
3. It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
4. The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different temperatures and at different regions.
5. Higher basicity, lower corrosive, easy for operation, and long-term use of non-occlusion.
