Each liter of the water treated by adopting the process contains the iron of 0.3 mg or less and the manganese of 0.1 mg or less, and the quality of the water meets the quality of inlet water of a chemical water treatment system in the power plant.

The invention provides a method for improving artificial hybridization of willow cut twigs. The method comprises the following steps: 1, bud twig collection and treatment, wherein an excellent single plant which grows robust and is free of plant diseases and insect pests and at the prime age is selected as a parent, and before buds begin to expand at the beginning of February, the twigs provided with buds are cut from the middle or upper portion of the crown in a selected mother tree, the diameter of each twig ranges from 1 cm to 2.5 cm, and the length of each twig is 1m; (2) after the twig is picked, conducting water planting on the male bud twigs in a greenhouse; placing the female bud twigs in shade for water planting, wherein the indoor temperature ranges from 8 DEG C to 11 DEG C, and the relative humidity ranges from 40% to 50%; three to five days later, moving the female bud twigs into the greenhouse for water planting together with the male bud twigs. According to the method, a soil culture method is adopted after the cut twigs are subjected to water planting and induced to root, the twigs are moved into flowerpots containing nutrient soil after root primordia emerge through water planting, for the bud twigs which are subjected to soil culture and root, a small amount of water is only supplied to the flowerpots when necessary, work such as pruning, cleaning and water exchange in the water planting process can be reduced, and labor and time are saved.
