The invention relates to an improved American red maple twig cutting propagation method and belongs to the technical field of plant cultivation. The improved American red maple twig cutting propagation method comprises the steps that (1) a disinfected hot bed is set up on a selected breeding ground, arc frames are arranged on a seedbed, and disinfected cutting mediums are laid in the seedbed; (2) a half-lignified twig is cut from an improved American red maple maternal plant, and the twig is cut into a cutting slip with a length of 8-10 cm and with two buds and two pieces of half leaves; (3) the lower incision of the cutting slip is soaked in rooting agent, rooting powder solution, and hormone solution to facilitate rooting; (4) the cutting slip is inserted in the seedbed mediums, the depth of insertion is 2-4 cm, the density is that the space in the rows is 5cm and the space between rows is 6 cm, and the leaves face the same direction; and (5) the mediums are watered thoroughly after the cutting slip is implanted in, then a plastic thin film and a shading net are covered on the arc frames, and management after implanting begins. According to the improved American red maple twig cutting propagation method, the operation is simple without restrictions of regions and weather conditions, the speed of reproduction is fast, rate of survival is more than 95%, an improved American red maple seedling obtained is developed in root system and good in quality, and thus market prospects are broad.

The invention provides a humic acid water-soluble fertilizer which comprises the following components (expressed in mass percent): 0.8 to 8.4% of potassium fulvicate, 5.6 to 21.4% of diammonium phosphate, 0.12 to 0.54% of ammonium molybdate, 0.125 to 0.575% of copper sulfate, 0.1 to 0.4% of ferrous sulfate, 0.8 to 3.6% of boric acid, 3.8 to 12.5% of potassium dihydrogen phosphate, 0.75 to 1.75% of zinc sulfate, 0.25 to 1.15% of manganese sulfate and 57.5 to 75.5% of water. According to the invention, fulvic acid and essential nutrients for plants are used as components of the fertilizer, plant nutrients are in a reasonable ratio, and the humic acid water-soluble fertilizer is characteristic of capacity of significantly promoting early maturity of and preventing premature senility of grain crops and economic crops like fruits and vegetables.

The invention discloses a chrysanthemum cutting rapid rooting method. The chrysanthemum cutting rapid rooting method includes the stages of site preparation, chrysanthemum cutting preparation, cutting and rooting period management. The chrysanthemum cutting rapid rooting method particularly includes the following steps: site preparation, namely making a seedbed and laying a layer of sand on the seedbed, chrysanthemum cutting preparation, namely tidying chrysanthemum cuttings and placing cutting positions at the lower portions of the chrysanthemum cuttings in conditioning fluid, cutting, namely cutting the chrysanthemum cuttings in the seedbed, and rooting period management, namely conducting appropriate leaf surface spraying water supplement according to weather situations. By the adoption of the chrysanthemum cutting rapid rooting method, the chrysanthemum cuttings can root 2.5mm roots in 7 days, a rooting period is shortened by at least 5 days on a year-on-year basis, rooting speed is high, the roots are tidy, the rotten phenomenon is few, and operation and management are easily conducted.
