Some grass flowers used during the National Day will often experience premature aging, affecting the display effect. In addition to the early decline of Cauliflower, the characteristics of the varieties, climatic conditions, and matrix preparation, inappropriate irrigation and fertilization, plant diseases and insect pests, insufficient accumulation of nutrients before flowering are also important factors. In order to enable people to enjoy the great festival of the Chinese nation, before and after the National Day, the following points can be used to manage the flowers. First, select in advance to bloom in the National Day, and in the "young and young" potted plants in the spare.

Second, the use of potted plants should be enough base fertilizer. From the buds to the flowering stage, thin pancake water containing 0.1% borax and 1/10 of fully decomposed chicken (geese) feces can be poured once a week. One or two days before the flower garden is planted, pour it with a thin pancake mixture containing 34% of pentachloropharmaceutical powder 800 times or 14% of multi-effect water-solubility agent 150 times to prevent root diseases. For the flowers in the early flowering stage, apply a nitrogenous fertilizer, such as a thin pancake mix with 2% urea. Third, the application of foliar fertilizer and spray to protect the leaves, the following few should be combined with watering implementation. 1. From the bud to the flowering stage, spray a mixture containing 0.1% boric acid, 0.2% urea and manganese sulfate, 0.02% ammonium molybdate, and 0.3% potassium dihydrogen phosphate once a week. In order to prevent pests and diseases, it can be combined with foliar fertilizer. Once every 10 to 15 days, spray once with 1% urea, 0.2% potassium dihydrogen phosphate, 1.8% diazepam diluted 1500 times, and 10% polymycin wettable powder diluted 600 Double the liquid mixture once. In case of rainy days, spray it once every five days. 2. From the bud to the flowering stage. A mixture containing 0.5 ppm of triacontanol, 0.01 ppm of brassinolide, and 0.2 ppm of Fuziol was sprayed once every 7 to 10 days. 3. In the flowering stage, spraying 1.8% of the solution of sodium nitroprusside with 6000 times of liquid or 1.2% of the solution of ammonium nitroprusside for 4500 times once a week. Fourth, other attention: in the first three to five days before the nursery to move pots; flowering watering should be carried out in the morning; timely removal of decaying flowers; to avoid man-made damage. The above points apply to the vast majority of flowers, and can be flexibly used according to different varieties.
