Growth and growth in celery, spinach, chrysanthemum and amaranth and other vegetables at the seedling or growing late, with 10 ~ 20ppm gibberellic acid (920) solution spray, can promote growth, early harvest, yield 10% to 40% 10 to 15 leaves of lettuce, can be harvested in advance. Yield 12% to 48%. Prophylaxis long, nurturing seedlings in the greenhouse nursery, with 50 ~ 100ppm of low-prime solution or 0.2% ~ 0.4% of the long-lasting solution or 100 ~ 150ppm paclobutrazol solution, spraying at the seedling stage to prevent the growth of young , So that seedling leaf color dark green, internodes shortening, robust plant growth, increased drought, cold and disease resistance.
