Abstract

The invention discloses a prevention and control method for phenacaspis dendrobii kuwana of dendrobium officinale and application of the method. The method comprises the steps that a planting matrix containing plant smashing bodies is adopted and prepared from 10 parts of weak acid soil, 20-40 parts of thoroughly-decomposed earthworm excrement, 10-20 parts of peanut shells, 13-30 parts of wheat bran, 10-20 parts of lemon grass, 15-25 parts of bead tree leaves, 10-25 parts of red-knees herbs, 10-20 parts of soybean meal, 5-15 parts of vermiculite powder, 1-5 parts of potassium nitrate, 0.5-1.5parts of dicalcium phosphate and 1-3 parts of lysine; a nutrient solution containing a plant extract is adopted for spraying in the growth process and prepared from 5-25 parts of tobacco extract, 10-30 parts of rue extract, 10-25 parts of pyrethrum extract, 2-6 parts of magnesium sulfate, 1-5 parts of zinc nitrate and 1-3 parts of sodium carboxymethyl cellulose. The method is low in cost and needsfew working processes, the special planting matrix, the special nutrient solution and special growth hormones are adopted for being soaked, in combination with other treatment processes, the incidence of phenacaspis dendrobii kuwana of dendrobium officinale can be obviously lowered, and the effect is obvious.
