The invention discloses a method for synchronously preventing and controlling fruit
cracking and a fruit shrinking
disease of
ziziphus jujuba mill, namely, key mineral element supplementation, chemical prevention and
growth regulator application are combined. The method is characterized in that soil fertilization is carried out by mixing
potassium sulfate and
manganese sulfate according to a certain proportion, and
sodium silicate and
calcium chloride are sprayed on leaves, so that key mineral elements and beneficial elements can be effectively supplemented,
nutrient balance can be regulated, and the resistance is increased; 6-BA (Benzyladenine) is sprayed on the leaves in an early stage, so that pericarpic
cell division is stimulated, and elasticity of jujube peel is enhanced; NAA (
Naphthalene Acetic Acid) is sprayed in a later stage, so that maturing of jujube fruits is delayed, and a cloudy and rainy period in the early of mid September is avoided;
mancozeb is sprayed on the leaves, so that
pathogenic bacteria on
body surface can be effectively killed, a layer of dense protective
medicine membrane is formed on the surface of
crop, and
germination and invasion of the
pathogenic bacteria are inhibited. According to the method disclosed by the invention, the morbidity of the fruit
cracking and the fruit shrinking
disease of the
ziziphus jujuba mill can be synchronously and obviously reduced, and a total diseased fruit rate can be reduced from 80 to 100 percent to 20 percent or less. A technology is applied to prevention and control of the fruit
cracking and the fruit shrinking
disease of the
ziziphus jujuba mill, the method is simple, the cost is low, the prevention and control efficiency is high, and the effect is lasting.
