First, strengthen water and fertilizer management. At present, the pear tree has entered fruit enlargement period and flower bud differentiation period and needs sufficient nutrient supply. Before and after the wheat harvest, the precipitation was low, the temperature was high, and the weather was dry, which seriously affected the tree's water supply. At this time, it is necessary to strengthen water and fertilizer management in a timely manner. First, we must top-up potassium sulfate-type high-nitrogen, phosphorus, high-potassium three-element compound fertilizer, top-dressing after watering, prevent flooding irrigation, so as not to cause roots. Second, to spray quick, low loss, rapid absorption of potassium nitrate compound fertilizer, potassium dihydrogen phosphate and Yongye life, promote leaf large, thick leaves, green leaves, Ye Liang, reduce pear deciduous.
Second, control the use of organic phosphorus pesticides. Organophosphorus pesticides have a irritating effect on the leaves of pear trees. In particular, the use of high concentrations, excessive use of the pesticides, and spraying at high temperatures can cause a large number of deciduous pear trees. Therefore, we must strictly control the use of organic phosphorus pesticides and the use of concentrations, can use other pesticides instead, it is best replaced with biological pesticides or pyrethroid pesticides, must be used, pay attention to the use of concentration, spraying time at 10:00 am Previously, after 4 pm, avoid high temperatures during noon.
Third, spray Bordeaux fluid. During the fruit enlargement period, spraying Bordeaux fluid to prevent and treat diseases can prevent rainwater from scouring, and supplement the copper and calcium elements of the pear leaves to make the pear trees grow vigorously. The thick green and dark leaves of the leaves reduce the early leaves.
