In summer, the weather and climate change greatly, and it is a period of frequent occurrence of meteorological disasters such as strong winds and hail. Apple orchards should strengthen their defenses. For hail disasters, the road of mass prevention should be taken, that is, when hail occurs, hail-eliminating bombs should be launched into the hail cloud in advance to eliminate hail, and remedial measures such as top dressing and watering should be taken in time after hail.
For gale disasters, methods such as tying ropes and hanging branches should be taken at the right time before the disaster to prevent the strong wind from breaking and breaking tree trunks or branches to reduce the damage of gales. At the same time, summer is the peak period of nutrient consumption for apple trees, and premature aging often occurs due to insufficient fertility or waterlogging disasters.
In summer, in addition to timely topdressing to prevent premature aging, attention should also be paid to preventing waterlogging and waterlogging. Waterlogging is an important reason for the premature aging of apple trees, so the ditch should be cleared and drained in time, so that the ground is dry after the rain, the garden does not accumulate water, and the garden soil is dry.
