Autumn basal fertiliser: The basal fertiliser is generally applied in early September. At this time, the fertiliser has sufficient time to ripen, allowing the tree to be absorbed and used before it is dormant. At this time, the root of fertilization cutting soon healed and sprouted a large number of root absorption, and improve the absorption and utilization of the tree's fertilizer. The types of fertilization are based on decomposed farmyard fertilizers, with a small amount of fertilizer. In general, each tree planted with 50 to 75 kg of composted soil should not be too deep, and 40 to 50 cm is appropriate. The saplings can be casted with furrows, and the robust trees are spread out. If a deficiency is found in the tree, a small amount of trace elements can be properly mixed.
Deeply turning the tree plate: Before the peak of the autumn cherry root growth, combined with the application of basal fertilizer, the deep-turning of the tree plate can increase the amount of deep roots, preserve water, and increase the temperature of the ground. Weeds, leaves, weeds, etc. in the tree trays were cleaned up and burned in order to eliminate the overwintering worm and fungus sources.
Autumn pruning: combined with the growth of the tree, it can timely remove the dense branches, cross branches, overlapping branches, disease and insect branches, improve the ventilation of the canopy, and increase the tree vigor. Sharpen the wound with a knife and apply it with a 5 degree liquid of sulfur. Then apply a protective agent such as tung oil to prevent the wound from decaying.
The prevention and treatment of brown spot perforation: From August to September, it is a period of high onset, and the onset of wind and rain is severe. When the tree growth is poor, it can also increase the incidence. Symptoms: The diseased leaves initially produce purple-brown dots and soon expand into round-striped round spots with a diameter of about 5 mm. The edges of the lesions are almost black. In the later stages, brown molds appear on both sides of the diseased leaves. Control methods:
1. Strengthen cultivation and management, create good conditions for ventilation and light transmission, apply more phosphorus and potassium, and increase disease resistance.
2. Remove diseased leaves in the fall, join pruning to cut diseased branches, and reduce the source of infection in the coming year.
3. In the onset period, spray 65% ​​of zein zinc 600 times or 50% carbendazim 1000 times.
