Problems needing attention in deep turning and ripening of plum and apricot soil
The problem that should be paid attention to when deep ploughing is that it must be watered immediately after deep ploughing, so that the soil is closely combined with the root system, otherwise it is easy to cause drought damage. If there is a sticky plate layer formed by yellow silt or cement in the lower layer of the orchard on the river beach, the soil must be broken when turning deeply, otherwise it is easy to form a false high water level in the rainy season, and it is not conducive to the expansion of the root system. The depth of deep turning should vary according to the texture of the soil. The clayey soil should be deep and should be mixed with sand and organic fertilizer when backfilling; the sandy soil should be turned shallow, but when the lower layer is semi-weathered rock (crisp stone), it should be turned deeply to thicken the soil.
