Problems needing attention in deep turning and ripening of plum and apricot soil

Deep plowing should pay attention to the problem is: deep plowing must be watered immediately, so that the soil and roots closely combined, otherwise easy to cause drought damage. If there is yellow silt or clay layer in the lower layer of the orchard on the flood plain, this layer of soil must be broken when deep ploughing, otherwise it is easy to form false high water level in rainy season, which is not conducive to root expansion. Deep ploughing depth should vary according to soil texture. Clay heavy soil should be deep, and backfill should be mixed with sand and organic fertilizer; Sandy soil should be shallow, but the lower layer is semi-weathered rock (crisp stone), it should be deep to thicken the soil layer; Mountain orchard deep gravel or gravel should be deeper, pick out large gravel; The soil with high groundwater level should be shallow, to prevent damage caused by connection with groundwater level. Deep turning should minimize root injuries, especially large roots. In case of large roots, the soil below the roots should be dug out, and the roots should be covered with wet soil immediately after exposure to avoid water loss of the roots. If root diseases are found, cut or scrape off the diseased parts and disinfect them with 5 Baume's sulfur mixture.
