Red plum apricot is a deciduous fruit tree and the best cash forest in semi-arid Loess hilly regions of China. Since 1995, the distribution area of the apricot has spread in most of the water-limited regions, in China, and the yield and benefits of red plum apricot increase dramatically. Since 2017, China put forward high-quality development, and red plum apricot must carry out high-quality production. But, as the red plum apricot tree grows, low temperatures and frost, hazards of heart-eating insects and soil drying will appear, which seriously influence the yield, quality, and benefits of red plum apricot in turn. However, there are few reports on the method for High-quality production of red plum apricot. In this study, the effectiveness of different methods of controlling low temperature and frost and hazards of heart-eating insects and soil drying was estimated. The results show that the greenhouse method is the better method for controlling Low temperature and frost, spraying Beta-cypermethrin still is the better method for controlling Hazards of heart-eating insects. When the soil water resource in the maximal infiltration depth is lower than the soil water resource use limitation by red plum apricot, the plant water relationship enters the key period of plant water relationship regulation. The ending time of the critical period of plant water relation regulation is the failure time of plant water relation regulation. When the current plant density is more than the soil water vegetation carrying capacity, the plant-water relation should be regulated, and then the vegetative growth and reproductive growth on the appropriate leaf quantity when the current plant density is equal to the soil water vegetation carrying capacity and the leaf fruit relation.
