High-quality Production of Red Plum Apricot in Semiarid Loess Hilly Region of China

Zhongsheng Guo*

Red plum apricot is a deciduous fruit tree and the best cash crop 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, China and the yield and benefits of red plum apricot increased dramatically. Since 2017, China has put forward high-quality development, and red plum apricot must carry out high-quality production. But, as the red plum apricot tree grows, Low temperature and frost, Hazards of heart-eating insects, and soil desiccation will appear, and seriously influence the yield’s quantity, quality, and benefits of red plum apricot. 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 the Hazards of heart-eating insects and soil desiccation were estimated. The results show that the greenhouse method was the most effective for controlling Low temperature and frost, spraying Beta-cypermethrin is still 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 critical period ends when plant water regulation becomes ineffective of plant water relation regulation. When plant density exceeds the soil water vegetation carrying capacity, the plant water relation should be regulated, and then regulate the Vegetative growth and Reproductive growth on the appropriate leaf quantity when the plant density is equal to the soil water vegetation carrying capacity and the leaf fruit relation.
