Abstract

Abstract: Since 2017, China put forward high-quality development, and agriculture development has gone into a new stage of Agriculture High-quality development. 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 spreads in the most of the water-limited regions, China，and the yield and benefits of red plum apricot increase dramatically. Red plum apricot must carry out high-quality production, But, as the crown and root of red plum apricot tree grows and develops, Low temperature and frost, Hazards of heart-eating insects and soil drying will appear, which seriously influence the quality, yield and benefits of red plum apricot. However, there are few reports on the method for High-quality development of red plum apricot. After a couple of years study, the results show that greenhouse method and spraying brassicin according is the better methods for controlling Low temperature and frost, spraying Beta-cypermethrin 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 in the critical period of plant water relation, the plant water relation should be regulated by reducing the branches or leaf, 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. The diameter of the fruit is about 5 cm.
