Low yield and weak frost resistance of the Hongmei apricot [Armeniaca sibirica(L.)Lam] are the main problems faced by Hongmei apricot in Ningnan typical cultivation areas. In this study, the restricting factors and the corresponding countermeasures were discussed from four parts by the field investigation and the indoor analysis, including the late frost damage, the water and fertilizer management, the shaping and pruning, the disease, pest and rodent damage. The results showed that the frequent frost damage in late spring was the most direct environmental factor to result in the poor yield or failure of Hongmei apricot in Ningnan typical cultivation area; due to the poor water and fertilizer management and the absent shaping and pruning in the growth process, the aged fruit-bearing branches, the poor stress resistance and the lower fruit-setting rate were the main internal causes of resulting in the poor yield or failure. In Ningnan typical cultivation area, the disease and rodent of Hongmei apricot garden were mild, but the harm to peach fruit borer(Carposina niponensis Walsingham)was relatively serious. In order to promote the production of Hongmei apricot in Ningnan typical cultivation area, on the basis of comprehensive consideration of local climate resources and water resources, the suggestions are as follows:(1)because the frost frequency occurs in Ningnan Hongmei apricot typical cultivation area, it is necessary to select small terrain, small climate, set up the prevention from forest, avoid the frost, and reduce the frost damage by comprehensive utilization of the covering, irrigation, water spraying, smoke and cold-resistant substances in the frost event.(2)the management of water and fertilizer in apricot garden, and the growth vigor should be strengthened, and the resistance of apricot tree to stress should be improved. Those with irrigation conditions should be irrigated at the right time, those without irrigation conditions should be renovated to collected natural precipitation and to improved soil moisture, and soil moisture evaporation should be reduced by laying black ground fabric; for apricot gardens with serious soil water deficit, appropriate thinning should be made to reduce soil water consumption; compound fertilizer with high nitrogen content should be applied in germination stage, organic fertilizer should be applied after fruit harvest to improve soil fertility.(3)according to the age of the apricot tree, the apricot tree vigor, the planting density, etc., the shaping and pruning should be carried out to promote the robust growth of the apricot tree, enhance apricot tree vigor, and improve the apricot yield and quality.(4)the prediction of the apricot fruit borer should be carried out and comprehensively controlled.
