Large-cup seedling raising method for passion fruit autumn planting long-seedling-age seedlings

Abstract

The invention relates to a large-cup seedling raising method for passion fruit autumn planting long-seedling-age seedlings. The method comprises the steps of seed selection and seedling raising, strong seedling raising, old and weak root and branch and tendril pruning, new root growth promoting, large-cup seedling raising and the like. According to the large-cup seedling raising method, the problem that seeds cannot be adopted for seedling raising of the passion fruits at the high temperature in summer is solved, and the practical production problem that residual long-seedling-age seedlings planted in spring are discarded and wasted is solved. According to the method, after the remaining passion fruit seedlings after spring planting are subjected to pruning, new root growth promoting, large cup seedling raising and other treatment, the obtained passion fruit seedlings have good new seedling root systems after autumn planting, the normal and healthy growth characteristics can be kept, the problem of stem swelling in the later period cannot occur, and high yield and good quality of the passion fruits can be guaranteed after autumn planting in August to September.
