Cultivation method for early fruiting and high yield of Carya cathayensis

Abstract

The invention discloses a cultivation method for early fruiting and high yield of Carya cathayensis. The cultivation method comprises the following steps of (1) cultivating a Carya illinoensis stock; (2) grafting the Carya cathayensis; (3) carrying out field planting in winter, selecting a flat land with higher underground water level, heavy soil and a pH value of 7.3 to plant at the planting density of 4*5 m, applying 10 kg of decomposed organic fertilizers to each seedling and watering thoroughly during planting; (4) preparing corresponding pollinizers according to the flowering time of the Carya cathayensis, wherein a fine variety Boni of the thin-shelled Carya illinoensis is selected as the pollinizers, and the preparation proportion of the pollinizers to the Carya cathayensis is 30 to 1. After plantation, 20 kg of organic fertilizers are applied to each plant every year, and if effective precipitation does not exist in 10 days, plants are irrigated for one time. Through the method, a cultural region can be broadened, so that early fruiting and high yield can be implemented.
