Cultivating method for pecans

Abstract

The present invention provides a cultivating method for pecans, comprising the following steps of: (1) cultivation of rootstock seedlings; (2) management of the rootstock seedlings before grafting; (3) grafting time: grafting is performed when the daily average temperature is 25-30 DEG C and before the rainy season comes; (4) the grafting method: collecting thriving ligneous or semi-ligneous branches born in the current year as scion branches, removing compound leaves, keeping petioles which are 2-3 cm long, and soaking the petioles in water for 6-12 h; transversely cutting the upper and lower parts of a grafting bud, and vertically cutting the two sides of the grafting bud, so that the transverse cuttings are connected to the vertical cuttings, and the bud slice is slightly peeled; selecting a smooth surface 12-17 cm above the ground on the rootstock, peeling a piece of bark as large as the bud slice off the rootstock by using the same method, rapidly attaching the grafting bud to the place where the bark is peeled off, binding the grafting bud and the rootstock tight from bottom to top with a plastic strip, keeping 1-3 leaves above the connecting part on the rootstock and performing pruning, and removing all the leaves below the connecting part; and (5) management of grafted seedlings. The cultivating method increases the germination rate of pecans; and in addition, the grafted seedlings are high in survival rate, strong in growth potential and high in seedling rate, and the seedlings grow in an orderly and consistent manner and have developed root systems.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a method for cultivating pecans with thin shells. Background technique [0002] Walnut is an important dried fruit tree species, which has high nutritional value and has high medical and health care functions. Its dried fruit or processed products are in short supply and have been loved by people for a long time. Thin-shell pecan (Carya illinoinensis (Wangenh.) K. Koch) is called American pecan. The trunk is straight, the crown is nearly broad and oval, the root system is developed, and it is resistant to water and humidity. It can be planted alone or clustered on lakesides, lawns, etc. It is suitable for garden shade trees and street trees. The urban and rural afforestation tree species and fruit material dual-use tree species can be used to build large economic forests on both sides of the Yangtze River in Jiangsu Province. The kernels are edible, and the deliciou...

Problems solved by technology

Because of its low seed germination rate and slow growth of seedlings, it is difficult to raise seedlings, which affects its promotion and planting in China.
