Embodiment 1

[0081] In the present embodiment, the large saplings of the 15-year-old Chinese chestnut varieties 'Yanming' and 'Zaofeng' and the 4-year-old Chinese chestnut variety 'Yanguang' are planted by the method of the present invention, all of which are purchased from the seedling company of Changli Fruit Tree Institute, Hebei Province. The specific operation steps are as follows :

[0082] 1 Select the planting period

[0083] The planting period of chestnut trees began on April 10.

[0084] 2 big tree tree body pretreatment

[0085] 2.1 Root removal treatment of large trees before planting

[0086] On April 10th, 12 chestnut varieties 'Yanming', 'Zaofeng' and 'Yanguang' were selected to be planted at the nursery stock base of Changli Fruit Tree Institute Seedling Company in Hebei Province, of which 'Yanming' and ' Zaofeng'cuts roots vertically at a distance of 30cm from the trunk.

[0087] 2.2 Tree pruning before planting

[0088] The crowns of the three chestnut varieties wer...

Abstract

The invention discloses a bare-toot planting method for a large chestnut tree. The method comprises the following steps of 1, selecting a planting period; 2, pretreating a tree body of the large tree; 3, lifting seedling; 4, transporting; 5, planting, and carrying out water retention; and 6, carrying out maintenance and green-recovering. The method has the advantages that 1, the early spring with minimum transpiration amount of the tree body is adopted as the planting period, and five comprehensive water retention measures of (1) adopting a branch reshaping method of cutting 1 / 2 to 2 / 3 main branches of the planted large tree; (2) smearing cuts of the cross section; (3) adopting a root comprehensive moisturizing method after the seedling lifting of the large tree; (4) dewatering for two times after planting; and (5) covering mulching films, so the moisture transpiration amount of the tree body is reduced, and the survival rate of the planted large tree is improved; 2, the bare-root planting method is adopted, a root system only remains little heart protecting soil, and the integral weight and volume of the large tree are only about 1 / 4 of the weight and volume of a plant with soil, so the manual operation is convenient in the seedling lifting, transportation and planting processes, the labor workload is greatly reduced, the machinery assisting operation rate is reduced, and the planting cost is obviously reduced.

Description

technical field [0001] The invention relates to the field of fruit tree planting, in particular to a bare-root planting method for large chestnut trees. Background technique [0002] Seedlings with a seedling height of 1.5-2.0m, a trunk diameter of 4-5cm in diameter, 4-year-old seedlings with 1-2 layers, and 4-6 main branches are called "big trees" in fruit tree gardening [Zhang Xingwang. Cultivation techniques for large seedlings of fruit trees. Yunnan Forestry, 2008, 29(3):23.]. Planting big trees and building gardens will be the development trend of the fruit tree industry in the future. At present, due to the constraints of economic conditions and chestnut planting technology, the realization rate of chestnut tree planting and gardening in my country is extremely low. Trace it to its main reason, because in the chestnut industry of our country at present, there is not yet a kind of standard and high survival rate big tree planting technology. [0003] Nowadays, the te...
