Embodiment 1
[0022] 1 material
[0023] The 4-year-old thin-shell hickory cultivar 'Boni' tested were all grafted seedlings, and the rootstocks were seedlings cultivated from natural mixed and strong seeds. The experiment was carried out from June 2014 to December 2014 at the production base of Nanjing Lvzhou Pecan Technology Co., Ltd. in Shanbei Village, Liuhe District, Nanjing.
[0024] 2 methods
[0025] Experimental truncation was performed on June 14 and June 28, 2014, respectively. In the experiment, the 20-50cm and larger than 50cm annual branches on the periphery of the canopy were selected for short-cut treatment, and six treatments were set up for short-cut treatment, namely no short-cut (control), topping, short-cut 1 / 5, short-cut 1 / 3. Short cut 1 / 2 and short cut 2 / 3 are numbered and listed, and 3 branches are trimmed for each treatment. Each treatment of 3 plants was regarded as 3 repetitions. In December 2014, count the number of sprouted shoots and measure their length. ...

[0033] Method (one), a kind of method of fast cultivating pecan crown of this patent, carries out by following method:
[0034] 1) Seedling selection, select height 1.5m, ground stem more than 1.5cm the 2-year-old thin-shell hickory root-rich container grafted seedlings.
[0035] 2) Land selection and land preparation, select land with fertile soil rich in organic matter, and plant leguminous crops such as soybeans for land cultivation, and then use an excavator to plow the land about 1m deep.
[0036] 3) Plant in December every year, dig a pit with a diameter of 1m and a depth of 80cm, spread 20kg of decomposed organic fertilizer on the bottom, and then spread 20cm of soil, and finally plant the seedlings. Cut off the above part to dry.
[0037] 4) The management of the first year after planting is mainly water management to ensure sufficient water and ensure the survival of the tree.
[0038] 5) The management of the first 2-5 years after planting mainly adopts the method ...

Abstract
The invention discloses a method for quickly cultivating a carya pecan tree crown. The method for quickly cultivating the carya pecan tree crown includes that selecting a 2-year-old carya pecan grafted seedling, planting, trunk determining, shearing according to the following method after planting for 2 to 5 years, to be specific, shearing in summer in general, shearing at the middle ten days of June of each year, cutting back 1 / 5 from each 20 to 50 centimeters one-year-old branch, and cutting back 1 / 3 from each more than 50 centimeters one-year-old branch; applying 20 to 40 kilograms of chicken manure and 1 to 5 kilograms of slow release fertilizer to each tree in winter of each year; irrigating duly to guarantee enough moisture; manually catching trunk boring insects and using an insecticidal lamp to kill the trunk boring insects. A lot of branches can be formed to quickly form the tree crown after planting for 5 years, the branch number is 3 to 4 times of that of the tree crown not sheared, and the yield would be increased by 3 to 4 times.
Description
technical field [0001] The invention belongs to the technical field of fruit tree and tree cultivation, and relates to a method for quickly cultivating a thin-shell hickory tree crown. Background technique [0002] Carya illinoensis (Wangenheim) K. Koch, also known as American hickory and long hickory, is a deciduous tree of the genus Carya Nutt in the family Juglandaceae. Pecan nuts with thin shells are rich in unsaturated fatty acids and have high nutritional value. They are famous high-grade dried fruits and edible oils in the world. Thin-shelled hickory was introduced into my country in 1900, but it has not been paid attention to and developed. At present, the thin-shelled hickory in China is mainly a fruit tree. The size and quality of the fruit vary greatly, and the commodity value is low. Since the beginning of the 21st century, the hickory nut industry has been highly valued, and scientific researchers have successively solved the problem of hickory seedling cultiva...
