Abstract

The invention discloses a cultivation method for controlling pecan tree type and increasing yield thereof. The method comprises following steps: using soil applied paclobutrazol and performing summerpruning; the paclobutrazol application concentration: 1.0g to 1.25g paclobutrazol per square meter on pecan crown; the time for application: before germination; trimming and pinching in summer (May toJuly). The invention can control the diameter growth and length growth of the shoots of the current year, increase the number of short fruit branches, promote flower bud differentiation, increase thefruit retention rate and increase the yield, and provide scientific and technical support for the industrialization development of the American pecan in China.

Description

technical field [0001] The invention belongs to the technical field of economic forest cultivation, and in particular relates to a cultivation method for controlling the tree type of American hickory and improving its yield. Background technique [0002] American hickory (Carya illinoensis (Wangenh.) K.Koch), also known as thin-shell hickory and long hickory, is a plant of the genus Hickory in the family Juglandaceae, native to the United States and Mexico, and is an important dried fruit, edible oil, Timber and landscaping species. [0003] China has introduced and cultivated American pecans for more than 100 years, but it has not yet formed a mature and stable industry. The important reasons restricting the development of American hickory in China are: when the American hickory is young, the branches grow vigorously, the flower buds are less differentiated, the short fruit branches are less, the fruit drop rate is high, and the early yield and economic benefits are low. ...
