Method for fast-growing high-yield afforestation of hackberries

Abstract

The invention provides a method for fast-growing high-yield afforestation of hackberries. The afforestation method comprises the following steps that (1) nursery stocks are chosen, wherein the nursery stocks which are robust, straight, upright, complete in root and free of plant diseases and insect pests are chosen; (2) afforestation is conducted; (3) cultivation management is conducted; (4) main diseases and insect pests are prevented, wherein slug moths, cotton aphids, plant louses and fall webworms are mainly prevented; (5) file management is conducted, wherein labor using and material consumption of various operations such as the positions and area of planting places, seedling sources, soil preparation, afforestation, cultivation management and the like are managed. According to the method, the robust nursery stocks with the ground diameters and the heights both achieving a certain level are chosen, then good afforestation lands are chosen for afforestation and planting, after soil preparation and base fertilizer application, the appropriate planting density is chosen for planting, then branches and trunks are trimmed after planting, and weeding and management of water and fertilizer are conducted. According to the method for fast-growing high-yield afforestation of hackberries, the cost is low, popularization is easy, the survival rate of afforestation can be achieved, forest stand plant diseases and insect pests can be lowered, the increment of forest stand plant average diameter at breast height is improved, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to an afforestation method for rapid growth and high yield of hackberry. Background technique [0002] Hackberry is a deciduous tree with a tall and majestic tree body, beautiful tree shape, rich greenery, and good shade effect. [0003] It is a good timber tree species and a good ornamental landscaping tree species. Hackberry is a positive tree species, slightly tolerant to shade, water and humidity, and has a certain ability to resist drought. It likes fertile, moist and deep neutral clay soil, and is also light-resistant. Saline-alkali soil, deep-rooted, well-developed root system, strong wind resistance, smoke resistance, dust resistance, and certain resistance to toxic gases. Now the cultivation time of hackberry is long, the stand effect is poor, and the economic benefit is low. The average DBH growth of lower hackberry trees is low, which is not conducive to the improve...

[0003] It is a good timber tree species and a good ornamental landscaping tree species. Hackberry is a positive tree species, slightly tolerant to shade, water and humidity, and has a certain ability to resist drought. It likes fertile, moist and deep neutral clay soil, and is also light-resistant. Saline-alkali soil, deep-rooted, well-developed root system, strong wind resistance, smoke resistance, dust resistance, and certain resistance to toxic gases. Now the cultivation time of hackberry is long, the stand effect is poor, and the economic benefit is low. The average DBH growth of lower hackberry trees is low, which is not conducive to the improvement of economic benefits
