Embodiment 1

[0017] This experiment was carried out in Longhetun, Buyao Village, Guohua Town, Pingguo City, Guangxi. The village is located in the south of Pingguo City, in the middle of the karst mountainous area in the southwest of Guangxi, adjacent to the Youjiang River Valley. In March 2019, the abandoned cultivated terraced land (referred to as terraced land) with a width of more than 2m and abandoned for 3 years was selected to carry out an experiment of using artificial stone trenches to improve the afforestation efficiency of Camellia sinensis. The tea stick seedlings are seedlings in nutrition bags, the seedling age is 6 months, the average plant height is 26.7cm, the average base diameter is 0.30cm, and the experimental observation period is 3 years. The test method and main steps are as follows:

[0018] (1) The plot test method was adopted, and a total of 4 experimental treatments were set up (6 replicates for each treatment, 5 seedlings for each replicate), and the schematic ...

Abstract

The invention discloses a method for improving the seedling planting and afforestation efficiency in a stony desertification region, which specifically comprises the following steps: firstly, selecting an afforestation region, and after seedling planting is completed, constructing an artificial stone ditch which contains seedling planting rows and has certain width and depth by using stones on site and taking seedlings as centers along the seedling planting row direction, a microenvironment suitable for nursery stock growth is created, nursery stock growth is promoted, and the seedling planting and afforestation efficiency is improved. The test result of the applicant shows that the construction of the artificial stone ditch remarkably improves the plant growth (including indexes such as average plant height growth, average base diameter growth and average single plant biomass) of the nursery stock, and effectively improves the seedling planting and afforestation efficiency.

Description

technical field [0001] The invention relates to a method for improving the efficiency of planting seedlings in rocky desertification areas, and belongs to the technical field of artificial afforestation. Background technique [0002] Planting seedlings is the most important method for vegetation restoration in rocky desertification areas. Due to its location in the subtropical zone, hot climate, large surface evaporation, long seasonal drought period, and poor soil layer and poor soil water retention capacity, it is very difficult to plant seedlings in rocky desertification areas. problems such as small volume and low comprehensive benefit. [0003] Camellia sinensis is an excellent native tree species in South China, with strong adaptability, and has a prominent role in promoting vegetation restoration in rocky desertified mountainous areas. The method of planting seedlings is mainly used for tea sticks, that is, the use of bare root seedlings or nutrient bag seedlings fo...
