Problems solved by technology

Aiming at the problem that land resources cannot be fully utilized in the early stage of artificial planting of Maple japonica, according to the biological characteristics of medicinal materials, the intercropping and three-dimensional cultivation of shrubs and herbal medicinal materials with young forests of Maple japonica not only has high economic value and good ecological benefits, but also It can protect precious plant resources well, not only effectively improve the ecologically fragile environment in karst mountainous areas but also increase the income level of local people, achieving a sustainable virtuous circle

Embodiment 1

[0027] The three-dimensional interplanting method of "trees + shrubs + herbs", that is, "half maple lotus + yellow-flowered water lotus + red-root grass" is adopted in the karst area for returning cultivated land, including the following steps:

[0028] 1. Forest land selection: In the southern karst mountainous area, choose flat land with fertile soil, good drainage, and no water accumulation or abandoned cultivated land on gentle slopes as the three-dimensional compound planting land for Chinese herbal medicines.

[0029] 2. Woodland cleaning: manual removal of all weeds and miscellaneous shrubs in the woodland.

[0030] 3. Dig half maple lotus planting pit: the row spacing between plants is 4m×4m, the tree rows run north-south, and the size of the planting pit is 80cm×80cm×60cm.

[0031] 4. Colonization of maple lotus: In winter, two-year-old seedlings of maple lotus with healthy growth and plant height of 1.0-1.5 m are selected for planting, and 4 kg of decomposed pig manu...

Embodiment 2

[0044] In the karst area, the three-dimensional compound interplanting method is adopted in the mode of "arbor + shrub", that is, "half maple lotus + yellow-flowered lotus".

Embodiment 3

[0046] In the karst area, the three-dimensional compound interplanting method is adopted in the mode of "arbor + herbs", that is, "half maple lotus + red root grass".

[0047] The following table 1 and table 2 show the plant morphology and yield parameters of red root grass in the second and third April of three-dimensional planting in examples 1 to 3, and the morphology and yield parameters of half maple lotus and yellow flower lotus in October; comprehensive consideration The various morphology and yield parameters of the three plants, the three-dimensional composite planting pattern of "half-flowered lotus + yellow-flowered lotus + red-rooted grass" is better than that of yellow-flowered lotus and red-rooted Before the production of lotus is formed, 891.9 kg of red root grass can be harvested per mu, and at the same time, it has little effect on the growth of yellow-flowered lotus and semi-maple lotus, which improves the planting income and land utilization rate.

Abstract

The invention discloses a method for interplanting traditional Chinese medicinal materials in karst area abandoned farmland in a stereoscopic compound mode. Different precious life-form medicinal materials including pterospermum heterophyllum Hance, polygala aureocauda Dunn and salvia prionitis Hance which can bring economic benefits to farmers and also can well adapt to local environment conditions are adopted; an efficient ecological traditional Chinese medicinal material stereoscopic compound planting mode is established in karst mountain area abandoned farmland, namely, the perennial shrub medicinal material polygala aureocauda Dunn is interplanted in a stereoscopic mode at the initial planting stage of pterospermum heterophyllum Hance, and the biennial medicinal material salvia prionitis Hance is interplanted under polygala aureocauda Dunn. 891.9 kg of salvia prionitis Hance can be harvested per mu before yield formation of polygala aureocauda Dunn, growth of pterospermum heterophyllum Hance and polygala aureocauda Dunn is hardly influenced by interplanting, the planting income is increased, land is saved, and a unique landscape is formed. The method has the prominent advantages that the land utilization rate and the planting income are increased by fully utilizing growth seasons according to the growth characteristics of plants based on the ecological niche principle, ecological benefits are good, the cultivation method is simple, and large-scale popularization is easy.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for interplanting Chinese medicinal materials in a three-dimensional compound mode in a karst area degraded land. Background technique [0002] my country is one of the countries with the largest land karst landform in the world. It is mainly distributed in the south of the Yangtze River, accounting for about 14.3% of the country's land area. Its ecosystem is very fragile. Once the karst vegetation is destroyed or improperly used, it is very easy to cause soil erosion and "rocky desertification", which is a major environmental problem that our country is currently facing after "desertification". Only by speeding up the construction of forest vegetation in rocky desertification areas and restoring and rebuilding the severely degraded ecosystem in karst areas as soon as possible can we fundamentally curb land rocky desertification. Ecological restora...
