A barrier frame for limiting the growth area of ​​herbaceous plants and its growth limiting method

Abstract

The invention discloses a barrier frame for limiting the growth area of ​​herbaceous plants and a growth limiting method thereof. Border frame or irregular pentagon frame, the barrier board is extruded polystyrene foam board; without affecting the normal growth of plants, it can effectively block the rhizome of the target plant and limit the growth of the target herb in the barrier frame , to prevent it from being mixed with other plants due to vegetative growth, so as to ensure the purity of plant germplasm and achieve the design effect of germplasm preservation, cultivation characteristics or landscape display; extruded polystyrene foam board is used as a barrier board, which is easy to obtain , the material cost is low, and at the same time anti-aging, durable, non-toxic, non-polluting, light in texture, easy to construct, long-term use in the soil will not damage the soil structure.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a herbaceous plant area planting method. Background technique [0002] Regional planting of herbaceous plants is widely used in the preservation of economic plant germplasm, cultivation experiments, and greening of plant grounds. It is easy to control the herbaceous plants with weak invasion (no rhizomes), but the plants with rhizomes or rhizomes are often below the soil surface, which is not easy to be noticed and breaks through the artificially set planting area, resulting in germplasm mixing , The test error increases or the test fails, destroying the expected greening landscape of the planting design, etc. However, in this field, there is little research and no effective barrier methods. [0003] Existing barrier implementations include the following: [0004] ① Cement pool barrier: For example, the bamboo germplasm nursery of Nanjing Forestry University; the pools are built ...

AI Technical Summary

Problems solved by technology

[0004]① Cement pool barrier: For example, the bamboo germplasm garden of Nanjing Forestry University; the pools are made of cement and bricks as planting areas, so that the roots of plants in the pools cannot Intertwined growth; its advantage is that it is sturdy and durable, and it is suitable for perennial woody plants; the disadvantage is that for herbaceous plants, it destroys the field soil structure, the cost is high, and it is not conducive to landscape design changes

[0005]② River sand or yellow sand barrier: For example, the turfgrass germplasm nursery of Nanjing Institute of Botany, Chinese Academy of Sciences; each turfgrass variety or strain is arranged vertically and horizontally in rectangular plots, and Sometimes river sand is used as an isolation material; the advantage is low cost and easy implementation; the disadvantage is that plant roots can easily pass through the isolation zone (river sand), and the underground part is difficult for human eyes to observe, resulting in germplasm mixing

[0006]③ Brick barrier: For example, the Zoysia japonica seed selection nursery of Jiangsu Institute of Grass Industry; arrange cement bricks or fired bricks to form a rectangle The advantage is that the cost is low and the implementation is easy; the disadvantage is that the construction can be started. When the turfgrass grows in the community, the rhizome will not be effectively controlled, causing germplasm confusion, and will significantly increase the labor force. expenditure

[0007]④Soil barrier: For example, the turfgrass experimental garden of Nanjing Agricultural University; no other isolation materials are used, and the method of manual weeding is used to maintain the isolation between areas The advantage is that the construction cost is very low, the change is easy, and the soil is not damaged; the disadvantage is that the labor cost is too high

[0008] ⑤ Hard plastic barrier: mostly used for small-area garden planting plants; the advantage is that the material is light in texture and low in cost, and can effectively isolate the spread of underground rhizomes or foreign Damage to the root system; the disadvantage is that the material is not easy to obtain, needs to be customized, and the material is easy to age

[0009] ⑥ Potted barrier: mostly used for small-area planting; the advantage is that it is easy to obtain, easy to operate, and can be effectively isolated; the disadvantage is that the area is too small, or the cost varies Larger, poor planting effect on slightly larger plots

[0010]⑦Chemical agent barrier: some experts introduced foreign experience, plants are planted according to rectangular plots (or other shaped plots), and when the plants are full of planting plots, the plants are planted in stages every year Spray herbicides (contact type and systemic type) on the edge of the plot to block the spread of plant roots; the advantages are low construction costs, easy operation, less labor, and low operating costs; the disadvantage is that it has a better effect on ground isolation, but underground stem isolation The effect is poor, and it is not intuitive, and the herbicide pollution is heavy

[0011] ⑧ Polyethylene plastic cloth screen barrier: Polyethylene plastic cloth is used as a barrier (Rhizome Barrier) to limit the expansion of plant roots in foreign countries. It is mainly used to block the expansion of woody plants such as the roots of large trees or the underground stems of bamboos. The advantage of this kind of barrier material is that it is softer and easier to adapt to changes in the size or shape of different growth areas of plants. The disadvantage is that it is easy to age and crack
