Paspalum natatum planting method for preventing water and soil loss

Abstract

The invention discloses a paspalum natatum planting method for preventing water and soil loss. The paspalum natatum planting method for preventing water and soil loss includes the steps of pit digging, seedling cultivation and field management. By using the characteristics that paspalum natatum is large in root biomass, and well developed in root, the paspalum natatum is planted into a pit laid with degradable materials, the roots of the paspalum natatum can only hover and accumulate on the bottom of the pit before degrading of the degradable materials, through drought stress, the roots of the paspalum natatum grow at the bottom of the pit in a hovering mode and then grow towards the ground with a little water directively, so that the root system of the paspalum natatum is in a lantern shape under the limitation of the space in the pit and tightly holds the soil in the pit, after the degradable materials are degraded, the root system of the paspalum natatum grows downwards again, and therefore the purposes of soil fixation, soil loss prevention and soil and water conservation are realized. The paspalum natatum planting method for preventing water and soil loss is simple in technology, convenient to operate, high in stability realization speed, good in effect and low in cost, and has a good effect and application value for soil and water conservation and vegetation recovery in the dry areas seriously lacking water.

Description

technical field [0001] The invention relates to a planting method of bahia grass, in particular to a planting method of bahia grass for preventing and controlling water and soil loss. Background technique [0002] Paspalum notatum Flugge is native to South America. It is also called Paspalum paspalum. It is a perennial creeping herbaceous plant of the Poaceae subfamily Paspalum. It can take root in the soil and stick firmly to the ground. Bahia grass has strong stress resistance and wide adaptability. Due to its large biomass and well-developed root system, it has good effects in water and soil conservation, environmental governance, plant purification, soil improvement, and use as lawn and forage. In the 1950s, my country introduced this species from the United States and the Philippines, and it has been widely used in grassland greening, road slope protection, and rocky desertification control. [0003] At present, there are many descriptions of the planting methods of ba...

Problems solved by technology

[0003] At present, there are many descriptions of the planting methods of bahia grass in slope protection lawn and desertification control (slope protection lawn and its laying method (CN200810044214.3), the method of planting trees and shrubs in the same hole (CN02160200.X), slope protection and greening methods and devices (CN200310111314.0), etc.), but most of them focus on the ratio and planting method of Bahia grass mixed with other grass species (a method for controlling rocky desertification through bioengineering (CN201210131635.6) ), mainly aimed at interplanting Bahiagrass and other grass species in slope protection areas and rocky desertification areas. , in areas where the soil is compact and soil erosion is not too serious, it has played a good role in protecting and improving the ecological environment, but for areas with loose soil, serious soil degradation, soil desertification, soil erosion, and extremely serious soil erosion, Conventional planting methods cannot effectively fix soil, prevent soil erosion, and maintain water and soil, especially in areas with arid climate and severe water shortage. Many plants are difficult to survive in dry and hot weather, and the vegetation coverage is relatively low. low, the ecosystem is fragile, soil erosion and soil erosion are serious, vegetation restoration is extremely difficult, and conventional planting methods can no longer meet the needs of ecological restoration
