2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Hydromulch is spread immediately after a wildfire in order to reduce overland flow and prevent soil erosion.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

The research team of the University of Aveiro in collaboration with the fire Brigade and a private company applied the hydromulch in a burnt pine area burnt at moderate fire severity. Hydromulch was spreaded manually from a jet hose over a group of erosion plots, and both runoff and erosion were compared to an untreated group of plots.
The hydromulch was applied at a ratio of 3.5 Mg ha-1 providing an initial ground cover of 80%, and was found to reduce post-fire runoff in 70% and soil erosion in 83%.

Purpose of the Technology: Hydromulch has been particularly useful on steep slopes and strongly modified areas such as quarries, construction sites, and cut and fill slopes along roads (Robichaud et al., 2010). The hydromulch is a complex mixture which contain basically water and wood or paper fibers. Additionally it can contain seeds, surfactants, seed-growing biostimulants, nutrients and a green colorant. It is intended that each component affected some of the pieces of the post-fire runoff erosion process.
The high effectiveness in runoff reduction could be related to the effect of the wood fibers, because it increases the surface water storage capacity, but also due to the effect of the surfactants, a wetting agent that reduces SWR and increases soil infiltration. Ideally, post-fire hydromulching must be carried out immediately after the fire, over bare, unprotected and steep burnt areas. It is intended for places in which burnt severity was moderate to high and where there are very important values at risk, such as water reservoirs, populations, industries, human and wild life.

Establishment / maintenance activities and inputs: The hydromulch is applied once, immediately after the wildfire, aerially, from a tractor or also manually by using a jet hose operated by a person on foot. It basically consisted of a mixture of water, wood fibers and seeds. The seed composition should include autoctonous plant species, in order to avoid alien species into the burnt area and increase the germination success. Besides the composition, the application technique can influence the hydromulch effectiveness. Rough (2007) and Robichaud et al. (2010) reported that the hydromulch sprayed from vehicles was intercepted by the standing trees, and they recommended special caution when applying the mixture in areas with a high density of dead trees and from long distances. Aerial hydromulch can be a better and less expensive option, but Hubbert et al. (2012) checked that the intended application rates of 50% and 100% hydromulch cover resulted in only 20–26% and 56%.

Natural / human environment: The natural forest in central Portugal has been substituted by pine and eucalypt trees that are typically planted as monocultures for wood and paper pulp production. The landscape reflects a long history of intense land management, with a mosaic of (semi-) natural and man-made agricultural and afforested lands. In recent years, however, wildfires have increased dramatically in frequency and extent, and have been associated to soil fertility losses, and consequently to socio-economic losses.

ຄວາມຄິດເຫັນ:

The prices were determined in winter 2009 for central Portugal. In other regions and for other formulations these prices can vary. When compared with straw mulch its price is extremely high, but despite this greater expense, hydromulching has been used especially in the USA after some fires when access was difficult, the slopes were too steep or subject to wind to use straw mulch and when there were particularly important ‘values at risk’, such as water reservoirs, cultural or natural heritage sites, national or regional wildlife protected areas or industrial plants

Accessibility and steepness will raise the costs, but selecting hydromulchings is also a main factor. The more complex the hydromulch the more expensive the application cost. Hydromulch with seeds have also the possibility of introducing invasive plants into the ecosystems and increase the costs. For large and inaccessible areas the aerial hydromulch can reduce the costs.

Hydromulch is very expensive when compared to straw mulch, but not more effective in post-fire soil erosion reduction.	To develop hydromulch mixtures using the lowest amount of water as well as other chemical components to the minimum.
Some researchers found very low performance due to the interception of the hydromulch jet by the dead standing trees	Verify when applying it that the ground coverreach a minimum of 60%
Sometimes the mulch component (wood fibers, chopped paper) can be removed very easily by heavy rainfall, and thus treatment effectiveness can decrease greatly.
