Problems solved by technology

[0003] At present, planting mangrove plants in the coastal intertidal zone mostly adopts equal row spacing (such as figure 1 As shown), when the mangrove plants grow to a certain extent, the gaps between the rows are relatively narrowed, which is not conducive to making full use of sunlight, and is also not conducive to the receding of sea water. Therefore, the method of planting with equal row spacing is not conducive to the successful overwintering of mangrove seedlings at the seedling stage On the other hand, the distance between the roots of this planting method is relatively long, and the water on the surface evaporates quickly, which is not conducive to maintaining effective fresh water and increasing the salinity of the root water.

Embodiment 1

[0021] Such as figure 2 As shown, the mangrove plant 1 is planted in alternating wide and narrow rows, and the row directions of the wide and narrow rows are all perpendicular to the coastline, forming a continuous and repeated planting area of ​​narrow row-wide row-narrow row-wide row . Wherein, the narrow row spacing is 1m, the wide row spacing is twice the narrow row spacing, and the ridges are formed on the narrow rows. The width of the ridge 2 is 1.5m, and the height is 15cm.

[0022] Adopt the planting method described in this embodiment to carry out test planting in Hengshan Village, Kangxiling Town, Qinzhou City (autonomous region-level mangrove nature reserve) at the beginning of 2015, with an area of ​​300m 2 , assuming that the control group (conventional equal row spacing (row spacing is 1m) planting method) has an area of ​​150m 2 , test result shows, the mangrove root system density of planting by the mode described in this embodiment improves 15% (statistic i...

Embodiment 2

[0024] The mangrove plant 1 is planted in alternating wide and narrow rows, and the rows of the wide and narrow rows are both perpendicular to the coastline, forming a continuously repeated planting area of ​​narrow rows-wide rows-narrow rows-wide rows. Among them, the narrow row spacing is 1.5m, and the wide row spacing is twice that of the narrow row spacing. Ridges are formed on the narrow rows. The width of the ridge 2 is 2.25m and the height is 25cm.

[0025] Adopt the planting method described in this embodiment to carry out test planting in Hengshan Village, Kangxiling Town, Qinzhou City (autonomous region-level mangrove nature reserve) at the beginning of 2015, with an area of ​​300m 2 , assuming that the control group (conventional equal row spacing (row spacing is 1m) planting method) has an area of ​​100m 2 , test result shows, the mangrove root system density of planting by the mode described in this embodiment improves 12% (statistic in December, 2016, warm winter...

Embodiment 3

[0027] The mangrove plant 1 is planted in alternating wide and narrow rows, and the rows of the wide and narrow rows are both perpendicular to the coastline, forming a continuously repeated planting area of ​​narrow rows-wide rows-narrow rows-wide rows. Among them, the narrow row spacing is 1.3m, the wide row spacing is twice the narrow row spacing, and the ridges are formed on the narrow rows. The width of the ridge 2 is 1.9m, and the height is 20cm.

[0028] Adopt the planting method described in this embodiment to carry out test planting in Hengshan Village, Kangxiling Town, Qinzhou City (autonomous region-level mangrove nature reserve) at the beginning of 2015, with an area of ​​300m 2 , assuming that the control group (conventional equal row spacing (row spacing is 0.8m) planting method) has an area of ​​100m 2 , the test results show that the mangrove root density planted in the manner described in this example increases by 20% (statistics in December, 2016, warm winter ...

Abstract

The invention discloses a wide-narrow-row ridge planting method for a mangrove forest. The method specifically comprises the following steps that an alternately planting method of a wide row and a narrow row is adopted, and the row directions of the wide rows and the narrow rows are vertical to a shoreline, wherein the row spacing of the wide row is 1.5-3 times of the row spacing of the narrow row, ridging is carried out on the narrow rows, and the width of the ridge culture is equal to or slightly larger than the row spacing of the narrow rows. The mangrove forest can be planted by adopting the method provided by the invention, the surface water can be prevented from evaporating too quickly, and the surface temperature can be improved, so that the survival rate of the mangrove forest canbe effectively improved.

Description

technical field [0001] The invention relates to a method for planting mangroves, in particular to a method for planting mangroves in wide and narrow rows. Background technique [0002] Mangroves are unique plant communities on saline-alkali tidal flats in bays and estuaries at the junction of tropical and subtropical land and sea. They are an important type of vegetation to maintain the ecological balance of the coast. "Guardian of the Coast". However, land reclamation, reclamation and cultivation, and sewage discharge have destroyed a large number of mangroves, resulting in a sharp shrinkage of the area. These areas often suffer heavy losses in typhoons and tsunamis. Therefore, it is of great significance to effectively plant and restore mangroves for ecological berms in the coastal intertidal zone. [0003] At present, planting mangrove plants in the coastal intertidal zone mostly adopts equal row spacing (such as figure 1 As shown), when the mangrove plants grow to a c...
