Description
Technical field
The invention belongs to alkaline land improvement field, especially relate to the economical greening method for quickly planting of a kind of marine solonchak.
Background technology
Along with the enforcement of China coast Great developing strategy, several economic and technological development zones and Binhai New District have been set up in coastal area, have become the locomotive engine of China's economic construction., these new coastal city districts newly developed, because ground is by coastal, bring certain difficulty to afforestation improvement of the ecological environment, and marine solonchak greening is a difficult problem that is perplexing Gardener author always.
Traditional alkaline land improving technology relies on soil moved in to improve the original method mostly, with the good anthropogenic soil in strange land, replaces local saline-alkali soil.Along with the increase year by year of China's exploitation area, the farmland of destroying also will get more and more, China Shi Yige populous nation, and grain is that China people's life guarantees, and soil is the precious resources that we depend on for existence, and the method can't resolve essential problem.In recent years, the report that not soil removal and replacement is improved the soil on the spot increases, but mostly need to be to the whole fluting in greenery patches, the underground trickle french drain stranguria during pregnancy layer that rockfills that digs, adopt flood pouring to drench salt simultaneously, one side high cost, every square meter improvement takes about 80 yuan, freshwater resources are wasted in a large number on the other hand, are unfavorable for close friend's development of environment.Therefore, how at coastal region, not ruining farmland, to complete planting technique be a very urgent research direction.
Summary of the invention
The problem to be solved in the present invention be to provide a kind of can be cost-saving, improve the economical greening method for quickly planting of marine solonchak of reclamation of saline soil effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the economical greening method for quickly planting of a kind of marine solonchak, comprise the steps: 1) determining on land use for greening, at interval of 20m, laterally dig the square main trickle ditch of a wide 50cm, dark 80cm;
2) at square main trickle bottom of trench center, dig a wide 30cm suitable for reading downwards, the wide 20cm of end opening, the main trickle french drain of dark 30cm;
3) in main trickle french drain, fill clean stone nitre, original soil is also entered in square main trickle ditch;
4) and the square main trickle ditch having dug intersect 90 degree, at interval of 2m, then dig wide 50cm, square the trickle ditch of dark 60cm;
5) at square trickle bottom of trench, dig a wide 20cm suitable for reading downwards, the wide 15cm of end opening, a trickle french drain of dark 20cm;
6) in a trickle french drain, fill clean stone nitre, original soil is also entered in square trickle ditch;
7) at top layer, greenery patches paving solonchak conditioner, and mix evenly with the downward soil in top layer.
Further, step 3) in, when filling clean stone nitre in main trickle french drain, woven cloth is layered in main trickle french drain, then clean stone nitre is inserted in woven cloth, after by woven cloth, clean stone nitre being sealed, then original soil is also entered in square main trickle ditch;
Step 6) in, when filling clean stone nitre in trickle french drain, woven cloth is layered in a trickle french drain, then clean stone nitre is inserted in woven cloth, after by woven cloth, clean stone nitre being sealed, then original soil is also entered in square trickle ditch.Woven cloth can prevent that silt from infiltrating in the gap between clean stone nitre, thereby guarantees that salt discharge is smooth and easy.
Preferably, in step 7) in the thickness of solonchak conditioner be 10cm.
Preferably, in step 7) in the soil of the thick downward 50cm thickness of solonchak conditioner and top layer of 10cm is mixed evenly.
Preferably, in step 7) described in conditioner by plant crushing straw and acid stronger desulfurization cream, add acid turfy soil and form.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, the underground drainage network smoothly that is provided with in greenery patches, by the capillary osmosis of soil, after the salt in the former solonchak in greenery patches is dissolved in natural rainfall or fresh water pouring, drain into rapidly in underground trickle french drain, reach the object of soil quick desalination; The present invention is not to the whole fluting in greenery patches, but layout digs trickle french drain, main trickle ditch is different from a trickle trench depth, main trickle french drain is different from a trickle french drain degree of depth, every square meter soil melioration expense can be saved 30 yuan, not only can effective cost-saving input, and can protect large-area farmland to exempt from breaking-up; And, in the present invention, do not have stone to drench layer, cut husky hole, not only from the material aspect dropping into, saved a lot, the use labour has also reduced the labor service of beating husky hole, backfill stone pouring layer simultaneously.
