Economical seashore saline soil greening quick planting method

Abstract

The invention provides an economical seashore saline soil greening quick planting method. The method includes the following steps that (1) main water spray ditches with the width of 50 cm and the depth of 80 cm are dug in determined land used for greening in the transverse direction every 20 m; (2) a main water spray blind ditch is dug downwards in the center of the bottom of each main water spray ditch, wherein an upper opening of the main water spray blind ditch is 30 cm wide, a lower opening of the main water spray blind ditch is 20 cm wide, and the main water spray blind ditch is 30 cm deep; (3) the main water spray blind ditches are filled with niter, and natural soil is retuned into the main water spray ditches; (4) branch water spray ditches are dug intersecting with the dug main water spray ditches by 90 degrees every 2 m, an upper opening of each branch water spray ditch is 50 cm wide and each branch water spray ditch is 60 cm deep; (5) a branch water spray blind ditch is dug downwards in the bottom of each branch water spray ditch, wherein an upper opening of the branch water spray blind ditch is 20 cm wide, a lower opening of the branch water spray blind ditch is 15 cm wide and the branch water spray blind ditch is 20 cm deep; (6) the branch water spray blind ditches are filled with niter, and natural soil is retuned into the branch water spray ditches; (7) saline soil conditioners are laid on the surface layers of greenbelts, and the saline soil conditioners are uniformly mixed with soil below the surface layers. The method has the effects of achieving quick desalination, saving cost and improving the saline soil improvement effect.

Description

technical field [0001] The invention belongs to the field of saline-alkali land transformation, and in particular relates to an economical greening rapid planting method in seaside saline soil. Background technique [0002] With the implementation of my country's coastal development strategy, several economic and technological development zones and Binhai New Areas have been established in coastal areas, which have become the locomotive of my country's economic construction. However, these newly developed coastal new urban areas have brought certain difficulties to the construction of a green ecological environment due to their proximity to the coast. Coastal saline soil greening has always been a problem that has plagued gardeners. [0003] Most of the traditional saline-alkali land improvement technologies rely on the foreign soil method, that is, replacing the local saline-alkali soil with good cultivated soil from other places. As the area of ​​development in our countr...

Problems solved by technology

In recent years, there have been more and more reports on improving the soil without changing the soil, but most of them need to groove the green space as a whole, dig underground water blind ditch to fill the pebble drench layer, and at the same time use large water to irrigate salt. On the one hand, the cost is too high. The improvement fee is about 80 yuan. On the other hand, a lot of fresh water resources are wasted, which is not conducive to the friendly development of the environment.
