Abstract

The invention discloses a kind of methods for improving East China coastal saline soil fertility using seashore paspalum, are related to heavy salinized ground ecological management field.This method is：Using salt tolerant turfgrass, seashore paspalum is selected to carry out the efficient quick improvement of beach saline land；1. saline-alkali soil arranges；2. plant salt tolerant turf；3. maintenance management.The present invention has following advantages and good effect：1. select the seashore paspalum of salt tolerant can efficient quick improvement salt-soda soil；2. sodding turf than relatively low rainy season in soil salt content, vegetation can be established rapidly, inhibits soil water evaporation, and control soil salt rises, with achieving the purpose that soil alkaline；The salt tolerant herbaceous plant of acquisition is screened for many years 3. the seashore paspalum selected is laboratory, suitable for the ecological recovery in salt-soda soil, is particularly useful to the stabilization of saline field ecosystem.

Description

Improve the method for East China coastal saline soil fertility using seashore paspalum

Technical field

The present invention relates to strand heavy salinized ground ecological management fields more particularly to a kind of utilization seashore paspalum to improve East China The method of coastal saline soil fertility.

Background technology

China possesses all kinds of using 5.5 hundred million mu of saline alkali land resource, and heavy salinized 33,700,000 mu of ground is the largest standby Cultivated land resource.Domestic alkaline land improving Application way and technology be summed up approximately as：It is 1. physically improved；2. water conservancy improves； 3. chemical modifying；4. biological modification.

In the measures of improvement saline-alkali soil, renovation dynamics, salt discharge effect from salt-soda soil and scope is promoted the use of It sees, in a variety of alkaline land improving technical methods, utilizing works Drainage of salt is an important hydrotechnics measure, only strong Full pumping equipment, other measures can just play one's part to the full.But in the restriction of water resource at this stage, environmental degradation aggravation and life Under the conditions of producing cost raising, great change will occur for the improvement pattern that the past consumes excessively merely by water resource.

The content of the invention

The purpose of the present invention be that overcome East China strand heavy salinized ground salt content is high, soil texture is poor, crop cannot Grow, improve the of high cost and time it is long the problem of, provide a kind of improves East China coastal saline soil fertility using seashore paspalum Method.

The object of the present invention is achieved like this：

Using salt tolerant turfgrass, seashore paspalum is selected to carry out the efficient quick improvement of beach saline land.

Specifically, this method comprises the following steps：

1. saline-alkali soil arranges；

2. plant salt tolerant turf；

3. maintenance management.

Working mechanism：

Seashore paspalum can not only beautify the environment, and purify air, adjust miniclimate, reduce noise, conserve water and soil and prevent disaster Deng, and exposed table soil can be effectively covered within a short period of time, moisture-salt transport is hindered, reduces ground moisture evaporation, reduces table The salt content of layer soil.Seashore paspalum tolerance to cold is poor, is suitable only for East China Southern Shandong Province, Jiangsu and District of Shanghai, improves Coastal saline-alkali soil fertility.

The present invention has following advantages and good effect：

1. select the seashore paspalum of salt tolerant can efficient quick improvement salt-soda soil；

2. sodding turf than relatively low rainy season in soil salt content, vegetation can be established rapidly, inhibit soil water evaporation, control Soil salt rises, with achieving the purpose that soil alkaline；

The salt tolerant herbaceous plant of acquisition is screened for many years 3. the seashore paspalum selected is laboratory, it is extensive suitable for the ecology in salt-soda soil It is multiple, it is particularly useful to the stabilization of saline field ecosystem.

Description of the drawings

Fig. 1 is this method flow chart of steps.

In figure：

1-saline-alkali soil arranges；

2-plant salt tolerant turf；

3-maintenance management.

Specific embodiment

It is described in detail with reference to the accompanying drawings and examples：

This method：

1. saline-alkali soil arranges -1

It is sticked when for heavy salinized wet, hard when doing, ventilation, permeable bad feature, per acre using 10-15 cubes of organic fertilizer, Including barnyard manure, compost and peat, deep plough 10-30 centimetres；Prepartion of land is paid attention to during site preparation and fertilization, pine table soil is ploughed, is flattened with roller bearing, Make its consolidation, must be filled and led up at hollow, otherwise ponding, Bermuda grass can be caused dead, and be unfavorable for trimming；

2. plant salt tolerant turf -2

The 6-8 months are rainy season, and soil salt content reduces, and is the optimum season for sodding salt tolerant seashore paspalum turf heavy salinizedly；It will Turf is cut into the divot of 30-50cm × 30-100cm, and band soil 1.0-2.0cm should not be blocked up, so as not to it is too heavy, when sodding also not It is convenient；When sodding turf, turf seam crossing should be made not stay distance, turf seam crossing is filled out with fine earth；500-1000kg is used on careless face The roller of left and right weight presses and scrapes, and makes careless face equal with surrounding soil face, and such turf touches with soil；

3. maintenance management -3

It should all fully water before being laid with turf and after sodding；According to salt-soda soil nutrient situation and Turfgrass Growth needs, really Determine nitrogen phosphoris and potassium fertilizer ratio, compounding application trace element carries out rational application of fertilizers, N：P：K=1：2：2；Overwintering water is poured before facing frost, in advance Anti- spring arid stabilizes ground temperature, enhances the cold tolerance of turfgrass；The accumulation of salt in the surface soil phase in spring sprinkles profoundly water, and inhibits the accumulation of salt in the surface soil.
