Embodiment three: the selection of plant under severe solonchak condition
(1) seed salt tolerant germination test
Experimentation: will eat Suaeda salsa and okra, glasswort, salt tolerant red bean, Atriplex triangularis four kinds of salt-enduring cultivars, and carry out salt tolerant comparative trial under lab simulation condition, observes the fluffy tolerance to salinity of alkali and sensitivity.Concrete operations are: indoor configuration NaCl solution, and concentration is respectively 0g/L, 3g/L, 6g/L, 9g/L, 12g/L, 15g/L, 18g/L, 21g/L, 24g/L, 27g/L, 30g/L, amount to 11 concentration gradients, adopt culture dish to carry out germination test.Continuous Observation 10 days, the germination of statistics five kinds of kinds, calculates germination rate, germination index and germination vigor.
Experimental result: the germination rate Changing Pattern of these five kinds of halophytess all shows as the rising along with NaCl concentration of salt solution, germination rate declines, and often all meet certain linear relation y=kx+b between Plants and salting liquid, k is slope, also the Sensitivity Index that Different Crop changes salinity is represented, b is intercept, represent the clear water emergence rate of different halophytes, also represent the vigor of different plant variety, Analysis of variance all reaches significance level (P < 0.01).
Table 1: five kinds of kind germination vigor tables
Different halophytes is different to the Sensitivity Index of salt dynamics, and wherein okra is the most responsive to salt dynamics, and salinity often raises 1g/L, will decline 3.3%, and the germination rate of salt tolerant red bean and glasswort declines 2.6% and 2.0%; Atriplex triangularis and the fluffy sensitive to salinity of alkali are not strong, and the downward trend of germination rate is 1.0% and 1.7%, and this also shows, different halophytess exists obvious difference to the tolerance of salinity.Contrast clear water emergence rate can be found out, the situation of emerging of five kinds of halophytess there are differences, and with 40% for indication index, Atriplex triangularis does not reach index of emerging, and all the other four kinds of halophytess meet the state of emerging.Thus, can find out, different halophytess, there is significant difference in emergence rate within 10 days observation phases.
Comprehensive comparison, from the situation of emerging with to the sensitivity of salinity, alkali is fluffy is all better than other four kinds of salt-tolerant plants, can plant on heavy salt affected soil.In order to verify indoor culture experiment result further, the fluffy plantation field comparison test of alkali arranged in south and north Sinkiang, Xinjiang.
(2) the fluffy field planting Experimental Comparison of alkali
South and north Sinkiang, Xinjiang saline-alkali soil resource-profiled: North SinKiang is to the east of west, and South Sinkiang is eastern by west, and salt accumulation in soil degree all presents the trend of aggravation, salination arable land about 1/3 is distributed in North SinKiang, and about 2/3 is distributed in South Sinkiang; Salt in the soil of North SinKiang based on sulphate or chloride-sulfate, along with alkalinization; Salt in the soil of South Sinkiang is based on chloride or sulphate-chloride.
Agricultural Climatic characteristics: genus temperate zone, North SinKiang arid half-desert-desert climate; Genus warm temperate zone, South Sinkiang extreme drought desert climate.
Table 2: heat condition table
| Year samming (DEG C) | Frost-free season (d) | Sunshine (h) | > 10 DEG C of accumulated temperature | Aridity | |
| North SinKiang | 2.5-8.0 | 140-180 | 2700 | 3100-3600 | 3-8 |
| South Sinkiang | 10-12 | 180-220 | 2700-3200 | >4000 | 8-40 |
Table 3: precipitation condition table
Water quality characteristic: river suspended material (silt): North SinKiang 0.1-0.5kg/m
3, South Sinkiang is 1-5kg/m
3; River salinity: North SinKiang is 0.05-0.5g/L, South Sinkiang 0.5-1.0g/L.
(3) field emergence comparative trial
Experimental scheme: fluffy at soil salt 31.2g/kg (South Sinkiang), 31.9g/kg (North SinKiang) grown on soil alkali, process 1 does not adopt field management measure, only carries out drilling; Process 2 and process 3 are respectively the field management measure into adopting the present invention to propose, the fluffy and glasswort of plantation alkali, the biomass that contrast alkali is fluffy and take salt ability.
Test is implemented: each process community is 160m
2, in triplicate, planting patterns drilling, line-spacing 50cm.
Sample collection: for ensureing the representativeness of soil sample sample, by before experimental scheme community difference prior to seeding (April), results (October), gathers 0-30cm soil sample.Sampling point is selected plant in the ranks, and each community is according to after the sampling of " five-spot " diagonal, and identical depth selection is mixed into a sample.Before results, Plant samples collection is carried out to Suaeda salsa, glasswort, every community random acquisition area is 1m × 1m.Plant sample completes 30min at 105 DEG C, dries for 80 DEG C and measures dry weights in order to measure biomass, then by sample comminution.Total salt content coarse ash represents, moves salt amount=crude ash content × biomass.Seed, assimilation branch and the ash content test of stem stalk adopt GB GB/T6438-2007.The dry slag method of soil total salt content measures.
Conclusion: mid-June has experimental field carried out the investigation of survival rate to both halophytess in south and north Sinkiang respectively, two kinds of halophytes survival rates are planted all more than 50% in South Sinkiang, and the halophytes survival rate of North SinKiang plantation is less than 50%, the survival rate of halophytes in South Sinkiang is apparently higher than North SinKiang; From two Plants, no matter in South Sinkiang or North SinKiang, Suaeda salsa survival rate is obviously higher than extra large covering, and Suaeda salsa survival rate is 72%, and glasswort survival rate is up to 60%, illustrates to plant on saline-alkali soil Suaeda salsa is preferably.
(4) biomass and move salt characteristic
As edible vegetable, biomass shows that more greatly its economic worth is higher, the biomass of contrast south and north Sinkiang, Xinjiang plantation Suaeda salsa and glasswort two kinds of halophytic vegetables crops, in table 4, can find out, the biomass of Suaeda salsa is significantly higher than glasswort (P < 0.01), shows to consider from economic worth angle, and Suaeda salsa is also more suitable for carrying out artificial planting.
Meanwhile, biological yield is higher, and in its plant corpus, salt content is also more, and therefore its biology moves salt benefit and is also significantly higher than glasswort.
Table 4: two kinds of halophytes biologies move salt amount and compare
As can be seen from Table 4, two kinds of halophytes biomasss of planting in South Sinkiang, Xinjiang are apparently higher than North SinKiang, and Suaeda salsa exceeds 47%, and extra large covering exceeds 51%.
Table 5: two kinds of halophytess are on the impact of soil salt balance situation
Before not planting halophytes April, soil 0-30cm initial salt content, South Sinkiang is 22.2g/kg, North SinKiang is 40.23g/kg, declined to some extent by soil salt after plantation halophytes, wherein after South Sinkiang plantation Suaeda salsa, soil salt declines 10.4%, and glasswort declines 13.9%, has more 6.3 and 9.8 percentage points than bare area.After North SinKiang plantation Suaeda salsa, soil salt declines 20.2%, and glasswort declines 19.5%, has more 14.9 and 14.2 percentage points than bare area.Table 5 result shows, relative to the bare area without vegetative coverage, plantation Suaeda salsa and salicornia europaeal obviously can promote the decline of surface soil salinity.Simultaneously, after North SinKiang plantation halophytes, soil salt fall is apparently higher than South Sinkiang, soil initial total salt content in North SinKiang is higher than South Sinkiang, and the ability absorbing salinity two kinds, the North SinKiang halophytes that salinity is heavier is higher than the relatively light South Sinkiang of soil salt content; Also difference is there is in addition between two kinds of halophytess, its salinity fall of soil of planting glasswort in South Sinkiang is higher than Suaeda salsa, and North SinKiang plantation glasswort after soil salt fall outline lower than the soil of planting Suaeda salsa, can infer the change along with salt content according to this result, the ability of two kinds of halophytess to soil absorption salinity also changes to some extent.
(5) change of alkali fluffy front and back soil alkaline index is planted
The total salt of soil, total basicity, sodium adsorption ratio and basicity four saline and alkaline indexs after the edible Suaeda salsa of south and north Sinkiang, Xinjiang plantation are investigated, result is as table 6, show: the edible Suaeda salsa of plantation significantly can reduce above four saline and alkaline indexs, can significantly reduce alkalization of soils degree, increase soil fertility.
Table 6: the situation of change of plantation alkali fluffy front and back soil alkaline index
Conclusion: can find out according to above interpretation of result and can absorb salinity in soil south and north Sinkiang, Xinjiang plantation halophytes, reach and reduce the object that upper soll layer salinity improves soil structure, successful, but there is the difference of the factors such as weather, water resource, soil salt type due to south and north Sinkiang, Xinjiang, make this two Plants all there are some differences in the ability of soil salt absorption and self raw growth after the plantation of south and north Sinkiang.Consider glasswort and alkali is fluffy to soil improvement action and using value, adopt the implantation methods of edible Suaeda salsa provided by the invention under severe solonchak condition, while selecting Suaeda salsa to carry out the improvement of soil, also can carry out artificial planting as vegetable crop, the efficiency utilization of saline-alkali soil can be realized.Thus show to adopt the present invention to eat Suaeda salsa by establishing in large scale on saliferous soil, make it wider to the suitability of salt concentration, tolerance soil salt reaches 30g/kg, the alkali of simultaneously planting is fluffy can be eaten as fresh and tender vegetables, add the income of peasant, the salt content in soil can be reduced, the edible efficient plantation of Suaeda salsa and the doulbe-sides' victory of Improvement of Ecological Environment under realizing strongly salined soil condition simultaneously.
Above-described embodiment is only for example of the present invention is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And apparent change extended thus or variation are still among protection scope of the present invention.
