Test Example 1
147 ten of Shihezis being connected No. 98 ground 170# cottons in 2010 makes an experiment; It all is drip irrigation; Experiment and demonstration and contrast all in 4 months, drip irrigations in the last ten-days period emerge (dried broadcasting wet out); Sowing, field management is in full accord, and different is: in the experiment and demonstration zone, after planting drip earlier to row kind hole, film limit water breakthrough drenched after, according to the mu consumption saline-alkali soil conditioner of the present invention is joined to drip in the drip irrigation jar after with 1: 120 times of dilution again and executes.Soil improvement agent of the present invention is used in the test site; Clear water is only dripped in the check plot; The term of execution of test, demonstration each processing is chosen 3 representational points for investigation with diagonal process; Each point is got the investigation of 50 strains fixed point, and the main project of investigation has: seedling-growing time, seedling rate, seedling stage, florescence, bell phase, the term of opening bolls, output, quality etc.
147 ten connect ground pilot survey table No. 98
Table 1
Table 2
Table 3
Analyze according to above questionnaire summarized results, each process points cotton seedling rate of using saline-alkali soil conditioner of the present invention improves, and emerges in advance; Protecting flower bud strain number increases; All than contrast in advance, blow-of-cottons are normal, not early ageing for flower bud phase, florescence, flowering and boll-setting period; Cotton pearl produces and grows normally, and the per unit area yield that grows fine all has raising in various degree.
147 ten connect ground cotton quality synopsis No. 98
Influence to soil total salt and pH value: soil layer top layer (0-10cm) pH value of not using of using saline-alkali soil conditioner according to result of laboratory test that No. 98 ground tests of 147 ten companies are fetched earth obviously descends 0.51; 10-20cm descends 0.24; 20-30cm decline 0.08. total salt content 0-10cm top layer content obviously reduces, and 10-30cm is not obvious.
147 ten connect No. 98 ground and experimental field use modifying agent front and back soil total salt and pH value variation
Conclusion (of pressure testing): the present invention uses back cotton seedling rate and improves, and emerges in advance, protects the increase of flower bud strain number, and all than contrast in advance, blow-of-cottons are normal for flower bud phase, florescence, flowering and boll-setting period, not early ageing, and cotton pearl produces and grows normally, and the per unit area yield that grows fine all has raising in various degree.PH value and total salt content obviously reduce.
Test Example 2
For a short time turning No. 3 cotton fields in farm in the Kelamayi in 2011 makes an experiment; It all is drip irrigation; Experiment and demonstration and contrast all in 4 months, drip irrigations in the last ten-days period emerge (dried broadcasting wet out); Sowing, field management is in full accord, and different is: in the experiment and demonstration zone, after planting drip earlier to row kind hole, film limit water breakthrough drenched after, according to the mu consumption saline-alkali soil conditioner of the present invention is joined to drip in the drip irrigation jar after with 1: 120 times of dilution again and executes.Soil improvement agent of the present invention is used in the test site; Clear water is only dripped in the check plot; The term of execution of test, demonstration each processing is chosen 3 representational points for investigation with diagonal process; Each point is got the investigation of 50 strains fixed point, and the main project of investigation has: seedling-growing time, seedling rate, seedling stage, florescence, bell phase, the term of opening bolls, output, quality etc.
Total salt assay of table 1 and pH value are measured
By the analysis of table 1 detected result: the total salt component 0.903%, 0.905%, 0.904% that in every mu of saltings, drips respectively before total salt component of executing saline-alkali soil conditioner 2.5kg of the present invention, 2kg, 1kg is used respectively reduces to 0.370%, 0.401%, 0.417%.PH value reduces to 7.98,8.12,8.10 by using preceding 8.23,8.34,8.31.
Table 2 output of cotton is identified summary sheet
Analyze by table 2 output of cotton qualification result: in every mu of saltings, drip the cotton raising the output of executing saline-alkali soil conditioner 2.5kg of the present invention, 2kg, 1kg respectively and improved 42.7%, 32.2%, 21.6%.
Table 3 Economic and Efficiency Analysis table
By table 3 Economic and Efficiency Analysis: in every mu of saltings, drip respectively and execute saline-alkali soil conditioner 2.5kg of the present invention, 2kg, 1kg, income has increased by 890.1 yuan, 742.8 yuan, 509.8 yuan.
Test Example 3
2011 in the Manas County cotton field on Xin Hu farm makes an experiment; During irrigation before seeding, saline-alkali soil conditioner of the present invention by every mu of 1.5-2 kilogram, is supplied examination to add by different effective levels and converts 1: 100 times of water dilution in the common sprayer; Evenly be sprayed on soil surface, pour water then.For the second time seedling stage with product by different effective levels from water inlet drips, application with irrigation water.
1. to handling the influence of soil salt: drop to 0.38% by 0.91% before the test, descended 63%.
2. to the influence of output of cotton: handling average unginned cotton per unit area yield has increased by 40.31 kilograms, and yield per unit of lint has increased by 14.15 kilograms, and effect of increasing production very significantly.
3. cotton being emerged to keep a full stand of seedings has certain promoter action, to the influence of quality, the average increment of fiber yield rate 0.83%
Conclusion (of pressure testing): saline-alkali soil conditioner of the present invention can not only reduce the pH value of soil, can also reduce the saltiness of soil, the growth of farm crop preferably.After saline-alkali soil conditioner of the present invention is handled, can fall alkali and fall salt, remove salinity rapidly to the Toxicity in Crops effect; The activating soil nutritive ingredient is improved the living environment of plant in soil.
What should explain at last is: obviously, the foregoing description only be for clearly the present invention is described and is done for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among protection scope of the present invention.
