Effect Of Soil Properties Of Caragana Compost And Amendments On Cucumber Cropping

On account of such problems as serious cropping obstacle for soil and high-degree alkalization of facilities soil in Ningxia province, this essay takes cropping cucumbers with 10 years of continuous cropping soil as the research object, mainly furfural residue and vinegar bad raw material production as complex organic acid soil conditioner, and mainly sheep dung and caragana korshinskii composting of raw materials, using pot and field experiments, and a total of three test are made, Experimen 1:not adding modifier as CK, deployment of eight processing modifier component and acidity value design, system research different modifier component and acidity condition, salt ions, microbial quantity of soil nutrients and plant growth condition, the influence of screening conditioner suitable acidity and components; Experiment 2:ot adding modifier as CK, design different seven processing modifiers, system research applying different modifier content, saltions, microbial quantity of soil nutrients and plant growth condition, the influence of screening to determine the conditioner as best content; Experimen 3:CK, with traditional chicken manure as fertilizer conditioner, to make caragana and korshinskii compost two-factor experiments, different amount of nitrogen to replace survive composting system and modifying agent applied to soil nutrient, soil en2yme activity and microorganism quantity and the influence of plant growth, clear korshinskii optimal amount of nitrogen replacement and survive the compost and the best combination of modifier, the above three test results will provide the facilities cucumber to provide theoretical basis for the sustainable use of soil, the results are as follows:I.A Complex organic acidic soil conditioner test showed that the effect of different acidity of continuous cropping cucumber soil improvement:1.Different acidity and amendment application components significantly reduce the continuous cropping soil’s pH·and the provinces of EC, the reduced effects are significant as acidity becomes lower;2.The application of modifier can significantly increase the soil’s total nitrogen, available nitrogen, available potassium and organic matter, including ameliorators pH of 3,2and 1 the increase of total nitrogen is most significantly, without the use of dilute sulphuric acid acid available nitrogen and available potassium content is the highest, pH for.3 times;3.Relative to CK, provinces and acidity of components amendment significantly increased soil’s Na+, K+, Cl-, not acid conditioner Na+, K+, SO42", HCO3- has the highest cumulative effect, with the decreasing acidity of Na+,K+,SO42-,Cl- significantly reduced, pH of 2 modifier reduces the most significant, Harvest period pH of 2 reduce the most significantly;4.The amendment added significantly increased bacterial count in provinces, reduced the number of actinomycetes, with the decreasing acidity of actinomyces and fungi number increases, the highest pH for phase 3 Harvest period bacteria and actinomycetes, pH of 1 Harvest period highest fungi;5.Added modifiers significantly promote plant growth, with the decreasing acidity, it was reduced after the first increased trend, the modifiers with pH value 3 and 2 has the most significant effect of promotion, modifier with pH value 2 has the most significant effect of increasing production; the modifier with pH value 1 increased plant height, but reduced the thick stems;6.The non-additive vinegar significantly improved fruit soluble sugar and nitrate content, reduced the content of Vc. The soluble sugar, soluble acid and soluble solids were increased after the first reduce trend with the decreasing acidity, the content soluble solids and soluble acid with PH value 3 are higher;7.The comprehensive analysis showed that the pH equal to 2 will promote plant growth, fruit yield, reduce soil salt accumulation and have the most significant effect to increase soil fertility. II. he compound organic acid soil conditioner test showed that the effect of different dosage of continuous cropping cucumber soil improvement:1.With the increase the pH and EC significantly reduced, applying modifier content, total nitrogen, organic matter increased with the increase of modifier addition,1300,1600 kg/666.7 m2 increased the most significant effect, conditioner fertilization significantly increased available n content, the most significant effect of 1600 kg/666.7 m2;2.The modifiers with different amounts had no significant effect on K+,600kg/666.7 m2,Cl-,Ca2+,Na+,K+,SO42- had the lowest accumulated content,1600kg/666.7 m2 Na+,K+, accumulation of HCO3- serious, provinces 800kg/666.7 m2,Cl-,Ca2+,Na+,K+minimum cumulative content, cause K+,Mg2+1600kg/666.7 m2 magnesium accumulation;3.The improver bacteria and actinomycetes with 6O0,800kg/666.7 m2 increased significantly;4.With increasing of plant growth, applying modifier content of 1600kg/666.7 m2 plant height, stem diameter, the highest chlorophyll content; Modifier used to promote the growth of the cucumber root,600,1000kg/666.7 m2, the total root length, root volume increasing effect is remarkable,1600kg/666.7 m2 root weaker;5.The comprehensive analysis showed that 600,800kg/666.7 m2 significantly improve soil salt accumulation, promote plant growth, root development, considering the cost at the same time,600kg/666.7 m2 seems the best. III. the study on caragana korshinskii composting with ingredients to the soil of continuous cropping cucumber repair mechanism showed that1.Amendment and caragana korshinskii compost application can effectively reduce the continuous cropping soil pH at the same time, increase the soil EC, and the traditional chicken manure 75%nitrogen korshinskii compost and conditioner treatment the most significant the pH.EC, the most significant growth;2.In terms of soil nutrient and soil enzyme activity, the treatment on modifier and caragana korshinskii composting is superior to the treatment on single korshinskii compost,and the traditional chicken manure 50%nitrogen korshinskii compost and amendment of total nitrogen, available nitrogen and available potassium content is significantly better than other treatments, and has a better performance in terms of soil enzyme activity;3.The amendment and caragana korshinskii compost treatment microbial numbers of single use korshinskii compost treatment, and the traditional chicken manure 50%nitrogen korshinskii compost and amendment number of bacteria, fungi and actinomycetes were significantly higher than other treatment;4.The amendment and caragana korshinskii compost treatment were not significant changes of plant height and stem diameter, and the traditional chicken manure were 75%,50%nitrogen korshinskii compost and conditioner treatment significantly increased the chlorophyll content, and 75%with traditional chicken manure nitrogen korshinskii compost treatment the highest cucumber yield, other treatment because of the CK;5.The adding of improver had no significant effect on cucumbers’and, caragana korshinskii compost reduced along with the amount of nitrogen replacement, cucumber and soluble sugar, Vc and the increasing trend of soluble solids, soluble acid and nitrate is on the decline;6.The comprehensive analysis shows that the traditional chicken manure 50%nitrogen korshinskii compost and amendment is the most significant improvement on soil quality, and improve fruit quality.
