不同酸性有机肥浸提液对棉花生长及土壤性质的影响
Effects of Different Acidic Extracts of Organic Fertilizers on Cotton Growth and Soft Properties
摘要
Abstract
[Objective] Organic fertilizer has the effect of improving soil properties and improving soil fertility,but it was inconvenient for large-scale fertilization.Xinjiang drip irrigation technology has been perfected,but the proportion of organic fertilizer application was rather lower.In this study,organic fertilizer will be extracted with inorganic acid,organic fertilizer extract combined with drip irrigation in Xinjiang to explore its effect on soil properties and cotton growth.[Method] The organic fertilizer was extracted with phosphoric acid and nitric acid with pH 1,3 and 7 (water),and the extraction time was 2 days,and then they were applied to the potted cotton.[Result]The results showed that:(1) Both the nitric acid and its extracts of organic fertilizer reduced the pH of the soil,and the same pH of phosphoric acid and phosphoric acid organic fertilizer extract treatments were greater than nitric acid and nitric acid organic fertilizer extract treatments.(2) The soil organic matter,total nitrogen,available phosphorus and available potassium in the phosphate organic fertilizer extract treatments whose pH was 1 and 3 were higher than that of the same pH treatments of nitric acid organic fertilizer extract.The soil nutrient in the treatments of the application of acidic organic fertilizer extract was higher than that of the application of the same pH of acid.(3) Nitric acid and nitric acid leach extract treatments increased the plant height and plant dry matter of cotton,but the dry matter accumulation of phosphate extract treatment was higher than that of nitrate extract treatment.[Conclusion] In conclusion,the application of nitric acid and phosphoric acid organic fertilizer extract improved soil nutrients content and promoted the growth of cotton.pH 1 phosphate fertilizer extract had the best effects.关键词
