Effect Of Aquasorb And Organic Carbon Fertilizer On Soil And Plant Growth

Currently in some regions of China, the soil texture is becoming compact, soil fertility is declining, and plant growth is limited. It’s due to the unreasonable application methods and consumption in the practical application of aquasorb. In order to study the optimum dosage of aquasorb and organic carbon fertilizer, this paper selected four 1-year-old nursery-grown plants of Chinese pine, Fraxinus chinensis, Syringa oblata lindl, Swida alba Opiz and two herbaceous plants of Festuca elata and Medicago sativa as the research objects. Take the aquasorb and organic carbon fertilizer application method and consumption as the main variable factors.This study is divided into two parts. The first part is the use of aquasorb alone. Four 1-year-old nursery-grown plants were using the following five dosage of aquasorb,5 grams,10 grams,20 grams, 30 grams and 50 grams per paint. Two herbaceous plants were using the following five dosage of aquasorb,50 grams,80 grams,100 grams,150 grams and 200 grams per square meter. The other part of study is the mixed application of aquasorb and organic carbon fertilizer. Aquasorb consumption of 10 grams,20 grams and 30 grams per paint mixed with organic carbon fertilizer consumption of 5 grams, 10 grams and 20 grams per paint respectively for four 1-year-old nursery-grown plants. Aquasorb consumption of 80 grams,100 grams and 150 grams per square meter mixed with organic carbon fertilizer consumption of 100 grams,150 grams and 200 grams per square meter respectively for two herbaceous plants. Principal component analysis was used to analyze the growth status and soil fertility status of the plant under different dosage of aquasorb and organic carbon fertilizer treatment. The conclusion is the best application method and dosage of each plant.The results show:The best application method and dosage of 1-year-old Chinese pine and Swida alba Opiz is mixed 10 grams aquasorb with 10 grams organic carbon fertilizer per plant. The best application effect of Fraxinus chinensis and Syringa oblata lindl are single aquasorb dosage of 10 grams and 20 grams per plant respectively. The best application effect of Festuca elata and Medicago sativa is mixed 100 grams aquasorb with 150 grams organic carbon fertilizer per square meter. The results of the best application method and dosage of six kinds of plants will provide a more scientific and reasonable basis for cultivation of high quality nursery-grown plants and herbaceous plants in water resources shortage in arid and semiarid areas.
