The Research And Analysis Of Facilities Vegetable Soil NPK In Fugou County

In this study,the effects of fertilization management on the vegetable land use in Fugou area were investigated,and the contents of total nitrogen,total phosphorus,total potassium and available potassium were collected and analyzed at different levels.In comparison with the nutrient content of soil layers,the soil samples collected by the wheat fields in the soil were used as the control.The relationship between the soil nutrient content and the soil nutrient content in the soil and the application of fertilizer in different soil layers were analyzed by combining the results of test and the amount of fertilization and the cultivation period.It provides a reference for the accurate,scientific and reasonable fertilization formula in the management of vegetable and water in the irrigation and drainage area,and also provides the theoretical basis and basic data for the healthy,stable and sustainable development of the vegetable industry in the area.The main conclusions are as follows:1.Fugou area facilities vegetable land soil nitrogen content level is not high,generally in and below the level of three.From the detection results,the nitrogen content in the whole soil profile exhibits regularity diminishes with depth,gradually decreasing the amplitude of weak.There were 0-20 cm and 20-40 cm in 3/4 and 5/6 soil samples was lower than that of control,but in the 3/4 40-60 cm soil layer was higher than that of the control samples.2.The content of phosphorus in the vegetable soil was high,and the content range and mean value were 0.372-4.350 g / kg and 1.410 g / kg.The phosphorus content of each soil sample was higher than that of the control.In the section,from 0-20 cm to 20-40 cm soil layer between the slight decline in the trend,20-40 cm to 40-60 cm between the significant decline,and showed increased with the cultivation of the increase in the law.3.The content of total potassium in vegetable soil was lower than that in other areas of China.The total potassium content of the vast majority of samples was at the fifth level,and the individual samples were at the six level,and there was no significant difference compared with the control The Soil total potassium content in the profile did not show a significant increase or decrease in the law.The content of available potassium in the soil was significantly different from that of total potassium,and the content range and mean of available potassium were 0.067-6.464 g / kg and 1.762 g / kg respectively.There were only two survey sites in 40-60 cm soil Below the first level,the remaining K content of all samples is far higher than the standard.In the profile showed a significant trend with the soil to reduce the trend,combined with the survey point of view with the increase in the number of years to increase the law.4.According to the survey data of soil samples in Fugou area and the investigation of sampling points,there should be excessive application of phosphorus and potassium in the fertilizer and water management of vegetable vegetables.In the future production it is recommended to reduce the application of phosphate fertilizer and potassium fertilizer.While maintaining the organic fertilizer and fertilizer mixed application mode,but also to remove the effect of organic fertilizer application of the "superstition" thinking,appropriate to reduce the amount of organic fertilizer application.5.The extensiveiy management of the facilities、vegetables、fertilizer、and water in Fugou area,The lack of detailed records,showing a certain degree of blindness and randomness.The reason is,Fugou area long-term facilities for vegetable cultivation,but mostly "self-taught",farmers lack of systematic,scientific guidance and training.To solve this problem requires all levels of government,scientific research institutions and colleges and universities to improve the guidance of professionals and training,and enrich the farmers to obtain facilities and management techniques and other aspects of information and channels.
