Variation characteristics of different greenhouse ages on soil nutrients in facility grape
摘要
Abstract
In order to clarify the characteristics of soil fertility change and status of nutrients in greenhouse vineyards with different ages,375 soil samples with greenhouse ages of 1-5,5-10 and>10 years were collected from Raoyang County,Hebei Province.The pH,EC,organic matter,total and available contents of nitrogen,phosphorus,potassium,medium and trace element contents were examined.The results showed that in the 60-100 cm soil layer,the pH was significantly decreased and the EC was significantly increased with greenhouse age over 5 years.In the 0-20 cm soil layer,the average organic matter content with greenhouse age over 10 years was significantly increased,compared to age 1-5 years,and in the 0-20 cm soil layer mainly at a moderate level.In 0-20 cm soil layer,the contents of total nitrogen with greenhouse age over 10 years was significantly increased compared to age 1-5 years,and alkali-hydrolyzed nitrogen in 20-40 cm soil layer was significantly increased with the extension of greenhouse age.In the 60-100 cm soil layer,nitrate nitrogen increased over the greenhouse age.The contents of nitrate nitrogen in the 80-100 cm soil layer for 6-10 years and over 10 years greenhouse ages was increased by 67.2%and 87.2%,respectively,compared to 1-5 years greenhouse ages.The contents of alkali-hydrolyzed nitrogen and total nitrogen in 0-20 cm soil layer with all ages were mainly at a moderate or rich level,and nitrate nitrogen in 40-100 cm soil layer were mainly at a moderate level.The contents of available phosphorus and available potassium in the 0-100 cm soil layer and total phosphorus in the 0-40 cm soil layer with greenhouse age over 10 years were significantly increased compared to age 1-5 years.The contents of total phosphorus and available potassium for all greenhouse ages were mainly at rich level,and the total potassium and available phosphorus varied among different greenhouses.The greenhouse age had no significant effect on the exchangeable calcium,but significantly increased the exchangeable magnesium,available iron and available zinc content in the 0-20 cm soil layer.The contents of exchangeable magnesium,available iron,available copper and available zinc in 0-20 cm soil layer for all greenhouse ages were at moderate level or above.In summary,with greenhouse age increase,the soil pH was reduced,while EC value,soil organic matter,total nitrogen and phosphorus,available nitrogen,phosphorus,potassium,exchangeable magnesium,available iron,available copper and available zinc content were increased.Therefore,it was recommended to carry out scientific and reasonable nutrient management for greenhouse grape based on greenhouse age and nutrient status.关键词
