The Impact of Organic Fertilizer Replacement of Chemical Fertilizers on Yield and Quality of Tea Gardens in China
摘要
Abstract
In order to explore the effects of organic fertilizer replacement of chemical fertilizers on tea yield,quality,and soil physicochemical properties in China,relevant literature on organic fertilizer replacement of chemical fertilizers in tea gardens was collected both domestically and internationally. Meta analysis was used to quantitatively analyze the effects of organic fertilizer replacement of chemical fertilizers on tea yield,quality,and soil physicochemical properties in China under different organic substitution ratios,soil physicochemical properties and substitution years. The results show that compared with the application of chemical fertilizers alone,partial substitution of organic fertilizer can significantly improve tea yield,quality,and soil nutrient content in tea gardens.The organic substitution ratios,soil conditions,and substitution period are important factors that affect the effectiveness of organic substitution. When the organic substitution ratio was less than 25%,the yield increase effect was the best. When the organic substitution ratio was between 25% and 75%,the best effect was achieved in improving the quality of tea. When the organic substitution exceeded 75%,it would lead to a decrease in tea yield due to insufficient nutrient supply in the soil during the season. Organic substitution had a better effect on increasing tea yield when soil organic matter<20 g·kg-1,alkaline nitrogen<100 mg·kg-1,available phosphorus<5 mg·kg-1,and pH>4.5. When soil organic matter>20 g·kg-1,alkaline nitrogen>100 mg·kg-1,available phosphorus>20 mg·kg-1,available potassium>100 mg·kg-1,and pH<5.5,the tea quality improvement effect was better. There was a cumulative effect of organic fertilizer efficiency,and the longer the organic substitution period,the better the effect on improving tea yield and quality.关键词
