句容葡萄园健康土壤培育措施探析

Healthy Soil Cultivation in Vineyard of Jurong

为了提高句容葡萄园土壤质量,实现葡萄产业的稳定发展。2012—2016年对句容8个葡萄园土壤进行跟踪调查,同期在每个葡萄园取不同土层土壤化验分析。结果表明:2012年0~20、20~40 cm土层土壤,有机质含量分别为1.58%和1.02%,4年后0~20 cm土层,有机质含量只有1.12%,在4年的时间,由于耕作方式不当,用肥不合理等原因,导致0~20 cm土层有机质总体上减少了1/4。土壤是农作物的生存载体,而有机质是土壤活力的核心,人类通过调节土壤有机质而影响土壤质量。句容葡萄生产要想持续稳定的发展,提高土壤有机质含量,培育健康土壤生态系统势在必行。而生草栽培、秸秆利用是健康土壤培育最有效的持续、生态方法,也是最行之有效的发展方向。

To improve the quality of vineyard soil and realize the stable development of grape industry inJurong, a tracking investigation was conducted to analyze samples of different soil layers from eight vineyardsduring 2012 to 2016. The results showed that the content of soil organic matter at 0-20 and 20-40 cm soillayer was 1.58% and 1.02% in 2012, respectively, and after four years＇ grape production, the content of soilorganic matter at 0-20 cm soil layer was only 1.12%. Improper farming methods and unreasonable fertilizationled to a quarter decrease of soil organic matter at 0-20 cm soil layer during the four years. Soil is the survivalcarrier of crops and organic matter is the core of soil activity, human beings affect soil quality by the regulationof soil organic matter. To increase soil organic matter content and improve healthy soil ecosystem are essentialto the sustainable development of grape production. The cultivation of grass and utilization of straw are bothsustainable and ecological methods for soil cultivation, which form the most effective development direction.
