摘要:
钾是茶叶生长过程中必不可少的营养元素,研究其空间变异规律可为茶园的养分施用与经营管理提供理论指导,为切实提高茶叶质量和产量提供建议。论文以江、浙优质茶叶种植区内的速效钾含量为研究对象,运用描述统计学分析、半方差函数模型以及空间插值方法分析钾元素在不同地域条件下的空间变异特征及其影响因素。研究结果表明:(1)天目湖和溪龙乡种植区的速效钾含量平均值明显高于龙井村和东山镇种植区,其中溪龙乡最高,东山镇最低。(2)半方差函数模型拟合显示江苏两个茶叶种植区速效钾含量有中等空间相关性,浙江两个茶叶种植区速效钾含量空间相关性较弱。(3)插值结果显示江苏省两个茶叶种植区的速效钾含量高值区均在西南和东北部,浙江省两个种植区的速效钾含量高值区分布较分散。(4)四个种植区的速效钾分布均受到结构性因素和随机性因素共同作用,浙江省两个茶叶种植区受随机性因素影响更大。
Abstract:
Potassium is a necessary nutrient element for the growth of tea. It is necessary to make comparison of tea gardens on its spatial variation for guidance to fertilization,management of tea gardens and improvements of tea's quality and productivity. In this paper,available potassium contents at some known tea planting places in Jiangsu and Zhejiang provinces were studied. Through descriptive statistics,semi-variogram model and spatial interpolation methods,the spatial variation and influencing factors of available potassium were analyzed. Results showed that:(1)The average contents of available potassium in Tianmuhu and Xilong were much higher than that in Longjing and Dongshan. The average content in Xilong was the highest,while those in Dongshan was the lowest.(2)The fitting results of semi-variogram model indicated that the spatial correlation for available potassium content of the two planting areas in Jiangsu province was medium and that of the two planting areas in Zhejiang province was weak.(3)According to the interpolation plot,it found that areas with high potassium content appeared to the southwestern and northeastern Jiangsu province,while in Zhejiang province the high value areas were disperse.(4)The spatial distribution of available potassium of four planting areas were all affected by structural factors and random factors,and that in Zhejiang province were affected more by random factors.
