摘要
对西湖龙井茶一级产区土壤和肥料管理状况的调查表明,基肥的施肥时间和方式较为科学合理,为西湖龙井茶的优异品质提供了基本保障。不同村的施肥习惯和肥培管理有明显差异,但同村有较高的一致性。调查茶园平均肥料投入群体1041.13元/亩,龙井43茶园1281.00元/亩,肥料投入达到每亩800元时,加大肥料投入对春茶产量和产值增加贡献不大,控制施肥对促进西湖龙井茶一级产区节本增效具有重要意义。66.7%茶园中的有机质含量达到优质茶园土壤标准,全氮、速效磷、速效钾、速效硫、速效锌基本达到或超过优质茶园土壤标准;55.6%茶园速效镁含量偏少,建议适当增施镁肥。根据调研结果分析了该地区茶园肥培管理中存在的问题,并提出了解决建议。
The investigation based on soil and fertilizer management status in the first-level reserve of West Lake Longjing tea base showed that the time and way of basal fertilization guaranteed for the excellent quality of the West Lake Longjing tea. There are different fertilization practice and fertilizing management way among the villages, but a high level of consistency in a village. Fertilizer investment in tea garden of seedling population surveyed was 1041.13 yuan/ mu, and investment of Longjing 43 was 1281.00 yuan / mu. When the fertilizer investment reached 800 yuan per mu, increasing fertilizer inputs contributed little to production and output value of spring tea. Controling fertilizer rate was significance for promoting premier production region of West Lake Longjing tea to be low-cost and more benefit. In 66.7% of the tea gardens, the soil organic matter content achieved the standard of the high quality tea garden soil, and total nitrogen, available phosphorus, available potassium, available sulfur, available zinc almost reached or exceeded the standard of the high quality tea garden soil. 55.6% of tea gardens were suggested to improve the amount of magnesium fertilizer, which were lack of available magnesium content. According to the investigation results, we analyzed the existing problems and provided solutions on fertilizer management.
