吐鲁番地区无核白葡萄叶片养分含量研究

Nutrient Contents in the Leaves of Vitis vinifera cv.Thompson Seedless in Turpan

在吐鲁番地区选择具有代表性的粘土、壤土、沙土无核白葡萄园6块试验地,采集葡萄叶片,测定了氮、磷、钾、硼、钙、镁等6种元素含量。结果表明,吐鲁番地区3种土质葡萄叶片氮(33.277、34.547g·kg-1和38.511g·kg-1)、钙(13.875、14.144g·kg-1和14.477g·kg-1)、镁(2.854、3.128g·kg-1和3.490g·kg-1)的含量在处于适宜值范围。磷在粘土、壤土质地葡萄叶片含量是3.096g·kg-1、3.309g·kg-1处于适宜值范围,在沙土质地葡萄叶片含量是4.77g·kg-1稍微偏高。钾在3种土质含量是15.955、15.134g·kg-1和18.536g·kg-1高于适宜值范围。微量元素硼在3种土质含量是0.114、0.14g·kg-1和0.113g·kg-1低于适宜值范围。

Six plots with typical local soils （clay, loam and sandy） were selected by Vitis vinifera cv. Thompson Seedless was cultivated in Turpan. Leaves were collected and the contents of the elements were measured, such as N, P, K, B, Ca, and Mg. The contents of the elements in the leaves of Thompson Seedless cultivated three types of the soils mentioned above were N （33. 277, 34. 547 g·kg^-1 and 38. 511 g·kg^-1）, Ca （13. 875, 14. 144g·kg^-1 and 14.477 g·kg^-1）, and Mg （2. 854, 3. 128g· kg^-1 and 3,490g· kg^-1）, respectively,which ranked at appropriate ranges. The contents of P in clay and loamy soils were 3. 096 g·kg^-1 and 3. 309 g·kg^-1, also in reasonable ranges, while in sandy soil, it was 4.77 g·kg^-1, a little bit high. The contents of K were 15. 955, 15. 134 g·kg^-1 and 18. 536 g·kg^-1 , respectively, higher than appropriate range. The contents of B were 0. 114 g·kg^-1, 0.14 g·kg^-1 and 0. 113 g·kg^-1 , respectively, less than appropriate range.
