为给莎车扁桃的优质丰产提供施肥需求的科学依据,通过测定分析莎车县19个乡镇102个扁桃花样的5种常量元素(N、P、K、Ca、Mg)和5种微量元素(B、Zn、Fe、Mn、Cu)的质量浓度,确定新疆莎车县扁桃花营养元素标准值范围。结果表明:N、P、K、Ca、Mg、B、Mn等7种元素的取值遵从正态分布,而Zn、Fe、Cu取值近似正态分布;采用4点5分段的概率分级法,使1~5级分别对应花营养元素质量浓度标准值中的缺乏、低值、正常值、高值、过高5个数值范围,各级出现的花样概率分别为10%、20%、40%、20%和10%,花分析值在(X-0.524 6 S)~(X+0.524 6 S)间可作为标准值中的正常值范围,这与通过高产水平果园花的分析值非常接近;扁桃花中矿质元素质量浓度标准值的正常值范围为:N 27.72~30.04 g/kg、P 3.57~4.06 g/kg、K 23.18~26.11 g/kg、Ca 8.62~10.39 g/kg、Mg 13.95~15.17 g/kg、B 64.43~78.07 mg/kg、Zn 61.43~70.38 mg/kg、Fe 231.01~243.30 mg/kg、Mn 38.34~45.09 mg/kg和Cu 12.81~14.53 mg/kg。
In order to provide the scientific basis for fertilizing the good yield of Shache Almond, 102 almond plants (N, P, K, Ca, Mg) and 5 trace elements B, Zn, Fe, Mn and Cu) were determined to determine the range of standard values of nutrients in almonds of Shache County of Xinjiang. The results show that the values of N, P, K, Ca, Mg, B, Mn and other seven elements follow the normal distribution while the values of Zn, Fe and Cu approximate the normal distribution; Law, so that 1-5 levels correspond to the lack of standard value of nutrient concentration, low value, normal value, high value, high value range of 5, the probability of pattern appears at all levels were 10%, 20% 40%, 20% and 10%, respectively, and the flower analysis value can be used as the normal range of the standard values from (X-0.524 6 S) to (X + 0.524 6 S) The normal values ranged from N 27.72-30.04 g / kg, P 3.57-4.06 g / kg, K 23.18-26.11 g / kg, Ca 8.62-10.39 g / kg, Mg 13.95 to 15.17 g / kg, B 64.43 to 78.07 mg / kg, Zn 61.43 to 70.38 mg / kg, Fe 231.01 to 243.30 mg / kg, Mn 38.34 to 45.09 mg / kg and Cu 12.81 to 14.53 mg / kg.
