本文调查了温度对香蕉第三最幼叶片、第三最幼叶片中脉和第七最幼叶片叶柄的干物质中N、P、K、Ca、Mg、Na、Mn、Cu、Zn和Cl的含量影响.香蕉品种为wiliams,种植于利用太阳光照、环境条件控制的、室内昼/夜温度为17/10、21/14、25/18、29/22、33/26或37/30℃的盆栽房里,时间为12周.温度对大多数组织中的所有养份的含量影响显著(P=0.05).在一定温度范围内,某些养分含量保持稳定.例如,在第三叶片中,在17～37℃温度范围内,N的含量稳定;在21～29℃温度范围内,K的含量稳定.样品的养分含量与整个植株的养分含量的比值随温度的变化而变化.这个比值用来确定是否该样品能反映整个植株的养分状况.比值变化的大小取决于元素本身.对于元素Zn,比值变化最小;对于元素Ca、MG和Mn,比值变化大(2～3倍):对于元素N、P、K、Na、Cu和Cl,则比值变化介于中间状态.试验表明,对生长在不同气候条件下香蕉叶片分析数据的解释时,必须加倍小心,尤其对于元素Ca Mg和Mn 可靠的诊断可在日温度为17～30℃之间获得.
This paper investigated the effects of temperature on the contents of N, P, K, Ca, Mg, Na, Mn, Cu, Zn and Cl in the dry matter of the third youngest leaf, the third youngest leaf midrib and the seventh youngest leaf blade The banana cultivars were wiliams grown in pots under daylight / night temperatures of 17/10, 21/14, 25/18, 29/22, 33/26 or 37/30 ° C controlled by sunlight and environmental conditions Room, for a period of 12 weeks Temperature had a significant effect on the content of all nutrients in most tissues (P = 0.05) Certain nutrient contents remained stable over a range of temperatures For example, in the third leaf at The content of N is stable in the temperature range of 17-37 ° C, and the content of K is stable in the temperature range of 21-29 ° C. The ratio of the nutrient content of the sample to the nutrient content of the whole plant varies with the temperature, and this ratio is used Determine whether the sample can reflect the nutrient status of the whole plant.The ratio of the change depends on the element itself.For the element Zn, the change of the ratio is the smallest.For the elements Ca, MG and Mn, the ratio changes greatly (2 ~ 3 times): for the element N , P, K, Na, Cu and Cl, the ratio between the changes in the middle state.Experiment showed that the growth of different gas When the analysis and interpretation of data to be cautious under banana leaves, especially for elements of Ca Mg and Mn reliable diagnosis can be obtained between days at 17 ~ 30 ℃ temperature.
