摘要
以‘micro tom’番茄为试材,采用盆栽控制的方法,每次设置300、450 mL·盆-12个灌水量,分别记为W300、W450,4个不同的施氮水平0 g·kg^(-1)(N0)、0.08 g·kg^(-1)(N1)、0.16 g·kg^(-1)(N2)、0.32 g·kg^(-1)(N3),开展2个生育时期试验,研究了水氮互作对盆栽番茄叶片叶绿素含量、生长发育动态、产量和品质的影响,以期得到番茄生长阶段同化产物的动态分布规律,为番茄生产合理的水氮运筹提供参考依据。结果表明:番茄生长发育符合“Logistic”曲线,在2个季度的试验中,最高产量均出现在W450N2处理下,分别达到195.24、201.23 g,比其他处理高出1.62%~50.47%、1.91%~52.69%。合理的水氮管理可以长时间维持地上部分干物质的最大积累速率,最终提高番茄的产量。
Taking tomato‘micro tom’as the experimental material,a pot controlled experimental method was adopted.Two irrigation amounts of 300 and 450 mL·pot-1(N0)were set each time,denoted as W300 and W450,with four different nitrogen application levels of 0 g·kg^(-1)(N0),0.08 g·kg^(-1)(N1),0.16 g·kg^(-1)(N2),and 0.32 g·kg^(-1)(N3).Two growth stage experiments were conducted.The chlorophyll content,growth and development dynamics,yield,and quality of potted tomato leaves were used as research indicators,in order to obtain the dynamic distribution pattern of assimilates during tomato growth stage and provide reference for rational water and nitrogen management in tomato production.The results showed that the growth and development of tomatoes followed a logistic curve.In the two quarters of the experiment,the highest yield occurred under the W450N2 treatment,reaching 195.24 g and 201.23 g,respectively,which were 1.62%-50.47%and 1.91%-52.69%higher than other treatments.Reasonable water and nitrogen management can maintain the maximum accumulation rate of above-ground dry matter for a long time,ultimately improving tomato yield.
