摘要
为探究秋冬茬沙培番茄施加含有低温弱光诱抗功能的氨基酸水溶肥对其生长及产量的影响,试验共设置5个处理,即CK0不施加肥料,只浇灌清水;CK常规施肥;T_(1)低浓度;T_(2)中浓度;T_(3)高浓度。在番茄生长的3个阶段进行施加,测定番茄各项指标。结果显示,随着水溶肥浓度的提高,番茄的生长趋于旺盛,T_(2)处理番茄较T_(1)相比维生素C、可溶性糖、可滴定酸、糖酸比分别高出了7.74%、2.77%、14.71%、20.50%。T_(2)、T_(3)处理番茄叶片胞间CO_(2) 浓度与CK相比大幅度降低,T_(2)处理的最大光合能力提高了50%,T_(2)处理产量最高,说明稀释1600倍可以促进设施番茄产量的提高。综上所述,秋冬季节种植设施番茄使用氨基酸水溶肥可将肥料稀释1600倍,既能提高作物养分含量,保证番茄光合作用正常运转,增加产量。
In order to investigate the effect of applying amino acid water-soluble fertilizer containing low temperature and low light induced resistance on the growth and yield of autumn and winter stubble sandcultivated tomato,the experiment was set up with five treatments,including CK0 without fertilizer,CK conventional fertilizer,T_(1) low concentration,T_(2) medium concentration,and T_(3) high concentration.Fertilization was applied at three stages of tomato growth,and tomato indexes were determined.The results showed that as the concentration of water-soluble fertilizer increased,the growth trend of tomato was vigorous,and the vitamin C,soluble sugar,titratable acid,and sugar-acid ratio of T_(2) treatment were 7.74%,2.77%,14.71%,and 20.50%higher,respectively,compared with T_(1).The concentration of inter-cellular CO_(2) of tomato leaves in T_(2) and T_(3) treatments was substantially reduced compared with that of CK,and the maximal light and capacity of T_(2) treatment was increased by 50%,and T_(2) treatment had the highest yield,indicating that dilution of 1600 times could promote the improvement of facility tomato yield.In conclusion,the use of amino acid water-soluble fertilizer in tomato planting facilities in autumn and winter seasons can be diluted 1600 times,which can not only improve the nutrient content of the crop,but also ensure the normal operation of tomato photosynthesis and increase the yield.
