“根引”腐殖酸水溶肥对设施番茄生长及产量性状的影响

Effect of ‘Genyin'Humic Acid Water- soluble Fertilizer on Protected Tomato's Growth and Yield Characters

【目的】研究＂根引＂腐殖酸水溶肥对设施番茄生长和产量性状的影响,确定＂根引＂在设施番茄上的最佳施加量。【方法】通过土壤起垄栽培,在设施番茄上施加1、1.5和2 kg/667m2＂根引＂共3次,定期测定番茄的生长特性及产量性状。【结果】施加1和1.5 kg/667m2的＂根引＂对番茄生长促进效果较明显,而1.5和2 kg/667m2的＂根引＂对番茄的后期产量促进效果较明显,但二者之间的差异不显著。【结论】施加1-2 kg/667m2的＂根引＂腐殖酸水溶肥促进了番茄的生长,并增加了番茄的单果重以及产量,施加1.5-2.0 kg/667m2的＂根引＂,对番茄生长促进和产量及单果重的增加效果较明显。

【Objective】The experiment is carried out to research the effects of ‘Genyin＇humic acid water- soluble fertilizer on protected tomato growth and yield characters and determine the optimal adding amount of ‘Genyin＇for protected tomato.【Method】Through soil ridging cultivation,applying 1 kg /667m2,1. 5 kg /667m2,2 kg / 667m2,a total of 3 times ‘Genyin＇on protected tomato,growth and yield characters of tomato were measured regularly. 【Result 】1 kg /667 m2 and 1. 5 kg / 667m2‘Genyin＇obviously promoted tomato growth,while 1. 5 kg /667m2 and 2 kg / 667m2‘Genyin＇affected tomato yield obviously,but the difference between the two treatments was not significant.【Conclusion】1- 2 kg /667m2 of ‘Genyin＇humic acid water-soluble fertilizer promoted the growth and increased the fruit weight and yield of tomato,overall,1. 5- 2. 0 kg /667m2 of ‘Genyin＇was the optimal amount for tomato growth and the yield and the single fruit weight.
