摘要:

为考察叶面喷施含改性聚天门冬氨酸水溶肥料提高农作物产量和改善农产品品质的效果,以番茄为试验对象,开展了田间小区试验。试验共设4个处理,叶面分别喷施清水(CK)、含改性聚天门冬氨酸水溶肥料(T1)、大量元素水溶肥料(T2)、50%含改性聚天门冬氨酸水溶肥料+50%大量元素水溶肥料(T3),每个处理重复3次。结果表明:与T2处理相比,T1处理的番茄植株茎粗显著增加23.04%;T1处理的番茄果实中可溶性糖、可溶性蛋白、番茄红素含量以及糖酸比等指标,分别比T2处理的提升11.68%、20.41%、16.30%和29.29%;与T2处理相比,T1处理的番茄产量显著提高5.15%。叶面喷施含改性聚天门冬氨酸水溶肥料能显著提升番茄的产量及果实品质。

Abstract:

In order to investigate the effect of foliar spraying with water-soluble fertilizer containing modified polyaspartic acid on improving crop yield and agricultural product quality, a field plot experiment is conducted on tomato. Four treatments are set up in the experiment, and the leaves are sprayed with clean water (CK), water-soluble fertilizer containing modified polyaspartic acid (T1), large element water-soluble fertilizer (T2), 50% water-soluble fertilizer containing modified polyaspartic acid+50% large element water-soluble fertilizer (T3), respectively, and each treatment is repeated for three times. The results show that compared with T2 treatment, T1 treatment significantly increased tomato stem diameter by 23.04%. The soluble sugar, soluble protein, lycopene content, and sugar acid ratio of tomatoes treated with T1 increased by 11.68%, 20.41%, 16.30% and 29.29% compared to those treated with T2, respectively. Compared with T2 treatment, T1 treatment significantly increased tomato yield by 5.15%. Spraying water-soluble fertilizer containing modified polyaspartic acid on the leaves can significantly improve the yield and fruit quality of tomatoes.
