复合氨基酸肥料不同施用方式对茄子生长的影响

摘要： 以茄子（Solanum melongena L.）为材料,研究了复合氨基酸肥料不同施用方式（喷施、冲施、喷施+冲施）对植株净光合速率、农艺性状和矿质元素含量（总氮、总磷、总钾、总镁、总硫）的影响。结果表明,复合氨基酸肥料的施用对茄子净光合速率无正向影响;施用复合氨基酸肥料各处理地上部鲜重和单果重明显增加,但各施用复合氨基酸肥料处理间无显著差异;复合氨基酸肥料的不同施用方式影响了茄子植株总氮、总磷、总钾和总硫的含量和分布。各不同施用方式间肥效比较表明,喷施+冲施氨基酸肥料的肥效最好。

Abstract: The effects of different application methods （spraying, watering, spraying and watering） of compound amino acid fertilizer on net photosynthetic rate, agronomic index and element content （total N, total P, total K, total Mg, total S） on eggplant（Solanum melongena L.） were studied. The results showed that there was no positive effect on net photo synthetic rate of eggplant by applying compound amino acid fertilizer; The fresh weight on the grond and weight of single fruit increased by application of compound amino acid fertilizer, and there was no significant difference among the ways of applying compound amino acid fertilizer; The different application methods of the compound amino acid fertilizers affected the content and distribution of total N and total P, total K and total S. In summary, spraying and watering compound amino acid fertilizer has the best promotion effect to the growth of eggplants.

Key words: compound amino acid fertilizer, eggplant（Solanum melongena L.）, growth, net photosynthesis rate, content of mineral elements
