基质对大豆芽苗菜生物学性状的影响与评价

Effects and Evaluation of Substrate on Biological Characters of Soybean Sprouts

  • 摘要: 为筛选适宜种植大豆芽苗菜的最佳基质,本研究以大豆品种中品661为材料,以草炭、蛭石、珍珠岩3种基质的单基质以及复配基质作为栽培基质,从而评价不同基质对大豆芽苗菜生物学性状的影响。结果表明:草炭基质(D2)栽培大豆芽苗菜,地上部鲜重显著高于园土(Y)栽培29.44%;可溶性蛋白含量显著高于园土(Y)栽培10.16%;脯氨酸含量显著高于园土(Y)栽培262.50%。而草炭∶蛭石∶珍珠岩=1∶1∶1(F2)基质栽培的大豆芽苗菜地上部含水量显著高于园土(Y)栽培5.47%,有利于提高芽苗菜的口感及柔嫩度。综上,草炭栽培基质(D2)是大豆芽苗菜最理想的栽培基质。

     

    Abstract: To select the optimal substrate for planting soybean sprouts and vegetables. Soybean variety Zhongpin 661 was used as experimental material, and vermiculite, peat and perlite were used as main matrix materials to evaluate the effects of different substrates on biological characteristics of sprouts. The results showed that the fresh weight of soybean sprouts and vegetables cultivated on peat substrate(D2) was significantly higher than that cultivated on garden soil(Y) by 29.44%. The soluble protein content was significantly higher than 10.16% in garden soil(Y) cultivation. The proline content was significantly higher than 262.50% in garden soil(Y) cultivation. The aboveground water content of soybean sprouts cultivated on a substrate of peat ∶ vermiculite ∶ perlite=1∶1∶1(F2) was significantly higher than that of garden soil(Y) cultivation by 5.47%, which is beneficial for improving the taste and tenderness of sprouts. In summary, peat cultivation medium(D2) is the most ideal cultivation medium for soybean sprouts and vegetables.
