| 摘 要： | 莴苣盆栽试验表明,氨基酸厂废水在适宜浓度下,可以提高蔬菜的鲜嫩度和维生素C、可溶性糖的含量,并使全氯和硝酸盐的含量限定在卫生标准之内;同时又不会使土壤原有性质产生破坏。废水在紫色土上的最适浓度为1:80(废水与清水体积比,下同),但它在作物生长前期表现为毒害作用与低浓度促进作用并存,且以毒害作用为主,直到后期才表现出营养肥效作用。

| Abstract: | The pot-tests with lettuce indicated that if the waste water disposed from the Amino Acid Factory had been used correctly, it could increase Vitamin C, soluble sugar, fresh and tender degree of the vegetable, while Cl and NO_3 ion concentration could be centroled under the food heathly standard. The results also showed that intrinsic properties ef soils could be retained. These tests could determine the optimum concentration of the waste water as 1:80 by the soil-plant system. It also proved that the roles of the waste water in the soil-plant system were toxity and low concentration-dependent stimulation(mainly the former)during the initial growth period of vegetable but nutrition during the later period. |
