摘要
有机废物可以有效地回收以生产有机改良剂,例如堆肥,用于作物生产,从而通过有效的废物管理减少影响。本试验旨在研究城市垃圾堆肥与禽畜粪便复合处理对温室盆栽番茄植株生长、硝酸盐还原酶(NR)活性和重金属(HM)吸收与分布的影响。从城市垃圾中获得的两种堆肥(C1 = 3:2和C2 = 2:3)与禽粪混合,在两个不同的日龄(105 d和173 d)和两种混合率(32.5 g pot - 1和65 g pot - 1)下使用;以不加堆肥改良剂的土壤为对照。本试验以盆栽番茄植株为试验材料,在植株移栽65 d后测定植株生长和养分吸收情况。结果表明,堆肥类型和堆肥率影响生物量产量。然而,堆肥年龄对植物的发育没有影响。并结合氮素循环研究了番茄植株的营养状况。随着堆肥用量的增加,叶片亚硝酸盐积累量增加。NO2−的积累与NR活性的显著增加有关。随着堆肥的使用,叶片中HM含量降低。HM优先在根系和叶片中积累,土壤向根系的金属迁移顺序为:Fe (1.08 ~ 2.14)> Co (0.53 ~ 4.10)>Cu (0.28 ~ 2.28) >Mn (0.3 ~ 1.34) >Zn (0.87 ~ 1.21)>Cr(0.12 ~ 1.64)。动态生物积累因子(BAFdyn)在根和茎中分别最高和最低。根系对Cd和Pb起屏障作用。综上所述,堆肥的使用对番茄植株有益,特别是在混合料中使用较多的禽粪(C2)所获得的堆肥。
Municipal Waste and Poultry Manure Compost Affect Biomass Production, Nitrate Reductase Activity and Heavy Metals in Tomato Plants
Abstract Organic wastes can be usefully recovered to produce organic amendments, for example, compost, to be used for crop production, thus reducing impacts through efficient waste management. The aim of this work was to study the effects of compost obtained from municipal waste in combination with poultry manure on plant growth, nitrate reductase (NR) activity and absorption and distribution of heavy metals (HM) in plant tissues of tomatoes, grown in pots in greenhouses. Two compost types obtained from municipal waste mixed with poultry manure (C1 = 3:2 and C2 = 2:3) were used at two different ages (105 d and 173 d) and at two mix rates with soil (32.5 g pot−1 and 65 g pot−1); soil with no compost amendment was used as control. The experiment was conducted using tomato plants in pots and plant growth and nutrient plant uptake was determined after 65 days from plant transplanting. Results obtained indicated that compost type and compost rate affected biomass production. However, compost age did not influence the development of plants. Nutrient status of tomato plants was also investigated with reference to the N cycle. Nitrite accumulation in the leaves increased with the increase in compost doses. The accumulation of NO2− was associated with a significant increase in NR activity. HM content in leaves decreased with compost use. HM accumulated preferentially in roots and leaves and the soil to root metals transfer was in this order: Fe (1.08–2.14)> Co (0.53–4.10)>Cu (0.28–2.28) >Mn (0.3–1.34) >Zn (0.87–1.21)>Cr (0.12–1.64). The highest and lowest dynamic bioaccumulation factors (BAFdyn) were observed in roots and stems, respectively. The root system acted as a barrier for Cd and Pb. It was concluded that compost use is beneficial for tomato plants, with particular reference to the compost obtained by using a higher amount of poultry manure (C2) in the mix.
