土壤盐渍化和盐渍危害土壤肥力和作物生产,尤其是在干旱地区。为了解决这个问题,使用生物炭与石膏结合,石灰,农家肥是改善盐害土壤的有前途的解决方案。在大麻实验中,棉棒生物炭(BC)以20吨/公顷的比例与石膏(G)结合使用,石灰(L),和农场粪便(F)的比率为5吨/公顷和10吨/公顷。这些被表示为BCG-5、BCL-5、BCF-5、BCG-10、BCL-10和BCF-10。实验使用了三种不同类型的土壤,其电导率(EC)与钠吸附比(SAR)之比为2.45:13.7、9.45:22和11.56:40。BCG-10的应用导致水稻生物量的显着改善,叶绿素含量,和整体增长。据观察,在EC:SAR(2.45:13.7)中,将BCG-10应用于土壤使膜稳定性指数增加了75%,EC:SAR(9.45:22)中的97%,与各自的对照治疗相比,EC:SAR(11.56:40)为40%。使用BCG-10后,树叶中的过氧化氢下降了29%,23%,欧共体:SAR(2.45:13.7)为21%,欧共体:SAR(9.45:22),和EC:SAR(11.56:40)土壤,相对于他们的控制,分别。BCG-10的应用导致甘氨酸甜菜碱在EC:SAR(2.45:13.7)中增加60、119和165%,欧共体:SAR(9.45:22),和EC:SAR(11.56:40)土壤。欧共体:SAR(2.45:13.7),欧共体:SAR(9.45:22),EC:SAR(11.56:40)土壤在BCG-10施用处理中的抗坏血酸含量均增加了70、109和130%。本试验结果表明,BCG-10在不同程度的盐胁迫下对水稻植株生长和生理性状的增强作用最大。这是通过降低过氧化氢水平来实现的,使植物细胞更稳定,和增加非酶活性。
Soil salinization and sodication harm soil fertility and crop production, especially in dry regions. To combat this, using biochar combined with gypsum, lime, and farm manure is a promising solution for improving salt-affected soils. In a pot experiment, cotton stick biochar (BC) was applied at a rate of 20 t/ha in combination with gypsum (G), lime (L), and farm manure (F) at rates of 5 and 10 t/ha. These were denoted as BCG-5, BCL-5, BCF-5, BCG-10, BCL-10, and BCF-10. Three different types of soils with electrical conductivity (
EC) to sodium adsorption ratio (SAR) ratios of 2.45:13.7, 9.45:22, and 11.56:40 were used for experimentation. The application of BCG-10 led to significant improvements in rice biomass, chlorophyll content, and overall growth. It was observed that applying BCG-10 to soils increased the membrane stability index by 75% in EC:SAR (2.45:13.7), 97% in EC:SAR (9.45:22), and 40% in EC:SAR (11.56:40) compared to respective control treatments. After BCG-10 was applied, the hydrogen peroxide in leaves dropped by 29%, 23%, and 21% in EC:SAR (2.45:13.7), EC:SAR (9.45:22), and EC:SAR (11.56:40) soils, relative to their controls, respectively. The application of BCG-10 resulted in glycine betaine increases of 60, 119, and 165% in
EC: SAR (2.45:13.7),
EC: SAR (9.45:22), and
EC: SAR (11.56:40) soils.
EC: SAR (2.45:13.7),
EC: SAR (9.45:22), and
EC: SAR (11.56:40) soils all had 70, 109, and 130% more ascorbic acid in BCG-10 applied treatment, respectively. The results of this experiment show that BCG-10 increased the growth and physiological traits of rice plants were exposed to different levels of salt stress. This was achieved by lowering hydrogen peroxide levels, making plant cells more stable, and increasing non-enzymatic activity.
