摘要:
为了探究棉花在不同连作障碍消减措施下根系形态生理特征的变化,本研究采用盆栽试验,研究了添加生物炭(BF)、施用有机肥(MF)、施用硫肥(SF)和轮作(CR)四种消减措施对新疆棉花盛花期根系生理生化、生长形态以及土壤养分的影响。结果表明,不同的消减措施对棉花根系和土壤特征的影响存在差异。添加生物炭显著提高土壤pH值和62.48%的土壤速效钾含量,降低有效磷含量,并显著提高了棉花根系活力、根系长度和平均直径(P<0.05)。与对照相比,轮作增加了土壤有机质、全氮和碱解氮含量,增加程度分别为31.79%、40.28%及32.43%,降低土壤有效磷和速效钾的含量,并显著降低了根系丙二醛含量的积累(P<0.05),且根系长度、根系表面积、根长密度和比根长最大。土壤速效钾和有效磷含量在施用有机肥处理下显著增加,分别增加了53.75%、16.75%,且根系平均直径显著增加(P<0.05),这将提高根系与土壤的接触面积,有利于膜下滴灌下异质性养分的吸收。施用硫肥虽然能够有效提高棉花根系活力,但在本研究区域硫肥的施用不利于棉花根系的生长发育。综上所述,添加生物炭、施用有机肥和轮作可通过影响根系形态或生理特征来提高根系功能的发挥,有利于养分的高效利用,是该区域可持续绿色农业的有效管理措施。
Abstract:
In order to investigate the changes of morphological and physiological characteristics of cotton root under different control measures of continuous cropping obstacle, pot experiments were conducted to study the effects of four control measures, including the addition of biochar (BF), application of organic fertilizer (MF), application of sulfur fertilizer (SF) and crop rotation (CR), on the physiological and biochemical, growth patterns and soil nutrients of the roots of cotton in Xinjiang during the flowering stage. The results showed that the effects of different reduction measures on cotton root and soil characteristics were different. The addition of biochar significantly increas ed the soil available potassium by 62.48% and pH value , but decreased available phosphorus, and cotton root activity , root length and average diameter increased significantly ( P<0.05). Rotation increased the soil organic matter, total nitrogen and alkali nitrogen content, and the proportion were 31.79%, 40.28%, and 32.43% respectively. But reduced the content of available phosphorus and available potassium in the soil, and decreased the accumulation of malondialdehyde in t he roots (P<0.05). Besides, the root length (L), root surface area (A), root length density (RLD) and specific root length (SRL) had the maximal value. Application of organic fertilizer significantly increased soil available potassium and available phosphorus, and the proportion were 53.75%, 16.75% respectively. Moreover root diameter increased significantly ( P<0.05), which could increase the contact area between roots and soil, and facilitate the absorption of heterogeneous nutrients under mulched drip irrigation. In this study, although the application of sulphur fertilizer can effectively improve the root activity, it was not conducive to the growth and development of cotton root. In conclusion, adding biochar, applying organic fertilizer and rotation can improve the function of root system by affecting the root morphology or physiological characteristics, hence soil nutrients can be used efficiently by cotton. Consequently, the effective management measures for sustainable green agriculture in the study region were addition of biochar (BF), application of organic fertilizer (MF) and crop rotation (CR).
