摘要:
为探明淹水对不同水肥管理竹叶花椒幼苗渗透调节物质含量的影响,揭示不同水肥管理竹叶花椒的耐涝适应机制。以竹叶花椒为试验材料,采用土壤水分(包括:0%、40%、60%和80%田间持水量(FWC))、氮肥(包括:0、75、150和300 kg N/hm2)、磷肥(包括:0、30、60和120 kg P2O5/hm2)和钾肥(包括:0、75、150和300 kg K2O/hm2)四因素四水平正交设计试验,通过水肥处理盆栽90 d后测定持续淹水0 d、1 d、3 d、5 d植株叶片质膜透性、渗透物质含量和外观表型,及排水后的恢复情况,并用隶属函数法对各水肥处理后植株耐涝性进行综合评价。在淹水过程中,T12(N300P30K0+60%FWC)处理植株叶片受害程度最轻,耐涝性最强,T8(N300P60K75+40%FWC)、T9(N0P60K300+60%FWC)、T10(N75P120K150+60%FWC)、T11(N150P0K75+60%FWC)和T12(N300P30K0+60%FWC)处理排水后期可恢复正常生长,而其余处理植株均死亡。淹水期间,各水肥耦合竹叶花椒质膜透性和脯氨酸含量均表现为上升趋势;可溶性糖和可溶性蛋白含量均呈现出先上升后下降的趋势,在第3 d达到最大值。通过综合隶属函数法估算出在60.8%WFC、243 kg N/hm2、97 kg P2O5/hm2、243 kg K2O/hm2水肥管理条件下植株可获得较强的耐涝性。因此适宜的土壤水分和N、P、K配施对促进竹叶花椒幼苗生长和抗逆性提高具有重要作用。
Abstract:
This study aimed to explore the impact of flooding stress on osmotic adjustment substance contents and waterlogging resistance acclimation mechanism of Zanthoxylum armatum under coupling of water and fertilizer management. A pot experiment with the soil moisture (including 20%, 40%, 60%, 80% field water capacity (FWC)), nitrogen (including 0, 75, 150 and 300 kg N/hm2), phosphorous (including 0, 30, 60, 120 kg P2O5/hm2) and potassium (including 0, 75, 150 and 300 kg K2O/hm2) fertilizer four factors and four levels orthogonal design was conducted to study the leaf membrane permeability, osmotic material content and appearance of phenotypic during waterlogging 0 d, 1 d, 3 d and 5 d, and plant recovery after drainage. The subordinate function was applied to comprehensively evaluate the impact of water and fertilizer on waterlogging resistance of seedlings. The results showed that the T12 (N300P30K0 + 60%FWC) treatment had the least damage of leaves and the highest ability of waterlogging resistance under waterlogging condition. After drainage, the seedlings of T8 (N300P60K75 + 40%FWC), T9 (N0P60K300 + 60%FWC), T10 (N75P120K150 + 60%FWC), T11 (N150P0K75 + 60%FWC) and T12 (N300P30K0 + 60%FWC) treatments could recover to normal growth, while the others died. During waterlogging stress, free proline content and relative conductivity of leaves in all treatments were increased; leaf soluble sugar and soluble protein contents increased until reaching the maximum values and then declined, and the maximum values was observed in the 3rd day in all treatments. The optimal combination of water and fertilizer for improvement of waterlogging stress was 60.8%WFC, 243 kg N/hm2, 97 kg P2O5/hm2 and 243 kg K2O/hm2 by waterlogging resistance comprehensive evaluation. The results suggest that appropriate soil moisture and N, P, K fertilizer application are important for promoting growth and enhance stress resistance of Zanthoxylum armatum seedlings.
