AI Technical Summary

Technical Problem

Existing drought-resistant oat cultivation techniques neglect the multiple secondary stresses of "respiration-heat-oxidation" in the grain microenvironment during the grain-filling stage and the imbalance of antioxidant distribution among organs, resulting in the failure to fully realize yield potential.

Method used

Microcapsule suspensions containing cerium dioxide nanozymes, L-cysteine, and glume-specific colonizing yeasts were sprayed onto the ear, combined with treatment solutions of α-ketoglutarate and surfactants, micro-irrigation and intermittent mild air blowing, and spraying with a mixed solution of sodium selenite and proline to optimize the glume microenvironment and grain metabolic flow.

Benefits of technology

It created an adjustable "intelligent micro-reaction chamber" that improved the gas exchange efficiency of oat hulls, enhanced the metabolic flow of flag leaf assimilate output and ear rachis reception, activated the antioxidant enzyme system inside the grain, and improved grain filling efficiency, grain plumpness and yield.

Abstract

本发明涉及作物栽培技术领域,具体涉及一种提高抗旱性的燕麦栽培方法。该方法包括:S1:抽穗后向穗部喷施含纳米酶、L‑半胱氨酸及颖壳特异酵母的缓释微胶囊,预先改善微环境;S2:灌浆初期分时分区喷施含α‑酮戊二酸与表面活性素的旗叶处理液、以及含钼酸铵与甜菜碱的穗部处理液,协同强化源库代谢流;S3:灌浆盛期于午后进行微量灌溉并随即对穗层温和吹风,创设“呼吸窗口期”以优化籽粒气体交换与散热;S4:在上述操作后喷施亚硒酸钠与脯氨酸混合液,系统诱导籽粒内源抗氧化网络。有效破解干旱下燕麦灌浆期颖壳导致的次生胁迫,显著提升水分利用效率与籽粒产量。
