黄河中游吕梁段大枣裂果原因及应对措施

Cause and Tactics of Jujube Fruit Cracking on Lvliang Eection of Yellow River

针对大枣在成熟期遇雨普遍发生裂果现象,该文从大枣裂果发生的原因及机制入手,全面分析了成熟期间果实结构、组织水势、矿质营养与植物生长调节物质的变化特点,提出了双向化调技术在大枣果实避灾及抗裂果试验中的实施方案,并对利用无性繁殖及转基因技术培育大枣避灾及抗裂果新品种的可能性作了分析,旨在为吕梁及沿黄地区枣林田间栽培与管理、选种与种植及枣业发展提供科学依据。

Jujube in the mature fruit cracking occurs is a common phenomenon during the encounter rain,is a physical process of mechanical fracture. This article from the jujube fruit cracking the causes and mochanism,a comprehensive analysis of the fruit during ripening fruit structure,organizational potential,mineral nutrition and plant growth regulators changes, we proposed a two-way transfer of technology in disaster prevention and anti-jujube fruit cracking test the feasibility of plans, while asexual reproduction ,or jujube cultivation of transgenic technology for disaster prevention and the possibility of new varieties of fruit cracking was evaluated. Aimed at the Luliang and Yellow River Basin area jujube forest field cultivation,management, seed selection and planting and jujube industry to provide a scientific basis.
