灰枣是且末县栽培面积较大的两大红枣品种之一,目前,且未且灰枣种植面积已达8 100公顷,总产量为29 659吨。灰枣采前落果是一种生理现象,枣果生长到白熟期以后,因营养不良,果实容易产生离层,造成未熟脱落现象。本文通过多年从事红枣栽培管理实践,初步研究并分析了灰枣采前落果的主要原因,制定出相应的防治措施。一、采前落果主要原因1.土壤过度干旱土壤水分状况的好坏直接影响灰枣根系吸水和叶片蒸腾,进而制约干物质积累所需要的营养元素
Jujube is one of the two Jujube cultivars with large cultivated area in Qaeda County. At present, Jujube not covered has an area of 8,100 hectares with a total output of 29,659 tons. Jujube plucking before falling fruit is a physiological phenomenon, jujube growth to white maturity, due to malnutrition, the fruit is easy to produce delamination, resulting in unripe shedding phenomenon. In this paper, jujube cultivation and management practices for many years engaged in the preliminary study and analysis of the main reasons for the jujube harvest before falling fruit, to develop the appropriate control measures. First, the main reason before the harvest of fruit 1. Soil over-drought Soil moisture status directly affect the water absorption and leaf transpiration, and thus restrict the accumulation of nutrients required for dry matter
