高尔夫草坪病虫害研究进展

为了让避雨设施栽培进一步在杧果生产上应用，以3 a生的‘热农1号’杧果为试材，研究了避雨对杧果两性花率、果实生长发育、产量和采后耐贮性的影响。结果表明：避雨栽培下杧果平均两性花率为35.9%，显著高于对照；花穗寒害率为42.7%，比对照降低24.6%；果实平均增产75.7%，显著高于对照，且果实采后烂果率和病情指数得到有效控制；果实大小和单果质量略有降低，最终座果率、内在品质均与对照无显著差异。避雨设施栽培在南方多雨产区具有一定的应用和推广价值。

Research Advances on Diseases and Insect Pests of Golf Turfgrasses

This research is to provide theoretical guidance for the widely used in the production of mango rain cover cultivation. The experimental materials, Mangifera indica L. 'Renong 1', were put under two different cultivation conditions: rain shelter and open field. The results showed that the bisexual flower rate under rain shelter was 35.9% , significantly higher than the control, and cold injury rate was 42.7%, decreased by 24.6%. The size and single fruit weight decreased slightly under rain shelter and the growth was not affected, meanwhile both the final fruitset and internal quality were not affected negatively. In comparison with open field, the mean yield of mango in rain cover increased by 75.7%, and the fruit decay and disease index of mango fruit after harvest were significantly reduced. These data suggest that the rain cover cultivation have higher values of application and popularization in coastal rainy region of South China.
