摘要: 雹災(zāi)是農(nóng)業(yè)生產(chǎn)主要災(zāi)害之一,，雹災(zāi)造成大面積農(nóng)田減產(chǎn)和絕收時(shí)有發(fā)生。煙葉抗雹災(zāi)能力最低,，為探索防御雹災(zāi)新方法,，開(kāi)展了防雹網(wǎng)防御煙田雹災(zāi)試驗(yàn)。結(jié)果表明,，防雹網(wǎng)防御煙田雹災(zāi)安全有效,，網(wǎng)本身對(duì)煙葉產(chǎn)量,、化學(xué)成分無(wú)明顯影響,，加網(wǎng)煙田發(fā)病率有所下降，是一種值得推廣的有效方法,。Abstract: Hail is one of the major disasters in tobacco production of Inner Mongolia. In this study we carried out a test to prevent hails from tobacco fields by hail-proof net. The results showed that the hail-proof net was safe and effective, and had no harmful effect to tobacco plant. The disease rate in the treated tobacco fields also decreased. Hail-proof net can be applied in hail area.
