多样性种植模式对糯高粱生长及高梁炭疽病发生的影响

旨在阐述多样性种植模式对于糯高粱农艺性状、生理特性的影响及防控高梁炭疽病的效果，为推广糯高粱栽培技术和防控高梁炭疽病进一步提供理论依据。采用糯高粱与大豆、花生间套作，同时应用隔年换带轮作技术，结果表明：与单作糯高梁比，多样性种植模式对糯高梁的穗长、千粒重、穗粒重等农艺性状有一定影响；多样性种植模式对糯高粱开花期的净光合速率、蒸腾速率、气孔导度、胞间CO2浓度等光合特性有显著性影响；多样性种植模式对高梁炭疽病发病株率、病情严重度分级、病情指数有显著性影响；对高粱炭疽病的防控，A2B2种植模式相对防控效果最好，高达71.95%。糯高梁与大豆、花生间套作的多样性种植模式对糯高粱生长有影响，能够提高糯高粱光合能力，有效控制高梁炭疽病的发生，对大面积生产具有较大的利用价值。

Diversity Planting Pattern: Effect on Waxy Sorghum Growth and Sorghum Anthracnose

The purpose of this study was to explain the effects of diversity planting patterns on the growth of waxy sorghum and the control of sorghum anthracnose. It provided theoretical basis for popularizing the cultivation of waxy sorghum and controlling sorghum anthracnose. Waxy sorghum was intercropping with soybean and peanut, and at the same time, applying the technology of crop rotation, the results showed that compared with waxy sorghum monoculture, the diversity planting patterns had certain influence on the agronomic characters of waxy sorghum, such as ear length, 1000-grain weight and panicle grain weight; the net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO2 concentration in the diversity planting patterns were higher than those of waxy sorghum monoculture, and significant difference with waxy sorghum monoculture; the incidence rate of plant, the severity of the disease and the disease index in the diversity planting patterns were lower than those of waxy sorghum monoculture, and significant difference with waxy sorghum monoculture; the relative control effect of A2B2 planting model was the best, up to 71.95% in the control of sorghum anthracnose. The intercropping pattern of waxy sorghum, soybean and peanut have some influence on the agronomic traits，can improve the photosynthetic ability of waxy sorghum, effectively control the occurrence of sorghum anthracnose, and have great value potential in production.
