【摘要】 以从汝城朝天椒中新选育的优良株系SYT20为材料，开展了SYT20栽培行株距及单双株栽培模式的研究。结果发现，汝城朝天椒SYT20株高、主茎高在单双株栽培模式下，双株栽培显著高于单株栽培，单株栽培的主茎粗大于双株栽培，但株（穴）距对其影响并不显著；单株（穴）结果数双株栽培大于单株栽培，株（穴）距越大结果数越多；单株栽培的产量以35单株最高，折合产量为1 127.45 kg/667 m~2，双株栽培的产量以30双的平均产量最高，折合产量为1 196.85 kg/667 m~2，但30双与35单、35双、40双和45双都未达到显著性差异。综合考虑栽培密度、种苗用量对增产效果的影响，建议SYT20株系采用株行距35 cm×60 cm单株栽培为宜。SYT20株系栽培密度的研究结果为制定汝城朝天椒标准化栽培技术规程提供了科学依据。更多还原

【Abstract】 The excellent strain SYT20 newly bred from pod pepper in Rucheng was used as the material, and the planting spacing and cultivation modes of single-plant and double-plants of SYT20 were studied. The results showed that the plant height and main stem height of Rucheng pod pepper SYT20 in double-plants cultivation model were significantly higher than that of single-plant cultivation. The main stem thickness of single-plant cultivation was greater than that of double-plants cultivation, but the plant(hole) distance had no significant effect on it. The number of fruits per plant for double-plants cultivation was greater than that of single-plant cultivation, and the larger the plant(hole) spacing, the more the number of fruits. The highest yield was obtained for single-plant cultivation of 35 plants, which was 1 127.45 kg/667 m~2. For double-plants cultivation, the highest yield was obtained of 30 double-plants, which was 1 196.85 kg/667 m~2. However, there was no significant difference between 30 double-plants and 35 single-plant, 35 double-plants, 40 double-plants and 45 double-plants respectively. Considering the effects of cultivation density and seedling amount on yield increase, it was suggested that SYT20 should be cultivated with a planting spacing of 35 cm × 60 cm. These results provide a scientific basis for the formulation of standardized cultivation technical regulations for pod pepper SYT20 in Rucheng.更多还原
