不同株距对“金鹏11号”番茄生长发育及产量的影响

Effects of Different Planting Spacing on the Growth and Yield of “Jinpeng 11” Tomato

以"金鹏11号"番茄为试材,在不同的栽培株距下,测量番茄的形态、生理、单果质量及产量指标,研究不同株距对番茄生长发育及其产量的影响。结果表明,株距不同,植株的株高、茎粗长势差异显著,40cm株距的株高和茎粗明显高于其他3个水平。植株叶绿素含量、光合强度、单果质量等随栽培株距的增加明显增加。产量随株距的增加表现为先上升后下降,株距为40cm时产量最高,25cm时产量最低。综合各形态、生理及产量指标,以40cm株距的产量显著高于其他各水平,达到6 500kg/667m2,得出温室最佳栽培株距为40cm。

The research was aimed to study the influence of different planting spacing on the growth, development and the yield of tomato and to provide an important and scientific instruction for the tomato production. “Jinpeng 11” tomato was used as the test material, and the morphological indexes, physiological indexes, fruit mass and yield indexes were measured under different planting spacing. The results showed that the plant height and stem diameter were remarkably influenced by the different planting spacing, and the highest value was obtained under planting space of 40 cm. At the same time, with the increasing of planting spacing, the content of chlorophyll, the strength of photosynthesis and the single fruit mass were significantly increased, the yield increased firstly and then decreased, and the the highest yield of tomato was produced at planting space of 40 cm, and the lowest yield was at 25 cm. Based on the physiological, morphological and production indicators, and the highest yield of 40 cm , which was 6 500 kg/667 m2, the optimal planting spacing of the tomato cultivar in the greenhouse was 40 cm.
