【目的】为科学安排日光温室生产茬次、高效栽培番茄及合理密植提供理论依据。【方法】采用单干整枝方式研究不同密度及果穗数对温室冬春茬栽培番茄干物质生产与分配的影响。【结果】温室番茄定植密度对干物质生产的影响较大,保留果穗数间接影响干物质的分配。摘心前期,不同密度间单位面积群体植株总干重存在差异显著性变化,处理4 000株/667 m2单位面积群体干物质生产最多,主要分配于茎叶供给营养生长。在适宜保留果穗数下,干物质生产影响植株上的坐果穗数,从而间接影响植株内干物质分配,不同密度及适宜留果穗数下干物质生产与营养器官和生殖器官的分配比例有关。【结论】在密度为4 000株/667 m2(3穗果)时,既能实现营养生长期茎叶干物质的最大生产又能实现生殖生长果实最大分配累积,前期产量最高达4 310.7 kg/667 m2。
【Objective】 To provide theoretical basis for scientific arrangement of crop production in solar greenhouse, efficient cultivation of tomato and close planting. 【Method】 The effects of different densities and spike numbers on the dry matter production and distribution of tomato cultivated in winter and spring in greenhouse were studied by single stem pruning method. 【Result】 The results showed that the density of tomato planting in greenhouse had a great effect on the production of dry matter, and the number of retained ear indirectly influenced the distribution of dry matter. The total dry weight of the plants per unit area between different densities had significant difference at the early stage of topping, and the dry matter production per unit area of 4 000 plants / 667 m2 was the most, which was mainly distributed in vegetative growth of stems and leaves. Under the appropriate reserved ear number, the dry matter production affects the number of plantation spikes on the plant, which indirectly affects the distribution of dry matter in the plant, and the density of dry matter and the proportion of the distribution of vegetative organs and reproductive organs under different densities and suitable spikelets. 【Conclusion】 The results showed that when the density was 4 000/667 m 2 (3 spikes), the maximal production of stem and leaf dry matter in vegetative growth stage and the maximum distribution and accumulation of reproductive growth fruit could be achieved. The highest yield reached 4 310.7 kg / 667 m2.
