Abstract:

To elucidate the effects of different plant row spacing and planting depth on the growth of lily variety Siberia during the planting stage, summarize the optimal plant row spacing and planting depth for the growth of Siberia in the experimental planting site, explore key planting factors to improve the quality of cut flowers of Siberia, and seek green and efficient ways to increase yield and improve quality, using Siberia second-generation and third-generation bulbs as the experimental subjects, a standardized production process was followed, and a two factor randomized block design was used to explore the effects of different plant row spacing and planting depth on the stem height, bud size, and bud number of lily fresh cut flowers. Except for the significant impact of plant row spacing on the number of flower buds in the second-generation of bulbs at a 5% level, the effects of plant row spacing and planting depth on the other growth indicators of the second-generation and third-generation of Siberia bulbs all reached a 1% extremely significant difference level.The optimal treatment method is to combine the plant row spacing of 15 cm×20 cm with a planting depth of 25 cm in the second-generation and third-generation of bulbs. The combination of planting depth of 15 cm with a plant row spacing of 25 cm×30 cm for treatment 7 is the most unfavorable for the growth of the flower stem height and flower bud diameter of the second-generation and third-generation bulbs of Siberia, while treatment 4 is not conducive to the growth of the number of flower buds in Siberia bulbs. The influence of planting depth on the growth of the number of flower buds in the second-generation and third-generation of bulbs is greater than that of plant row spacing. The height of the flower stem and the diameter of the flower bud are different, and the planting depth has a greater impact on the growth of the flower stem height of the second-generation of bulbs than the plant row spacing between plants, while the third-generation of bulbs has the opposite effect; The influence of plant row spacing on the diameter of flower buds in the second-generation of bulbs is greater than the planting depth, while in the third-generation of bulbs, the opposite is true. In terms of the stem height and bud diameter of the second-generation and third-generation bulbs, the combination of A1B3 with a planting depth of 25 cm at a plant row spacing of 15 cm×20 cm can achieve good growth results. The combination of A3B3 with a plant row spacing of 25 cm×30 cm and a planting depth of 25 cm is beneficial for increasing the number of flower buds in the second-generation of bulbs, while A1B3 is beneficial for increasing the number of flower buds in the third-generation of bulbs. An appropriate planting depth can promote the development of plant roots and effectively absorb nutrients and water from the soil, promoting plant growth. The plant row spacing of bulbs planting is significantly positively correlated with the number of lily flower buds, flower stem height, and flower bud size.
