Abstract

Abstract:

【Objective】 This project aims to explore the effects of different planting row spacing on the production and water-saving efficiency of spinach and optimize the efficient and water-saving planting mode of facility spinach. 【Methods】 Mexico 2 spinach was taken as the test material, a field experiment was conducted in a vinyl house, and three kinds of row spacing was set for drill planting to study the effects of row spacing of 10 cm (T₁), 15 cm (T₂) and 20 cm (T₃) on yield, dry matter quality, water consumption and water use efficiency of spinach with uniform sowing (CK) as the control. 【Results】 The results showed that equal row spacing seeding significantly promoted the growth and yield of spinach in facilities.Compared with CK, the yield under T₁, T₂ and T₃ treatments increased by 4.39%, 6.34% and 10.04%, respectively.Among them, the yield and water use efficiency of spinach under T₃ treatment were significantly higher than those under T₁ and T₂ treatment.T₃ treatment not only promoted the dry matter accumulation of spinach, but also showed the lowest daily water consumption intensity during the harvest period, thus improving the water use efficiency.Compared with CK, the dry matter quality of spinach plants under T₃ treatment increased by 10.05%, and the population yield increased by 10.04%.Water consumption during the whole growth period decreased by 18.84%; Water use efficiency increased by 26.52%. 【Conclusion】 In summary, in the process of spinach production, the 20 cm row spacing drill planting mode is the most beneficial to improve the yield and water use efficiency of facility spinach, so it is strongly recommended to be popularized and applied.

摘要：

【目的】 探究不同种植行距对菠菜生产及节水效率的影响,优化设施菠菜高效节水种植模式。【方法】 以墨西哥2号菠菜品种为材料,在塑料大棚内试验,设置3种条播种植行距为10 cm(T₁处理)、15 cm(T₂处理)、20 cm(T₃处理),以撒播(CK)为对照,研究种植行距的变化对菠菜产量、干物质量、耗水以及水分利用效率的影响。【结果】 等行距条播种植显著促进了塑料大棚菠菜的生长和产量,与CK相比,T₁处理、T₂处理、T₃处理下的产量分别提高了4.39%、6.34%和10.04%。其中,T₃处理下菠菜的产量和水分利用效率明显高于T₁处理和T₂处理,T₃处理不仅促进了菠菜的干物质积累,并且在收获期表现出最低的日耗水强度,从而提高了水分利用效率。与CK相比,T₃处理下菠菜的植株干物质量提高了10.05%,群体产量增加了10.04%;全生育期耗水量减少了18.84%;水分利用效率提高了26.52%。【结论】 20 cm行距的条播种植模式有利于提高大棚菠菜的产量和水分利用效率,可在生产上推广应用。
