温室盆栽一品红水肥耦合效应研究
Coupling effect of water and fertilizer on potted Euphorbia pulcherrima in greenhouse.
-
摘要: 为降低盆花生产成本和提高水肥利用率，实现盆花生产的精准控制，采用盆栽试验，利用二次通用旋转组合设计的方法，研究浇水频率和施肥量对一品红株高、冠幅、生物量、花期和花头数的影响。结果表明，浇水频率和施肥量对一品红盆花的株高、冠幅、生物量和花期有明显影响，其中施肥量对品质的影响大于浇水频率。建立的回归模型均准确可靠，可用于生产预报。通过方程拟合和模拟寻优，得到以V(玉米秆粉)∶V(锯末)∶V(珍珠岩)为2∶1∶1的基质配方栽培一品红盆花的最佳水、肥供应模式：基质含水量为59.28%～66.83%进行浇水，浇水量为500.00 mL/盆；每周施肥1次，施肥量为756.02～833.33 mg/盆。

Abstract: In order to reduce the production cost and improve the utilization efficiency of water and fertilizer, and to realize the precise control of potted flowers, we studied the effect of different watering frequencies and fertilizer amounts on the plant height, crown diameter, biomass, blooming duration and number of flowers of Euphorbia pulcherrima by pot culture and quadratic general rotary design. The results indicated that watering frequency and fertilizer amount markedly affected the plant height, crown diameter, biomass and blooming duration of E. pulcherrima, and fertilizer amount had more obvious impacts than watering frequency. The regression models were both accurate and reliable, and could be used for prediction of production. The optimum matching control methods of water and fertilizer were found for E. pulcherrima in a growth medium V(corn stalk)∶V(sawdust)∶V(perlite)=2∶1∶1 by equation fitting and simulating optimization. The optimum watering frequency was: once the water content of the medium ranged from 59.28%-66.83%, watering 50000 mL per pot; the optimum fertilizer amount was 756.02-833.33 mg per pot, once a week. -
