早春日光温室黄瓜氮肥施用密度与产量的关系
Study on Relationship among N Fertilizer,Plant Density and Yield of Cucumber in Solar Lean-to Greenhouse in Early Spring
【摘要】 以津春3号黄瓜为试材,采用D-饱和最优设计的方法,试验结果经计算机运 算,建立了氮肥、密度与黄瓜产量关系的回归方程,经计算机模拟,筛选出每667m2产量高于4500kg的优化组合为:每667m2施纯氮26.0 6~41.84kg,种植密度3395~3861株。
【Abstract】 A regression equation of cucumber yield related to N f ertilizer,plant density was set up by using the D-saturated optimatation desig n method. The optimum combination to get yield 67.5t·hm-2 by comp uter simulating is N 390.9~627.9kg·hm-2 density of 50925 ~57915 plants per hectare.
