查询词典 single-crop

The experiments were conducted with one-crop cultivar and two-crop cultivar of Iris germanca . Photoperiod in nature condition and the effects of different photoperiods on flower bud differentiation and photosynthetic characteristics were investigated.

本试验以德国鸢尾一次花和二次花品种为材料，从植株生物学特性和光合特性两个层面上，研究一二次花品种在自然状况下的光合特性以及不同光周期对其花芽分化和光合特性的影响。

Short-day treatment with stronger the photosynthetic capacity in leaves per unit area of two-crop cultivar, but longer day treatment with stronger the total photosynthetic capacity; Longer day treatment with stronger the photosynthetic capacity in leaves per unit area of one-crop cultivar.

短日照下二次花单位叶面积的光合能力较强，但其总体光合能力是长日照大于短日照；长日照下一次花植株单位叶面积的光合能力较强。

Different photoperiods:⑴ Long-day treatment accelerated the process of flower bud differentiation and increased the numbers of the flower buds of two-crop cultivar; short-day treatment accelerated the process of flower bud differentiation of one-crop cultivar, but long-day treatment increased the numbers of the flower buds per inflorescence.

不同光周期下：⑴长日照促进二次花品种的花芽分化进程和单花序上花芽数量的增加；短日照加速了一次花品种植株花芽分化进程，而长日照促进了其单花序上花芽数目的增加。

A univariate ANOVA is executed to analyze the influencing factors of the production cost by dividing it into direct material, direct labor cost, indirect cost and total cost separately. It is found that the variables of farm scale and crop type show significant impacts in the direct labor cost and total production cost. The one-crop farming variable makes significant difference in the total production cost; whereas different planting ways differentiates the indirect cost. In addition, years of farming, farmer's age, and full-time status all make no significant difference in all aspects of production cost.

此外，将农场生产成本分为直接材料、直接人工、间接成本、总生产成本四面向进行多因子变异数分析，结果发现耕作面积、作物类型变项仅在有机农场的直接人工和总生产成本中有显著差异；有机农场是否为单一经营在总生产成本上有显著差异；不同栽培方式的有机农场仅在间接成本的高低上有显著差异；此外，而耕作年数变项因本研究有机农场耕作年数较高之样本特性影响，导致该变项对生产成本并无显著的差异；年龄、专兼业经营等变项在生产成本上高低并无显著差异。

Out-of-season crop; off-season crop

调职；产量；产出；产出物
