Abstract
為提倡使用機械化生產蔬菜，本試驗採用寬行密植式栽培代替傳統之狹行疏植生產青花菜，並究明寬行密植式栽培對於青花菜之生育、產量及品質之影響及使用機械化栽培之可行性。
根據本研究結果，青花菜栽培可以利用小型耕紜機整地、開基肥溝以及作1.4公尺寬之畦以代替傳統之耕作方法1.2公尺寬者。根據本試驗寬行（70公分）密植（20~50公分）結果獲知，株距減小時，平均地上部全株重、平均花蕾重、平均葉重、平均花蕾徑、莖徑、側芽數、側芽重均有減少之趨勢，但單位面積內花蕾產量則有增加之可能。為配合使用機械操作及綜合試驗分析結果，栽植密度以採用1.4公尺寬之畦上種植兩行，或以70公分之行距配合30公分之株距，可獲得最有利之產量及品質。
In order to provoke and develop vegetable culture by use of machines, the close planting in wide-spacing rows was adopted by this experiment to replace the conventional loose planting in narrow-spacing rows for broccoli production improvement. And the effects of close planting (20-50 cm apart) in wide spacing rows (70 cm apart) on the growth, yield and quality of broccoli, and the feasibility of mechanization were also ascertained.
Based on this study, power tillers (15 H. P.) could be used for soil preparation, furrow opening, and making 1. 4m wide beds instead of making the conventional 1.2 m wide beds. It was apparent from the experimental results that as the plants were placed closer together, the mean weight of plants above ground, the mean weight and diameter of central flower heads, the mean weight of foliage per plant, the mean diameter of stems, the mean number and weight of lateral shoots per plant, etc. decreased. However, the higher yield of the central flower heads per unit area could be obtained. It is concluded that the highest yield of quality broccoli can be obtained with the planting density of 0.7 m x 0.3 m which can also meet the operation of machines.
