施用土壤改良劑對結球白菜(桃亞二號)生長之影響

Effect of Application of Soil Amendmentson the Growth of Chinese Cabbage (Taoyuan Yiasu No.2)

摘要


本試驗於本場新屋試驗田進行,目的在探討施用苦土石灰、根源、堆肥及噴施檸檬酸等處理,對夏季結球白菜(桃亞二號)之生長效果,以提供農民參考。82、83年度試驗田土系依F.C.C.分類均為Cha,試驗前土壤性質82年試區為pH5.4,有機質含量3.6%,EC值0.52 dS/m25℃,有效性磷、鉀、鈣、鎂含量分別為17、142、1,580、222 mg/kg,83年試區為pH5.4,有機質含量2.7%,EC值0.85 dS/m25℃,有效性磷、鉀、鈣、鎂含量分別為36、103、767、125 mg/kg。每公頃施用2噸的苦土石灰可明顯增加土壤pH值有效性鈣、鎂的含量,並顯著提高結球白菜球葉中鈣、鎂的含量,而每公頃施用20噸根源或堆肥則可提高土壤有機質含量。每公頃施用苦土石灰2噸後再加20噸之堆肥或根源或噴施0.5%檸檬酸、0.5%硫酸鈣等處理,於82年試區可較對照區增產7~42%,且效果達顯著差異水準,而83年試區中單一施用均可達增產效果,唯差異未達顯著水準。

The experiments were conducted in the fields of Taoyuan DAIS for studying the effects of application of dolomite, bark slag, compost and citric acid on the growth of Chinese cabbage (Taoyuan-Yiasu No.2) in summer. The results of experiment might be provided the methods of planting Chinese cabbage for farmers.According to F. C. C, the soil series of experimental farm were all Cha in 1993 and 1994. The soil properties before experiment in 1993 were pH 5.4, O.M. 3.6%, E.C. 0.52 dS/m25℃ and the contents of available P, K, Ca, Mg were 17, 142, 1580, 222 mg/kg, respectively. In 1994's experimental farm, the soil properties were pH 5.4, O.M. 2.7%, E.C. 0.85 dS/m25℃, and the contents of available P, K, Ca, Mg were 36, 103, 767, 125 mg/kg, respectively. Application of dolomite with 2 tons/ha obviously increased the available Ca and Mg contents of soil, and significantly increased the Ca and Mg contents of ball leaves of Chinese cabbage. Application of bark slag or compost could increased the soil organic matter content.After application of dolomint with 2 tons/ha, and bark slag or compost with 20 tons /ha, or spraying 0.5% citric acid or 0.5% calcium sulfate, showed significantly in increase of Chinese cabbage yield for 7 to 42% higher than that without application treatment in 1993's experiment. In 1994's experiment, application of single material showed able to increase the yields of Chinese cabbage, but were not significantly different among the treatments.
