硫肥对大白菜生长及产量的影响

Effects of Sulfur Fertilizer on Growth and Yield of Chinese Cabbage

以‘丰抗78’和‘金秋理想’2个大白菜品种为试材,采用0、25、50 kg/hm2硫肥不同施用量,应用随机区组设计,研究了硫肥对大白菜生长及产量的影响。结果表明,硫肥对大白菜开展度、最大叶宽、最大叶柄长和球高有显著影响,对大白菜产量指标的影响达极显著水平。在硫肥量25 kg/hm2时,大白菜生长状况较好、产量最高,此时‘丰抗78’和‘金秋理想’产量分别为71 428.6和75 000.0kg/hm2。

Effects of sulfur fertilizer on growth and yield of Chinese cabbage were researched using ＇ Fengkang 78＇ and ＇ Jinqiulixiang＇ as ma- terials. Sulfur fertilizer amount was 0, 25, 50 kg/hm2 respectively, and randomized block design was applied. The results showed that sulfur fertilizer had significant effect on plant diameter, maximum leaf width, petiole length and head length, and the effects of sulfur fertilizer on yield indexes reached extremely significant level. When sulfur fertilizer application rate was about sufur 25 kg/hm2 , the plants well grow and had the highest yield. The yield of ＇ Fengkang 78＇ and ＇ Jinqiulixiang＇ was 71 428.6 and 75 000.0 kg/hm2, respectively.
