不同钙素肥料对大蒜农艺性状及产量的影响

Effect of Different Calcium Fertilizers on Agronomic Characters and Yield of Garlic

受黄河冲积性水源的影响,中牟县土质呈弱碱性反应,常年种植大蒜易造成植株生长不良,产量与品质下降比较明显。现以大蒜为试验材料,采用硫酸钙(生石膏粉)、氯化钙、过磷酸钙、钙镁磷肥、不施钙素肥料(CK)进行试验对比,找出适宜于当地生产的钙肥,为科学施用钙肥提供依据。结果表明:钙素肥料处理后植株具有均衡生长作用,硫酸钙、氯化钙、过磷酸钙、钙镁磷处理后株高分别较对照平均株高矮化0.98%、3.57%、1.95%、2.79%,其中硫酸钙处理的株高处于最佳范围,植株最健壮;叶绿素SPAD值分别较对照提高10%、8%、7%、8%;3个试验点钙肥处理后,大蒜单果重和增产幅度均表现为硫酸钙最高,其次分别为氯化钙、过磷酸钙、钙镁磷、对照。

By the impact of the Yellow River alluvial water,the soil of Zhongmu County take on weakly alkaline reaction. Due to the local farmers planting garlic all the year round on the soil, causing the poor plant growth,and bring down the yield and quality. Taking garlic as test material in this experiment,adoptting the contrast test of calcium sulfate （gypsum powder）, calcium chloride, calcium superphosphate, calcium magnesium phosphate fertilizer, without calcium fertilizer （CK） to find out a calcium fertilizer which was suitable for local production, and provided the basis for the scientific application of fertilizer. The results showed that the calcium fertilizer treated plants were balanced function, calcium sulfate,chloride, calcium superphosphate, calcium magnesium phosphate processing plant were higher than the control average plant dwarfism 0. 98% ,3. 57%, 1.95% and 2. 79% ,and the plant height was dealt with calcium sulfate were in the optimum range,and the plants were beefiest; chlorophyll SPAD value respectively,compared to the control increased by 10% ,8%,7% and 8%;after three trials of calcium treatment, garlic fruit weight and yield increment showed that calcium sulfate was the highest, calcium chloride was the second, superphosphate was the third, calcium-magnesiumphosphorus was the fourth, the control was the fifth.
