为了研究萝卜磷肥最佳施用量,进一步修正和完善萝卜磷肥施肥技术,为萝卜施肥分区和肥料配方提供科学依据,特设计本试验。试验在施用适量有机肥为底肥的基础上进行,设5个处理、3次重复,采用完全随机区组设计,小区面积33.6 m2。试验数据表明,岳普湖镇中等以下肥力条件下萝卜地施尿素在39 kg/0.067 hm2,分两次追肥,前期少量后期多量,能有效提高萝卜产量,达到5 000 kg/0.067 hm2的目标。
In order to study the optimum application rate of radish phosphate fertilizer, we further amended and improved the fertilization technology of radish phosphate fertilizer and provided the scientific basis for radish fertilizer division and fertilizer formula. We designed this experiment specially. The experiment was carried out on the basis of application of appropriate amount of organic fertilizer as base fertilizer, with 5 treatments and 3 repetitions. The design was completely randomized and the plot area was 33.6 m2. The experimental data showed that urea yield of radish was 39 kg / 0.067 hm2 under moderate and medium fertility conditions in Yuepuhu town, with two topdresses at a small amount in the early period, which could effectively increase the yield of radish and reach the target of 5 000 kg / 0.067 hm2.
