| 摘 要： | 为了增加土壤肥力，提高和保持土壤含水量从而提高作物产量，在山西省临汾市吉县国营红旗林场进行田间试验栽植饲料桑，对饲料桑施用新型有机肥料——生物抗蒸发保水菌肥，通过设置对照试验，探究生物抗蒸发保水菌肥的施用及用量对饲料桑生长和土壤水分状况的影响，得出试验最佳施肥量，并初步确定最大施肥量。结果显示：生物抗蒸发保水菌肥的施用可以明显提高土壤含水量，随着施肥量的增加，保水效果也会提高；合理的施用量会明显促进饲料桑植株的生长，每株施肥0.2 kg效果最佳，每株施肥量超过0.5 kg则已经抑制饲料桑的生长。本研究为该肥料的推广应用以及饲料桑的种植提供可行的理论依据。

The Effect of Biological Fertilizer with Anti-evaporation and Water-conservation Features to the Growing and Soil Moisture of Morus alba L |
| |
| Abstract: | Morus alba L has been planted through field experiment in Hongqi State-operated Tree Farm located in Ji County, Linfen City, Shanxi Province. Biological fertilizer with anti-evaporation and water-conservation features had been applied to Morus alba L to improve the soil fertility, increase and maintain the soil moisture content so that the production could be increased. The effect of the fertilizer application and dosage on soil moisture and growing state of Morus alba L had been studied through setting control group. The results indicated that the application of biological fertilizer with anti-evaporation and water-conservation features could increase moisture content significantly and the degree improved with the increasing of dosage. Proper dosage could notably promote the growing of the Morus alba L and 0.2 kg per plant could be the most proper dosage. And this experiment would provide a viable theoretical basic for this fertilizer and Morus alba L widespread planting in the experiment district. |
