休闲期施肥覆盖对旱地小麦越冬期幼苗生长的影响
Effect of Covering and Fertilizer in Leisure Period on Wintering Wheat Growth under Dryland Condition
摘要
Abstract
Field test was carried out to study the effect of different covering and fertilizer in leisure period on soil water storage at the depth of 0-20 cm,on plant growth, and on the activities of POD and SOD, and MDA content in wheat leaves in under dryland condition, thus through the farming technique reformation to form strong wheat before wintering . The results showed that soil water storage at the depth of 0 - 20 cm, tiller numbers and dry weight in plant, POD and SOD activity were increased, and MDA content was decreased under the treatment of the farmyard fertilizer. The results also indicated that the soil water storage at the depth of 0~20 cm, tiller numbers and dry weight in plant, POD and SOD activity were the highest under the treatment of water permeability plastic film mulching (PM), and the lowest under the treatment without covering(CK) among the three treatments. The soil water storage at the depth of 0 - 20 cm and dry weight in plant were significantly increased under the treatment of PM. MDA content was the highest under the treatment of CK, and the lowest under the treatment of PM among the three treatments. So, farmyard fertilizer and PM increased the soil water storage and plant growth in wheat under dryland condition.关键词
