The Influence of Population Density of Winter Wheat of Plastic Film Mulching on Ridge for Rainwater-harvesting on Yield
摘要
Abstract
Field experiments were carried out to study the influence of density on yield of winter wheat in different ridges mulched with plastic film for rainwater-harvesting. There was one type of plastic film mulching on ridge for rainwater-harvesting, which had the furrow width and ridge width of 60 cm. Three planting densities of high, middle and low level were used in the plastic film mulching on ridge for rainwater-harvestings.There were four, three and two lines wheat planted in the furrow in the high, middle and low planting density, respectively. The results showed that the rainwater-harvesting played the role in promoting the rapid growth of wheat and making the production of wheat to increase. in the low population density, the number of tillering, the aboveground biomass and the seed yield were the highest in the plastic film mulching on ridge for rainwater-harvesting. In the middle and high population density, there had an intensive competition,which resulted in the death of more tillers in middle lines, and the low percentage of tillers, and which was also the main reason for the lower yield in these practices.关键词
