密度和缓控释肥对红花标记杂交棉鲁05H9生育进程及产量的影响
Effects of Density and Slow Controlled Release Fertilizer on Growth Progress and Yield of HB Cotton Hybrid Lu 05 H9
摘要
Abstract
With the HB hybrid Lu 05H9 as experiment material, the effects of slow controlled release fertilizer on growth progress and yield of cotton were studied under different densities .The results showed that the growth progress of Lu 05 H9 was stable under different treatment conditions .The treatment with slow con-trolled release fertilizer made the percentage of four kinds of boll more reasonable , and increased the percent-age of summer boll and early-autumn boll .The number of population bolls and total yield increased with the increase of density , but the number of bolls per individual plant and average single boll weight decreased . Plant density had the significant influences on the boll number per plant .Compared with the conventional fer-tilizer, the slow controlled release fertilizer could improve the average weight of single boll , but reduce the yield and its components .The interaction effect of density and fertilizer was insignificant on yield and its com-ponents .The economic benefit could increase by 472 yuan per hectare with slow controlled release fertilizer at the density of 42 thousand plants per hectare .So considering higher economic and environmental benefit , the cultivar Lu 05 H9 could be applied in the Yellow River zone combined with higher density and slow controlled release fertilizer .关键词
