滴灌条件下水肥耦合对花生干物质积累和产量的影响
Effect of Drip Irrigation and Fertilizer Coupling on Peanut (Arachis hypogaea L.) Dry Matter Accumulation and Its Yield
摘要
Abstract
[Objective] In order to study the effect of irrigation and fertilizer coupling on peanut dry matter accumulation dynamic,physiological index and yield,in this experiment,Huayu 33 was used as fertilizer to analyze the effect of water and fertilizer coupling at different growth stages.[Method] The experiment was divided into five parts:no fertilizer(A control),seedling fertilizing (B),top dressing at flowering stage (C),floricome period fertilizing (D),pod setting period fertilizing (E) according to the different fertilizer periods.The quantity of fertilizer was the same with each other:N 180 kg,90 kg P2O5,K2O 45 kg and CaO 30 kg for per hectare.[Result] During pod setting period,fertilization promoted the growth of peanut plant height;The ratio of root to shoot of peanut was the highest at the beginning period of flowering,which showed that fertilization in this period was conducive to the reproductive growth and dry matter accumulation of peanut.At the same time,according to the table of area yield,at the beginning of flowering period,fertilizing the peanut,peanuts area yield was the highest,reaching 527.93 kg;The analysis of peanut per plant and main agronomic characters showed the stem height,lateral branch length,the total number of branches,number of fruit,full fruit number per plant,hundred kernel weight and other agronomic traits had the impact on individual plant productivity;fertilization at floricome period was conducive to the growth of the agronomic traits and to improvement of peanut productivity per plant.[Conclusion] In conclusion,water and fertilizer treatments have different effects on peanut at different developmental stages,and fertilization at first flowering stage can increase peanut yield per mu and create more revenue.关键词
