不同类型肥料施用深度和施用量对冬小麦生长发育的影响
Effects of Application Depth and Amount of Different Types of Fertilizers on Growth and Development of Winter Wheat
摘要
Abstract
Three types of fertilizers were selected with no fertilization as control(CK),including tower granulation compound fertilizer,agglomeration granulation compound fertilizer,and controlled-release mixed compound fertilizer.Three application rates were set,including 600 kg/ha(F1),750 kg/ha(F2)and 900 kg/ha(F3),and three application depths were set,including 6 cm(D1),8 cm(D2)and 10 cm(D3).The effects of application depth and rate on the plant height,aboveground fresh weight,root length,root diameter,root volume,root surface area,and root tip number of winter wheat seedlings were studied,so as to provide a theoretical basis for the rational adjustment of application depth and rate based on fertilizer types in winter wheat production.The results indicated that when the application rate was F1 and the application depths were D2—D3,the tower granulation compound fertilizer had a promoting effect on the growth and development of winter wheat,with membership function values of 0.70 and 0.77 respectively(the membership function value of CK was 0.61),and the F1D3 treatment had the best effect,significantly increased root length,root volume,root surface area and root tip number compared with CK.When the application rates were F1—F3 and the application depth was D3,the agglomeration granulation compound fertilizer had a promoting effect on the growth and development of winter wheat,and the F2D3 treatment had the best effect with membership function value of 0.86,significantly increased plant height,aboveground fresh weight,total root length,root diameter,root volume,root surface area and root tip number compared with CK.When the application rates were F1—F3,and the application depths were D2—D3,the controlled-release mixed compound fertilizer had a promoting effect on the growth and development of winter wheat,and the F1D2 and F1D3 treatments had better effects with membership function values of 0.93 and 0.92 respectively,significantly increased plant height,aboveground fresh weight,root length,root volume,root surface area and root tip number compared with CK.Under the same application rate and application depth,the membership function values generally showed controlled-release mixed compound fertilizer>agglomeration granulation compound fertilizer>tower granulation compound fertilizer.In conclusion,the F1D3 treatment is the best for the tower granulation compound fertilizer,the F2D3 treatment is the best for agglomeration granulation compound fertilizer,the F1D2 and F1D3 treatments are better for the controlled-release mixed compound fertilizer,and the controlled-release mixed compound fertilizer has the best effect.关键词
