Effects Of Different Fertilization Treatments On Growth And Changes In Soil Of Sugarcane

Sugarcane is one of the most important sugar crops in our country,the sugarcane production to relieve the contradictions of China's currentsugar demand has important significance.But,along with the increasing length of planting,soil fertility decline year by year,resulting in a dedecline in sugarcane production.Sugarcane fertilizer as a cane management important link,not only can increase the sugarcane yield and sugar content,but also improve soil nutrients,improve soil fertility.Indentured labourers brought this study in Fuzhou city of Fujian province of Fujian Agriculture and Forestry University to set up samples,using field experiment district,with slow release fertilizer A,slow release fertilizer B,compound fertilizer were used as material,discussing the effects of different fertilizer treatments on sugarcane agronomic traits,yield,sugar content and change of soil,and analysising the fertilizer utilization ratio and economic benefit of different fertilizer treatments.1.Fertilization could improve the agronomic characters in Sugarcane.Bagging slow-release fertilizer B(2 holes)has the max average height,reached 220.03cm,the plant height compared to the control increasing 13.13cm;Bagging slow-release fertilizer A(4 holes),bagging slow-release fertilizer B(2,4 holes)has higher Sugarcane stalk,the effective stalk compared with the control group were increased by 19.72%,16.89%,16.68%;bagging slow-release fertilizer B(4 holes),bagged fertilizer(2 holes)has the max stem diameter,Increased 0.21cm,0.20cm than the control.2.Fertilization can increase the cane yield and sugar yield,fertilization on yield of sugarcane production in the range of 15.25%?43.48%,bagging slow-release fertilizer B(2?4 holes)on the increase production effect is good,yield rate reaches 43.48%and 40.73%;compared with CK,fertilization can significantly increase the sugar content of sugarcane,increase yield by 177.86 kg·hm-2?391.13kg·hm-2,the bagging slow-release fertilizer B(4 holes)is the most significant to improve the sugar cane,yield rate reached 60.02%.3.Fertilization could improve soil physical properties.After fertilization Soil Physical clay content and natural moisture content compared with the control group increased,but compared with the control group were not significant.4.Fertilization soil pH decreased with the growth of sugarcane,;the content of organic matter in soil test to relative fertilization has decreased to a certain degree,but generally fertilization higher than that of control;the content of soil N,P,K increased in the fertilization.5.Bagging slow-release fertilizer A,B has more fertilizer residue,nutrient consumption is less,is conducive to improve the long-term benefit of fertilizer;Fertilization can improve the economic benefit of sugarcane,the bagging slow-release fertilizer B(2 holes),bagging slow-release fertilizer B(4 holes)has the best economic benefits,compared with the control were increased by 749.10 yuan/mu,675.01 yuan/mu.
