摘要
针对湖南油茶栽培分布区的6大土壤类型,采用测土配方原则,应用立地养分效应模型,结合油茶基础生物量、平均生物量和目标生物量等,研究了在湖南6大土壤类型栽培区盛果期油茶施肥的N,P,K配比及施肥量。结果表明:酸性紫色碎屑岩紫色土、紫砂土配比按N∶P∶K=3.5∶1∶3.5,年施肥量为3.6kg/株;板页岩红壤配比按N∶P∶K=3∶1∶3,年施肥量为3.2kg/株;碳酸盐岩红壤配比按N∶P∶K=3.2∶1∶3.3,年施肥量应为3kg/株;泥灰岩红壤灰红壤配比按N∶P∶K=3.3∶1∶3.5,年施肥量为3kg/株;砂页岩红壤沙红壤配比按N∶P∶K=3.1∶1∶3.1,年施肥量为3.5kg/株;花岗岩麻砂土配比按:N∶P∶K=3.5∶1∶3.5,年施肥量为3.6kg/株。
According to the six soil types of Camellia cultivation area in Hunan,and using the principles of soil testing,applying site nutrient effects model,and combining the basic biomass,average biomass and objectives biomass of Camellia,the fertilizer ratio of N,P,K and fertilizer volume of Camellia in full fruit period of six soil types of the cultivation area in Hunan were proposed in the paper.The results show that the fertilizer ratio of acid purple rocks purple soil and purple soil was N∶P∶K=3.5∶1∶3.5,and 3.6 kg per plant in a year.The ratio of fertilizer of board shale red soil was N∶P∶K=3∶1∶3,and 3.2 kg per plant in a year.The ratio of fertilizer of carbonate red soil was N∶P∶K=3.2∶1∶3.3,and 3 kg per plant in a year.The ratio of fertilizer of marl red ash soil was N∶P∶K=3.3∶1∶3.5,and 3 kg per plant in a year.The ratio of fertilizer of sandstone red soil and red sand soil was N∶P∶K=3.1∶1∶3.1,and 3.5 kg per plant in a year.The ratio of fertilizer of granite hemp sandy soil was N∶P∶K=3.5∶1∶3.5,and 3.6 kg per plant in a year.
