有机、无机肥配施对黄梁木幼林生长的影响
Effects of combined application of organic and chemical fertilizers on growth of young Neolamarckia cadamba plantation
摘要
Abstract
[Objective] To explore effects of combined application of organic and chemical fertilizers on growth of young Neolamarckia cadamba plantation(YNCP).[Method]Impacts of combined application of pig manure, chicken manure , calcium superphosphate and potassium chloride on YNCP growth were studied by using orthogonal test .[Result]Combined application of organic and inorganic fertilizers had significant promoting effects on YNCP growth , with height and ground diameter growth of fertilized treat-ments being 23.53% -109.41% and 37.99% -149.06% greater than those of control treatment , respectively .Multivariate analysis indicated that pig manure and calcium superphosphate had significant effects on height and ground diameter growth , and differences among different fertilization levels were sig-nificant , but chicken manure and potassium chloride exhibited no significant effect .According to YNCP growth and fertilizer cost , the best fertilization solution was 14 kg pig manure +1.5 kg calcium super-phosphate per tree .The regression equation between pig manure ( x1 ) , calcium superphosphate ( x2 ) and tree height (yH) was yH =1.016 +0.031x1 +0.221x2 (R2 =0.835, P=0.000), and the regression equation between pig manure , calcium superphosphate and ground diameter ( yD ) was yD =26.193 +0.991x1 +6.052x2(R2 =0.832, P=0.000).[Conclusion]Combined application of organic and inor-ganic fertilizers can significantly promote YNCP growth , and 14 kg pig manure +1.5 kg calcium super-phosphate per tree have the best promoting effect .关键词
