高产剑麻的养分累积特性

Accumulation Characteristics of Nutrients in High-yield Sisal

为了解高产剑麻的养分累积特性,分析了高产剑麻不同器官中的养分含量。结果表明:高产剑麻干物质在根系、茎和叶片中的累积比例分别为24%、40%和36%。N、P、K主要积累在叶片和茎中,Ca、Mg和Cl主要积累在叶片中,S、Zn、B和Mo主要积累在茎中。每生产1t高产剑麻叶片对N、P2O5、K2O、CaO、MgO、S、Cu、Zn、B、Mo和Cl的吸收量分别为3.20kg、0.34kg、3.26kg、9.36kg、0.81kg、0.80kg、1.43g、7.00g、4.27g、0.04g和67.68g,每收获1t剑麻叶片被带走的N、P2O5、K2O、CaO、MgO、S、Cu、Zn、B、Mo和Cl分别为1.34kg、0.16kg、2.14kg、5.24kg、0.55kg、0.28kg、0.31g、2.49g、1.80g、0.01g和37.01g。

The nutrient contents in different organs were analyzed to explore the accumulation characteristics of nutrients in high-yield sisal.The results showed that the accumulation proportion of dry matter in root,stem and leaf was 24%,40% and 36% respectively.N,P and K mainly accumulated in leaf and stem.While Ca,Mg and Cl mainly accumulated in leaf,and S,Zn,B and Mo mainly accumulated in stem.For producing 1 t high-yield sisal leaves,the absorption amount of N,P2O5,K2O,CaO,MgO,S,Cu,Zn,B,Mo and Cl was 3.20 kg,0.34 kg,3.26 kg,9.36 kg,0.81 kg,0.80 kg,1.43 g,7.00 g,4.27 g,0.04 g and 67.68 g respectively.And the removal amount was 1.34 kg,0.16 kg,2.14 kg,5.24 kg,0.55 kg,0.28 kg,0.31 g,2.49 g,1.80 g,0.01 g and 37.01 g separately.
