Originaria de las praderas h\u00famedas de los Grandes Lagos de Norteam\u00e9rica e introducida en Europa en el siglo XVIII, la silfia (Silphium perfoliatum) se cultiva actualmente como cultivo energ\u00e9tico perenne: tras el segundo a\u00f1o, suele producir entre 13 y 18 t MS\/ha, o entre 6.000 y 8.000 Nm\u00b3 de metano\/ha, permaneciendo en su lugar durante m\u00e1s de quince a\u00f1os; su prolongada floraci\u00f3n estival rinde hasta 150 kg de miel\/ha y proporciona una cubierta sostenible favorable a la biodiversidad. En el jard\u00edn, tambi\u00e9n produce un atractivo follaje verde y unas caracter\u00edsticas flores amarillas en verano, que recuerdan a los campos de colza o girasol. <\/p>\n
Para plantar Silphia en buenas condiciones, hay que preparar el suelo: <\/b><\/p>\n
– Arado o descompactaci\u00f3n ligera
– incorpora una palada de compost por planta<\/p>\n
Plantaci\u00f3n<\/strong> Mantenimiento<\/strong> Riego<\/strong> Vida \u00fatil<\/strong> Usos:<\/strong><\/p>\n Forraje<\/strong> – 5-15% de prote\u00edna bruta seg\u00fan la etapa; se conserva bien ensilado<\/p>\n","protected":false},"excerpt":{"rendered":" – Planta de un a\u00f1o, altura 15-30 cm.
– Coloca el cuello a ras del suelo, apisonando moderadamente.
– Riega 10-15 L\/planta inmediatamente despu\u00e9s.
– Coloca inmediatamente 5 cm de mantillo de miscanthus (\u2248 3 L por planta): -90% de aparici\u00f3n de malas hierbas y mejor retenci\u00f3n del agua.<\/p>\n
– Azada o escarda mec\u00e1nica
– Vigilancia de babosas en la primera quincena.
– Sin laboreo en los a\u00f1os siguientes: cultivo perenne.<\/p>\n
– Mant\u00e9n un riego regular durante el primer a\u00f1o, ya que la planta se vuelve tolerante a la sequ\u00eda en el segundo a\u00f1o.<\/p>\n
– 15-20 a\u00f1os antes de que el rodal se vuelva raro; reasegura si < 80% de cobertura.<\/p>\n
– Maceta de 2 L, sustrato bien colonizado por las ra\u00edces.
– Mantillo de Miscanthus incluido: 90% menos de malas hierbas, -30% menos de evaporaci\u00f3n.
– Planta mel\u00edfera perenne que sirve de refugio a la entomofauna \u00fatil.
– Rusticidad -30 \u00b0C.<\/p>\n","protected":false},"featured_media":4131,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[107],"product_tag":[],"class_list":{"0":"post-4713","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-energia-de-biomasa","7":"desktop-align-left","8":"tablet-align-left","9":"mobile-align-left","10":"ast-product-gallery-layout-horizontal-slider","11":"ast-product-tabs-layout-horizontal","12":"ast-qv-on-image","14":"first","15":"instock","16":"taxable","17":"shipping-taxable","18":"purchasable","19":"product-type-simple"},"yoast_head":"\n
