Es la cantidad de horas que pasaron a temperatura bajo<br>7\u00b0C entre el inicio del invierno y la llegada de la primavera. Se llama requerimiento de horas<br>fr\u00edo y define si un \u00e1rbol va a despertar de manera uniforme, vigorosa y productiva, o si va a<br>brotar de forma err\u00e1tica, con floraci\u00f3n dispersa y cuajado deficiente.<\/p><p><br>El requerimiento var\u00eda por especie y por variedad. El manzano Fuji necesita entre 1.000 y<br>1.200 horas. El cerezo Lapins, alrededor de 900. El kiwi Hayward, entre 700 y 1.000. El<br>nogal, entre 700 y 1.500 seg\u00fan el genotipo. El ar\u00e1ndano, entre 200 y 1.000 seg\u00fan la<br>variedad. Si el invierno no acumula las horas suficientes, el \u00e1rbol no completa su dormancia<br>y los problemas son casi inevitables: brotaci\u00f3n heterog\u00e9nea, flores que no abren al mismo<br>tiempo, polinizaci\u00f3n deficiente, calibres inconsistentes y porcentaje de fruta exportable que<br>cae.<\/p><p><br>El cambio clim\u00e1tico est\u00e1 haciendo los inviernos m\u00e1s c\u00e1lidos en las zonas productoras de<br>Chile y M\u00e9xico. Las regiones que hist\u00f3ricamente acumulaban horas fr\u00edo con holgura est\u00e1n<br>empezando a quedar en zona de riesgo en algunos a\u00f1os. Y cuando el invierno fue<br>insuficiente, lo que se pierda en primavera ya no tiene recuperaci\u00f3n.<\/p><p><br>Los meteor\u00f3logos expertos de Globalmet monitorean la acumulaci\u00f3n de horas fr\u00edo desde el<br>inicio del invierno, entregando reportes semanales por cuartel del predio a trav\u00e9s de la<br>plataforma de la estaci\u00f3n meteorol\u00f3gica agr\u00edcola. No se usa el dato de la estaci\u00f3n p\u00fablica<br>m\u00e1s cercana. Se usa el dato del sensor de temperatura instalado en el propio huerto,<br>porque en topograf\u00edas con valles, laderas y exposiciones distintas, la acumulaci\u00f3n de fr\u00edo<br>puede variar entre 10% y 25% en distancias de apenas 500 metros.<\/p><p><br>Con ese dato en la mano, el productor puede tomar decisiones concretas: evaluar si aplica<br>inducci\u00f3n qu\u00edmica para complementar el fr\u00edo faltante, definir qu\u00e9 cuarteles entran primero a<br>la poda, anticipar el inicio de floraci\u00f3n para coordinar la polinizaci\u00f3n, y ajustar las<br>aplicaciones de calor artificial si cuenta con sistemas anti-helada que tambi\u00e9n funcionan en<br>sentido contrario.<\/p><p><br>El monitoreo clim\u00e1tico agr\u00edcola de Globalmet incluye una proyecci\u00f3n semanal de<br>acumulaci\u00f3n de horas fr\u00edo basada en el pron\u00f3stico meteorol\u00f3gico de los pr\u00f3ximos 10 d\u00edas,<br>lo que permite actuar con anticipaci\u00f3n en lugar de reaccionar cuando el d\u00e9ficit ya es<br>irreversible.<\/p><p><br>En fruticultura moderna, el que conoce sus horas fr\u00edo toma mejores decisiones. El que las<br>desconoce, apuesta.<\/p>\n<p><!-- \/wp:paragraph --><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Horas fr\u00edo acumuladas: el n\u00famero que m\u00e1s define tu temporada<\/p>","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[],"class_list":["post-6000","post","type-post","status-publish","format-standard","hentry","category-nuestras-experiencias"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8.1 -
