Falsa Acácia, nome científico: Robinia Pseudoacacia. É da família das leguminosas e quase como todas os membros desta absorve o azoto do ar e incorpora-o no solo, melhorando-o. Estas plantas são até chamadas de melhoradoras ou de suporte e os frutos têm a forma de vagem como as ervilhas, favas e feijão (também desta família).
No planeamento de uma agrofloresta são de extrema importância e inicialmente deverão constituir 80 a 90% das espécies plantadas. Nos climas tropicais existem várias espécies mas em Portugal, em forma de árvore, apenas me lembro da Alfarrobeira que tenho sérias dúvidas que se estabeleça por aqui. (Há que tentar). Daí utilizarem muito por cá espécies de crescimento rápido para criação de biomassa que é depois cortada e colocada no solo mas que não têm a capacidade de fixar azoto: choupos, eucaliptos e até bananeiras.
Eu inclui esta espécie na lista constituinte da minha agrofloresta e outras suas parentes como o Espinheiro da Virgínia ou a Albizia Julibrissin (sem nome português). Estas espécies são difíceis de encontrar. Não as têm em viveiros e na net ainda são caras.
Há pouco tempo apercebi-me que a árvore que têm no pátio da padaria (onde vou buscar a minha correspondência) é uma Albizia. Quem diria. Com a tentativa de estaquias falhada estou agora a aguardar que as vagens sequem. E há dias, enquanto procurava pelo Zezinho, encontrei uma Falsa Acácia, também no pequeno Terreiro das Bruxas. Já com as vagens secas, trouxe algumas e segundo a minha bíblia das plantas (pfaf) coloquei as sementes em água 48h antes de as semear. Não é que apenas passadas 8 horas, as sementes já germinaram na água?! Esta árvore está deserta para salvar o mundo e eu vou apenas ser a via.
Aquela deixa que: "Quando olhamos em nosso redor encontramos tudo o que precisamos", não podia ser tão verdade.
Afinal as sementes não estavam a germinar. Os cordões umbilicais que ligam as sementes às vagens é que incharam na água e deram-me essa sensação. Mas eu gosto do texto na mesma :)
A Falsa Acácia à beira da estrada - The Black Locust next to the road
Black Locust, scientific name: Robinia Pseudoacacia. It's from the family of legumes and almost like all the members, absorbs nitrogen from the air and incorporates it into the soil, improving it. These plants are even called enhancers or support ones and the fruits are shaped like pods such as peas and beans (also from this family).
In the planning of an agroforestry they're of extreme importance and initially they should constitute 80 to 90% of the species planted. In tropical climates there are several species but in Portugal, tree-shaped, I only remember Carob that I have serious doubts that it establishes here. (Must try). Instead they use very fast growing species for biomass that are then cut and placed in the soil but don't have the capacity to fix nitrogen: poplars, eucalyptus and even banana trees.
I include this species in the list of my agroforest and other relatives such as Honey Locust or Silktree. These species are hard to find. There aren't in nurseries and on internet they are expensive.
Not long ago I realized that the tree they have in the courtyard of the bakery (where I go to get my mail) is a Silktree. Who would say. With the attempt of cuttings failed, I'm now waiting for the pods to dry. And some days ago, while I was searching for Zezinho, I found a Black Locust, also in the little Terreiro das Bruxas (this settelment). Already with the dried pods, I brought some and according to my bible of plants (pfaf) I put the seeds in water 48h before sowing them. Isn't that just past 8 hours, the seeds have already germinated in the water?! This tree is deserted to save the world and I will only be the way to.
That statment: "When we look around we find everything we need," couldn't be so true.
After all the seeds weren't germinating. The umbilical cords that attach the seeds to the pods are what swelled in the water and gave me that feeling. But I like the text anyway :)
