\"Humic<\/p>\n

O efeito do \u00e1cido h\u00famico sobre o crescimento das plantas \u00e9 bastante \u00f3bvio. Deixe-me contar-lhe detalhes. J\u00e1 no s\u00e9culo XIX, a import\u00e2ncia de \u00c1cido h\u00famico<\/a> no solo para o crescimento das plantas foi reconhecido de uma perspectiva nutricional.<\/p>\n

Mais tarde, foi relatado que o \u00e1cido h\u00famico pode promover o crescimento das plantas na concentra\u00e7\u00e3o apropriada. Descobrimos que adicionar uma pequena quantidade de \u00e1cido h\u00famico no meio da parede de \u00e1gua poderia aumentar o comprimento da raiz do milho em 500%. E o peso seco e o peso fresco das ra\u00edzes tamb\u00e9m aumentaram significativamente. Os resultados mostraram que o \u00e1cido h\u00famico promoveu significativamente a taxa de crescimento mensal, a altura e o rendimento total de mat\u00e9ria seca das mudas.<\/p>\n

Experimentos de \u00e1cido h\u00famico no crescimento de plantas<\/h2>\n

Al\u00e9m disso, o crescimento de mudas de trigo, tomate e algod\u00e3o, especialmente as ra\u00edzes, foi significativamente promovido pelo \u00e1cido h\u00famico. O \u00e1cido f\u00falvico promoveu significativamente o crescimento das mudas de pepino. O n\u00famero de folhas e flores por planta. Spraying \u00c1cido fulvico<\/a> em mudas de trigo cultivadas em vaso ou campo pode aumentar o rendimento em 7,3 – 18,0%. Mas tamb\u00e9m n\u00e3o pode reduzir o rendimento em condi\u00e7\u00f5es de seca. Alcan\u00e7ando 97% da quantidade normal de regagem.<\/p>\n

O efeito do \u00e1cido h\u00famico no crescimento das plantas foi provado por muitos experimentos. No entanto, devido a diferentes esp\u00e9cies de plantas e diferentes condi\u00e7\u00f5es de cultura. Os n\u00fameros relatados variam muito. O \u00e1cido f\u00falvico aumentou o comprimento da raiz do tomate em 10%. peso fresco em 245% e peso seco em 390%, respectivamente. Geralmente, o \u00e1cido h\u00famico tem mais efeito estimulante nas ra\u00edzes do que em caules e folhas.<\/p>\n

Em alguns casos, para algumas plantas, ele apenas estimula o crescimento das ra\u00edzes, mas tamb\u00e9m da parte do solo. De acordo com a sensibilidade das culturas para a estimula\u00e7\u00e3o do \u00e1cido h\u00famico. As colheitas s\u00e3o divididas nos seguintes tipos. As culturas mais sens\u00edveis – repolho, rabanete, tomate, batata-doce, mel\u00e3o, beterraba, etc. Culturas m\u00e9dias de rea\u00e7\u00e3o – algod\u00e3o, feij\u00e3o verde, feij\u00e3o e assim por diante. Culturas insens\u00edveis – girassol, colza, r\u00edcino, linho e assim por diante.<\/p>\n

Fatores que influenciam os resultados dos experimentos<\/h3>\n

A influ\u00eancia das condi\u00e7\u00f5es de cultura nos resultados dos testes n\u00e3o pode ser ignorada. Porque algumas das experi\u00eancias foram realizadas no campo. Os fatores no solo eram muito complicados. E foi mais dif\u00edcil de repetir em compara\u00e7\u00e3o com as condi\u00e7\u00f5es claras no laborat\u00f3rio.<\/p>\n

A vantagem foi o alto valor de aplica\u00e7\u00e3o. Mesmo no laborat\u00f3rio, com solu\u00e7\u00f5es de nutrientes, h\u00e1 uma s\u00e9rie de fatores. A composi\u00e7\u00e3o da solu\u00e7\u00e3o de nutrientes \u00e9 muito importante. Existem muitos tipos de solu\u00e7\u00f5es de nutrientes para o crescimento global das plantas.<\/p>\n

E as propor\u00e7\u00f5es de v\u00e1rios componentes em diferentes solu\u00e7\u00f5es de nutrientes s\u00e3o diferentes. O que tem diferentes influ\u00eancias sobre o crescimento das plantas. Em segundo lugar, a intera\u00e7\u00e3o de v\u00e1rios componentes na solu\u00e7\u00e3o de nutrientes pode levar \u00e0 produ\u00e7\u00e3o de precipita\u00e7\u00e3o e levar \u00e0 defici\u00eancia desses elementos.<\/p>\n","protected":false},"excerpt":{"rendered":"
