The reason why the leaves of Brazilian wood are gone
Brazilian wood is a popular leaf-viewing plant, and its unique gold-rimmed stripes on its leaves are the main ornamental feature. However, many flower lovers have found that leaf stripes gradually fade or even disappear during the maintenance process, which hides the dual factors of variety characteristics and maintenance skills. This article will analyze the three main reasons for the disappearance of stripes and corresponding solutions from a professional perspective. There are two main Brazilian wood strains in the market: all-green variety and striped variety. The all-green variety has completely emerald green leaves, a genetic trait unrelated to conservation. If the newly purchased plant has no stripes, it is recommended to check the voucher to confirm the variety. Selection can be distinguished by observing the characteristics of new leaves: striped varieties with light stripes at the base of young leaves. Light imbalance has dual effects on light intensity and directly affects chlorophyll and spot color development: 1. Light-deficient environment (<800lux): Leaf synthesis of excessive chlorophyll causes mottled patterns to be covered with green 2. Direct light (>15000lux): Ultraviolet light suppresses the synthesis of stain pigments. It is recommended to use a luminometer to monitor it. Maintain a scattered light environment of 2000- 8,000 lux. In summer, light quality and duration need to be blocked by 60% light quality and blue and violet light to promote stripe color development. It is recommended to ensure 4 hours of illumination in the 450nm band every day. Full-spectrum plant fill light can be used to assist, and the fill light time in winter can be extended to 8-10 hours. Pay attention to avoid supplementary light at night affecting plant photoperiod. The stripe restoration and maintenance plan implements the "light and fertilizer collaborative management method":·Apply leaf viewing plant nutrient solution containing magnesium and manganese elements (N-P-K=3-1-2) every month·Combine with 0.1% ferrous sulfate solution to irrigate the roots every quarter·Rotate flower pots to ensure uniform light on both sides Practice shows that after 2-3 months of scientific maintenance, the recovery rate of new leaf markings can reach more than 75%.
Through gene confirmation, light environment optimization and three-dimensional control of nutrient management, it can not only maintain the ornamental nature of existing leaves, but also promote the development of new leaf markings. It is recommended to take leaf comparison maps every quarter and establish a visual file of maintenance effects.
