    Default Info on anthurium flower

    Hi

    I am very much interested to know how anthurium flower's grown in less than one hectare which is located near Bidadi small village called "Annahalli" . And it is a wet land. For more information you can reply or can call me . And speek with Rajashekaraiah Or Shivananda.

    HI

    the various cultivation practices for growing anthurium are discussed here.

    A. Greenhouse Cultivation
    Construction of suitable greenhouse to provide ideal growing environment including light, temperature, etc., is very essential for commercial production of anthuriums. Flower productivity is ideal in a house with whitewash on the roof, roof sprayers and crop sprinklers and movable external screens.

    B. Potting and planting
    Potting is an essential operation for anthuriums. As soon as the seedlings are large enough to handle, when cuttings bears fully developed roots and shoots or offshoots are ready for division, they should be moved into pots. Care should be taken that pots are of suitable sizes. Potting may be done fairly firmly when using loam-based composts, firming with fingers, but peat-based composts should be only lightly firmed and watered to settle the compost. Peat compost should also never be allowed to dry.

    If planting is to be done in beds, plants should properly be spaced. Four plant densities (5.2, 7, 8.7 and 10.5 plants/m2 of bed) were compared by Steen for growing Anthurium andreanum. It has been recorded that the number of flowers/ m2 increased with plant number, this effect being greater in the first year than in the second. However, the productivity per plant declines with increasing plant density. Leaving side shoots on the plants will have a positive effect on the number of flowers/m2, but this effect becomes less pronounced as plant density increased. When all side shoots are removed, plant density does not influence flower diameter but when they were retained increasing density will have a slightly adverse effect on diameter.

    Plants should carefully be examined to decide when repotting is due. The new pots should not be very much larger than the previous ones. Young plants need repotting every year, while the adult once every 2-3 years.

    C. Manuring and fertilization
    Anthuriums need adequate amount of nutrients for their proper growth and flowering. Among the major elements, application of nitrogen potassium and calcium markedly improvc the yield and quality of flowers. Deficiencies of these nutrients, on the other hand, adversely affect the plant growth and developments. Insufficient levels of nitrogen and potassium are associated with lower flower yield, reduces stem length and smaller flowers. Leaf necrosis and dead root tips are observed with deficiency of potassium. Application of 126 mg N/12.5 litre container per week is suggested for Anthurium andreanum. An increase in potassium from mg/container per week to 225 mg improves both flower yield and quality, but a further increase may have a slightly negative effect. The best results can be obtained with an annual dressing of 29 g N + 30 g K2O/m2. At optimum nutrient levels, mature leaves containes 2% nitrogen and 3% potassium. Nitrogen also has a beneficial effect on the quality of potted A. scherzerianum, the best result being obtained with a medium dose of 21. 6 mg N/pot/week. Application of 22.5 mg K/pot/week gives better quality plants.

    Adequate level of calcium is also necessary for obtaining optimum yield and to stabilize spathe colour. Deficiency of calcium resulted in colour break down, instability of the middle lamella and cell separation and collapse in proximal section of the lobe and spathe. The problem is more serious at lower pH of the substrate (3.0 to 4.0). The optimum calcium content in the lobe and leaf tissues have been found to be 0.16 and 0.54%, respectively.

    Plants having the highest fresh and dry weights, the largest number of flowers, the longest stems and the best quality flowers with no leaf chlorosis are observed with 4 g CaCO3 (calcium carbonate) and no boron. However, the longest spadix and flower fresh weight are obtained with 4 g Caco3 and 2.0 mg boron.



    D. Watering of Anthurium
    Anthuriums require generous watering. However, the right amount of water and proper intervals between successive application of water are determined by several factors. Micro- climate in the greenhouse, season, size of the plant in relation to the diameter of the pot, stage of plant growth, type of container and the compost in which the plant is being grown are important. Plentiful watering should be done during spring and summer, and in winter, when the plants are resting the surface soil is to be allowed to dry out between successive watering.

    The quality of water also has considerable influence on plant growth and development. The cut-flower yield of A. andreanum declines progressively as the salinity of the water used for glass house irrigation increases. Water containing! sodium chloride (common salt) is particularly detrimental lowers the production by 40-46 per cent.
