Problems solved by technology

[0003] Since Phalaenopsis is a new variety introduced from abroad, it has been introduced in my country not long ago, and there is little research in the field of cultivation technology. Therefore, there are still certain defects in the quality of flowers in our country. Brown spot disease, especially during the "May 1st" and "11th" market, this situation seriously affects the quality of Phalaenopsis and reduces its economic value

example 1

[0008] The test material is 400 phalaenopsis introduced from Holland, divided into two groups of test group and control group, 200 plants in each group. The cultivation medium is mixed with Klasmann640# peat soil imported from Germany and perlite at a volume ratio of 4:1.

[0009] Test group: temperature 25-28°C during the day, 18-20°C at night, humidity 70%-80% during the day, 75%-85% at night, light 10000-12000Lux, spray thiophanate-methyl once a month from the introduction of seedlings Wettable powder 800 times liquid, spray continuously for 5 months, and the time of spraying fertilizer is before the sun shines on the plants in the morning; during this period, water or fertilize as follows: when the EC value of the soil is > 0.4, water the clear water, and the EC value of the soil When the value is less than 0.4, use Huaduoduo 20-10-200.3g per liter of water, Huaduoduo 15-20-25 0.05g, MgSO 4 0.16g solution or 0.8g / L Huaduoduo 20-20-20 water solution for watering alternate...

Abstract

The invention discloses a method for preventing and controlling phalaenopsis amabilis brown spot. The method is characterized by comprising the following steps of: mixing turfy soil and perlite according to a volume ratio of 4:1-5:1 to form a culture substrate, wherein the temperature is between 25 and 28 DEG C in the daytime and is between 18 and 20 DEG C in the evening, the humidity is between 70 and 80 percent in the daytime and is between 75 and 85 percent in the evening, and the illumination is between 10,000 and 12,000Lux; spraying solution formed by dissolving thiophanate methyl wettable powder in 800 to 1,000 times water once every month after seedlings are introduced; continuously spraying for 5 months; and irrigating with water or fertilizer in the following way during the spraying: irrigating with clear water when emission concentration (EC) value of soil is more than 0.4; and irrigating with aqueous solution which is formed by mixing 0.3 to 0.4g of peters product 20-10-200, 0.05 to 0.07g of peters product 15-20-25 and 0.16 to 0.18g of MgSO4 in every liter of water and aqueous solution which is formed by dissolving 0.8 to 0.9g of peters product 20-20-20 in every liter of water in turn when the EC value of the soil is less than 0.4.

Description

technical field [0001] The invention belongs to the field of plant cultivation methods; in particular, the field of Phalaenopsis cultivation methods. Background technique [0002] Phalaenopsis is a crop of the Orchidaceae Phalaenopsis, native to subtropical rainforests. Avoid extreme heat and dryness. In winter, sufficient light is needed, but exposure to the sun will burn the leaves. Phalaenopsis white and thick air roots are exposed around the leaves, which can absorb nutrients in the air. Some climb on the outer wall of the flower pot, which is very natural and wild. In different seasons, the Phalaenopsis plants pull out long flower stalks from the leaf axils, and bloom flowers shaped like flying butterflies, which are favored by flower fans, so they are known as the "Queen of Cattleya". Phalaenopsis likes slightly acidic and loose Porous, well-drained, air-permeable substrate with strong water and fertilizer retention capabilities, the plants are shade-tolerant and heat...
