Deciduous flowering method: Loofah pods are best to smash from the bottom up, and the larvae should not exceed 2/3. Because if you scoop too much, it will not only cause the phenomenon of “melon melon†directly, but also cause the hormone to pass through the roots of the larvae to the whole body of the plant, causing hormonal intoxication; and if the lice are too few, the gourd flower will fall off easily. , melon growth will be inhibited.
Decorating time: Generally from 10am to 1pm (Luffa flower slightly yellow but not green). If the flower is too early, it will linger when there is a bud, and it is easy to have a "dumb" flower; if it is too late, the gourd flower will fall off easily.
Flowering agent concentration: The concentration of anthraquinone agent should not be the same, it should be changed with the change of temperature in the greenhouse. In general, when the temperature in the greenhouse is high, the concentration of the flocculent should be lower; when the temperature is low, the concentration should be higher.
In addition, it is best not to water it for 3 days after flowering. Because the Loofah grows upwards before the flowers are cut, and after the picking, the Loofah grows downwards. If you water directly after flowering, it will make the water in the plant bigger. At this time, Guayin is not completely sitting, and the water suddenly increases, and it is easy to appear the phenomenon of “melon and cucumberâ€.

Natural pigments generally come from natural ingredients, such as beet red, grape and pepper. These foods have been recognized and accepted by the majority of consumers.
