glass slide perspective basin soil dry-wet method

Orchid farmers all know that looking at the degree of dryness and wetness of the potted soil is the basis for deciding whether or not to water the orchid. If you find that the surface of the potted soil is white, you can water the orchid. This is the general knowledge and experience of watering orchids. The watering of orchids is directly related to the success or failure of orchid cultivation and has always been valued by orchids.

As the saying goes, "you can grow orchids and water them for three years." This shows that watering orchids is not an easy task, but it is by no means difficult. Orchids can really become the water of orchid life as long as they scientifically master watering time, watering methods, watering principles and appropriate watering of orchids.

As we all know, the watering of orchids should be determined according to many factors. On this point, Mr. Guan Qingping of Sichuan made a scientific and detailed exposition on the watering of orchids in the article "Orchid World (3)", No. 3, 2004: "the watering times and water requirements of various orchids should be determined according to the growth and environment of orchids. For example, you should take into account complex factors such as orchid varieties, the number of orchid plants, the intensity of light, the placement of orchid pots, the temperature, seasonal changes, ventilation, the thickness of plant materials, the orientation of pots, the size of pots, and so on, and then make a watering decision. this is the knowledge and principle of watering. "

The topic that the author talks about today is to look at the dry and wet condition of the potted soil, but not the watering knowledge of orchids. For this reason, the author used a quick and simple slide perspective method this year to directly see the dry and wet degree of the basin soil matrix, which has a good effect on watering orchids.

Slide perspective was associated with me when I went fishing in the reservoir with several fishing friends. At that time, we were fishing in the reservoir and waited for a long time. We didn't see any change floating in the water, and we didn't catch a single small fish. At this time, a fishing friend sighed, as if talking to himself, but also like saying to me, "Oh!" If you can see the fish in the water and catch the bait directly into the school of fish, you will definitely catch a lot of fish and make sure that you will not go barefoot. "

The speaker is unintentional, the listener is intentional, and the author suddenly thinks of the watering of orchids. It would be nice if we could directly see the degree of dryness and wetness of the upper, middle and lower substrates of the basin soil. Since then, I have been thinking about this problem, thinking and thinking, and finally came up with a way to see through the dry and wet soil with glass slides. The method is: with a round plastic basin, at the neck and bottom of the basin, draw a 4 cm wide rectangle up and down, then at the corner of the rectangle, burn the 1 cm long opening with an electric soldering iron, and then use a hacksaw along the rectangular line, saw the basin wall inside the rectangle, and then use a 5 cm wide rectangular slide to insert directly into the basin bottom from the basin. In this way, the degree of dryness and wetness of the upper, middle and lower layers of the basin soil can be seen directly and clearly through the slides. at the same time, the flow direction and size of the watering can be clearly seen.

Through practice, the author can observe and grasp the dry and wet degree of the basin soil at any time, so that the orchid can be watered at the right time, so as to keep the basin soil matrix "moist but not wet". At the same time, the phenomenon of false water penetration is effectively solved.

Although this method is clumsy and arouses the jokes of orchid friends, it is practical, which is undoubtedly good for beginners who have not mastered the watering technology of orchids. It provides a convenient and accurate basis for watering orchids.

Finally, the author said that if the orchids cultivated on the balcony, the size of the orchid pot is the same, the basin soil matrix is the same, only such an orchid basin will be reformed, and there is no need to do so for all orchid pots. The author introduces this idea, orchid enthusiasts might as well have a try, in practice will know good and bad.
