桐生砂是一种火山沙，以产地日本桐生命名，含有大量的三氧化二铁，质量较重（比赤玉土重），颜色是黄色带红的，呈硬石沙状，用来铺面也不错。虽然桐生砂带砂字，但和河沙有所区别，手捏的话表层也会有些土屑剥落，毕竟是火山产的，不像河沙长期经过水流清洗。
　　桐生砂性质上会更像土而不像砂，在所有日系颗粒土中，有最硬之称（相比赤玉土、鹿沼土来说，但实际也不会很硬…），因此也有些人推崇桐生砂，但感觉只是因为它比较硬的关系…当初联萌大叔也是因为这理由有买过，但实际上硬捏的话，还是会剥离一些土屑
 
　　此外因为桐生砂较硬不易粉碎的特性，适合不喜欢换盆和不用换盆的多肉，和其他颗粒土混合可以提高栽培土的排水性，如赤玉土、鹿沼土。说来说去好像硬是唯一亮点...
　　另外还有比较奇怪的一点，虽然桐生砂跟赤玉土之类的同产于火山，但桐生砂整包过来的时候是含有水气的...而赤玉土之类的则很干燥，因此刚开始受到的桐生砂可能偏湿黄色，打开后干了则有点泛白.

1. Water retention: The water retention capacity is quite good, and the red jade soil can keep the water inside the particles. The larger the particles, the better the ability to maintain moisture.
 
 
2. Root affinity: Red jade soil has moderate hardness, which is suitable for succulent rooting. The succulent root system cultivated by the red jade soil is clean and strong. After planting with pure red jade soil for a period of time, each grain of red jade soil will be grasped by the root system.
 
3. Nutrients: In addition to nitrogen and phosphate fertilizers, red jade soil almost contains other trace elements needed for meat.
 
4. Acidity and alkalinity: Red jade soil is weakly acidic, and the PH value is basically neutral, which is not enough for fleshy, because fleshy likes more acidic.

Kiryu sand is a kind of volcanic sand, named after the place of origin, Tongsheng, Japan. It contains a large amount of ferric oxide. It is heavier (heavier than red jade soil), and its color is yellowish red. It is in the shape of hard rock sand. It is also good for paving. . Although the Kiryu sand belt has sand characters, it is different from river sand. If you pinch it with your hands, some soil debris will peel off on the surface. After all, it is produced by a volcano, unlike river sand that has been washed by water for a long time.
 
Kiryu sand is more like soil than sand in nature. Among all Japanese granular soils, it is known as the hardest (compared to red jade soil and Kanuma soil, but it is actually not very hard...), so some people I admire Kiryu sand, but I feel that it is only because of its relatively hard relationship... At the beginning, Uncle Lianmeng also bought it for this reason, but in fact, if it is squeezed hard, it will still peel off some soil crumbs
