To deepen a root system

 

Rice straw has been used to reduce growth stimulation and a cold drought disaster when I set tea newly, but the use of the polymulti-material increases as rice straw and coating material with the growth stimulation effect with more than of same class while in late years rice straw material is short.
It is said that a growth stimulation effect is high as for the black multi-use to the origin of tea tree strain of the young tree period, and making it it can expect resolution garden already.
 

It is two years from permanent planting
Poly multi-.which I used expecting a growth stimulation effect A root system is apt to become slight when I do not tear this off.
If a root system is slight, it becomes easy to receive winter drought damage.
Because I am said to be 50-60cm, the depth of the root zone necessary to evade drought damage in a tea plantation carries out this activity.
