Low order tillering growth accelerant for rice in cold region

A cold area rice low tiller growth promotion agent belongs to the plant nutrition filed. The agent consists of cane sugar, carbonamides, methionine, phenylalanine and aspartic acid, auxiliary agents and water. The agent is directly supplemented through leaves to compensate heat restraint of rice rootage and tiller in the northern cold area and keep seedling leaves to have physiology and produce physiological power of the seedling low tiller and growth. Seedbed leaves are sprayed two days before transplanting the rice seedling. The dose is 6-10ml per 10 square meter. After test, rejuvenation period is 3-4 days and is shortened to be a half.
