Performance evaluation of 8-row power operated rice transplanter.

摘要

The performance evaluation of an 8-row power operated rice transplanter under varying nursery rice mat densities revealed that the density should be between 0.4 and 0.6 kg/m2 to obtain the optimum seedling rate of 3-4 plants per hill (66-79% of hills had 1-5 seedlings, and 51-69% had 2-5) and to reduce the number of missing hills to a minimum (<13%). Each picker on the transplanter picks up an area of 1.5 cm2 of mat, hence the distribution of seeds in the mat should be 3 seeds cm-2 when sowing, a sowing density of 0.41 kg/m2.
