Shallow planting of the rice seedlings is an important factor for getting high yield as it can increase the effective tillers on the lownode of the stem. The 2 ZB-79 shallow rice seedling transplanter combined the advantages of shallow planting of the seedling-casting rice transplanter and orderly planting of the traditional rice transplanter. The principle of this kind of machine is firstly to cut the standardization nursery rice seedlings with rug soil into many small pieces,and then to plant the small pieces composed of pot soil and some seedlings on it to the field surface in order,only shallowly planted on the very top part of paddy soil. Not only it can keep the performance of planting shallowly and orderly,but also simplify many mechanisms for transition,separation,and plantation of rice seedlings. It is a new type of rice seedling transplanter called laying-type up to now to get higher efficiency when working and higher yield for rice production. This paper will introduce its developing results and analyze the comparative experiments.
