A machine that sown with precise seeding, plant spacing and depth. It has the advantages of saving seeds, eliminating the seedling operation after emergence, and making the nutrient area of each crop uniform. It is mostly a single-hole sowing and precise control of the multi-hole seeding of the number of grains per hole. It is generally improved on the basis of various types of seeding machines. For example, to improve the shape and size of the hole type on the hole wheel seed meter, so that it only accepts one seed and prevents holes; directly connect the seed meter to the opener or place it in the opener to reduce the seeding height. Control seed drop speed to avoid seed bounce; install vertical disc seeder on horizontal disc seeder to change seeding direction and reduce seeding height to avoid seed displacement; double disc trenching A co-position limited depth wheel is attached to the machine to ensure stable seeding depth. The multi-grain precision seeding machine adds a cavitating mechanism between the seed metering device and the opener, so that the single seeds discharged by the seed metering device are collected into a precise number of seed groups in the caulking mechanism, and then planted into the seed furrow. In addition, new structures have been developed, such as seeding with a paper strip that has been fixed at a certain spacing in advance, or by arranging seeds from a circular rubber or plastic seed hole that is vertically rotated into a seed groove.
