Technical Field

The invention relates to a rice transplanter, and belongs to the technical field of agricultural machinery.

Background

In the planting process of crops, seedling transplanting and film mulching are very important links, and the plastic film mulching can enable soil to fully absorb solar energy, improve the ground temperature, preserve soil moisture and prevent early stage, loosen the soil and promote the conversion of soil nutrients. Light waves emitted from the sun can smoothly pass through the plastic film. The ground radiation light wave is a long wave, and the radiation light wave is not easy to pass through the film and reflect to the atmosphere, so that the solar energy can be converted into heat energy to be reserved in the soil. And because the film has the function of heat preservation, the falling speed of the soil temperature at night is slowed down. This is known as the "greenhouse effect". The farmland mulching film reduces the evaporation of soil moisture and also has the effect of storing water and preserving soil moisture.
