ABSTRACT:
A heat transfer tube extends along the peak of a dike having at least two rows of seedlings for collecting heat from the sun during the daytime and transferring the collected heat to the soil at night. The tube is of a geometrical configuration, preferably oval, and is made of transparent plastic. The tube is secured or in intimate contact on opposite sides to a mulching sheet made of opaque plastic, preferably black plastic during the winter growing season, and white plastic during the summer growing season. Optionally, a drip irrigation line is formed separately from or integrally with the heat transfer tube to irrigate the at least two rows of seedlings located on the peak of a dike.
