PROBLEM TO BE SOLVED: To provide a foam formation spray for fruit tree bark protection and a fruit tree raising method which give protection against freezing damage, freeze-drying damage, sunburn and insect pests.SOLUTION: A foam formation spray 100 is provided in which injection liquid foams when being injected to expand and solidify. Solidification speed of ingredient of the foam formation spray after being injected on a fruit tree bark is faster than flowing speed thereof on the fruit tree bark so that the ingredient of the foam formation spray solidifies on the bark along the surface shape of the bark to be capable of forming a foam containing coated body for the fruit tree bark. For example, the ingredient of the foam formation spray is a foamed urethane based ingredient. It is possible to blend functional components such as a nutrient component enhancing growth of the fruit tree without an inhibitor component inhibiting growth of the fruit tree, a component evading insect pests, injurious birds and animals while toxicity to the fruit tree is small, and a component absorbing or scattering ultraviolet ray.SELECTED DRAWING: Figure 1 |
