PROBLEM TO BE SOLVED: To provide a method for cultivating farm crops, (1) capable of solving the problems of the badness of the taking root of a seedling, and the badness of initial growth caused by low temperature, (2) capable of making ventilation operation unnecessary, (3) capable of preventing the temperature from being lowered by the blowing in of wind to solve the problem of crops and materials being made dirty by the blowing in of sand and dust, (4) capable of forming the good growing environment with an adequate humidity, and (5) hardly causing the problems of low temperature injury in nighttime and high temperature injury in daytime. SOLUTION: This method for cultivating the farm crops by installing at least one line of tunnels 2a and 2b covered with a film 2A for the tunnel in a plastic green house for agriculture or in a large-scale tunnel, further installing a mulching film 3 for covering a ridge surface in the tunnels 2a and 2b, and forming a nonwoven fabric 4 for covering the cultivated crops 5 at the upper part of the mulching film 3 is characterized in that the film 2A for the tunnel has a plurality of ventilation holes 20 regulated so that the numerical aperture of the film 2A may be 0.4-6.0%, and the nonwoven fabric 4 is a nonwoven fabric of a split fiber composed of a polyvinyl alcoholic synthetic resin. |
