FIELD: agricultural engineering. SUBSTANCE: method implies forming a clamp on prepared site, covering it with thermal insulating material. Ground under clamp base is subjected to freezing in winter period for cold accumulation, and in spring period the clamp site is covered with straw. In summer, layer of straw is removed, green mass of grass is laid on frozen ground in layers alternating with layers of straw. Placed inside green mass of grass are vessels with cooling medium thermally connected with frozen ground. Outer surface of clamp is coated with straw for warmth keeping and covered with film, then it is tightened by plastic strips. In autumn at first frosts, preserved clamp is pulled off its site, and installed on site are cooling units for freezing of ground and accumulation of cold for next year fodder clamp storage. Gaseous preserving agent can be injected into formed clamp. Cooling agent can be introduced into ground prior to its freezing. Freezing of ground and cooling of vessels placed in green mass layers can be effected from artificial source of cold. During fodder storage period, periodic vacuumizing of fodder clamp can be effected. EFFECT: high efficiency. 1 cl, 4 dwg |
