Abstract:
A method for inhibiting bud formation on agriculturally-valuable flora which comprises the step of:pumping a coolant through at least one distribution line of a system which comprises:a) a coolant-bearing subterranean closed-loop conduit having a high-pressure region containing said coolant in the liquid state and a low-pressure region containing said coolant in the gaseous state;b) a compressor having an inlet and an outlet wherein said inlet is in contact with said low-pressure region and said outlet is in contact with said high-pressure region;c) a tank for storage of said liquid coolant;d) at least one distribution line located between said outlet and said inlet of said compressor; ande) at least one throttle having a diameter between about 1/128.sup.th and 1/32.sup.nd of an inch located within said distribution line through which said coolant expands as it passes from said high-pressure region to said low-pressure regionprior to formation of buds on said flora.
