摘要:
A new apparatus and system for the systematic application of liquid chemicals to plants is disclosed. A soft woven nylon rope wick is used to convey chemical solution from a reservoir by means of capillary action. The rope apparatus, which is physically supported, is leveled and positioned to selectively contact certain plants as the wick is moved across an agricultural field. Thus chemical solution is deposited selectively only on contact with the wick.

An aquatic weed barrier is disclosed which comprises a film having a plurality of incisions therein. Each incision is shaped to form at least one flap adjacent the incision. The film has a light transmittance of less than 50% in the 200 to 650 nm wavelength range.
摘要:
This invention relates to a device for depositing a treatment liquid, such as a weedkiller, on plants, the device comprising a tank for the liquid, a plurality of wicks outside the tank, and elements for transferring the liquid contained in the tank to the ends of the wicks. The tank has a horizontally elongate shape and a cross-section which is very much greater than that of the wicks. The tank forms a ramp integral with a dispensing tube, which is mounted underneath the bottom of the elongate tank, parallel to its longitudinal axis, so that the dispensing tube is fed with liquid from a zone of the tank bottom, preferably adjacent to one of the ends of the tank. The dispensing tube has a cross-section similar to that of each wick, and a plurality of inlets or branches in which the ends of the wicks are immobilized by clamping and sealing devices, so that the remainders of the wicks extend freely outside the dispensing tube and the tank.
摘要:
Liquid applying apparatus mountable on a lawnmower, the apparatus including a liquid storing portion, a liquid distributing portion and a mounting portion; the liquid storing portion including a substantially airtight chamber, an opening adjacent the bottom of the storing chamber, a conduit extending downwardly from the storing chamber opening to the liquid distributing portion, the liquid distributing portion including a substantially horizontal distribution chamber, the distribution chamber including an inlet opening adjacent the top thereof, the inlet opening being connectable with the conduit, a plurality of spaced outlet openings in the distribution chamber, the outlet openings being arranged along at least one substantially horizontal line disposed longitudinally of the distribution chamber and located intermediate the top and bottom of the chamber, the conduit extending through the inlet opening of the distribution chamber to a point adjacent the horizontal line of openings in the chamber, textile material disposed with one end section wrapped around the periphery of the distribution chamber and the opposite end section extending from the wrapped section; the mounting portion including at least one bracket having one end affixable to the distribution chamber, a support extending upwardly from the bracket capable of supporting the liquid storing portion above the distribution chamber.
摘要:
Disclosed is an improved method of inducing lightwood formation in a living conifer. The improved method comprises heating the sapwood of a selected section of a conifer to a temperature of from about 40.degree. C. to about 100.degree. C. by means of an energy source such as radiant energy.
摘要:
An apparatus and process applying herbicide-containing liquid to weeds in a field also containing growing cultivated crops neighboring said weeds comprises means for moving an apparatus that transports a load of herbicide-containing liquid in a reservoir therefor along that field and then distributing that liquid from that reservoir to a weed-contacting surface: the pressure-controlled liquid reservoir provides the herbicide-containing liquid to any array of dispenser units arranged to rapidly and reliably and selectively and efficiently apply such herbicide-bearing liquid to the surface of weed plants in the field projecting above a neighboring cultivated crop without misapplication of such herbicide-containing liquids to such neighboring crops.
摘要:
A portable hand-held herbicide and insecticide applicator is comprised of a hollow tubular frame including a handle section and a pair of extended spaced prong sections, forming a liquid reservoir conduit having spaced discharge ports between which extends an absorptive rope mop in wicking relation with and saturated by liquid in the reservoir conduit.
摘要:
A series of wick ropes are pressure fed with herbicide. They are moved along weeds to be killed at about a 35.degree. angle so that the ropes wipe along the weeds applying herbicide thereto. Each rather short section of rope is fed by a different reservoir so that if the applicator is on a slope as by a roadside, the head upon the ropes at one end is not much greater than upon the other end.

摘要:
The above-ground growth of potatoes and like root crops are contacted with high voltage electricity several days prior to harvesting, the electricity desiccating the above-ground portion of the crops while not harming the tubers. A no-load voltage of about 20 kv with an energy density of about 11-15 kw/foot of width treated is effective. Low-bush blueberries, and like perennial crops, are pruned by contacting the above-ground growth thereof with electricity. Pruning, in the case of blueberries, is most effective when done approximately every other year in the case of blueberries, a no-load voltage of 10-20 kv with an energy density of about 2-3 kw/foot of width treated being effective.
