METHOD FOR PRODUCING OF GREEN FEED DURING CULTIVATION IN IRRIGATED AGRICULTURE, AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2006 - IPC A01B79/02 A23K3/00 

FIELD: agriculture, in particular, feed production under arid zone irrigation conditions, and agricultural engineering.

SUBSTANCE: method involves sowing seeds of fodder crops having different growing period times from sowing to harvesting of yield; providing alternate mowing of said crops by means of feed harvesting machines for green mass; beginning sowing procedure on one plot with annular grasses in winter, early spring and late autumn; then cultivating double and triple mixtures on plots which became free, said mixtures consisting of early mown and late mown crops, late summer and heat-loving stubble crops of second yield; cultivating on plots which became free of frost-resistant crops of third yield from mixture of cereals and cruciferous crops. During mowing on green mass of annular grass in winter, early spring and late autumn crops, 15-30%-solution of natural bischofite is applied to each ton of green mass, said solution being utilized as preservative at the rate of 12-14 g per 1 kg of green mass. Brine of natural bischofite is applied onto surface of stubble of mown mass at density of 1.2-1.3 t/m³ with norm of 8.0-15.0 g/m². On mowing heat-loving crops of second yield for green mass, 25-45%-solution of natural bischofile is applied at the rate of 18-26 g per 1 kg of green mass, and on mowing of third yield comprising mixture of cereals and cruciferous crops, 40-60%-solution of natural bischofite is applied at the rate of 30-38 g per 1 kg of green ground mass. Apparatus for applying into feed of liquid preservatives in the form of solution of natural bischofite has reservoir for preservative equipped with hydraulic mixer and taking-in conduit furnished with cut extending in plane arranged at an angle to axis of conduit, hydraulic pump positioned downstream of reservoir, and intermediate tank provided with one inlet branch pipe and two outlet branch pipes and connected to tank through pneumatic pump. One of tank outlet branch pipes is communicating with reservoir and other outlet branch pipe is communicating through two-way valve with actuating mechanism. Inlet branch pipe is positioned in lower part of tank, tangentially to its side wall. Hydraulic mixer is positioned in reservoir and communicating with outlet branch pipe of tank. Two-way valve is connected through actuating mechanism for feeding of preservative with nozzles positioned in silage guide of said machine, wherein feed mass sensor is positioned. Apparatus is equipped with additional reservoir for preservative, sprayer boom, and pair of three-way valves.

EFFECT: enhanced reliability in operation and improved quality of green feed.
