SU1253463A1 - Method of application of fertilizers to soil - Google Patents

Description

The invention relates to agriculture and can be used for subsoil fertilization in the cultivation of agricultural crops.

The purpose of the invention is to increase the efficiency of fertilizer use by increasing the degree of uniformity of its application to the soil.

FIG. 1 shows an embodiment of the method; in fig. 2 is a diagram of a complete set of mechanisms for implementing the method; in fig. 3 - tukovyshayuschy apparatus with a complete set of mechanisms according to Fig, 2; in fig. 4 — working body (opener) for cutting and fertilizing into an inclined slot; in fig. 5 is the same for cutting and fertilizing in a horizontal slot, top view.

The method is carried out on the arable layer of the soil 1 to its base 2, where the ribbons with horizontal parallel rows of fertilizers 3 are inclined to the horizon and the ribbons with horizontal parallel rows of 4 fertilizers with the same inclination to the horizon. Above the cross-strips of horizontal rows 3 and 4 in the form of a horizontal screen below the surface of the arable layer 1 there are horizontal rows of 5 fertilizers. The mechanism complex includes right-sided and left-sided oblique coulters 6 and left-side 7 and horizontal pointed coulters 8, which, with their uprights 9, are fixed in staggered order on the frame 10 of the metering unit with hoppers II for fertilizers and the corresponding drums 12. the plates 13 mounted outside or inside in their slot-hole nozzles, and the pointed openers 8 are fitted with wedges 14,

The method is carried out as follows.

In the arable layer 1, slots in the longitudinal-vertical plane are cut over its sole 2 and the fertilizers are distributed in them by horizontal parallel rows 3. Then the second slopes in the longitudinal-vertical plane are cross-cut and the fertilizers are distributed in them in the same way. horizontal parallel rows 4, above rows 3 and 4 fertilizers are cut

the horizontal slot and the fertilizers are distributed therein in horizontal parallel rows 5 in the form of a screen grid.

Using the complex, the mechanism method is carried out as follows.

Agricultural aggregate tukovysevayuschy apparatus displayed on the arable field 1. When the unit moves, coulters 6 and 7 and coulters 8 are buried in the arable layer of soil 1, dispensers 12 in racks 9, which are tukoprovoda, from silos 1I dispense granular fertilizers entering the coulters 6-8. Right slotted coulters 6 cut in soil 1 sloping at acute angles to the horizontal transverse plane of the slit and disperse fertilizers with their nozzles in the form of ribbons inclined to the horizontal transverse plane of the belt, which, coming out of the openers nozzles 7, form transverse plates 13 into the horizontal Fertilizer rows of 3 fertilizers. The left flat-opener coulters 7 cut the slopes inclined at an acute angle to the horizontal-transverse plane of the slit cross coulters 6 and fertilizers are sown in the same way in the form of horizontal parallel rows 4. The coulters 6 and 7 of their top are followed by lance coulters. 8, which cut into the soil 1 horizontal slits, and coming into the openers 8

fertilizers flow around them wedge 14 1

and exit into this slot in the form of horizontal parallel rows 5,

Thus, when the sowing apparatus passes in the topsoil of soil 1, fertilizers are laid in the form of inclined cross bands of fertilizers, in which the fertilizers are arranged in the form of horizontal parallel rows 3 and 4, and above them in the form of a horizontal screen in the form of fertilizer, also in the form of parallel horizontal p - is 5,

The horizontal upper rows of 5 fertilizers are buried under the surface of the arable layer 1 to a depth of 5-7 cm, and rows 3 and 4 of fertilizers are below the rows 5 by 5-7 cm with their depth with some gap with the sole 2 of the arable layer 1 to 5-7 cm. Thus,

in arable layer 1, a multilayer cake is obtained: 5-7 cm of topsoil, then a mesh screen from horizontal parallel rows of 5 fertilizers, then again 5-7 cm of soil, then 8-15 cm in height, cross-inclined ribbons of parallel horizontal rows 3 and 4 and again 5-7 cm of soil to the sole 2. This ensures the full depth of the uniform distribution of the traditional fertilizers

plowing by 25-30 cm. In this case, the distance between rows 5 and 3 and 4 between themselves and the horizontal distances between rows are made equal to 5 5-7 cm, which ensures uniform distribution of fertilizers in any cross-section of arable layer I. The present distance parameters are determined by the effectiveness of the interactions of the plant root system with fertilizers up to 2-3 cm.

FERTILIZER METHOD IN SOIL, which includes cutting slots in the soil that are inclined in the longitudinally vertical plane and distributing fertilizers in them in horizontal parallel rows, characterized in that, in order to increase the efficiency of fertilizer use by increasing the uniformity of applying them to the soil, additionally cut inclined in the longitudinally vertical planes of inclined slots, which are located crosswise to the main inclined slots and distribute fertilizers in them in horizontal parallel rows, while above the inclined slots lyami cut a horizontal slit and distribute it in parallel rows fertilizer.
