In article it is a question of creation in modern technologies of cultivation of grain crops of a technological track. It is necessary for performance of agrotechnical receptions on the care of crops, in particular, for processing by herbicides, fungicidami, insecticides, and also at carrying out by land tools of extra root top dressing, a sinikatsiya and other operations.
Crops with a technological track have the following advantages: signallers aren’t required when processing crops; double processings by preparations or flaws are excluded; wheels of tractors and agricultural cars pass on paths without damaging a plant.
Modern technologies of cultivation of grain crops provide creation at crops of a technological track
Modern technologies of cultivation of grain crops provide creation at crops of a technological track. It is necessary for performance of agrotechnical receptions on the care of crops, in particular for processing by herbicides, fungicidami, insecticides, and also at carrying out by land tools of extra root top dressing, a sinikatsiya and other operations.
Crops with a technological track have the advantages. First, signallers aren’t required when processings crops; secondly, double processings by preparations or flaws are excluded; thirdly, wheels of tractors and agricultural cars pass on paths at all without damaging a plant or injuring them in much smaller measure.
The width of a path in a technological track usually makes 30-45 see. For this purpose on a seeder by means of a zaslonka seeding from one or two soshnik for one path is blocked.
Depending on constructive width of capture of cars and tools on the care of crops are created technological a track with a certain distance between them. The width of a sprayer undertakes a basis, as most important and necessary tool, mainly. Sowing units with the corresponding width of capture in this regard steal up. If it is not enough width of capture of one pass of the sowing unit for width of a sprayer, the technological track is created from two passes of units with identical or different working width. At compliance of these parameters the technological track passes on a tractor trace at crops that from the agrotechnical point of view most expediently.
The distance between two paths of a technological track should correspond to distance between centers wheels of a tractor or self-propelled agricultural cars. Usually the track of propashny wheel tractors and the majority of agricultural cars makes 140 see. Proceeding from it, at crops by usual ordinary way with row-spacings of 15 cm the centers of paths should be through 9 row-spacings (10 ryadok). At crops by sternevy seeders with width of row-spacings of 22,5 cm of a path settle down through 6 row-spacings (7 ryadok).
For convenience in using calculations of placement of a technological track for various sowing units are presented in a tabular form.
Note: 1. Numbering of seeders and soshnik is given at the left – to the right on a unit course; 2. Crops begin with the left edge of a field in the shuttle way.
At insignificant deviations of width of a sprayer from the sowing unit it is necessary to block superfluous soshnik or sprays for reduction of their working width of capture in compliance.
