The researches of broomrape acclimatization on white cabbage in the soil-climatic conditions of Central region of the Russian Federation
Abstract
Relevance. In one of the farms, situated in the Central region of the Russian Federation was found the first defeat of cabbage by obligate weed – broomrape. As the long experience shows (since 2011 yr.), the control of broomrape is very difficult, and it is a real danger for the vegetable growing in this region.Materials and methods. The object of researches were the plantations of white cabbage, which was grown by using the cassette technology, there were field experiments.The research methods included the following works: phenological observations of broomrape and white cabbage ontogenesis, the detection of the main features during blooming and fruiting of this weed, the definition of the duration of broomrape evolution until the fruiting phase, the detection of blooming shoots location on the surface of the cabbage plantation, the identifying of relationship between the height of broomrape’s flower-bearing shoots and the height of leaves of cabbage’s rosette.There was analyzed the feature of growing by using the cassette technology cabbage, being damaged by broomrape.Results. It was found, that the studied in the paper race of broomrape can successfully progress in more northern soil-climatic conditions of the Central region of the Russian Federation. The complex of agro technical methods of broomrape control is suggested, it includes: the two-level plowing of the weedy fields right after harvesting cabbage; receiving of cabbage’s fibrous root, which should be situated into the working plowing space with depth up to 25 cm; multiplex cultivation of the growing shoots of the weed; the cabbage hilling before rows closing. The alternative methods of broomrape control also can be used: the conveyer of cruciferous vegetable cultures with short vegetation period and cultures, which provoke the germination of the weed.
