Provoking the germination of fallen seeds with spring-finger harrows - an important agronomic method of agrophytocenosis weed control

The purpose of the research is to investigate quality spring-finger harrow surface tillage provoke germination carrion depending on angle fingers. Research methods: theoretical – analysis information resources and results spring harrows; laboratory-field economic tests machine with planning experiment, fixing agrotechnical indicators; instrumental measurements; mathematical statistical processing obtained indicators expert evaluation. Results. Experimental field studies a were carried out in order emergence winter rapeseed. It was found that loosens mulches top layer soil well, creating optimal conditions for weeds weed seeds. importance measure litter management prospects use harrows system soil-protective agriculture analytically substantiated. Conclusions. physical parameters as result researches testify at speed about 20 km / h increase an inclination fingers depth their course increases 1,6 times from 7,2 cm 11,3 corresponds agricultural requirements (4-12 cm). crushing terms agronomically valuable aggregates up 0-25 mm size satisfactory excellent values increasing experimental show heavy Degelman Strawmaster SM 7000-50, presence freshly cut rapeseed stubble large clumps chaff, provides tillage, promoting seeds improving phytosanitary future operations.
