wild strawberry, raspberry, black currant, growth, efficiency, structure of the plantations, the mechanized cleaning of berries of currant, production efficiency of berries


Work is devoted to problems of increase of efficiency of wild strawberry, a raspberry and a black currant by perfection of structure and care of plantations.

As a result of the carried out researches key parameters of structure of plantations and principles of improvement of a mineral feed of raspberry in intensive culture have been given reason. The optimum maintenance of nutritious elements in leaves of wild strawberry, raspberry and black currant is established. Developed on the basis of sheet and soil diagnostics methods will allow to improve a mineral feed of plants by applying scientifically proved dozes of fertilizers.

Ways of preparation of plantations of black currant with the mechanized cleaning berries are given reason and offered and optimum parameters of these plantations are established. Carrying out planimetric scraps of bushes by preparation of plantations for the mechanized cleaning berries allows lowering industrial expenses for 61-65 %, especially manual skills at cleaning berries and allows mechanizing the basic processes of technology of cultivation of this culture.

Ways of care by plantations of wild strawberry by mulching with polyethylene film of soil in a number are developed and given reason. Application of mulching of soil ground raises the productivity of fruits on 15-25 % in comparison with usual technology, and the received berries are much larger. Besides they are pure from pollution.

Optimum terms of economic operation of intensive plantations of wild strawberry, raspberry and black currant are established and given reason. Reduction of term of operation of plantations for 1-2 years allows raising profit so also profitability of manufacture and more effectively to use soil.

On the basis of the received data and their generalizations are established parameters of structure of intensive plantations for reception of planned crops of fruits. Use of grades of intensive type with the offered parameters of plantations allow on soil with an average level of maintenance of nutritious elements to receive annually up to 25 t/hectare of berries of wild strawberry and on 8 t/hectare of a raspberry and black currant.

Recommendations for productions are included in «Republican standards» and «Recommendations for cultivation of berry cultures in Moldova» and the textbook "Fruit growing" for students of the State Agrarian University of Moldova. Results of research also are used at reading rates "fruit growing" and «berry cultures» for agronomical specialities, performance of course and degree works.
