Bazele ştiinţifice ale sporirii productivităţii mărului în sistemul superintensiv de cultură

Abstract

In the polyfactorial experiences with apple trees varieties Gala Must, Idared, Golden Delicious, Ionagored etc., there have been analyzed the main indices of the vegetal environment, mineral nutrition, photosynthesis productivity and water consumption in the nursery and orchard. Also, there have been established the optimization principles and norms regarding: plantation structure as a photosynthetic system of production, fertilization and irrigation system under planned yield, fruits load regulation and others. As a result, the methodology of quantity, quality and higher competitiveness of the productivity planning in different culture conditions has been elaborated: 29-31 thousand fruit trees with a standard crown form in the 2nd field of nursery, till 40-50 t/ha of high quality fruits.
