The study was conducted in an organic nursery of sour cherry cultivars ＂Debreceni Botermo＂ and ＂Sabina＂ in the years 2010 and 2011. Cherry trees grafted on Mahaleb （Prunus mahaleb L.） seedlings were grown at a spacing of 25 crn × 1.0 m. In the nursery, an assessment was carried out of the effect of various biopreparations on such growth characteristics as the thickness and height of the maidens, the formation of lateral shoots and the total increase in their length. The control trees were not treated at all, but fertilized with an NPK fertilizer only （second control）. To stimulate growth, use was made of granular manure, mycorrhizal fungi in the form of the preparation Micosat, humic preparations or so-called vermicomposts （Humus UP, Humus Active）, extracts of marine algae （BF Quality） and of terrestrial plants （BF Arnin）, a product derived from yeast （Vinassa） and Tytanit. The specific biological effects of the preparations used in the sour cherry nursery for each morphological feature are presented in this paper in graphical form. A beneficial effect on the increase in the number of lateral shoots and the increase in their length was produced by the use of such products as： Micosat, Humus UP, Humus Active ＋ Aktywit PM and Vinassa. The most effective in this respect was BF Amin.

Effect of Some Bioproducts on Winter Mortality of Grafted Buds and the Number of Maiden Fruit Trees Produced in an Organic Nursery

引用

Journal of Life Sciences 2013年第3期7卷 282-288页

作者： zygmunt stanistaw grzyb wojciech piotrowski pawet bielicki lidia sas paszt Department of Pomology Research Institute of Horticulture

In an organic nursery, various bioproducts were used to stimulate plant growth： Fertigo （granulated bovine manure）, Micosat, Humus UP （humic acids microbiologically enriched）, Humus Active ＋ Aktywit PM （beneficial microorganisms）, BioFeed Amin, BioFeed Quality, Tytanit, and Vinassa. One of the aims of the study was to determine the effect of these products on the ability of grafted buds of apple and sour cherry cultivars to survive the winter. Losses resulting from the freezing of buds during winter dormancy were calculated as the difference between the number of buds deemed to have taken in autumn and the number of live buds that began to develop properly in the spring of the following year. In autumn, the number of maiden trees obtained in each fertilization combination was also determined in the same nursery. The greatest tendency to die in winter was shown by apple and sour cherry buds in those combinations in which the rootstocks were supplied with a mineral fertilizer with NPK components, and the smallest where humic preparations （so-called vermiculites） were used. The type of fertilizer had an indirect influence not only on the number of grafted buds that died in winter as a result of freezing, but also on the final number of maiden trees obtained from a given area of the nursery.
