Features of growing peppermint in the Far East
The Far East has agroclimatic resources for the successful cultivation of peppermint in order to obtain and process its own raw materials. The peculiarity of the soil and climate of the region requires correction of traditional cultivation technology. The purpose of the work was to test varieties and introduce peppermint, improve the traditional technology of its cultivation in the Far East. The results oflongterm field research conducted in 1992-2018 by the Primorsky research Institute and the Far Eastern Federal University prove not only the possibility, but also the prospects of growing mint. Longterm practical work has shown that the main feature of mint cultivation in the Far East is its annual culture. Leaving a raw mint plantation for use in the second and subsequent years is impractical for the following reasons. First, because of the weak overwintering (often to complete death) of plants that go into winter in a satisfactory and good condition. Secondly, because of the rapid compaction of the soil, which inhibits the development of plants. Loosening of the soil in the rows is complicated by the surface location of the rhizomes. Plants of the second year of life begin to grow in the spring earlier, but develop more slowly than newly planted ones. As a result, the yield of raw materials per unit area is 15-25% lower. Third, in the planting of mint, weeds quickly develop, which are difficult to fight with compacted soil. Every year, the clogging progresses, which is facilitated by slow growth and thinning of landings after overwintering. Fourth, the hardiness of varieties ceases to be a deterrent. This makes it possible to choose varieties of different terms of raw ripeness and the best quality indicators. The proposed technology allows you to get a yield of mint green mass of 14-18 t/ha in the first mowing and 8-11 t/ha in the second with high quality.
