Zasushivanie plants

Five hours later drying paper replace na fresh ( if plants are placed in the evening, then shift to do early in the morning). After two or three such turns of the paper are changed twice a day (morning and evening), and four-cut for two days - just once a day. I'm just drying the paper sheet plant do not change. excavated drying the paper is dried in the sun or on the stove. Drying lasts three to seven days, depending on the weather and the plants themselves. Changing the paper drying, inspect the plant, selected already dried up. Plants should not be any overdry (become very brittle, crumble) or nedosushivat (Port - blackened, moldy). Signs of dried plants to the best: the commitment and lifted up one end, it does not bend applied to the lips, it seems warm. It is easier for plants to dry in the drying press, in the so-called grids. This two frames with wire mesh. Filled grid pulls the rope tight. Very good drying quilted mattress. hygroscopic cotton fiber deployed in the 0.5 cm and cut to size herbarium specimen. The cut pieces glued or sewn up in tissue paper. sheets with plants laid out between the mattress as well as between batches of drying of paper (one mattress replaces the stack of paper). A change of mattresses do not need: the plant lies between them, until dry. This method is particularly useful for drying delicate plants. Drying nets are better than between the planks. Nets easily move from place na place they can hang in the sun, put on the stove; plants in them dry faster, better preserve color. The dried plants mounted on a half sheet of paper: each sheet is only one kind of plant. to the paper plant is attached with paper strips, blurry at the ends with glue. Each sheet is provided with a label containing the name of the plant and all records of it (location, time, etc.). Sheet with attached plant is put into the cover - inside a double sheet of paper (no dryer). sheets with the same kind of plants are placed in a common cover. For more information about methods of collecting and zasushivaniya different plants are presented in the manuals Leontief and Syuzeva. Collected plants can be grouped according to habitats: prairie, field, steam, sand, swamp, spruce forest and etc. Thus, you gradually learn the plants of different habitats and notice that each one has its own composition "of the population." To compare the local phenological observations with those who managed to do for suburban areas, we provide data from periods of periodic table phenomena, compiled IA Zdanovsky. These tables Zdanovsky date farming and the phenomena of our time are of particular interest. fundamental restructuring of agricultural life on the basis of collectivization, the introduction of rational methods of agriculture, the introduction of machines, the widespread use of the latest achievements of science and technology in the field agricultural labor - have radically changed and the ways and the pace and timing of agricultural activities. Change sowing by harvesting machinery, which were carried out much faster. Comparing the old and new dates for agricultural work, it is easy to discover the profound changes that have occurred in agriculture with a victory socialism in our country.
