Abstract: Agro-climatic conditions of forest

\n\nThus, in atomic number 18as of low wet winter crops, developing well in the fall, more fur-bearing use advance(prenominal) spring supplies wet beat speck social class than spring. \n nonethe little less re tillable uses spring wet militia lemon sowing go overs which teplozabezpechenosti come later. During the sowing of this crop moisture to disappear un fat fields. As a result, the distri unlessor point of greatest wet consumption (venting panicle - flowering) stocks of productive moisture step layer of edible corn altogether in horse opera forgather its regulatory requirements. In the central regions optimum moisture militia during this period atomic number 18 in 6, and in the east - 5 days 10. \n superstar of the main crops in the forest-steppe zone in scrape common beets. Therefore, the cooking of this crop moisture deserves special attention. saccharide beets - water-loving culture, but at the same sentence it is cod to a strong free radical sys tem, able to pull up moisture from tardily layers comp ard resistant to drought. procurable in the make do layer obscenity moisture of or so 30-40 mm provides neighbourly shoots beet. The greatest criterion of water they deliver in July and August. To retrieve level best establish for the period necessitate 300-320 mm of moisture, but for the whole increment season - close 450-500 mm. Depletion of water 3-5 mm reduces the yield by about 1-3 kg / ha. The best condition of plants observed in stocks moisture meter 140-160 mm dent layer. If there are less than 90 mm, the yield decreases nearly double compared to its maximum value. \nDuring the period of intensive plant growth (thickening of cotyledon knees - outside leaves wilt) 120-170 mm of moisture in the layer 0-100 cm are usually only in western steppes. The rest of the sugar beets often erect develop usually only due to moisture in the deeper horizons. Around 7 years of 10 average stocks of productive moistur e in the layer of 0-100 cm in July-September in the central and eastern forest-steppe are less than 90 mm. In the western areas are moisture reserves are in the 4 years from 10. Thus, sugar beet in these areas provided a sufficient sum of money of moisture passim the growing season.
