Изобретение относитс к лесному хоз йству , в.частности к способам получени се нцев в лесопитомниках.The invention relates to forestry, in particular to methods for producing seedlings in forest nurseries.
Известен способ посева сем н в лесопитомниках , при котором, с целью защиты се нцев от фузариоза, семена перед посевом протравливают, а в период после по влени всходов се нцы обрабатывают фунгицидами 1.The known method of sowing seeds in tree nurseries, in which, in order to protect the seedlings from fusarium, the seeds are pickled before sowing, and in the period after germination, the seedlings are treated with fungicides 1.
Способ имеет много недостатков, св занных с большими затратами труда, средств и с загр знением окружающей среды дохимикатами .The method has many drawbacks associated with high labor costs, funds and environmental contamination with dohimicates.
Наиболее близок к предлагаемому способ посева сем н хвойных пород в лесных питомниках, при котором семена высевают весной в отта вщую почву, когда она уже прогреетс солнцем 2.Closest to the proposed method of sowing seed of conifers in forest nurseries, in which the seeds are sown in spring in the desert soil when it is already heated by the sun 2.
При этом способе достигаетс известный эффект в получении свободных от фузариоза се нцев.With this method, a known effect is achieved in obtaining free from Fusarium seedlings.
Цель изобретени - более полное снижение поражаемости се нцев фузариозом.The purpose of the invention is a more complete reduction of susceptibility of fusariosis to seedlings.
Поставленна цель достигаетс тем, что почву с осени обильно увлажн ют а в начале та ни снега покрывают теплозащитным слоем на период до установлени температуры окружающей неукрытой почвы в пределах 25-ЗО С и высевают семена в теченнс одного-двух дней после сн ти теплоизол ционного сло . Сам теплоизол ционный слой выполн ют из полиэтиленовой пленки и опилок.The goal is achieved by the fact that the soil is abundantly moistened in autumn and at the beginning of the snow cover is covered with a heat-shielding layer for a period until the temperature of the surrounding uncovered soil is within 25 ° C and seed is sown within one or two days after removing the heat-insulating layer. . The heat insulating layer itself is made of polyethylene film and sawdust.
Дл проверки предлагаемого способа по сравнению с известным провод т опыты со следующими вариантами: 1 - посев сухими семенами (по известному сгюсобу), почваTo test the proposed method in comparison with the known method, experiments were carried out with the following options: 1 - sowing with dry seeds (by conventional method), soil
оттаивает весной; 2 - посев набухщими семенами в отта вщую весной почву; 3 - посев сухими семенами,почва замораживаетс в сухом состо нии; 4 - посев набухшими семенами, почву замораживают в сухом состо нии; 5 - посев сухими семенами, почву замораживают во влажном состо нии; 6 - посев набухшими семенами, почву замораживают во влажном состо нии. Результаты сохранности се нцев через 50 дней опыта показывают, что сохранность се нцев поthaws in the spring; 2 - sowing of swelling seeds in the soil defended by spring; 3 - sowing with dry seeds, the soil is frozen in a dry state; 4 - sowing with swollen seeds, the soil is frozen in a dry state; 5 - sowing with dry seeds, the soil is frozen in a wet state; 6 - sowing with swollen seeds, soil frozen in a wet state. The results of the safety of the sunbeds after 50 days of experience show that the safety of the sunbeds by
вариантам составл ет, %: 1 -1,1; 2-8,0; 3-8,8; 4-12,0; 5-22,4; 6-5,6.The variations are%: 1 -1.1; 2-8,0; 3-8.8; 4-12,0; 5-22.4; 6-5,6.
