(54) СПОСОБ ОПРЕДЕЛЕНИЯ ПЛОДОРОДИЯ ПОЧВЫ(54) METHOD FOR DETERMINING SOIL FERTILITY
Изобретение относитс к способам исследовани почв и может быть использовано в сельском хоз йстве.The invention relates to soil research methods and can be used in agriculture.
Известен способ определени плодороди почвы по гумусу, по которому определ ют емкрсть поглощени почвы и содержание в ней гумуса, а искомую величину выражают их соотношением. Способ позвол ет прогнозировать изменение плодороди почвы в процессе ее окультуривани по изменению реакционной активности гумуса There is a known method for determining soil fertility by humus, by which the absorption capacity of the soil and the content of humus in it are determined, and the desired value is expressed by their ratio. The method allows to predict the change in soil fertility in the process of its cultivation on the change in the reaction activity of humus
Недостатком известного способа вл етс необходимость выполнени тру- доемких химических анализов, которыеThe disadvantage of the known method is the need to perform laborious chemical analyzes that
не всегда точно определ ют биологическое качество гумуса, а следовательно , плодородие почва. The biological quality of humus and, consequently, fertility of the soil are not always accurately determined.
Известен также способ определени почвы путем проращивани сем н индикаторного растени на исследуемом образце почвы и на стандартном субстрате и сравнени проростков или растений, выросших на этих проростков на любой стадии вегетации 2.A method is also known for determining the soil by germinating seeds of an indicator plant on a soil sample and a standard substrate and comparing seedlings or plants grown on these seedlings at any stage of vegetation 2.
Известный способ достаточно продолжительный и не всегда дает точные результаты.The known method is quite long and does not always give accurate results.
Цель изобретени - сокращение сроков проведени исследовани и получение более точных результатов.The purpose of the invention is to reduce the duration of the study and obtain more accurate results.
Поставленна цель достигаетс тем, что из исследуемого образца почвы приготовл ют взвесь в воде, которой увлажн ют стандартный субстрат, и по интенсищности гуттации проростков,выросших на последнем и на стандартном The goal is achieved by the fact that from the studied soil sample a suspension is prepared in the water, which moistens the standard substrate, and by the intensity of guttation of seedlings grown on the latter and on the standard

Пример. Исследуемые образцы по 100 г воздушно-сухой почвы увлажн ют в конических колбах до оптималы.Example. The test samples of 100 g of air-dry soil are moistened in conical flasks until optimal.
ного состо ни и компостируют при 30 с, а если свежие образцы, то их не ком.- постируют. К образцам добавл ют 100 мп дистиллированной воды, взбалтывают и после оседани грубой суспензии в течение 10 мин взвесь вливают в другую посуду, отбирают 8 млт добавл ют в стандартный субстрат 50 г. В качестве , стандартного субстрата используют промытый и измельченный в шаровой they are composted at 30 seconds, and if they are fresh samples, they are not composted. 100 MPs of distilled water are added to the samples, agitated, and after coarse suspension has settled for 10 minutes, the suspension is poured into another container, 8 mlt are added to the standard substrate 50 g. As a standard substrate, washed and ground in a ball are used.
25 мельнице мореный песок. При определении плодороди образца почвы смоченный водой стандартный субстрат гуттацию проростков не вызвал, при добавлении в субстрат питательного25 mill of bog sand. In determining the fertility of the soil sample, the standard substrate moistened with water did not cause the guttation of seedlings, when nutrient
30 раствора наблюдаетс слаба гуттаци у 25% /проростков. Субстрат держат в стекл нных бшксах, закрытьах крышками -во-избежание испарени .При проращивании сем н скороспелого чмен на стандартном субстракте, обогащенной взвесью, полученной из исследуемого образца почвы, проростки из наклюнувшихс сем н по вились через двое суток при проращивании в термостате (). Гуттат собирают фильтровальной бумагой и взвешивают. Результаты приведены в табл. 1. Полученные данные позвол ют считать,что предложенный способ вполне приемлем дл использовани .30% of the solution observed weak gutta tion in 25% / seedlings. The substrate is kept in glass containers, covered with lids, to avoid evaporation. When seeds of early ripening are germinated on a standard substrate, enriched with a suspension obtained from the soil sample, seedlings from sticking seeds appeared two days later when grown in a thermostat () . Guttat is collected with filter paper and weighed. The results are shown in Table. 1. The data obtained suggests that the proposed method is quite acceptable for use.
