Abstract
1. Способ определения оптимальной дозы первой азотной подкормки озимых колосовых культур, включающий в себя определение времени начала весенней вегетации (ВНВВ) озимых колосовых культур, отбор почвенных образцов из слоя 0-20 см и растительных образцов с учетных площадок поля в период начала весенней вегетации растений, подсчет в них всех живых стеблей длиной >10 мм, определение густоты агрофитоценоза (АФЦ), принятие решения о величине планируемой урожайности, отличающийся тем, что дополнительно осуществляют отбор почвенных образцов из слоя 20-40 см, в которых определяют уровень фосфорного и калийного режимов АФЦ по содержанию в почве подвижного фосфора (PO) и обменного калия (KO), в почвенных образцах из слоя 0-20 см определяют уровень азотного режима АФЦ по содержанию азота обменного аммония (N-NH), а определение оптимальной дозы первой азотной подкормки озимых колосовых культур рассчитывают по формулегде d= x-K(разность между величиной каждого фактора и величиной его константы),x - фактор,K - константа фактора (среднемноголетний уровень фактора),Y - оптимальная доза первой азотной подкормки, кг азота в д.в./га,x- содержание азота обменного аммония (N-NH) в почве, мг/кг,x- содержание подвижного фосфора (PO) в почве, мг/кг,x- содержание обменного калия (KO) в почве, мг/кг,x- густота АФЦ, шт. стеблей/м,x- планируемая урожайность, ц/га.2. Способ по п. 1, отличающийся тем, что, при «позднем» ВНВВ расчетную дозу азотной подкормки (Y) увеличивают в 1,25 раза.3. Способ по п. 1, отличающийся тем, что при низких запасах продуктивной влаги в почве к моменту начала весенней вегетации растений в слое 0-100 - 100-140 мм расчетную дозу азотной подкормки (Y) уменьшают в 1,33 раза.4. Способ по п. 1, отличающийся тем, что при очень низких запасах продуктивной1. A method for determining the optimal dose of the first nitrogen top dressing of winter cereal crops, including determining the time of the beginning of spring vegetation (VNVV) of winter cereal crops, selection of soil samples from a 0-20 cm layer and plant samples from the registration sites of the field during the beginning of spring plant vegetation , counting all living stems in them> 10 mm long, determining the density of agrophytocenosis (AFC), deciding on the size of the planned yield, characterized in that they additionally take soil samples from the layer 20-40 cm, in which the level of phosphorus and potassium regimes of the AFC is determined by the content of mobile phosphorus (PO) and exchange potassium (KO) in the soil, the level of the nitrogen regime of the AFC is determined in soil samples from a 0-20 cm layer by the nitrogen content of exchange ammonium ( N-NH), and the determination of the optimal dose of the first nitrogen feeding of winter cereal crops is calculated using the formula d = xK (the difference between the magnitude of each factor and its constant value), x is the factor, K is the factor constant (long-term average factor level), Y is the optimal dose of the first nitrogen subcortex microliters, kg of nitrogen in AI / ha, x- content of nitrogen of exchange ammonium (N-NH) in the soil, mg / kg, x- content of mobile phosphorus (PO) in the soil, mg / kg, x- content of exchange potassium (KO) in soil, mg / kg, x- density of APC, pcs. stems / m, x - planned yield, t / ha. 2. The method according to claim 1, characterized in that, with a "late" VNVV, the estimated dose of nitrogen top dressing (Y) is increased 1.25 times. The method according to claim 1, characterized in that at low reserves of productive moisture in the soil, by the time the spring vegetation of the plants begins in the 0-100-100-140 mm layer, the calculated dose of nitrogen fertilizing (Y) is reduced by 1.33 times. The method according to claim 1, characterized in that at very low productive reserves
