Abstract

Способ прогнозирования полегания растений сельскохозяйственных культур, включающий отбор апробационного снопа растений и определение у них признаков прочности главного стебля, отличающийся тем, что апробационный сноп отбирают в фазу появления репродуктивных органов у растений, а в качестве признаков прочности главного стебля измеряют максимальный dи минимальный dразмеры второго снизу узла каждого i стебля в горизонтальной плоскости и по значению величины λ, определяемой выражением:, где n - число стеблей в апробационном снопе, прогнозируют: при λ менее 1,1 - полегания нет, при λ=1,1÷1,7 - слабое полегание, при λ=1,7÷2,2 - среднее полегание, при λ=2,2÷3,0 - сильное полегание, при λ более 3,0 - очень сильное полегание.A method for predicting the lodging of plants of agricultural crops, including selecting an approbation sheaf of plants and determining their signs of strength of the main stem, characterized in that the approbation sheaf is selected in the phase of the appearance of reproductive organs in plants, and the maximum d and minimum d sizes of the second bottom are measured as signs of the strength of the main stem node of each i stem in the horizontal plane and by the value of λ determined by the expression:, where n is the number of stems in the approbation sheaf, forecast They do it: for λ less than 1.1, there is no lodging, for λ = 1.1 ÷ 1.7 - weak lodging, for λ = 1.7 ÷ 2.2 - average lodging, for λ = 2.2 ÷ 3.0 - strong lodging, with λ more than 3.0 - very strong lodging.
