摘要

FIELD: agriculture.;SUBSTANCE: method comprises selection of approbation bundle of plants and determining their strength features of the main stem. The approbation bundle is selected in phase of appearance of the reproductive organs of plants. As the strength features of the main stem the maximum di max and the minimum di min dimensions are measured in a horizontal plane of the second from below node of each i stem. According to data value λ, determined by the expression: <mrow><mi>λ</mi><mo>=</mo><mfrac><mrow><mstyle displaystyle="true"><munderover><mo>∑</mo><mrow><mi>i</mi><mo>=</mo><mn>1</mn></mrow><mi>n</mi></munderover><mrow><msub><mi>d</mi><mrow><mi>i</mi><mtext> </mtext><mi>min</mi></mrow></msub></mrow></mstyle></mrow><mrow><mstyle displaystyle="true"><munderover><mo>∑</mo><mrow><mi>i</mi><mo>=</mo><mn>1</mn></mrow><mi>n</mi></munderover><mrow><msub><mi>d</mi><mrow><mi>i</mi><mtext> </mtext><mi>max</mi></mrow></msub></mrow></mstyle></mrow></mfrac><mo>,</mo></mrow> where n is the number of stems in the approbation bundle, the following is predicted: if λ is at least 1.1 - there is no lodging, if λ=1.1÷1.7 there is weak lodging, if λ=1.7÷2.2 - average lodging, if λ=2.2÷3.0 - strong lodging, if λ is more than 3.0 - very strong lodging.;EFFECT: method enables to reduce labour intensity and to improve the accuracy of prediction of lodging of crops in the field conditions in the early stages of plant development.;3 tbl, 1 ex
