三种向日葵单株产量估测方法的比较研究

MATHEMATICAL MODELS FOR PREDICTING GRAIN YIELD OF SUNFLOWER IN THE FIELD

摘要:

本文根据两年三个点次的田间试验结果研究了数位法、盘重法和盘径法对向日葵子实产量的预测效果。结果表明，三种方法建立的产量预测回归数学模型均有效、可靠。但在我国向日葵科研和生产实践中，以盘径法最为实用，建议推广应用。

Abstract:

Field experiments were made to study the usefulness of 3 techniques for predicting grain yield in sunflower. Results showed that all were effective, but the mathematical model involving measurements of head diameter proved the most valuable in view of practical application at the present stage of sunflower production.
