摘要: 由于积分回归法生物学意义明确,预报效果较好,已成为一种新的作物产量动态预报方法。为了完善黑龙江省主要作物的动态预报方法,提高作物单产的预报准确率,本文利用积分回归方法,随机选取以县为单元的研究对象,开展黑龙江省多种作物积分回归产量动态预报模型的适用性研究。结果表明:建立的黑龙江省6月下旬至9月下旬春玉米、大豆和水稻积分回归产量动态预报模型均通过了F的显著性检验,作物产量预报的平均差MD和相对误差RE均未通过显著性检验,表明建立的春玉米、大豆和水稻产量预报模型的预报效果较好;其中春玉米和水稻产量预报模型的预报准确率较高,模型预报的单产与实际单产的一致性较好。通过对2011-2014年黑龙江省作物单产进行试报和检验,发现春玉米、水稻和大豆单产的预报准确率平均为96%、95%和93%;表明积分回归方法对黑龙江省大豆单产预报的适宜性略差,积分回归法适用于黑龙江省水稻和春玉米单产的预报。基于积分回归法的原理,可以在黑龙江省开展春玉米和水稻单产的动态预报,并继续开展大豆产区积分回归产量动态预报的适用性研究。

Abstract: Integration Regression is a new method of yield dynamic forecast because it has a clear biological significance and good effects on prediction.Adaptability of dynamic forecast to main crops was studied with integration regression method in Heilongjiang province for improving the method of dynamic forecast and making forecast accuracy better.The results indicate that the built crop yield dynamic forecast models for corn,rice and soybean based on integration regression method during late June to late September pass the test of F significance.The smaller mean difference (MD) and relative error (RE) prove that all the models have better performances.More specifically,the spring maize and rice prediction models have excellent performances and are able to reproduce practical yields well.With model testing on the basis of field experimental data from 2011 to 2014,spring maize,rice and soybean yield prediction models achieve respectively the simulation accuracies of 96%,95% and 93%,which manifests that the adaptability of integration regression method is slightly worse for soybean and better for spring maize and rice in Heilongjiang province.In another word,based on integration regression method,dynamic forecast for corn and rice is feasible in Heilongjiang province,while its adaptability for soybean will need to be further studied.
