Studies on Spacial Distribution Pattern and Sampling Techniques of Henbits in Winter Wheat Field
Han Wei et al (Mengcheng County Station of Plant Protection, Mengcheng 233500)
The study showed that the distribution pattern of henbits in winter wheat field was contagious in the different den sities.The contagious intensity was enhanced with the increase of the density of the weed.The basic element of the distribution was colony and the individual plant drew each other.And at the average density 4.182 2,the main reason for the contagious distribution pattern was due to the aggregated falling of the weed seeds; at the arerage density 4.182 2,the main reason was due to the mixture of wheat seeds and weed seeds and fertilizing poor fermentation compost.The types of parallel and chessboard sampling were suitable for the field investigation of the weed.The theoretical sampling number at different weed density was put forward.
