地处江苏里下河腹部的宝应县,从80年代开始营造了万亩丰产林,并进行林农间种.据1987年5月对该县射阳湖琵琶圩速生丰产林小气候观测结果,证明池杉为里下河滩地开发的理想树种,林内小气候有利于间种小麦抗御高温逼熟,防止倒伏,提高产量,为江苏里下河滩地林农复合经营提供了科学依据. Baoying County, located in the belly of the Lixia River in Jiangsu Province, started to build 10,000 mu of high-yield forests in the 1980s and conducted inter-forest farming. According to the observation of the microclimate of the fast-growing and high-yield forests of Pipa Wei in Sheyang Lake in May 1987, Cedar is the ideal tree species for the development of the Lixiahe floodplain. The microclimate in the forest is conducive to the intercropping of wheat under high temperature to prevent lodging and increase the yield, which provides a scientific basis for the forestation and compound operation of the Lixiahe floodplain in Jiangsu Province.
