泰县通扬运河以南砂土地区共有四十多万亩耕地,自1965年大面积旱改水以后,接着又发展了麦稻稻三熟制.但由于这个地区土质砂,田底薄,加之稻草不还田,有机肥料跟不上,因而出现了“高复种,低产量,高成本,低收入”的情况.麦稻二熟,养地用地仍然不能很好结合.而麦豆二熟,由于大豆产量较低,全年产量又不能确保.实践证明,针对本地区田少人多(每人平均只有七分地左右)的特点,提高复种指数仍然是发展农业生产的重要途径,问题是要发展既提高复种指数,又培肥地力,既增加产量,又降低农本的三熟制.
There are more than 400,000 mu of arable land in the sand soil area south of the Tongyang Canal in Taihe County. After a large area of dry land was changed to water in 1965, the third rice crop was developed, but because of the sandy soil in the area and the thin field at the bottom, Straw does not return to the field, organic fertilizer can not keep up, resulting in a “high-resuming, low-yield, high-cost, low-income” situation.Myrodry second crop, land for cultivation is still not well combined.White bean, Due to the low yield of soybean, the annual output can not be ensured.It has been proved that to increase the multiple cropping index is still an important way to develop agricultural production in light of the characteristics of many locals and fewer people in the region (each with an average of only about seven) It is necessary to develop not only to increase the multiple cropping index but also to cultivate fertility, which not only increases the output but also reduces the three-cropping system of farming.
