苏北沿海棉区是江苏省的主要产棉区,全区有棉田204.8万亩,占集体耕地面积42.96%,占江苏全省棉田23.02%,总产占全省26.46%。本区土壤属滨海盐渍土,含有不同程度的盐分,土壤瘠薄,结构差,遇雨容易板结,天旱又易跑墒,因此,棉花播种保苗困难,常导致棉产起伏不稳。为解决沿海棉区播种保墒技术,当地科研单位和群众通过多年来的试验与大面积生产实践,已摸索出一套一播全苗、早苗技术经验,现分述于下。
The northern Jiangsu coastal cotton area is the major cotton producing area in Jiangsu Province. There are 2,048,000 mu of cotton fields in the region, accounting for 42.96% of the total cultivated land area, accounting for 23.02% of the total cotton fields in Jiangsu Province, accounting for 26.46% of the total output. The soil in this area belongs to the coastal salty soil, which contains different levels of salinity, soils are infertile, the structure is poor, it is easy to compaction when it encounters the rain, and the drought is easy to run. Therefore, it is difficult for cotton to sow seedlings and often leads to unstable cotton production. In order to solve the sowing moisture conservation technology in the coastal cotton area, the local scientific research units and the masses have found out a set of technical experience of the whole plant and the early seedling through trial and large-scale production practice over the years.
