有的社队在平整棉田时未保留表土,特别是用铲土机平整的田块,把高处熟土推到低处,耕层变为生土。这些生土地,质地不好,干(干燥缺水),硬(土质紧实),瘦(有机质极少,营养甚缺),凉(透气性差,吸热保温不好,地凉)。如不采取措施,将会影响棉花出苗,即使出了苗也长不起来,花铃少,产量低,品质差。 Some communes and brigades did not keep the topsoil during the smoothing of the cotton fields. In particular, they used flattened fields of shovels to push the tops of ripened soils to a low level and turn the topsoils into raw soil. These raw land, poor quality, dry (dry and water), hard (soil compaction), thin (very few organic matter, lack of nutrition), cool (poor ventilation, endothermic insulation is not good, to cool). If you do not take measures that will affect the emergence of cotton, even out of the seedlings also grow up, less flowers, low yield, poor quality.
