为了改善新罗区黄泥田土壤质量、提高土壤肥力,对新罗区15个乡镇213个黄泥田耕层土样进行了检测分析。结果表明:该地区黄泥田土壤酸化明显,有机质、碱解氮含量丰富,有效磷、速效钾比较缺乏,不同乡镇之间土壤养分含量不平衡,有机质、碱解氮含量变化小,磷与钾的含量差异大。要将中低产的黄泥田培育成中高产的浅灰黄泥田或乌黄泥田,可从增施有机肥,平衡土壤养分;推广稻草还田,扩种冬季绿肥;结合深耕施用石灰,逐步加厚耕作层;开展测土配方施肥,控氮肥增施磷钾肥等方面进行改良。
In order to improve soil quality and increase soil fertility in the yellow muddy soil of Xinluo District, soil samples from 213 paddy soils in 15 townships of Xinluo District were detected and analyzed. The results showed that the soils in the yellow muddy soil of the area were obviously acidified, rich in organic matter and alkali-hydrolyzable nitrogen, lack of available phosphorus and available potassium, soil nutrient content imbalance among different towns and townships, little change of organic matter and alkali-hydrolyzable nitrogen content, Large differences in content. In order to cultivate middle-low yield of yellow muddy soil into middle-high yield of light-gray yellow muddy soil or black-yellow muddy soil, organic fertilizer can be added to balance the soil nutrient; to promote the straw returning to the field and expand winter green manure; Tillage layer; to carry out soil testing and fertilizer, nitrogen and phosphorus fertilizer and other aspects of improved control.
