在黄泥巴新修梯田上运用掺施炉灰、绿肥压青和玉米秸秆还田三种方式进行综合改良试验研究，连续２ａ观察表明：①三种方式对黄泥巴土均有改良作用，其中以掺施炉灰的改土效果最为显著；②综合运用３项技术，１ｈｍ２掺施炉灰１５～３０万ｋｇ，绿肥压青６０００ｋｇ，玉米秸秆还田３７５０ｋｇ，能较快地改良黄泥巴的物理性状，提高土壤养分，达到一次性改良的目的。 In the newly constructed terraced paddy field, three methods were used to improve the soil, such as mixed ash, green manure and corn stalks. The results of continuous 2a observation showed that: ①the three ways all had the improving effect on the yellow mud soil, ②The comprehensive application of three technologies can improve the physical properties of Huangnimpa quickly by using 1 hm2 mixed with 1500 ~ 300000 kg ash, green manure pressing 6000kg and corn stalks returning to 3750kg , Improve soil nutrients, to achieve a one-time improvement.
