摘要
1998年～ 2 0 0 0年对丘陵旱地冬小麦进行了覆盖施肥效应的研究 ,结果表明 :在试验条件下 ,施有机肥和覆膜或盖草较不施和裸地的处理耕层土壤含水量分别增加 0 .2 2 %～ 1.0 5 %和 1.2 9%～ 4 .11% ;以有机肥 16 5 0 0kg/ hm2和 3375 0 kg/ hm2、尿素 2 4 0 kg/ hm2和 36 0 kg/ hm2、磷酸二铵 371kg/ hm2和 5 5 5 kg/ hm2、硫酸钾 14 9kg/ hm2 和 2 2 2 kg/ hm2 、覆膜或盖草为最佳组合 ,其经济效益达极显著水平 ,而覆膜与盖草处理间差异不显著。为此认为 ,深耕结合施有机肥、适量化肥和盖草是丘陵旱地小麦保水增产的经济有效措施 。
Study on the mulching and fertilization of wheat at hilly areas was carried out Jiaodong area, Shandong province during 1998~2000. Results show that: As compared with CK, soil moisture content of the treatment was increased by 0.22%~1.05% and 1.29%~4.11%. The difference of dry matter and yeild between the combination (oganic fertilizer: 16 500 and 33 750 kg/hm\+2, urea: 240 kg/hm 2 and 360 kg/hm\+2, er'an: 371 kg/hm 2 and 555 kg/hm\+2, mulch) and other treatments was remarkable, but it wasn't remarkable be tween the treaments of film mulching and straw mulching. Considering the economic beni fit, we have come to the conclusoin that the technique including deep ploughing, oganic fertilizing, right chemical fertilizer application, straw mulching is a economic and effictive step for high yield and water saveing for wheat in hilly areas.
