【摘要】：在進(jìn)行空心村整治復(fù)墾的同時,需添加適當(dāng)?shù)牟牧蟻硖岣咂淇筛?通過研究不同還田材料在冬小麥越冬前的土壤水分含量及剖面儲水狀況,來選擇保水性較好的材料進(jìn)行空心村整治還田。采用烘干法,分別在無還田材料,有機(jī)肥(雞糞)還田,粉煤灰還田,有機(jī)肥+粉煤灰還田四種處理下,在冬小麥的出苗期、三葉期和分蘗期測定土壤剖面105cm內(nèi)水分含量,每15cm測定一次,并計(jì)算各個生育期的土壤儲水量。結(jié)果表明:用不同材料進(jìn)行空心村整治還田的土壤水分含量不同,在冬小麥越冬前,用有機(jī)肥加粉煤灰還田后土壤0—105cm剖面各土層平均含水量為18.69%,比單獨(dú)用有機(jī)肥還田高出1.72%,比單獨(dú)用粉煤灰還田高出1.07%,比無還田材料高出2.84%。土壤剖面儲水量也以使用有機(jī)肥加粉煤灰還田后的為最大,為239.01mm,高于單獨(dú)用有機(jī)肥的18.17mm,高于單獨(dú)用粉煤灰還田處理的18.92mm,高于無還田材料的26.05mm。因此,在對空心村進(jìn)行整治復(fù)墾為耕地時,就水分利用及儲水保水性而言,用有機(jī)肥加粉煤灰進(jìn)行空心村整治還田處理時土壤水分狀況最佳。
[Abstract]:At the same time, proper materials should be added to improve the tillability of hollow village reclamation. The soil moisture content and profile water storage status of different returning materials before winter wheat winter were studied.To select better water retention materials for the hollow village renovation return field.Under the four treatments of no returning material, organic manure (chicken manure), fly ash and organic fertilizer fly ash, respectively, the moisture content of 105cm in soil profile was measured at seedling stage, three-leaf stage and tillering stage of winter wheat.Each 15cm was measured and soil water storage was calculated for each growth period.The results showed that the soil moisture content was different when the hollow village was renovated by different materials, and the soil moisture content was different before winter wheat overwintering.The average water content of soil 0-105cm profile was 18.69, 1.72 higher than that of organic fertilizer alone, 1.07% higher than that of fly ash alone, 2.84% higher than that of non-returning material.The maximum amount of soil water storage in soil profile was 239.01 mm after using organic fertilizer and fly ash, which was higher than 18.17 mm in organic fertilizer alone, 18.92 mm in fly ash alone, and 26.05 mm in non-returning material.Therefore, when the hollow village is reclaimed as cultivated land, the soil moisture condition is the best when the hollow village is treated with organic fertilizer and fly ash in terms of water use and water storage and water retention.
