摘要: 为解决西辽河平原盐碱地耕层较浅、犁底层上移、土壤盐碱化等问题,于2020—2021年在内蒙古自治区通辽市科尔沁左翼中旗花吐古拉镇开展田间试验。设置2种耕作方式(传统旋耕与粉垄耕作)、2个灌溉定额(2 100,2 700 m3/hm2)以及覆膜与浅埋措施,共6组试验处理,分别为2 100 m3/hm2灌溉定额+传统旋耕+浅埋(CK×NM)、2 100 m3/hm2灌溉定额+传统旋耕+覆膜(CK×DM)、2 100 m3/hm2灌溉定额+粉垄耕作+浅埋(FA×NM)、2 100 m3/hm2灌溉定额+粉垄耕作+覆膜(FA×DM)、2 700 m3/hm2灌溉定额+粉垄耕作+浅埋(FB×NM)、2 700 m3/hm2灌溉定额+粉垄耕作+覆膜(FB×DM)。分析不同灌溉定额下粉垄耕作与覆膜处理对0~40 cm土层土壤性质结构、盐碱含量和玉米产量的影响。结果表明,相较于CK×NM处理,在0~40 cm土层,粉垄耕作+覆膜处理的土壤容重降低8.4%~22.9%、土壤总孔隙度提高4.9~14.8百分点、土壤三相比R值降低34.6%~88.2%,其中,FB×DM处理的土壤容重、总孔隙度、三相比R值分别显著降低20.0%,-13.1百分点和88.2%;20~40 cm土层播种后土壤含水量提高5.5~12.1百分点,7.5~17.5 cm土层的土壤硬度提高33.4%~397.5%,其中,FB×DM处理的土壤含水量、硬度分别显著提高12.1百分点,214.3%;FB×DM处理CO2通量显著提高496.4%。相较于CK×NM处理,粉垄耕作+覆膜处理降低0~40 cm土层土壤pH值、总碱度、电导率和全盐量,降低幅度分别为0.7%~10.9%,2.5%~67.5%,24.3%~68.7%和10.3%~81.0%。其中,FB×DM处理的土壤pH值、总碱度、电导率和全盐量分别显著降低10.9%,48.2%,59.2%和80.0%。玉米出苗率、穗鲜质量和产量较CK×NM处理分别提高13.2~20.1百分点,52.5%~68.2%和22.4%~45.5%,其中,FB×DM处理的出苗率、穗鲜质量和产量分别显著提高20.1百分点,68.2%和45.5%。综合改良效果和玉米产量考虑,认为2 700 m3/hm2灌溉定额下粉垄耕作+覆膜处理(FB×DM)为西辽河平原盐碱地较为适宜的耕作模式。

Abstract:

To address issues such as shallow soil layers,upward movement of the plowpan,and soil salinization in the saline-alkali soils of the West Liaohe Plain,field trials were conducted in Huatugula Town,Horqin Zouyi Middle Banner,Tongliao City,Inner Mongolia Autonomous Region,from 2020 to 2021.Two tillage methods(traditional rotary tillage and powder ridge plowing),two irrigation quotas(2 100,2 700 m3/ha),and mulching and shallow burial measures were set up,resulting in six experimental treatments:2 100 m3/ha irrigation quota+traditional rotary tillage+shallow burial(CK×NM),2 100 m3/ha irrigation quota+traditional rotary tillage+mulching(CK×DM),2 100 m3/ha irrigation quota+powder ridge plowing+shallow burial(FA×NM),2 100 m3/ha irrigation quota+powder ridge plowing+mulching(FA×DM),2 700 m3/ha irrigation quota+powder ridge plowing+shallow burial(FB×NM),2 700 m3/ha irrigation quota+powder ridge plowing+mulching(FB×DM).The effects of powder ridge plowing and mulching treatments on soil properties,structure,saline and alkaline content,and maize yield in the 0—40 cm soil layer under different irrigation quotas were analyzed. The result showed that compared to the CK×NM treatment, in the 0—40 cm soil layer, the soil bulk density decreased by 8.4%—22.9%, the total soil porosity increased by 4.9—14.8 percentage points, and the soil three-phase ratio R value decreased by 34.6%—88.2% under powder ridge plowing + mulching treatment,among them, the bulk density, total porosity, and three-phase ratio R value of the soil treated with FB×DM treatment were significantly reduced by 20.0%,-13.1 percentage points, and 88.2%, respectively;soil moisture content after sowing increased by 5.5—12.1 percentage points in the 20—40 cm soil layer, soil hardness increased by 33.4%—397.5% in the 7.5—17.5 cm soil layer,among them, the soil moisture content, hardness of the FB×DM treatment increased significantly by 12.1 percentage points, 214.3%,respectively;CO2 flux of the FB×DM treatment increased significantly by 496.4%.Compared to the CK×NM treatment, the powder ridge plowing+mulching treatment reduced the soil pH value, total alkalinity, electrical conductivity, and total salt content in the 0—40 cm soil layer, with reduction rates of 0.7%—10.9%, 2.5%—67.5%, 24.3%—68.7%, and 10.3%—81.0%, respectively. Among them, the soil pH value, total alkalinity, electrical conductivity, and total salt content of the FB×DM-treated soil were significantly reduced by 10.9%, 48.2%, 59.2%, and 80.0%, respectively.Maize germination rate, ear fresh weight, and yield were increased by 13.2—20.1 percentage points,52.5%—68.2%, and 22.4%—45.5%, respectively,among them, the germination rate, ear fresh weight, and yield of the FB×DM treatment were significantly increased by 20.1 percentage points,68.2%, and 45.5%, respectively, compared to the CK×NM treatment. Considering the comprehensive improvement effects and maize yield, it is concluded that the 2 700 m3/ha irrigation quota+powder ridge plowing+mulching(FB×DM) is a more suitable cultivation mode for saline and alkaline land in the West Liaohe Plain.
