2013~2014年,以农华101为试验品种,设置55、65、75、40~90、35~165 cm等5个行距处理,研究不同行距配置对土壤含水量的影响。结果表明:不同行距配置土壤含水量随着土壤深度的增加,遵循先升高再降低的规律,土壤30~80 cm储存水分较多。降雨量较大的年份,行距配置对土壤含水量的影响不明显。在降雨量正常的年份,行距配置对55、65、75 cm均匀行处理影响不明显,行间距增加到一定程度后对土壤含水量的影响较为明显,行距35~165 cm配置的土壤含水量较低,较含水量最高处理低4个百分点。行距配置对40~90 cm处理的土壤含水量没有明显影响。
From 2013 to 2014, with five rows of 55, 65, 75, 40 ~ 90, 35 ~ 165 cm rows of pests treated with Nonghua 101, the effects of different row spacing on soil moisture were studied. The results showed that the soil water content with different row spacing increased with the depth of soil, and followed the law of first increasing and then decreasing. Soil moisture was stored at 30-80 cm. In the year with heavy rainfall, the effect of row spacing on soil water content is not obvious. In normal years of rainfall, the effect of row spacing on the uniform treatment of 55, 65 and 75 cm was not obvious. When the row spacing increased to a certain extent, the effect on soil moisture was obvious. The soil moisture content of 35 ~ 165 cm row spacing Low, the highest water content lower by 4 percentage points. Row spacing configuration had no obvious effect on the soil moisture content of 40 ~ 90 cm treatment.
