试验研究杨粮间作系统中根障对土壤水分的影响结果表明,在集约经营条件下设置根障可有效改善间作农田的土壤水分含量,提高幅度为15.8％～17.7％;测定表明,灌溉15d后根障使间作系统农田土壤水分消耗的速度平均每天减缓0.5％。
The results showed that under the condition of intensive management, the root barrier could effectively improve the soil moisture content of intercropping farmland with the increase range of 15.8% -17.7%. The results showed that after 15 days of irrigation, Barriers slowed the average daily water consumption by 0.5%.
