采用大田试验研究了聚垄、撩壕、盖草、覆膜４种耕种方式对湘南丘岗红壤旱地节水与培肥的影响．结果表明：聚垄、撩壕、盖草和覆膜处理均能提高土壤的含水量，其中节水效果以覆膜处理最佳，其余依次是盖草、撩壕和聚垄处理．同时，上述４种处理对培肥土壤也有一定的作用．与对照（平作）相比较，４种处理均能促进作物的生长发育，提高产量，增加产值，各处理净产值大小顺序依次为覆膜、盖草、撩壕、聚垄和平作 Field experiments were conducted to study the effects of four types of tillage methods, including ridge planting, trenching, covering grass and plastic filming, on water saving and fertilizing of red soils in hilly southern Hunan. The results showed that polygamy, trenches, cover grasses and film mulching treatments could increase the water content of the soil, and the water saving effect was the best by the film mulching. At the same time, the above four kinds of treatments also have some effects on soil fertility. Compared with the control, the four treatments could promote the growth and development of the crops, increase the yield and increase the output value. The order of the net output value of the treatments was covered with plastic film, covered with grass,
