木薯套种西瓜甜瓜栽培模式研究

为了充分利用土地资源,提高土地利用率、单位面积产量和效益,进行了旱坡地木薯套种西瓜、甜瓜栽培模式研究。试验以单种木薯为对照,应用木薯与西瓜、木薯与甜瓜2种套种模式,每种模式设计了木薯与西瓜或甜瓜同期种植、西瓜或甜瓜定植20d后种植木薯、西瓜或甜瓜定植40d后种植木薯3个处理。结果表明,木薯套种西瓜、甜瓜,667m2最高收益分别为1801.71和1954.52元,比对照分别增收1352.88、1504.69元,增产增效显著。不同处理以西、甜瓜定植20d后种植木薯效果最好,可有效解决2种作物间争光抢肥的矛盾,获取最佳经济效益。

Intercropping of Cassava and Watermelon or Melon

Intercropping of cassava with watermelon or melon were tested in hilling dry land to increase the land usage and productivity per land unit.Two intercropping model,watermelon+cassava and melon+cassava,were tested with the treatments of both crops were sown at the same time,cassava were sown 20 days and 40 days later than watermelon or melon.The intercropping system produced 1 801.71 and 1 954.52 yuan more return per 667 m2 than single cropping of cassava.The best treatment was that cassava was sown 20 days later than watermelon or melon.
