The invention relates to a corn
intercropping grass belt planting method capable of reducing sloping field water and
soil loss greatly. The method includes the following steps that corns are planted by adopting
seedling transplantation, wide and narrow row spacing and
plastic film mulching, row spacing is 45 cm, large line spacing is 120 cm, small line spacing is 35 cm, after ditching is conducted,
farmyard manure and chemical
fertilizer are applied into the ditches together, two seedlings are transplanted in each pond, and after soil covers the seedlings, the film is paved.
Intercropping grass is African green bristlegrass and white clover which are sown in a
mixed mode, wherein the green bristlegrass is 40g / m<2>, the white clover is 15g / m<2>, and the belt width is 40 cm. The
farmyard manure is applied to corn wide planting belts and is covered by the soil, then 1cm-thick fine sand is paved, compound
fertilizer and grass seeds are scattered on the fine sand, then about 1cm-thick sand covers the compound
fertilizer and the grass seeds, the grass seeds, the compound fertilizer and the sand are mixed by hands, and finally the grass seeds, the compound fertilizer and the sand are compacted by using a hoe and covered by a ventilation and water permeable covering object. By means of the method, sloping
field corn yield can be guaranteed, a good water and
soil conservation effect can be achieved, and the method is a reasonable and feasible mountain farming
sustainable development cultivation measure.
