蓄水覆盖丰产沟,适宜在土层深厚的山区丘陵旱坡地上推广。经过3年试验证明,实施蓄水覆盖丰产沟比同类对照田产量提高1倍以上。具有抗旱蓄水、增温保墒、加深耕层、集中施肥,防止水土流失等综合功能。一、起垄筑沟,操作规程修筑丰产沟应沿等高线由内向外,由低向高,依次完成。要求每3年轮翻一次。 1.垄沟规格每1.2米为一单元,垄宽0.6米,高0.3米;沟宽0.6米;活土层0.5米。 2.操作程序先将第一单元表层熟土向空地翻起,生土外露后,把靠里一半的生土挖起,向外筑垄,然后把活土回填到沟内。这样轮回循环,逐次完成。最后在地面上形成垄沟相间的丰产沟。要求达到垄硬、沟
Impoundment Feng Shou ditch, suitable for deep in the soil hills and hills on the slopes to promote. After 3 years of testing proved that the implementation of impoundment Feng Shougou than similar control field output increased more than 1 times. A drought-resistant water storage, warming soil moisture, deepening the tillage, concentrated fertilization, prevent soil erosion and other comprehensive functions. First, the ridge ditch, operating procedures to build Feng ditch should be along the contour from the inside out, from low to high, followed by completion. Requires round every 3 years. 1. Ditch specifications every 1.2 meters for a unit, the ridge width of 0.6 meters, 0.3 meters high; width of 0.6 meters; living soil 0.5 meters. 2. Operating Procedures First, the first unit of the surface of mature soil turn to the open space, raw soil exposed, half of the raw soil dug up, outward ridge, and then backfill the living soil into the trench. This cycle of recycling, one by one to complete. Finally, the formation of furrows and ditches on the ground. Required to reach ridge, ditch
