The invention provides a farmland comprehensive planting method based on
crop diversity and an ecological
buffer zone, which comprises the following steps: firstly, constructing a
crop strip
relay intercropping and multi-variety mixed
sowing system, carrying out
intercropping or
relay intercropping and inter-variety mixed
sowing on different crops in a farmland, and then, constructing a layered
vegetation and
filter material coupled farmland ecological
buffer zone, according to the method, ecological buffer zones of arbor,
shrub and herbaceous composite
vegetation are constructed on the boundary of a farmland or the two sides of a
ditch, then ecological prevention and control measures of double-lamp double-wave-band trap lamps and natural enemy release are deployed, and by combining sex
pheromone trapping, measures of release of natural enemy including
trichogramma, biological preparation and botanical
pesticide spraying and frequency vibration type insecticidal lamps, the natural enemy release and the natural enemy release are combined, so that the ecological buffer zones of the arbor, the
shrub and the herbaceous composite
vegetation are obtained. Finally,
filter material recycling and farmland soil improvement measures are carried out,
organic fertilizer and microbial agents are combined to be applied to soil, the use of chemical herbicides is reduced in a mechanical weeding mode, and in a word, the method has the advantages of being
environmentally friendly, increasing and stabilizing the yield and not damaging the
ecological environment.
