Be clearly and completely described the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
The embodiment of the present invention provides a kind of method of organic orchard mixing intercropping plant, and be applicable to the orchard of planting Organic Apple, the method comprises:
Needing to increase in organic orchard of soil nutrient, with French marigold, savoury and Ageratum conyzoides three kinds of fragrant plants for plantation;
March, the fruit tree in organic orchard sowed the seed of three kinds of fragrant plants in the ranks, with interlacing planting patterns mixing intercropping plant three kinds of fragrant plants, covered White plastic film after plantation;
When three kinds of fragrant plant heights of seedling are 8cm ~ 12cm, carry out a transplantation of seedlings, retain seeding row spacing 0.2 × 0.4m;
Water every 10 days at the early growth period of three kinds of fragrant plants, and intertill and clean tillage keeps mixing intercropping plant district without weeds, the middle and later periods self-sow of three kinds of fragrant plants, cradled in late July and October, cradled the fruit tree natural decomposition in the ranks that thing stays organic orchard after cradling.
In said method, organic orchard is: be in moistening continent, temperate zone half monsoon sex climate, organic orchard that average annual rainfall is 500mm ~ 700mm, what plant in organic orchard is that life in 15 years, Growth status are good, the uniform fruit tree of tree vigo(u)r, and fruit tree seeding row spacing is 5 × 6m.
By mixing intercropping plant three kinds of fragrant plant French marigolds, savoury and Ageratum conyzoides in orchard moderate proportions, compared with the natural grass of orchard, although reduce Soil Microorganism amount, but have also been changed structure of soil microbial community, improve soil enzyme activities (especially urase and catalase), soil moisture content, improve soil pH value, and add soil nutrient content, apple orchard soil is improved there is significant effect.The inventive method can change that the most apple orchard soil of China is more barren, and the content of organic matter is low, and most dependence uses chemical fertilizer to ensure the demand of fruit tree to nutrition, seriously governs the problem of producing that organises of China's apple.
Below in conjunction with specific embodiment, method of the present invention is described further.
With organic sightseeing apple orchard, king home, stream villages and small towns, Changping District, Beijing for pilot, with the fragrant plant that French marigold (TagetespatulaL.), savoury (Saturejahortensis), Ageratum conyzoides (Ageratumhoustonianum) are plantation, with French marigold × savoury × Ageratum conyzoides mixing intercropping plant, with natural grass district for contrast, the inventive method is specific as follows:
