Effect Of Planting Orchard Grass On Fei Peach Growth Environment

Fei Peach cultivation has a long history,and the local people only know that this species is a seed, and do not know its origin, Fei Peach is also called "Buddha peach", and its cultivation has a long history, It has been 1200 years of history, As a major feature of peach varieties, it gets well received, But in the development of fat peach, due to improper management measures, excessive development of light weight management and heavy crop light quality, heavy on the light on the ground and excessive application of chemical fertilizers and pesticides, improper use of water and Fertilizer on land, farming system loopholes, products beat as early as listed, peach fat and delicious, flavor and storability and quality in a gradual decline, seriously affecting the Fei peach quality, Most of the local orchard farming tillage system, the bare surface soil, water and fertilizer retention ability, To improve and enhance the fertilize r peach quality and efficiency, And this study selected in the bare drain the orchard surface natural grass, the investigation of natural grass of fat peach growth environment influence and good reputation and benefit, Most of the local orchard farming tillage system, bare surface, soil water and fertilizer retention ability, In the selection of bare orchard surface natural grass in this study, the influence of the investigation of natural grass on Peach Growth environment to improve the quality and efficiency of peach orchard, The main results are as follows:(1) In general, the orchard natural grass population clusters growth, Natural grass should retain fruit row one or two year’s old weeds, natural weeds, perennial grass weeds, And remove weeds, Green bristlegrass(Setaria viridis(L,) Beauv,)and Crabgrass(Digitaria sanguinalis(L,) Scop,)has plant height, density, and they can effectively prevent the surface from direct sunlight, perennial weeds medium height, density, and they also can effectively block the direct sunlight to the table, The biomass is relatively large, in nature the grass in the garden accounted for a larger proportion, can be considered as fertilizer orchard natural grass dominant varieties, change below peach growing environment by the growth of grass species will be further elaborated, Natural grasses, such as Humulus, Imperata, amaranth and so on, because of its high growth, growth pattern and the field management, which belongs to the weeds in orchard, should be cleared in the natural grass in Tao yuan fertilizer,(2) The influence of content of natural grass on soil organic matter decreased with the increase of soil depth, This is because the orchard grass is shallow in grass root, Root depth is 0-40 cm, and in the daily management of the orchard, tillage depth is generally not too large, Plant debris was plowed and generally stay in the shallow soil, According to experimental measurements, peach roots generally exist in the soil layer of 0-40 cm therefore, From the point of view, the increase of organic matter content, natural grass relative to clean tillage, It has obvious advantages,(3) Potassium distribution in various soil layers is random, and the difference is not obvious, In addition, natural grass orchard and soil tillage orchard on nitrogen and phosphorus content in orchard soil decreased with increasing soil depth, The nitrogen and phosphorus content of orchard grass in every layer was significantly lower than that of clean tillage orchard, In general, grass orchard early on the grass to the lack of management, and pay little attention to the nutrition supply of seed, And this makes the competition between grass and fruit nutrie nt, And this leads to reduced nitrogen phosphorus and potassium content in orchard soil, In the production process should pay attention to strengthening the management of grass, applying the appropriate fertilizer on the grass in order to ensure the balance in the early grass orchard soil elements,...
