Abstract:
مشروع مزرعة قصب السكر في محافظة ميسان من المشاريع الاستراتيجية التي انشئت في سبعينات القرن الماضي, بعد نجاح زراعة قصب السكر واستنباط اصناف ملائمة للزراعة في المناطق شبه المدارية بين خطي عرض 300 جنوبا الى 340 شمالا عن خط الاستواء. تقع مزرعة قصب السكر (منط | Sugar cane plantation in the province of Maysan, a project of strategic projects established in the seventies of the last century, after the success of the cultivation of sugar cane and devise appropriate varieties for cultivation in subtropical areas between latitudes 300 south to 340 north from the equator. Sugar cane plantation is located (the study area) between latitudes 310.40 - 300.30 to the north, and the brackets of the length 470.10 - 470.06 east, mediates Hungary Great River (a tributary of the Tigris River) farm, which is the source of President perfusion of the farm. Soil sedimentary farm sugar cane, as a result of DepositionsTigris River and its branches, so they made up mainly of alluvial mud and silt, sand and clay. And have a minor decline of no more than 0.002 from the northeast to the west where the altitude ranges ground (7 - 2 M) above sea level.The climatic factors of solar radiation and temperatures suitable generally for the cultivation of sugar cane crop, especially after the adoption of the autumn farming system (start cultivating the mind in mid - August until mid - October month - a period Germination - with and there is a dormant period after the tailoring stage for a period of four months to inadequate climatic conditions extends until June to begin later growth stage Great - Vegetative growth - ). The rainfall system is not suitable for the cultivation of sugar cane, but on the contrary have to rain a negative effect, through the water increase in plant sugar cane for the required limit, as well as the rainfall in the winter has a negative effect, as the process of harvest delay and increased impurities ratio sugar juice and sugar extracted later.The jungles of the problems of the sugar cane crop, and is the deterioration of the quality and the winning amount for the sugar cane crop, as well as being host to many insects and plant pathogens and cause extra costs of labor, machinery, equipment and pesticides. And it is the growth of the bushes thickly in the early growth, which allows them to excel in growth on the main crop (sugar cane).Texture of soil to farm sugarcane as samples are Specimens alluvial mud, mud - placer as well as having Specimens sand at the rear of the second series of Saada. Accordingly, the physical properties of soils farm sugar cane does not represent any hindrance or a determining factor for the production of sugar cane crop with a good management of the soil and to suit the crop. It represents a cation exchange capacity (sodium absorption ratio) the soil's ability to deliver food material to the plant. And the ability of the soil depends on the ratio of colloids (size beloved diameter less than 2 microns) In other words, based on the proportion of Mvsolat mud and silt in the soil, because they are just that diameters of grains crystallized (2microns or less). And the value is 24 mg /100g minimum capacity of cationic exchange. Analyses of samples taken for chains of sugar cane plantation soils have shown that the value of cation exchange capacity 43 mg /100g, as a result of the high percentage of clay, and it does not represent the cation exchange capacity is no obstacle in the cultivation of sugar cane crop. Soil farm sugarcane neutral in terms of the degree of interaction, but it is to be poor in terms of food material in the soil, especially the elements phosphorus and nitrogen and potassium, so these elements being added through manure during certain periods and quantities needed by the plant.Degree drainage soils for sugarcane project varied between good, medium and bad, which is taken into account in the perfusion operations or when a land reclamation operations and reduce the salinity in the soil. The percentage of salinity and salinity in soils and accumulation of specific sugar cane crop factors. Salts has spread to large areas of farm soils sugar cane as a result of neglect and even in those lands that are Terpha with good drainage.This call to the speed of Reclamation irrigation canals and drainage and disposal of underground water near the surface of the earth, and that contributed to the increase of salinity in the soil. And creating irrigation systems and effective puncture in order to make the sugar cane project leader in Iraq with economic returns, which contributes to assign the economy of Iraq project, especially since the project is linked with other projects such as sugar cane factory - farm or constructed to take advantage of the remains of sugar cane after its age and extract sugar, such as near a farm sugar cane paper factory.The revival of the sugar cane project will encourage the relevant government departments, work to find similar projects both in Maysan or in other provinces and then there will be a new look at Iraq's economy is based on the establishment of commercial and strategic agricultural projects that will create industries are its Article preliminary cultivated crops or residues. Or projects that are based on the cultivation of cash crops, according to modern methods of agriculture. And then create a multi - polar economy countries and reduce dependence on oil and its derivatives as an economy of the country unilaterally.
