【摘要】：以新疆兵團(tuán)農(nóng)七師 12 5團(tuán)為例 ,探討建立了鄉(xiāng)鎮(zhèn)、團(tuán)場級(jí)土壤肥力信息管理和棉花施肥推薦支持決策系統(tǒng)。通過應(yīng)用地理信息系統(tǒng) (GIS)、數(shù)學(xué)模型等方法建立了土壤肥力評(píng)價(jià)模型和評(píng)價(jià)體系 ,結(jié)合肥料試驗(yàn)建立了棉花施肥推薦支持決策系統(tǒng)。系統(tǒng)具有生成鄉(xiāng)鎮(zhèn)、團(tuán)場地理信息土壤肥力分布圖、分析土壤肥力資源、提供棉花施肥咨詢與配方推薦等功能。系統(tǒng)應(yīng)用的結(jié)果表明 ,12 5團(tuán)土壤肥力大多處于中等水平 ,高、中、低肥力土壤的面積所占比例分別為 30 .5 %、4 1.5 %和 2 8.0 % ;2 0 0 0年推廣 2 .87萬ha,每公頃節(jié)約化肥投入成本 114元 ,增產(chǎn)皮棉 12 3kg ,合計(jì)節(jié)本、增效 15 84萬元
[Abstract]:Taking 125 regiment of Xinjiang bingtuan seventh division as an example, this paper discusses the establishment of information management system of soil fertility and recommendation and decision support system of cotton fertilization in villages and towns, and through the application of geographic information system (GIS). The evaluation model and evaluation system of soil fertility were established by mathematical model, and the decision system of recommendation and support for cotton fertilization was established in combination with fertilizer experiment. The system has the ability to generate the distribution map of soil fertility in villages and towns and farms with geographical information. The analysis of soil fertility resources and the function of cotton fertilization consultation and formula recommendation. The results of systematic application showed that the soil fertility of No. 125 regiment was mostly in medium level, high and medium. The proportion of low fertility soil area was 30. 5% and 28. 0%, respectively. In 00, 2. 870,000 ha was popularized, the cost of chemical fertilizer was saved by 114 yuan per hectare, and the production of lint was increased by 123kg. The total cost saving and efficiency increase were 15.84 million yuan
