ain amount of time, production of fresh material and dry matter content and yield increase but not decrease. The same treatment, peanut production is also increased with increasing N fertilizer, while the highest are 60kg/hm2 in different nutrient management corn on peanut yield and quality have an impact on corn to the bottom of the leaf of treatment, the highest yield of peanuts, relatively good quality. Both corn and peanut prehensive economic benefits of intercropping maize and peanuts, is feasible, in the corn leaves to the bottom of the 225kg/hm2 N fertilizer in the case of corn and peanuts, the maximum economic benefits. Key words: corn, peanuts, symbiotic period, nutrient management 貴 貴州大學(xué)本科畢業(yè)論文(設(shè)計(jì)) 第 1 頁 1 前言玉米是我國主要的糧食作物,玉米是主要的糧食作物,也是優(yōu)良的飼料和工業(yè)原料(張起君等,1991。在相同的處理下,花生的產(chǎn)量也是隨著 N 肥的增加而增加,而均以 225kg/hm2為最高,在玉米的不同的營養(yǎng)管理對(duì)花生的產(chǎn)量和品質(zhì)也有影響,在對(duì)玉米去底部葉的處理下,花生的產(chǎn)量最高,品質(zhì)相對(duì)較好。綜合效益也是比較高的。對(duì)玉米筑黃糯 1 號(hào)與桂花 22 號(hào)兩個(gè)品種間作,不同的營養(yǎng)管理處理下的玉米和花生產(chǎn)量及營養(yǎng)品質(zhì)進(jìn)行系統(tǒng)研究,以期為探討出合理的玉米與花生共生期的營養(yǎng)管理技術(shù)研究提供依據(jù)。特此聲明。 本 科畢業(yè)論文論文題目: 玉米與花生共生期營養(yǎng)管理技術(shù)研究學(xué) 院:_農(nóng) 學(xué) 院__專 業(yè): 農(nóng) 學(xué) 班 級(jí):_06 級(jí) 學(xué) 號(hào): 060901110072學(xué)生姓名: 石 登 江 指導(dǎo)教師:_曹 國 璠__2022 年 5 月 貴 貴州大學(xué)本科畢業(yè)論文(設(shè)計(jì)) 貴州大學(xué)本科畢業(yè)論文(設(shè)計(jì))誠信責(zé)任書本人鄭重聲明:本人所呈交的畢業(yè)論文(設(shè)計(jì)) ,是在導(dǎo)師的指導(dǎo)下獨(dú)立進(jìn)行研究所完成的。畢業(yè)論文(設(shè)計(jì))中凡引用他人已經(jīng)發(fā)表或未發(fā)表的成果、數(shù)據(jù)、觀點(diǎn)等,均已明確注明出處。 論文(設(shè)計(jì))作者簽名: 年 月 日 貴 貴州大學(xué)本科畢業(yè)論文(設(shè)計(jì)) 第 I 頁 目錄摘要 ............................................................................................................................................II關(guān)鍵詞 : ................................................................................................................................IIABSTRACT.............................................................................................................................III1 前言 ..........................................................................................................................................1 研究或設(shè)計(jì)的目的和意義: ........................................................................................1 國內(nèi)外現(xiàn)狀和發(fā)展趨勢 .................................................................................................2 間套作對(duì)產(chǎn)量的影響 ..............................................................................................2 間套作對(duì)光能利用的影響 ......................................................................................3.3 間套作對(duì)養(yǎng)分利用的影響 ....................................................................................42 材料與方法 .............................................................................................................................4.1 供試材料 ....................................................................................................................4.2 試驗(yàn)地點(diǎn) ...................................................................................................................42.2 試驗(yàn)設(shè)計(jì) .......................................................................................................................5 主要栽培措施 ...........................................................................................................5 氮肥對(duì)玉米花生產(chǎn)量的影響 ..................................................................................6 樣本采集 ....................................................................................................................6 測定指標(biāo)及方法 .............................................................................................................7 測定指標(biāo) ..................................................................................................................7 測定方法 ..................
