Building on the corn and peanuts, 1 yellow waxy flowers on the 27th your intercropping two species, different nutrient management treatments of corn and peanut yield and nutritional quality of a systematic study to investigate a reasonable period of maize and peanut symbiosis provide a basis for nutrient management. Coexistence of nutrient management is the key to increasing yield and profit intercropping technology, corn intercropping peanut Although the effect may be dense, nutrient heterogeneity effect, being equivalent, the pensation effect between the plementary effects of other crops, but the coexistence of two kinds of crops Rapid growth at the same time petition is inevitable, therefore strengthening the coexistence of nutritional management technology is essential. Overall efficiency is relatively high. With the increase of fertilizer and the symbiosis of corn nutrient management, corn production is also significantly different, in the same processing, fertilizer to increase maize production has increased, and when more than a certain 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(yè) 1 前言玉米是我國(guó)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。佟屏亞,1993;鄺嬋娟等,1996), 進(jìn)入二十世紀(jì)八十年代以來(lái),隨著人們生活水平的提高,畜牧業(yè)的迅速發(fā)展,食物結(jié)構(gòu)發(fā)生了巨大變化,玉米在國(guó)民經(jīng)濟(jì)中的地位日益提高。人均占有玉米數(shù)量被視為一個(gè)國(guó)家或一個(gè)地區(qū)畜牧業(yè)發(fā)展和人民生活水平的重要標(biāo)志之一(佟屏亞,1994)。玉米由過(guò)去作為口糧向現(xiàn)在的飼料、工業(yè)原料方向轉(zhuǎn)變(佟屏亞,1995),玉米已發(fā)展成為世界重要的糧食、經(jīng)濟(jì)、飼料兼用的作物(佟屏亞,1994)。目前,全世界生產(chǎn)的玉米籽粒約有7080%作為飼料,約有1020%為人們食用,約有10~15%作為發(fā)展工業(yè)的原料(鄺嬋娟等,1996)。玉米可以與不同的作物進(jìn)行間套作,玉米在營(yíng)養(yǎng)期的管理也有著明顯的區(qū)別。玉米打頂對(duì)玉米果穗的發(fā)育有著重要的影響打頂,玉米打頂具有潛在價(jià)值,但打頂確實(shí)可以提高雙穗率,加大庫(kù)容,提高產(chǎn)量潛力 [27],玉米去底部葉,可以提高玉米的通風(fēng)效果?;ㄉc玉米在不同處理下的產(chǎn)量與品質(zhì)也有著明顯的不同。隨著N肥的增加,玉米與花生的產(chǎn)量都會(huì)隨著
