  1. Using these data, we estimated cotton planting farmers " pesticides application equation and damage control production function, calculated the impact of bt cotton on pesticides use and cotton yield, and compared the poisonging probability due to pesticides application between bt cotton and non - bt cotton planting farmers. using bt cotton adoption area and the above results, this paper calculates the impacts of bt cotton on pesticides application, cotton production and poison cases all over china since the beginning of its adoption in china in 1997. the results demonstrate that the adoption of bt cotton reduced pesticides use approximatly 35kg per ha ; this is equivalent to 875 yuan of cost reduction

    利用這些數據我們估計了種植棉花（包括轉基因抗蟲棉和非抗蟲棉）農產農藥施用方程和棉花損失控制生產函數（ damagecontrolproductionfunction ） ，估計了抗蟲棉對棉花農藥使用和棉花產量的影響，同時比較了種植bt棉與非bt棉農產在使用農藥過程中中毒概率的差異，在此基礎上，利用抗蟲棉在全國各地的推廣面積以及以上的分析結果，測算了1997年以來抗蟲棉的推廣對全國棉花農藥使用量、棉花產量以及棉農施農藥中毒事件的影響，並對其經濟影響的不同受益者作了分析分解。
  2. As has been demonstrated by the data in tables 1, 3, 5 and 6, the total average yields of two rice crops have reached 15, 482 kg / ha ( 7, 937 kg / ha on early rice and 7, 545 kg / ha on late rice ) at shaoxing and 14, 876 kg / ha ( 5, 943 and 8, 942 kg / ha on early and late rice respectively at fuyang, the yields have touched or almost close to the yield target required for triple cropping of - " project of 15 ton grain yield per hectare " which is carrying out in the province

    表1 、 3 、 5 、 6中數據顯示，兩季水稻總平均產量在紹興已達到15 ， 482公斤/公頃（早稻7939 ，晚稻7545公斤/公頃） ，在富陽已達到14 ， 876公斤/公頃（早稻5943 ，晚稻8942公斤/公頃） ，該產量已達到或接近浙江省推行的噸糧田計劃中三季稻的產量目標。
  3. Data in table 5 show that although rice yield slightly increased with increasing plant density, the difference between densities was not significant, it indicated that in the case of high level fertilization, 300, 000 to 375, 000 hills per ha is enough for getting potential high yield

    表5中數據表明，雖然提高植株密度少量增加水稻產量，但密度間差異不顯著，這表明在高施肥量的情況下， 30萬和37 . 5萬蔸/公頃對獲得高產潛勢來說已很滿足。
  4. The experimental results showed that there was a significant difference between root yield and sugar yield under different planting patterns, the root yield and sugar yield were increased by 36. 7 % and 39. 8 % respectively, and the net profit was increased by 1602 yuan per ha for two lines within wide row with paper - pot in comparison with the treat of direct sowing in normal row

    摘要試驗結果表明，在同等條件下，由於栽培方式不同，密度不同，塊根產量、產糖量差異較大，以紙筒大壟雙行為最好，甜菜塊根產量、產糖量比對照小壟直播分別提高36 . 7 % 、 39 . 8 % ，每公項純增效益1602元。
  5. Adequate k - nutrition resulted in early maturity, maximum yields of nearly 25 mt ffb per ha in a fertilizer experiment and cumulative yield increases of more than 50 % after 6 years of planting in areas of commercial scale when compared with " normal " areas ( = inadequately supplied with k )

    肥料試驗結果顯示，足量鉀肥可促使早熟、最高產量每公頃鮮果串近25噸，在大面積種植條件下，六年累計比對照「常規」地塊（鉀不充足）增產超過50 % 。
  6. Research results from field experiments with yedan 14 ( table 2. ) suggested that density and ears play an decisive roles in yield formation, maize yield increased with density and ears but grains per ear and kernel weight reduced when density varied from 52500 to 75000 plants / ha

    掖單14大田試驗研究結果（表2 ）指出密度和穗數是產量構成的決定性因素，玉米產量隨密度和穗數增加而增加，但穗粒數和粒重當密度由52 ， 500增加到75 ， 000株/公頃時都降低。
