In this article, combined the unearthed documents in dunhuang and the surrounding area and some traditional historical records, the author would analyze the cultivation and utilization on the ma - crops of dunhuang from tang dynasty to early song dynasty, which is mainly composed of four sections, the generalisation of the cultivation and utilization on the ma - crops in ancient dunhuang, the category, area and per mu yield （ 畝產 量 ） in given period, the utilization on the fibre and products and the ma - seed （ 麻 籽 ） and the ma - oil （ 麻油 ）, and the price ratios between the ma - crops and the copper cash （ 銅錢 ） and wheat
因此，麻在古代敦煌社會經濟生活中的重要地位和作用未得到客觀、公允的評價和認知。本文欲
結合敦煌及周邊地區的出土文獻和傳統的史籍資料，分析探討唐五代宋初敦煌麻的種植及利用狀況，主要涉及到四個方面：古代敦煌地區麻的生產利用總述，唐五代宋初敦煌麻的種植品種、面積和畝產量，麻纖維及其產品麻
籽、麻油的利用和它們與銅錢、麥粟斛斗的比價。
On the base of var. analysis significance of the experimental treatment, we investigated crop response to water - salt stress regularity, studied the quantity relationship about crop yield and soil water and salt, established a function about them referring to blank and jense water model. conclusions as follows : ( 1 ) the effect of germinating time and rate emergence are different in soil with different salt content, and limited seriously in heavy saline soil
在方差分析確認試驗處理顯著的基礎上，對作物生理生育指標（株高、莖粗、葉片數、花盤直徑、干物質量、葉水勢、
籽實產量）進行統計分析探索作物水鹽響應規律；研究作物產量與土壤水分鹽分聯合作用的定量關系，參照水分的blank加法和jense乘法模型
結構，建立作物水鹽響應模型。
The result shows that by adding artemisia sphaerocephala krasch gum, the quality of blended maize - wheat flour calm be improved, and the rheological and viscoelastic property of dough can he significantly enhanced, so that the viscoelastic property of noodle, the ratio of broken noodle and the turbidity of noodle soup can be reduced, and the noodle is of a smooth taste and a good strength
結果表明，添加沙蒿
籽膠能改善玉米混合粉的粉質，使面團具有良好的流變特性，並能顯著增加面團的粘彈性，從而使面條的粘彈性增強、斷條率降低、糊湯程度減小，面條口感滑潤耐咀嚼。
Inspected from bt cotton planting area of china from 1997 - 2001, due to bt cotton adoption, it ' s estimated that the increment in cotton production is totaly 798 thousand ton, equivalent to 2630 million yuan in output value ( the cotton price is average cotton price of china ). the decrements in pesticides use in these 5 years were respectively 0. 1 ( thousand ton ), 0. 3, 14. 7, 31. 4 and 51. 8
利用以上研究
結果以及1997 2001年全國bt抗蟲棉的播種面積，我們推算出bt棉推廣的總影響，由於該作物的推廣，全國5年累計增加棉花產量79 8萬噸，相當于增加棉花產值26 3億元（
籽棉價格按全國每年的平均價格計算） 。
The results indicated that the following characters were the important roles between any two character groups, plant height, yield per plant, seed coat ratio, yellow degree
結果表明，在性狀組間關聯上起主要作用的是株型性狀中的株高、產量性狀中的單株粒重、品質性狀中的皮殼率和黃
