In this experiment, We selected the four major controlled factors whichwere the application of N and P_2O_5 fertilizers, sowing norm and the dateof first water as independent variables, and the protein content, starch contentand perunit area yield for brewer's barly as aim function's four elementquadratic regression equations of the four factors with each aim functionwas built up respectiv ely through the study of the relationships betweenthem. On this basis, after the single and double frequency analysis, reducing indimention for optimum value and analysis to eaeh major factor and so on,the extent and change tendency of the four major factors that affected theprotein and starch contentof brewer's barley was discussed. the modles of theoptimum agricultural measures having protein content in 8.96 + 1.34% andstarch content in 56.76 + /3.55% in the grain were obtained. The modle with400kg and above for yield per mu, 10% and under for protein content in thegrain was as this: per mu application of N was 8.33 to 9.18kg, per mu applicationof P_2O_5 7.38 to 8.28kg, sowing norm per mu 285.2 to 307.0 thousand grains andthe date of first water 2.39 to 3.1 leaves.

本文通过对可控主效因子施N量,施p_2o_5量,播种粒数和头水叶龄为自变量,以蛋白质含量、淀粉含量和产量为目标函数的研究,分别建立了四项主效因子与目标函数的四元二次回归模型。在此基础上,经过单频数分析、双频数分析,降维求优和主因子解析等,分析了四项主效因子对蛋白质和淀粉含量影响的重要程度及变化趋势。得到了籽粒蛋白质含量(78.96±1.34)%、淀粉含量(56.75±3.55)%的优化农艺措施组合;获得了亩产≥400公斤、蛋白质含量≤10%的优化农艺措施组合为:亩施纯N8.33—9.18公斤,亩施P_2O_27.38—8.28公斤,亩播粒数28.52—30.7万粒,头水叶龄2.9—3.1叶。

Since the first water quality mathematical model was presented in 1925, through nearlg seventy years study and develop, many different models have been prosented. The process of studying this models in abroad can be devided to four periods, calculation method has been developed from one-dimension to three-dimensions. Definite models have been thorougly studied and applied in home. Now the two developing directions of models are continuously using new technique to improue existing models and build up and apply indefinite models.

自1925年建立第一个水质数学模型以来,经过近七十年的研究与发展。现在,已提出了许多不同的模型。国外对水质数学模型的开发研究可分为四个阶段,计算方法由一维发展到三维。国内已在确定性模型方面作了较为深入的研究与应用。目前,水质数学模型有两大方向:(1)应用新技术不断改进已有模型;(2)建立和应用非确定性模型。

After several years study。We found that the survival rate of plantution from di-rect seeding was very low,only 14/0% in JiLantai and 14.1%in Xin Jiang. Under the condi-tions of first water,the survival rate of plantation by tree planting were:first years value was43.1% and second years value was 48.7.But for container seedling,they were 84.4% and66.7% respectively in rain season(no irrigation)。During dry seasons,if desiccant had beenadded in container,the first years survival rate and second...

After several years study。We found that the survival rate of plantution from di-rect seeding was very low,only 14/0% in JiLantai and 14.1%in Xin Jiang.

Results showed tbat the solution of effect matrix was plantationby container seedling,which was guided by multigoals and multisituations.Multigoals: first years survival rate of seedling,second years survivai rate of plantation,height,stem diameter at ground level,crown area and investment cost.Multisituations: JiLantai.Xinjiang and Gansu. Considering every method of planting,the plantation by container seedling was an effec-tive technique for rejuvenation and regeneration of cakcayr forest.

在多年试验研究和广泛收集借鉴他人研究的基础上,利用灰色系统中多目标、多种局势条件下,灰色决策理论,对梭梭容器苗造林,直播造林和实生苗造林进行灰色决策。结果证明,在多目标(包括造林成活率;保存率、苗木生长状况、投资成本),多对策(兰泰、新疆、甘肃)的局势下,效果矩阵最优解都为梭梭容器苗造林,从而反映出梭梭容器苗造林是恢复梭梭林的最佳技术。
