With the five-elements two times orthogonal gyration combination design, comprehensive technical measures of over 3 750 kg /hm2 production were studied.
Considering the special geological condition and the practical situation,we put forward the corresponding comprehensive technical measures of the reinforce ment and the treatment on the project.
The theories result and comprehensive technique measure is introduced to improve side entry well cementing quantity,annular clearance of slim hole and casing,micro-step hole enlargement technology,slim hole cementing technology and complement are dissertated concretely.
The cause of building crack in water supply and waste water engineering is briefly analysed, and the comprehensive technique measure of controlling the crack is emphatically introduced, such as the design, construction, material etc.
By the monitoring investigation for nine years, the changing law of the slash mouse species are known basically after the catastrophic forest fires, on the basis of these, using the comprehensive technical measure of physics, afforestation, chemistry and ecological control etc, the mouse density was controlled effectively, and the first period project of the forest resources renewal of the forest fires slash are put into effect successfully.
A 8 hm 2 stand of Chinese chestnut fruiting early with high yield was established in 1993.The yield for 4 year old trees amounted to 12 195 2 kg·hm -2 on the average with effective technical measures taken,which is of significance to chestnut production.
Chinese fir(Cunninghamia lanceolata)orchard of 1.5 generation was established in 1985 in Hengfan Forest Center of Linan Zhejiang province,Average output of seed in 1991reached 105kg/hm2 Cone seed rate was 5.7% In 1995 when was the peak fruiting period the average seed output topped 141.5kg/hm2 cone seed rate was 6.3%,which set a record in China
By canopy replacement by high grafting elite breed and integrated measures such as pruning,tending,fertilization,intecropping with grain crops and pest and disease control,low-yield Castanea mollissima of 10-12 years were transformed and their yield was improved from 108.6 kg/hm 2 to 1 260.45 kg/hm 2.The grafted young trees of 2 years fruited 2-3 years ahead of due time.
The purpose of this review is to familiarize the reader with common and rare imaging patterns of chest trauma and substantiate the advantages of MDCT as a screening and comprehensive technique for the evaluation of these patients.
X-ray crystallography is the only method for determining the "absolute" configuration of a molecule and is the most comprehensive technique available to determine the structure of any molecule at atomic resolution.
This paper develops the Power-method, a comprehensive technique applicable to a wide range of query optimization problems under both L∞ and L2 metrics.
This treatise is mainly based on the reseach for improving the effect of bench bla-sting at Dexing Copper Mine.The test work was carried out in 1980~1982 in cooper-ation with Changsha Research Institute of Mining,Dexing Copper Mine and Nan-chang Nonferrous Metallurgical Designing-Research Institute.This paper discusses theeffects of parameters on rock blasting,such as the drilling patterns,short delay interval,specific charge,charged construction,ratio of length of charge to length of stemming,ignition patt...
The analysis of high-yielding soil environmets (including the dynamics of water) which were produced by the comprehensive cultural techniques, the dynamical development of soybean population and the balance of nutrients in roots was carried out in this paper. The results of this investigation showed that the propecties of soil on which soybean yield reached 3750kg/ha were: the content of organic matter ranged from 2.6 to 3.0%, the bulk density ranged from 1.0 to 1.1g/cm3 soil porosity from 56 to 60%, total ...
Multiple techniques for more profits from Phyllostachys pubescens of Bamboo shoot yield purposes were studied: nitrogen fertilizer application, loosening the soil and keeping ratioally mother bamboos. 1. notable results by applying multiple techniques, comparing the control were as following: 185.04 kg per mu of bamboo shoot, 369.39 kg per mu of bamboo, 171.85 yuan per mu of output value than in the control. 2. by nitrogen fertilizer application: the relationship between the amount of urea fertilizer applic...
