To study the effect of soil moisture on growth and dry matter accumulation of rice in cold region,controlling water treatments(CWT) for the two rice varieties(Shangyu 397 and Suijing 3) at-30 to-35 kPa and-60 to-65 kPa of soil water potential were carried out during tillering stage,panicle initiation stage,1-10 days after heading,11-20 days after heading,respectively.
The effects of TDZ(Thidiazuron)on the quality of grape varieties 'Jingya' and('87-1')in cold area indicated that the fruit weight and soluble solid were increased by TDZ treatment significantly and acid degree declined trendly.
Aimed at the dominant of natural resources in boli county, it proposed some creative measure about industrialization of better rice in cold field such as rely on science and technology, optimize breed structure and arrangement of region, increase the propagable dynamism about culture technics of better rice,rely on strategy of brand, promote industrialization of better rice, develop agriculture of order, connect the yield, processing and market etal.
By means of researching the relation about variety and thin planting, clarified the thin planting in cold field should select he variety which has mid-maturation or middle early variety, the higher stooling, the bigger ear of grain and the stronger resistance.
The close agreement of the results suggest the Taylor's series method may be applied to solve many cold region's engineering problems to account for the variability of input parameters.
in the deep cold region of Heilongjiang province in China and the cold tolerant larvae ofDendrolimus punctatus Walker in southern China.
Advances on bioremediation of oil-contaminated soil in cold region
A large area of moraine sediments and cryogenic weathering products, formed by glacial action and a cold environment, are the main source of aeolian sand in the high and cold region of the Qinghai-Tibetan Plateau in China.
Neither bull's eye map homogeneity nor contrast between a hot and a cold region were affected by depth-dependent collimator response or finite spatial resolution.
Based on the test results in arid and cold area of the northwest Shanxi, the hybrid poplar trees takingPopulus cathaysna as their female parent could be selected for afforestation, such asP.
Most pyogenic liver abscesses appear to be 'not' in a 67Ga-citrate study; rarely, a 'warm' or 'cold' area may also be seen.
We present a case of juxtaglomerular cell tumor in which renal scintigraphy revealed a well-defined cold area in the hilar region of the left kidney.
When the scintigraphic pattern did not fit either of the two patterns or when the presence of the cold area between the bone fragments could not be judged with certainty, it was called indeterminate (group 3).
All 4 patients with a large cold area evidenced collapse within I year despite good recovery of the weight-bearing surfaces immediately after operation on conventional radiograms.
The results indicate that the DRFs constructed can be used for mapping and estimating the cost of corrosion losses in cold regions even when the cold places are not directly involved in the test program.
The proportion of hot and cold regions in the polar solar corona during 1957-2002
It is shown that the distribution of the temperature in the sample can have a point of inflection that separates the "hot" and "cold" regions.
Possible evolutionary steps in adaptation to cold regions are discussed.
Nonlinear analysis for the coupled problem of temperature and seepage fields in cold regions tunnels
