When the yield of sunflower exceeds 300 kg/hm 2,it is recommended to be an optimization agronomic programme that 75～100.95 kg/hm 2 pure N fertilizer,69～82.5 kg/hm 2 pure P 2O 5 fertilizer,45 000～49 485 plants/hm 2 in density and N∶P 2O 5=1.1∶1～1.2∶1 are taken.
The author proposes high Fe raw mix proportioning programme, KH 0.92～1.03, C_4AF≥18 per cent, C_3S≥ 55 per cent, C_2S≤16 per cent and summarizes experience with reasonable air, quick burning and low cooling and so forth which should be paid attention to when manufacturing highway cement by shaft kiln.
The result of superplastic tensile test in I programme indicates that the specimens present superplasticity in the range of temperature from 390℃ to 470℃ and strain rate from 1. 1× 10~1s~1 to 1.1×10 2s1, in which the elongation can reach 102. 4%~ 14.9. 5%.
With an aim to identify potential silkworm races/breeds specific to thermotolerance for their effective utilization in breeding programme, 15 selected polyvoltine silkworm races were studied for their thermotolerance behaviour.
The identified putative markers are being used to develop DNA marker to be used in evolving thermo-tolerant silkworm breeds using marker-assisted selection programme.
The XENGEN programme was applied to data processing; the data were used to 0.22 nm.
The structure was detcrmined by the difference Fourier method and refined using X-PLOR programme.
Based on these results, a PCR programme was created to genotype animal individuals in different pig breeds at FSW locus and polymorphism of FSHP gene was analyzed.
