Different Cultivation Way To "Guiza4" Rape Output And Character Influence

Effect of cultivation way on Rapeseed Guiza 4 yield and characterIn transplants under the condition to use three factor two grouping combination experiment and uses three Yuan two return orthogonal combination design under the direct seeding condition the rape to conduct the research to "guiza 4", has analyzed each cultivation factor to the rape "guiza 4" the output and the character influence effect, according to the above formulates the high production cultural technique optimum composition.Experiment one result to indicate that ,The ridge culture, the width line, spurt under the pp333 single factor function or the together function, the rape seedling stage number of leaves, the adult plant dry matter heavy, NR activity, the root system vigor and the flowering season only photosynthesize the speed all to have the enhancement; Spurts pp333 to " guiza 4" the output, No. of pools per plant, number of pods reaches extremely remarkable . The ridge culture to the No. of pools per plant, number of pods, 1000-seeds weight influence reaches extremely remarkable .The width line to the No. of pools per plant, number of pods, the angle number of seeds influence reaches extremely remarkable . Processes 2 (ridge culture + width line + to spurt PP333) 174.5 kg /666.7 m~2, compares with the comparison, the production increase scope achieves 26.1%, for most superior combination.Experiments two results to indicate that ,The density is affects the output the leading factor. The density to the rape output, number of pods, No. of first branch reaches remarkable ., is remarkable to the host inflorescence silicle number influence; Pursues Shi Fu to the rape output. No. of first branch influence is extremely remarkable; Three factors to the number of seeds, 1000-seeds weight influence are not all obvious; Three factor correlations are not remarkable to the rape output and each economical character influence.To three factor optimum composition: In the density is 8323 /667 m~2 spurts pp333 for 755 mg/ kg, pursues Shi Fu the fat quantity for 23 kg/667 m~2, may obtain 218 kg/667 m~2 output.
