Study On The Law Of Distribution And Translocation Of Nutrition And Its Dynamic Model Of Absorption With Different Varieties Spring Wheat

With mengmai no.36 and other five varieties, we have studied systematically the changing law of concentration, absorption, accumulation and distribution of N. P. K. S. Ca. Mg. Fe. Mn. Cu. Zn at different growth periods in spring wheat. The consumption coefficients and productivity of N. P. K. S. Ca. Mg. Fe. Mn. Cu. Zn and the amount of absorption to produce 100 kg grain were made clear. The absorption dynamic model of ten nutrition of six CV. spring wheat were established. Through the model, we calculated the greatest amount of ten nutrition uptake and the fastest absorption rate and their appeared time. The absorption, distribution and dislocation of nutrition of different spring wheat are different. The concentration, amount of accumulation, the greatest amount of uptake and the fastest absorption rate and their appeared time are significantly different among nutrition.
