摘　　要：本试验测定了２５℃以下，不同浓度山楂汁的流变曲线。结果表明：山楂汁为牛顿流体。通过回归分析，得到了浓度或温度对山楂汁粘度影响的数学模型和浓度。Influence of the coordinative effects of variety and cultivation method on cotton growth and yield of the improved 3-1 pattern cotton-wheat sequential cropping were studied .The results indicated that various varieties adopting the same cultivation method had identical growth tendency before squaring,but the same variety adopting different cultivation methods had great different growth tendencies .After squaring transplanting cotton seedlings raised in nutrition pot and muslching with plastic film favored cotton plant growth and yield formation of medium mature varieties,and also favored the early stage plant growth of mid-early mature varieties.But the later stage growth was slow ,yield deereased and the ratio of summer bolls to autumn bolls was out of balance.the medium mature varieties by direct seeding grew slowly and the ratio of summer bolls to autumn bolls was out of balance,boll weight,lint percent age and yield were low.However,direct seeding favored mid-early mature variety development ,the ratio of summer bolls to autumn bolls was suitable,yield was high comparatively.
