The Influence Of Herbicide To Oil Flax Growth

Oil flax is a main oil crops, but oil flax field of chemical weed control technique is far from complete. This experiment adopts single factor randomized block design, green cycling, MCPA sodium salt, acetochlor, trifluralin, speed, taking on and can efficiently cover grass herbicides such as pot experiment, the preliminary study of these herbicides on oil linen growth and to simulate the influence of the weed control effect, the results are as follows:1. This study selected herbicide of different concentration, the germination rate of oil flax plant height, stem and branch Numbers per spike, plant fruit number, such as morphological indexes has certain influence, generally characterized by the increase of the concentration of herbicide treatment, the determination of indexes in varying degrees of decline. The morphological indexes for the rape and millet weeds simulation the influence of also show a similar trend.2. The different concentration of herbicide treatment of oil flax chlorophyll, soluble sugar, nitrate reductase, peroxidase and so on physiological indexes is not the same, the influence of different physiological indexes with different change trend. With the increase of the concentration of herbicide treatment, the oil of linen chlorophyll content, nitrate reductase activity a trend of decrease, soluble sugar content and peroxidase activity was increased after the first reduce the change trend of these trends reflect the herbicide concentrations increased oil linen for damage, but also reflects the oil linen under adversity stress ability of art.3. This test can get preliminary results:in the trifluralin m2 (2250 ml/h), MCPA (1.125 kg/h m2), acetochlor m2 (900 ml/h), speed (0.180 kg/h m2) dosage, but in the case of ensure the safety of oil flax, achieve relatively good weed control effect.4. Due to the limitation of time and conditions, the test has not been research still has a lot of, the content of the precaution of, this paper reference field trials, the test results only in the field of widespread application, will need to be further studied.
