Alleviating Effect Of Different Cultivation Modes On Peach Continuous Cropping Obstacle

To investigate the palliative effect of different cultivation modes on peach continuous cropping obstacle,one-yearold 'Xiahui 5' were used as experimental subjects in our current experiment.We used field trials in order to study different cultivation modes into replant disease on growth of peach seedlings,soil phsical and chemical properties.As for the results of this experiment,they can be summarized as follows:1.Effects of different cultivation patterns on the reproductive and vegetative growth of peach seedlings under continuous cropping obstacles.Compared with the other treatments in the continuous cropping soil,Root restriction cultivation played a significant role in promoting the reproductive and vegetative growth of peach seedlings.The length and diameter of primary shoot,plant height,trunk diameter of T3 were 1.10 times,1.03 times,1.02 times and 1.03 times of CK,1.52 times,1.75 times,1.63 times and 1.79 times of T1,1.70 times,1.59 times,1.50 times and 1.71 times of T2.In crown diameter,T3 was lower than CK,but the difference was not significant.The other two treatments were lower than the above two treatments in varying degrees.The content of photosynthetic pigment in T2 was significantly higher than other treatments.The production and quality was increased significantly in T3,the peach production of T3 was lower than CK,but the quality of peach was higher than CK2.Effects of different cultivation modes on soil under continuous cropping obstacles.Different cultivation modes had no significant effect on soil water content,total potassium,available phosphorus and ammonium nitrogen.Root restriction cultivation significantly improved multiple indicators of continuous cropping soil.The soil pH value,organic matter content,total phosphorus content and available potassium content of T3 were 1.02 times,2.30 times,1.33times and 2.12 times of T1,1.12 times,1.40 times,1.50 times and 1.76 times of T2.The activities of acid phosphatase and catalase were maintained at the same level between CK and T3.The results showed that there was no significant difference between CK and T3,meanwhile,the soil pH value and organic matter content of T3 were slightly higher than CK.Intercropping and ridge cultivation mode had no significant remission effect on continuous cropping obstacle,while root restriction cultivation mode efficiently reduced the adverse effect on peach seedling in continuous cropping soil.Root restriction cultivation mode promoted peach seedling growth,soil physical and chemical properties of continuous cropping soil as well.Peach seedling,physical and chemical properties of continuous cropping soil had no significant difference with CK,some indicators were even higher than CK.
