以生物菌肥和桃苗为试材,通过土壤检测和测量桃苗的生长,研究了生物菌肥对老桃园土壤和再植桃苗生长的影响。结果表明:每株浇灌2亿个·mL~(-1)光合菌剂600mL、2亿个·mL~(-1)光合菌剂300mL和3亿cfu·g~(-1)木霉可湿性粉剂1 500mL放线菌增幅较大。2亿个·mL~(-1)光合菌剂600mL和2亿个·g~(-1)木霉菌300g的速效钾含量增幅较大,2亿个·g~(-1)木霉菌300g能增加有效磷含量,3亿cfu·g~(-1)木霉可湿性粉剂1 500 mL的全氮含量有一定的增加,2亿个·mL~(-1)光合菌剂300mL全钾增幅较大。2亿个·mL~(-1)光合菌剂300mL和3亿cfu·g~(-1)木霉可湿性粉剂750mL对主干的增粗最明显而且也有利于三主枝伸长。侧重于桃苗生长情况,建议选用2亿个·mL~(-1)光合菌剂300mL。
Using bio-fertilizer and peach seedlings as test materials, the effects of biological bacterial fertilizer on the growth of old peach soils and the replanting of peach seedlings were studied through soil testing and measuring the growth of peach seedlings. The results showed that 200 mL · mL -1 of photosynthetic bacteria, 200 mL · mL -1 of photosynthetic bacteria and 300 mL cfu · g -1 of Trichoderma Actinomyces 1 500mL powder larger increase. The available potassium content of 200 million mL · mL -1 photosynthetic bacteria 600 mL and 200 million g · -1 Trichoderma 300g increased greatly, 300 g of 200 million g · -1 Trichoderma Increasing the content of available phosphorus increased the total nitrogen content of 1 500 mL of 0.3 billion cfu · g -1 Trichoderma WP, and the increase of 300 mL total potassium of 200 million mL · mL -1 photosynthetic bacteria Big. The amount of 200 mL · mL -1 photosynthetic bacteria 300 mL and 300 mL cfu · g -1 Trichoderma WP 750 mL was the most significant to the trunk and was also beneficial to the elongation of the three main branches. Focus on the growth of peach seedlings, it is recommended to use 200 million · mL -1 photosynthetic bacteria 300mL.
