Abstract:
Taking garlic as test material,in order to alleviate continuous cropping obstacle of garlic in Zhongmou,starting from the regulation of soil nutrient balance,conventional fertilization as CK(CK),conventional fertilization+anti cropping agent as T1 treatment,conventional fertilization+zinc sulfate 22.5 kg/hm2+ammonium molybdate 0.45 kg/hm2 as T2 treatment,conventional fertilization+humic acid 900 kg/hm2 as T3 treatment,conventional fertilization+gypsum 300 kg/hm2 as T4 treatment.The results showed that,the best effect of relief continuous cropping obstacle of garlic was T3 treatment,compared with the control output increased by 10.36%,reached significant level,the pH value of the soil was 8.32,organic matter content reached 1.69%,the content of Mo,Zn,available N,available P and available K was also significantly improved,the activity of soil phosphatase,catalase and urease increased significantly,bacteria and actinomycetes in soil was increased,the quantity of fungi was decreased,so that the three bacterias ratio was more reasonable,the chlorophyll content and antioxidant capacity of plants was also significantly improved,so the photosynthetic efficiency and resistance of paints increased.
