一、材料和方法选用三年生植株所产饱满健康种子作试验用种,在播种前用58％瑞毒霉锰锌可湿性粉剂300倍液消毒处理种子30分钟。试验设4个处理:1.地膜覆盖凸墒栽培,底肥量每亩2500公斤;2.地膜覆盖凸墒栽培,底肥量每亩5000公斤;3.地膜覆盖平墒栽培,底肥量每亩2500公斤;4.山草覆盖凸墒栽培,底肥量每亩2500公斤(对照)。设三次重复,小区面积7.2米~2,株行距5×5厘米。对照在6月施一次追肥,每亩用量2500公斤。二、结果与分析 (一)不同底肥量及墒形对三七种苗产量的影响
First, the material and methods Selection of three-year-old plant produced full of healthy seeds for the test species before sowing with 58% refective mold Mn-Zn WP 300 times disinfect seeds for 30 minutes. Experiment set up four treatments: 1. Mulch moisture cultivation, the amount of base fertilizer 2500 kg per acre; 2. Mulch moisture cultivation, base fertilizer 5000 kg per acre; 3. Mulch cultivation of plastic film, the base fertilizer 2500 kg per acre ; 4. Mountain cover convex moisture cultivation, the base fertilizer 2500 kg per acre (control). Set three repetitions, the plot area of 7.2 m ~ 2, spacing of 5 × 5 cm. Control applied fertilizer in June, the amount of 2500 kg per mu. Second, the results and analysis (A) of different base fertilizer and moisture content of Panax notoginseng seedlings yield
