1产地环境1·1产地环境条件应符合NY/T391-2000的要求。1·2土壤条件高粱对土壤的适应范围较广,但土层深厚、疏松、保水、保肥能力强的土壤更适于种植高粱。高粱要求微酸性至微碱性土壤,pH值在6.5~7.5较为适宜。1·3茬口安排高粱对茬口要求不严格,玉米、大豆、花生等茬都适合,?
1 Origin Environment 1.1 Origin Environmental conditions should meet the requirements of NY / T391-2000. 1.2 Soil conditions Sorghum adapts to a wide range of soils, but soil with deep, loose, water-retaining and fertilizer-retaining capacity is more suitable for growing sorghum. Sorghum requires slightly acidic to slightly alkaline soil, pH value of 6.5 to 7.5 is more appropriate. 1.3 Crop arrangement sorghum stubble requirements are not strict, corn, soybeans, peanuts and other stubble are suitable?
