马铃薯与甘兰间作套种,是河北北部高寒区应用的栽培方式之一。它采用垅作形式,马铃薯长在垅上,甘兰栽到垅沟,在多风低温的早春,为甘兰创造了较为良好的生长环境。对于垅上的马铃薯,由于不直接浇水,可以有效地避免土壤板结,又为马铃薯的块茎发育提供了良好的土壤条件。由于两者共生期短,通风透光,空间利用更趋合理,发挥了土壤生产潜力,提高了经济效益,亩产值可达4000元以上。 1.准备工作 首先,要备足肥 Potato and intercropping intercropping, Hebei Province, northern part of the high cold areas of cultivation methods used. It is used as a form of crop, the potato grows on the 垅, planting cabbage 垅 ditch, windy and low temperature in early spring, for the kanlan to create a more favorable environment for growth. For the potatoes on the top, soil compaction can be effectively avoided because of no direct watering, and good potato conditions for tuber development are also provided. Due to their short symbiosis, ventilation and light, the space utilization is more reasonable and the potential for soil production has been brought into play and the economic benefits have been raised. The output value per mu can reach more than 4,000 yuan. 1. Preparation First of all, to prepare adequate fertilizer
