1整地,做畦整地需要精细,深耕20~30cm,细耙几遍,确保土壤上松下实,通气性好。要根据土壤的肥力和养分状况确定施肥量,一般生产100kg花生,需要吸收纯氮6kg、五氧化二磷1kg、氧化钾3kg,其中约1/2氮来自根瘤菌固氮。施肥以有机肥为主,化肥为辅。施土杂肥15.0~22.5t/hm2,并与化肥相结合在整地时深施和匀施。结合整地做畦,畦高10~12cm,畦底深80~90cm,畦面平,采用打孔播种,选用优质液体地膜进行喷洒。
A site preparation, land preparation and planting need fine, deep plowing 20 ~ 30cm, fine rake several times, to ensure that the soil is pine solid, good ventilation. According to soil fertility and nutrient status to determine the amount of fertilizer, the general production of 100kg peanuts, need to absorb 6kg of pure nitrogen, phosphorus pentoxide 1kg, 3kg of potassium oxide, of which about 1/2 nitrogen from rhizobium nitrogen fixation. Fertilizer to organic fertilizer, supplemented by fertilizer. Shi Tu Shi Fei 15.0 ~ 22.5t / hm2, and combined with fertilizer in the preparation of deep soil and even facilities. Combined with soil preparation to do 畦, 畦 high 10 ~ 12cm, 畦 bottom 80 ~ 90cm, 畦 surface flat, the use of drilling drilling, selection of high-quality liquid film for spraying.
