冀东地区属于暖温带、半湿润的季风型大陆性气候。年平均气温10.5—11.5度,降水主要集中在7、8月份。土壤类型属沙性土壤,土壤pH值为中性或弱碱性,适于黑花生的种植。一、播前的准备工作1、精耕细做。一般在秋后至结冻前深翻耕地,耕深30厘米以上,以打破犁底层,增加土壤的通透性,破坏害虫的生存环境;春后再浅耙一次,耙深13厘米,将地耙平耙细,使土地平整。结合冬耕,要在耕地前亩撒施17-11-17有机肥50公斤或农家肥2500—3000公斤,基肥硼125—200克,免深耕200克兑水100千克喷施地表
Jidong is a warm temperate, semi-humid monsoon-type continental climate. The annual average temperature of 10.5-11.5 degrees, precipitation is mainly concentrated in July and August. Soil type is sandy soil, soil pH value is neutral or weakly alkaline, suitable for planting black peanut. First, preparation before sowing 1, intensive cultivation. Generally in the autumn after the deep frost heaved tillage, cultivation depth of 30 cm or more, in order to break the plow floor, increase the permeability of the soil, destroy the living environment of pests; and then a shallow rake after spring, rake depth 13 cm, Rake flat rake thin, so that the formation of the land. Combine with winter tillage, before planting acre 17-11-17 50 kilograms of organic fertilizer or peasant 2500-3000 kilograms of base fertilizer 125-200 grams of boron, 200 grams of deep plowing to repel water 100 kg Surface
