花生生产实践证明:花生根上长有根瘤菌,能吸收和固定空气中的氮。这种根瘤菌长的多、长的肥大,花生植株得到的养分就充足,花生果就能增产。然而实践又证明,要想叫花生根部的根瘤菌长的多、长的粗大,应采用如下办法: 1.深耕碎耙。播种前,土壤深耕30厘米以上,细耙2～3次,浅犁一次,耙平耙碎,作畦种植,有利于根系生育。 2.根瘤菌拌种。据调查,花生种子用根瘤菌拌种的比不用根瘤菌拌种的植株根瘤菌生得多,长得好。 3.施足基肥。播种时每667米~2施农家肥(腐熟好的)4000千克、尿素3～4千克、磷肥20千克。
Peanut production practice has proved that: peanut rhizobia long roots, can absorb and fix the nitrogen in the air. This rhizobia longer, long hypertrophy, peanut plants get enough nutrients, peanut fruit can increase production. However, practice has proved that, in order to peanut root rhizobia to be called the long, long and coarse, the following methods should be used: 1. Deep plowing rake. Before sowing, soil plowing more than 30 cm, fine rake 2 to 3 times, a shallow plow, harrow flat rake broken, planting, cultivation is conducive to root growth. Rhizobium seed dressing. According to the survey, peanut seed dressing with rhizobia than rhizobia seed dressing plant Rhizobium much health, grow well. 3. Shizujifei. Sowing every 667 meters ~ 2 farmers fertilizer (maturity) 4000 kg, urea 3 to 4 kg, 20 kg of phosphate fertilizer.
