在有关豌豆栽培技术调查中,发现密度高低对旱地豌豆的增产起着决定性作用,密度的增产效益有时甚至超过磷氮化肥。然而,在定西地区豌豆生产中存在一个突出问题是密度欠佳,不适于高产需要。当地豌豆“密度宜高亦宜低”,高低悬殊,波动很大。按播种量计
In the investigation of pea cultivation techniques, it was found that the density has a decisive effect on the increase of dry pea, and the yield increase of density sometimes exceeds that of phosphorus and nitrogen fertilizer. However, one of the outstanding problems in pea production in Dingxi area is its poor density and is not suitable for high-yielding needs. Local pea “density should be high should also be low,” the level of disparity, a great deal of volatility. According to the amount of seeding
