豌豆是一种需磷较多的作物,据我们在右玉县盆儿洼大队的试验,豌豆施用磷肥不仅有利于根瘤的形成和提高固氮能力,而且有利于营养生长和生殖生长,增产效果显著。方法是将磷肥与农家肥混合堆沤,播种时随种子溜入犁沟。亩施过磷酸钙15—20斤,株高比对照增加10—30厘米,茎粗增加0.1厘米左右,叶片数增加2—4片,荚数增加2—3个,株粒数增加5—12粒,千粒重增加10—23克,每株有效根瘤增加20—30个,根瘤重增
Peas are a kind of crops that need more phosphorus. According to the experiment of Pierwa Valley Brigade in Youyu County, pea application of P fertilizer is not only beneficial to nodule formation and nitrogen fixation, but also beneficial to vegetative and reproductive growth with significant increase in yield . The method is to mix phosphate fertilizer and farmyard manure, sowing with seeds into the furrow. Acres applied 15-20 pounds of calcium phosphate, plant height increased by 10-30 cm compared with the control, stem diameter increased by about 0.1 cm, the number of leaves increased 2-4 tablets, pods increased 2-3, the number of strains increased 5-12 Grain, grain weight increased 10-23 grams, 20-30 effective nodules per plant, nodules increased
