在四十年代,就有不少学者通过试验证明花生不但能用根吸收养分还能用果针和幼果吸收养分。1951年贝利在美国佐治亚洲试验,当土壤含钙量极低时,在花生开花盛期每亩撒施石膏74市斤,能使小西班牙品种增产27%,NC 蔓生种增产近二倍,普通型丛生种增产三倍,普通型蔓生种增产近四倍.在1971年有人用示踪元素研究花生养分的吸收和运转,用盆栽试验将 Ca45施入结荚区土中,结果有88.33%的 Ca45积累在荚果中,如将 Ca45施入根区土中,有66%的 Ca45在叶片内,而13.8%转入荚果中。更进一步说明了前人的试验结果。1974年江苏省徐州地区进行花生施用石膏试验,在23个典型试验的64个对比处理中,增产的占70%,增产幅度为1.2—49.3%,每斤石膏增产荚果0.1
In the 1940s, many scholars showed that peanuts can not only absorb nutrients with roots but also absorb nutrients with fruit needles and young fruits. 1951 Bailey in the United States, Georgia test, when soil calcium content is extremely low, in the flowering peanut sprinkle 74 kg per acre, can make small Spanish varieties increased 27%, NC vine species nearly tripled, Common type of tussah three times the production of ordinary vine nearly four times the increase in production in 1971 tracer element was used to study the absorption and operation of peanut nutrients, pot experiments Ca45 applied to the pod soil, the results were 88.33% Ca45 accumulated in the pod, such as Ca45 applied to the root zone soil, 66% of Ca45 in the leaves, and 13.8% transferred to the pods. Further illustrates the results of previous experiments. In 1974, the peanut application gypsum test was conducted in Xuzhou, Jiangsu Province. In the 64 comparative treatments of 23 typical experiments, the yield increase accounted for 70%, and the increase rate was 1.2-49.3%. The yield per pound gypsum 0.1
