为了寻找低产区谷子增产途径和經济利用現有化肥,根据一般禾谷类作物的种籽仅能供給发芽后10~20天营养的特点,从1963年起,开始进行谷子氮素种肥的研究,幷于1964年在谷子样板田中普遍采用这一措施。两年来,在旱薄地上进行谷子施肥期的試驗,以亩施农家肥3,000斤为基础,再施用1斤氮素作为种肥,即硫銨5斤/亩或硝銨3斤/亩,可增产8.1~12.6%,如(表1)。
In order to find ways to increase the yield of millet in low-yield areas and to use the existing chemical fertilizers economically, according to the fact that the seeds of general cereal crops can only provide nutrition for 10 to 20 days after germination, since 1963, In 1964 in the millet template Tanaka commonly used in this measure. In the past two years, the trial of millet fertilization on dry land was conducted on the basis of 3,000 kg of mu of farmhouse fertilizer and 1 kg of nitrogen as the seed fertilizer, 5 kg / mu of ammonium sulphate or 3 kg / mu of ammonium nitrate Increase 8.1 ~ 12.6%, as (Table 1).
