花生首批花所结的果实,因为成熟早,收获时已经在土内变质甚至腐烂,影响了产量和品质。为了延缓初期花下针的时间,摸清早期花晚入土增产荚果的原因,我们于1980年和1981年配合作物栽培进行了试验,其方法是在播垄上设置一种胶片作屏障(见题图),以控制早期果针入土。于6月19日放置7月12日撤除。 The first fruits of peanut bear the fruit, because mature early, harvest has been deterioration in the soil or even decay, affecting the yield and quality. In order to delay the initial time spent on flowers and to find out the reasons for early yield increase of early pods, we conducted experiments with crop cultivation in 1980 and 1981 by setting a film on the sowing ridge as a barrier Figure) to control the early needle into the soil.
