紫穗槐用途广,适应性强,种植后收益快。在一般情况下,一年生条很少开花结实;二至三年生的粗壮枝条结籽最多,且籽粒饱满。因此需要在头一年秋天选留母树。如果任母树自然生长结实,往往因枝顶枯损,促使枝条发出很多小果枝。果穗小,且粒数少,种子数量少,质量低。我们在一九七七年三月十二日对留种紫穗槐母树进行了不同长度的打尖试验,同年九月六日调查,增产效果显著,见下表。 Amorpha fruticosa wide use, strong adaptability, fast profit after planting. In general, annuals rarely inflorescences; stalks of two to three years produce the most seeds and plump seeds. Therefore, we need to choose the mother tree in the autumn of the first year. If any mother tree grow naturally strong, often due to the branches of the branches, causing the branches to issue many small fruit branches. Small ears, and fewer grains, fewer seeds, low quality. On March 12, 1977, we conducted a variety of spike tests on the remaining Amorpha fruticosa trees. After a survey on September 6 of the same year, the yield-increasing effect was remarkable. See the table below.
