紫穗槐生长快,萌芽力强,经2～3次平茬后每墩可发20—30条。一年生紫穗槐每亩产鲜枝叶1000—1500斤,二年生可产2000—3000斤。1000斤鲜枝叶相当于硫酸铵66斤、过磷酸钙15斤、硫酸钾15.8斤。因此,紫穗槐是一种产量大、肥效高的绿肥植物。那么,怎样利用和沤制紫穗槐绿肥呢?下面谈谈这个问题。紫穗槐地上部鲜重中,叶重占50—60％。鲜叶具有氮素含量高、分解较快的优点,我们利用这一优点,进行沤制和利用,方法都很简便。如直接压青,将收割的鲜嫩茎叶,铡碎后,撒入农田翻地作肥。雨季7—10天,夏、秋季15—20天即
Amorpha fruticosa grow fast, strong sprouting, after 2 or 3 stubble per pier can be made 20-30. Annual Amorpha fruticosa per acre fresh leaves 1000-1500 pounds, perennial can produce 2000-3000 pounds. 1000 pounds of fresh leaves equivalent to 66 kg of ammonium sulfate, 15 kg of superphosphate, potassium 15.8 kg. Therefore, Amorpha fruticosa is a green manure with large yield and high fertilizer efficiency. So, how to use and control of purple acacia green manure? Here to talk about this issue. Amorpha fruticosa fresh weight in the upper leaves accounted for 50-60%. Fresh leaves with high nitrogen content, the advantages of faster decomposition, we take advantage of this advantage, the system and utilization, the method is very simple. Such as direct pressure on the green, will harvest the fresh stems and leaves, crushed, sprinkle into the farmland turn fat. Rainy season 7-10 days, summer, autumn 15-20 days that is
