旱作地区农田施用畜肥后对主要的粮食作物都有显著的增产效果 ,其增产率 16 18%— 45 6 2 %。不同畜肥的肥效为羊圈肥 >猪圈肥 >马圈肥。不同粮食作物每公顷施用 1 5t畜肥分别增产 :羊圈肥增产春小麦 2 89 5kg·hm- 2 、豌豆 44 4kg·hm- 2 、马铃薯鲜薯 2 910kg·hm- 2 ;猪圈肥增产春小麦 2 6 7kg·hm- 2 、豌豆 15 6kg·hm- 2 、马铃薯 2 42 2 5kg·hm- 2 ;马圈肥增产春小麦 6 6kg·hm- 2 、豌豆 15 6kg·hm- 2 、马铃薯 1830kg·hm- 2 。水分利用率分别提高 :春小麦 19 0 5 %— 80 95 %、豌豆 17 78%— 5 3 33%、马铃薯 49 7%— 79 2 9%。
The application of livestock manure in dry land areas showed significant stimulation effect on major grain crops, with an increase rate of 16 18% -45 6 2%. The effect of different livestock manure is the sheep fat> piglet fat> stump fat. The application of 15t animal manure per hectare of different food crops increased separately: the yield of sheep was increased by 2 89 5 kg · hm-2 for spring wheat, 44 4 kg · hm-2 for pea and 2 910 kg · hm-2 for fresh potato; · Hm-2, peas 15 6kg · hm-2, potato 2 4225kg · hm-2; stoma yield 6 66kg · hm-2 of spring wheat, peas 15 6kg · hm-2, potato 1830kg · hm-2. The water use efficiency increased respectively from 19 0 5% to 80 95% for spring wheat, 17 78% to 53 33% for pea and 49 7% to 79 2 9% for potato.
