摘要
籽粒苋耐干旱、生长快、萌蘖力强、饲用效果好、用途广等优良特性，决定了其能作为重要的生态位资源在林地、果园隙地种植，实现林（果）—牧良性循环。调查分析表明：籽粒苋能在地势平缓的低丘、岗地的林地、果园隙地种植，但其生长随林（果）木的年龄、高度、郁闭度而有差异，以幼林（果）地种植并以茎叶利用为好；林地、果园间种籽粒苋能有效地改善林地小气候、改善土壤结构，并在一定程度上调节土壤水分状况，有效地增加土壤中Ｐ、Ｋ含量，改良土壤；利用林地、果园种植籽粒苋，并利用籽粒苋饲喂畜禽，是降低成本，提高林地、果园经济效益，实现长、中、短效益结合的有效途径。
Grain amaranth is a good forage crop and has the characteristics of drought tolerancerapid growth and strong sprouting. All these make it an important ecological niche resource. The survey analysis shows the Grain amaranth inter-planted in the forest or orchard which form the forest(orchard)-stock raising circle can grows well but its growth varies with the tree's age, tree height and the crown density. So inter-planting it in young plantations is most suitable. Inter-planting Grain amaranth can improve the microclimate and soil structure. It can also adjust the soil moisture, increase P and K contents, improve soil quality in some degree. So inter-planting Grain Amaranth and use it as a forage crop is a good way to cut cost increase economic benefit both at present and in future.
