施用不同品种肥料对籽粒苋生长和鲜草产量的影响

Effects of Application of Different Fertilizers on Growth and Fresh Grass Yield of Amaranthus hypochondriacus

籽粒苋作为粮饲兼用作物,具有较强的抗逆性,近年来在内蒙古五原县引种种植。为了选择适宜籽粒苋栽培的肥料,通过施用不同品种肥料,比较籽粒苋生育期、株高和鲜草产量情况。结果表明:籽粒苋生育期为95~101 d,施用航天恒丰肥料(F2)较沃浩源有机无机复合肥料(F5)和住商复合肥(F7)生育期延长6 d;不同试验处理间株高差异显著,株高最高处理为金正大沃夫特(F4);航天恒丰肥料(F2)处理鲜草产量最高,为116.13 t/hm^2。以获得较高的鲜草产量为目标,航天恒丰肥料是适宜当地籽粒苋种植的肥料。

Amaranthus hypochondriacus is a dual-purpose crop and has strong resistance.In recent years,it has been introduced to cultivate in Wuyuan County of Inner Mongolia.In order to select the suitable fertilizers for cultivation of Amaranthus hypochondriacus,a comparative study was conducted to evaluate the application of different fertilizers on growth period,plant height and fresh grass yield of Amaranthus hypochondriacus.The results showed that the growth period of Amaranthus hypochondriacus ranged from 95 to 101 days;the growth period of Amaranthus hypochondriacus fertilized with′Hangtian Hengfeng′(F2)was 6 days longer than that fertilized with′Wohaoyuan′organic and inorganic compound fertilizer(F5)and′Zhushang′compound fertilizer(F7);there was significant difference in plant height among different fertilizer treatments,and the highest plant height was observed in Amaranthus hypochondriacus fertilized with′Jinzhengda Wofute′(F4);the treatment of′Hangtian Hengfeng′(F2)had the highest fresh grass yield which reached up to 116.13 t/hm^2.When higher yield of fresh grass is given priority,′Hangtian Hengfeng′fertilizer is recommended.
