在中性紫色土上,甜橙生长结果期NK 肥配施能促进植株良好生长发育,显著提高产量,对改善果实品质,提高果实的贮藏性亦有一定的作用。7年生枳砧锦橙按NK 肥1:0.75即N400克、K_2O300克配施,植株营养水平较稳定。单施N 降低了对P,K 及B 等元素的吸收,单施K 抑制了Mg,Mn 元素的吸收。配施磷肥的效果不显著。
On neutral purple soil, the application of NK fertilizers during the fruiting stage of sweet orange can promote the good growth and development of plants and significantly increase the yield, which also plays an important role in improving fruit quality and improving fruit storage. 7-year-old Poncirus ancestral orange according to NK fertilizer 1: 0.75 that N400 grams, K_2O300 grams with facilities, plant nutrition levels more stable. Single application of N reduced the absorption of P, K and B elements, K inhibited the absorption of Mg and Mn. With phosphate fertilizer effect is not significant.
