以江苏省南通地区主栽草莓品种‘红颊’为试材,研究不同施用量的石灰氮对大棚栽培草莓的影响。结果表明,与施用尿素相比,石灰氮在防治根结线虫、抑制杂草生长、提高果实品质和产量等方面作用明显,且随着施用量增加而效果加强,但施用量不可过高,当施用量为900 kg/hm~2时效果最佳,对根结线虫的防效为85.6%,对杂草的防除率为38.2%,单果重增加27.6%,可溶性固形物含量提高1.5个百分点,维生素C含量提高20.1%,每公顷产量增加18.9%。 In this paper, the strawberry varieties ’Red Cheeks’, which are the main cultivars in Nantong, Jiangsu Province, were used as materials to study the effects of different lime nitrogen rates on greenhouse strawberry cultivation. The results showed that compared with the application of urea, lime nitrogen had obvious effect on controlling root-knot nematode, inhibiting the growth of weeds and improving fruit quality and yield, and the effect was stronger with the increase of application rate, but the application rate should not be too high. The best effect was 900 kg / hm ~ 2. The control effect on root - knot nematode was 85.6%, the weed control rate was 38.2%, the weight of single fruit increased by 27.6%, the soluble solid content increased by 1.5% Vitamin C content increased by 20.1% and yield per hectare increased by 18.9%.
