摘要
在旱地覆膜栽培条件下，临丰116具有良好的苗型结构和产量结构，抗旱节水优势强，叶片功能期长，耐高温，抗干热风，根穗比值大，抗倒伏，不早衰，穗大，粒重，产量高。该品种是旱地覆膜栽培较理想的配套品种。同时探讨了覆膜栽培配套品种的育种目标。
The biological characters for Linfeng 116 were studied unde three cultural practices. Theresults showed, under mulching cultivation in rainfed areas, that Linfeng 116 was provided with the goodconstruction of seedling and yield, and strong superiority of drought resistance and saving water. lt alsokeeps the long function of leaves, thermostability and hot air to resistance, which result in droughtresistance for increasing production. The another character of the variety is possessed of the high ratios ofroots and spikes, lodging resistance, not early ageing and big spikes and weighty grains. Linfeng 116 is aoptimum necessary variety for mulching cultivation. The breeding Objective of the variety with adaptivemulching cultivation were discussed.
