水稻品种混合种植方式及增产效果的研究

STUDY ON MIXING PLANTING AND THEIR YIELD OF RICE VARIETIES

摘要:

本文通过不同形态特征和生理特性的中熟及中晚熟水稻品种混合种植的试验, 提出了高秆大穗型品种与中矮秆多蘖、多穗型品种混播、混插; 多品种以不同比例混插; 多品种1: 1混播混插等最优混种、混插方式; 并得出了不同品种混种、混插方式的增产效果与增产比例; 明确了混种、混插群体的抗病、抗倒伏能力。

Abstract:

This article reports, accorcing to the different morphological characters and physilogical traits, the mixing ways and methods of medium and middle late mature varieties. And it gives the mixing ways of the long-stalked and larger ear varletes with medium-lower and multiple ear varieties. It also gives the best mixing planting and transplanting ways in different proportion and 1:1 of mamy varietes. The yield increasing results and proportion of each mixing way have been achieved. The ablities of disease and falling resistance of mixing variefis have been evaluated.
