Analysis of Grouting Laws of New Variety Xinmai 29 with Super-high Yield
摘要
Abstract
[Objective]To analyze the grouting laws of new variety Xinmai 29 with super-high yield.[Method]With Xinmai 29 as the test materials, we researched the dynamic changes of seed formation, grouting laws,the dynamic changes of leaf composition,and dry matter ac-cumulation.[Result]Under the super-high yield condition, Xinmai 29 had a long period of grain filling, and the weight of grain in filling stage increased fast with an average of 2.3 g of 1 000-grains per day;the leaves of Xinmai 29 stuck out and had good light transmittance,and the top-three leaves had long functional period.Under the super-high yield condition,the index of the leaf area came to 7.75,the index of the top-three leaf was 5.06 and the index of the flag leaf was 1.72;the dry matter weight of Xinmai 29 was mainly from the photo-synthate after flowering.[Conclusion]Xinmai 29 was most stable under the yield level of 7 200-19 115 kg/hm2.The optimal mode of yield structure was effective spikes more than 6115 000 spikes/hm2,32.3 grains per spike and 1 000-grain weight around 50.5 g.关键词
