不同穗型不同种植方式对水稻光能利用的影响

水稻直立穗品种育成后,对不同穗型品种的受光条件的优劣以及在何种种植方式下能提高水稻对光能的利用的研究已引起重视。本文从光照条件角度研究水稻不同穗型品种在不同种植行向以及在相同种植密度下不同株行距接受光照的差异进行了初步研究,结果表明:直立穗品种、弯曲穗品种都适宜东西行种植;在相同的种植密度情况适当增加行距有利于水稻充分利用光能,从而有利于水稻高产。

Effect of Different Rice Leaf on Absorbing Uprightness Light in Different Planting Ways

After the erect spike type rice was bred,the research into possibility improving light utilization had been put on agenda. This paper primarily studied the difference in absorbing light of different plant type of rice both in different planting direction and different row spacing in the same planting density at random blocks design. The experimental results showed that both the erect panicle rice and the bend panicle rice making use of the sunshine are better in W-E row than in N-S row.And in the same plant density, increasing the row spacing was beneficial to improving the yield of rice.
