分段收割与直收对水稻产量的影响

Effect of Partial Harvest and Conventional Harvest on Yield of Rice

为了探寻不同收获时期与不同收获方式对水稻产量的影响,采用不同方式收获,用称重法测量出水稻茎秆与籽粒的重量,从而分析出营养成分的走向。试验结果表明:割晒与直收在不同时间上收获对产量影响情况处理2>处理3>处理1。通过本次试验分析出割晒脱粒效果较好,抽穗后63 d左右为最佳的收割时期。

Using the weight method to measure the weight of stalk and grain and analyse the trend of foodstuff in order to explore the effect of harvest dates and method on yield of rice.The results indicated that harvest at different time between cutting and drying and direct had effect on yield were treatment 2treatment 3treatment 1.From the test it analysed that cutting and drying can achieve better effect on threshing and the best harvest time were 63th day after heading.
