Comparing with early rice k uptake at seedling and maximum tillering stage in late rice was obviously higher , while k uptake at full heading and ripe stage was lower , so for potassium fertilization of early rice , we should pay attention to both early stage and middle stage 与早稻相比，晚稻在苗期和最大分蘖期明显较高，而齐穗期和成熟期吸钾较低，所以对早稻施钾来说，我们应注重早期和中期施用。
The yield per unit of the second pattern obviously declined , which was 487 . 4 kg / 667m2 , but the total value was greatly improved , the mean was 6965 . 0 yuan , and the net income was 5321 . 5 yuan . for this pattern one - season late rice was mainly planted 一粮一经的粮食单产显著下降，每667米2产量37例平均为487 . 4kg ，但总产值极显著提高，平均为6965 . 0元，净收入5321 . 5元;这种模式以种植一季晚稻为主。
As was proven by the experiment , the average harvest indexes were 0 . 62 for early rice and 0 . 61 for late rice respectively at shaoxing , while 0 . 57 and 0 . 55 for fuyang , this means that a similar rice yield at fuyang would require larger amount of total dry matter production than at shaoxing 试验证明，绍兴早稻和晚稻的平均收获指数分别为0 . 62和0 . 61 ，富阳的分别为0 . 57和0 . 55 ，这意味着同样的水稻产量在富阳需要比在绍兴更大数量的干物质生产。
So in order to get good response for hybrid early rice , potassium fertilizer should be applied at early stage , attention should also be paid to middle stage ; for hybrid late rice , k supply in seedling stage and tillering stage should be paid more attention , at middle - late stage certain amount of k should be supplied according to k nutrition 因此为了使杂交早稻有更好的反应，钾肥应在早期施用，中期也应重视钾；对杂交晚稻来说，在苗期和分蘖期应格外注意施钾，在中后期也应根据钾营养状况施用一定量钾。
Three methods , namely , community species composition similarity analysis , community composition similarity analysis , and community characteristic similarity analysis , were employed to study the similarity of insect pest - natural enemy communities of three rice types ( early rice , middle - season rice and late rice ) and their three development stages ( tilling stage , boot stage and milk stage ) in the yangtze - huaihe region of anhui province 摘要采用群落种组成相似性分析、群落组成相似性分析和群落特征相似性分析3种方法，研究了安徽江淮地区早稻、中稻、晚稻3种稻型及分蘖、孕穗、乳熟3个生育期害虫天敌群落的相似性。
As has been demonstrated by the data in tables 1 , 3 , 5 and 6 , the total average yields of two rice crops have reached 15 , 482 kg / ha ( 7 , 937 kg / ha on early rice and 7 , 545 kg / ha on late rice ) at shaoxing and 14 , 876 kg / ha ( 5 , 943 and 8 , 942 kg / ha on early and late rice respectively at fuyang , the yields have touched or almost close to the yield target required for triple cropping of - " project of 15 ton grain yield per hectare " which is carrying out in the province 表1 、 3 、 5 、 6中数据显示，两季水稻总平均产量在绍兴已达到15 , 482公斤/公顷（早稻7939 ，晚稻7545公斤/公顷） ，在富阳已达到14 , 876公斤/公顷（早稻5943 ，晚稻8942公斤/公顷） ，该产量已达到或接近浙江省推行的吨粮田计划中三季稻的产量目标。
