摘要:: 本试验选取龙垦201 为试验材料，以氮肥不同施入量和不同插秧密度两个因素为切入点，将不同施氮量6kg/亩、10kg/亩、14kg/亩，插秧规格30cm×12cm、30cm×10cm、每穴3、5、7 株等因子进行随机组合，共设18 个处理，通过对分蘖、产量及产量构成因子的测定，结果显示穴株数与单株分蘖数成反比，在一定范围内随着施氮量的增加，分蘖呈增加趋势，千粒重随着施氮量的增加而降低。处理14（氮肥施用量10kg/亩，插秧规格30cm×12cm，每穴5 株）产量最高，处理3 （氮肥施用量6kg/亩，

Abstract:: This test to select the dragon Ken 201 as test materials, with different nitrogen fertilizer applied into the different planting density and quantity of the two factors as the breakthrough point, different n application 6 kg/mu, 10 kg/mu, 14 kg/mu, planting specifications 30 cm * 30 cm * 12 cm, to 10 cm, 3, 5, 7 strains every hole factors such as random combination, a total of 18 processing, through the determination of tiller, yield and yield components, the results show that the cavity number is inversely proportional to the tiller number per plant, within a certain range with the increase of n application rate, the tillering increased, grain and decreased with the increase of n application rate. The yield was the highest at 14 (10kg/ mu n application rate, 30cm x 12cm seedling planting rate, 5 plants in each hole), while the yield was the lowest at 3 (6kg/ mu n application rate, 30cm x 10cm transplanting rate, 7 plants in each hole).
