摘　　要：通过钵盘育苗确定适宜的播种密度和插秧穴距。大田栽培条件下,以绥粳18为材料,设置3个播种密度和2个插秧穴距,研究播种密度和插秧穴距对绥粳18产量和品质的影响。相同播种密度下株高、穗数表现B2>B1,随着插秧穴距的减小呈现增加趋势;相同播种密度下结实率呈现B1>B2;理论产量表现B2>B1。在A1、A2播种密度下(1~3粒/穴、4~5粒/穴)精米率和整精米率表现B2>B1,相同播种密度下垩白粒率和垩百度表现B1<B2,随着插秧穴距的增大外观品质越好;蛋白质含量在插秧穴距(14.1 cm)下随着播种密度的增加而降低;播种密度为6~8粒/穴、穴距14.2 cm时提高食味值更显著。理论产量以A3B2(6~8粒/穴、穴距13.2 cm)处理最高为10994.9 kg/hm^(2),较A3B1(6~8粒/穴、穴距14.1 cm)处理提高了6.49%;食味值以A2B1(4~5粒/穴、穴距14.1 cm)处理最高为77.95分,较A2B2(4~5粒/穴、穴距13.2 cm)处理提高了5.01%。Determine the appropriate seeding density and planting hole spacing through pot-plate seedling raising.Under the condition of field cultivation,using Suigeng-18 as material,3 seeding densities and 2 transplanting hole spacing were set to study the effects of seeding densities and transplanting hole spacing on the yield and quality of Suigeng-18.The plant height and panicle number at the same seeding density showed B2>B1,and showed an increasing trend with the decrease of the distance between transplanting holes;the seed setting rate at the same seeding density showed B1>B2;the theoretical yield showed B2>B1.Under the seeding densities of A1 and A2(1~3 grains/hole,4-5 grains/hole),the milled rice rate and the whole milled rice rate showed B2>B1,and the chalky grain rate and chalky Baidu under the same seeding density showed B1<B2,with The larger the distance between the transplanting points,the better the appearance quality;The protein content decreased with the increase of seeding density under the distance between transplanting holes(14.1 cm);When the seeding density was(6-8 grains/hole)and the distance holes was(14.2 cm),the food taste value was more significantly improved.The theoretical yield of A3B2(6~8 grains/hole,hole distance 13.2 cm)was the highest at 10994.9 kg/hm^(2),which was 6.49%higher than that of A3B1(6~8 grains/hole,hole distance 14.1 cm);the taste value was A2B1(4~5 grains/hole,hole distance 14.1 cm)treatment had the highest score of 77.95 points,which was 5.01%higher than A2B2(4~5 grains/hole,hole distance 13.2 cm)treatment.
