针对南方双季稻区早稻密植、晚稻稀植多元化种植特性,通过对南方双季稻区不同早稻品种(湘早籼45、嘉早312、两优9168)进行窄行距(24cm)和常规行距(30cm)机插秧的对比试验,研究了不同早稻品种宽窄行距机插秧对水稻的生育期和产量的影响。结果表明:对于早稻,窄行距(24cm)机插秧水稻具有生育期短的优点,且增产明显;而常规行距(30cm)机插秧水稻生育进程相对落后,产量较低。由此可见,利用窄行距插秧机合理密植,科学调整早稻亩穴数,保证稳产高产必须的基本苗数,可提高南方双季稻区粮食产量。
針對南方雙季稻區早稻密植、晚稻稀植多元化種植特性,通過對南方雙季稻區不同早稻品種(湘早秈45、嘉早312、兩優9168)進行窄行距(24cm)和常規行距(30cm)機插秧的對比試驗,研究瞭不同早稻品種寬窄行距機插秧對水稻的生育期和產量的影響。結果錶明:對于早稻,窄行距(24cm)機插秧水稻具有生育期短的優點,且增產明顯;而常規行距(30cm)機插秧水稻生育進程相對落後,產量較低。由此可見,利用窄行距插秧機閤理密植,科學調整早稻畝穴數,保證穩產高產必鬚的基本苗數,可提高南方雙季稻區糧食產量。

In Southern double cropping area ,The rice planting diversified patterns have been formed that Performance in early rice need close planting and late rice need sparse planting .This paper is comparison study of different early rice cul-tivars by narrow row spacing and conventional spacing transplanters ,in southern double cropping area .Comparative study on the effect of rice of growth period and yield under two conditions .The results show that the narrow row spacing (24cm) has the advantages of machine transplanting rice is the short growing period and obvious yield increasing ,While the conventional row spacing (30cm) characteristics of machine transplanting rice is the growth process is relatively back-ward and low yield .So narrow row spacing transplanter rational close planting and adjustment of rice Mu point number in scientific that ensure basic seedling number of high and stable yield .Ultimately improve the Southern double cropping area harvest rice grain yield .
