摘　　要：汕优６３制种采用母本点直配套技术，亩产量可超３００ｋｇ，达到了增产增收节省成本的目的．文中 介绍了其主要技术经验．In 1991, it was found that the application of the direct hill -seeding culture of the seed parent on the seed production of Shanyou 63 increased the seed yields and saved investment. The key points of this new technique to get a seed yield of more than 4.5t/ha in Shanyou 63 are： ① Well-arranging the seeding time of the parents to ensure heading and flowering under favourable climatic conditions ; ② Strengthening the culture of the pollen parent to ensure sufficient pollen load; ③High-quality seeding of the the seed parent with 4-5 germinated seeds per hill and the bill-eding spacing of about 12. 0cm× 13. 3cm; ④Wellmanaging the water and fertilizer to establish a high-yielding population structure; ⑤ Timely-controlling the diseases and insect pests.
