The invention discloses a novel method for manual transplanting matched with seedling raising in sludge through soft porous trays for rice. The method comprises the following steps of 1, selection ofa seedling raising field, wherein the rice field which has convenient drainage, irrigation and transportation conditions and high fertility and contains few weeds is selected; 2, preparation of the seedling raising field, wherein the seedling raising field is subjected to early ploughing and early retting first, rice straw and weeds are removed thoroughly, and the seedling raising field is soakedin water; 3, preparation of seeds and materials, wherein the seeds and materials comprise hybrid rice seeds, conventional rice seeds, disposal porous trays with 353 holes or disposable porous trays with 434 holes, bamboo brooms, square sensing knifes, bailers, fishing line pulling ropes, bamboo poles with the length of 2 m, arched shed bamboo pieces with the length of 2.2 m and cover film; 4, seedtreatment, wherein seeds are soaked two days before seedling raising, and germination acceleration is started one day before seedling raising; 5, a series of seeding work, wherein the work comprisesthe steps of arranging the trays, filling the trays with mud, conducting flattening through sweeping, performing seeding, inserting rice seedlings, inserting the bamboo pieces, using the cover film for covering and arranging ditches; 6, rice field management; 7, manual transplanting of the seedlings. The method has the advantages of being simple in operation, low in requirements for instruments, equipment, technical conditions and the like and convenient to apply.
