When the winding shaft 5 is wound to a certain radius, a signal is sent out, the cutting mechanism 10 is controlled to cut off the seed film coated with the film, and the new winding shaft 5 is replaced by manual assistance.

Usually, agricultural paper is used as a seed bottom film 100, a forming and gluing mechanism 2 is used for extruding a holding tank 201 capable of holding seeds and required slow-release fertilizers, glue containing insecticide and disease-killing pesticides is coated in the tank, then, a seeding and fertilizing mechanism 3 is used for placing a proper amount of seeds which are subjected to early treatment such as seed coating and the like in the holding tank 201 according to a reasonable interval, short-term slow-release fertilizer (tillering fertilizer), medium-term slow-release fertilizer (spike-pumping fertilizer) and long-term slow-release fertilizer (grouting fertilizer) are respectively placed at positions 30-50 mm away from the seeds, after subsequent leak detection and reseeding, a thin paper protective film which is easy to be changed when meeting water is covered on the holding tank 201, namely a seed upper film 200 is covered, the seed upper film 200 is quickly fixed by a heat-sealing film covering mechanism 4, then, a low-temperature air drying mechanism 8 with the temperature lower than 60 ℃ is used for air-drying the glue for bonding the seeds and the slow-release fertilizer, a winding shaft 5 is used for winding the seed film into a roll for standby, the process is carried out in a factory by using special equipment. In the cultivation season, the planting work is completed by manually or mechanically paving a seed film on the cultivated land, links such as seedling raising, seedling transplanting, weeding, fertilizing and the like are omitted, the labor intensity is greatly reduced, and the production efficiency is improved. As shown in fig. 14, the seed basement membrane 100 is made of agricultural paper with certain strength and begins to rot about 60 days (mainly preventing the growth of weeds and fertilizer loss), and about 60 days is the middle stage of rice tillering, at this time, the weeds can not compete with seedlings after emerging, and the downward development of rice root systems and the absorption of nutrients in the soil can not be influenced. The slow release fertilizer is placed at a position 30-50 mm away from the seeds according to the slow release time from short to long, so that the fertilizer and the seeds are prevented from burning roots too close, and the slow release fertilizer is determined according to the development condition of root groups. The slow release fertilizer is made into an approximate circle with the diameter less than 4mm, and each grain contains an effective fertilizer ingredient with a basic component, so that accurate quantitative fertilization (which can be realized by controlling the grain number of the fertilizer) can be realized.
