Sharing High-Yield Planting Experience for Autumn Potatoes
Mr. Zhang Chaohu from Jinghe Subdistrict Office, Tengzhou, Shandong, achieved a high yield of 1500 kg/mu with his autumn potatoes this year. His experience is as follows. 1. Seed potatoes: This spring he used virus-free Dutch No. 5 potatoes shipped from Northeast China to plant a spring potato crop, harvested in early June. From these he selected small tubers grown from vigorous plants with no symptoms of viral infection, and used whole tubers as seed. To prevent disease infection, the seed potatoes were not cut into pieces, and mechanical damage was avoided as much as possible. To promote rapid sprouting of the seed potatoes, 12 days before sowing, they were sprouted using a gibberellin glycerol solution

How to grow direct-seeded rice? Experience shared by Jingtoushan Farm
Our farm has nearly 700 hectares of paddy fields. We began direct seeding of rice in 1987 and fully promoted it starting in 1999, with a 100% success rate. The key points of this direct seeding technique are mastering the following three critical stages. 1. Land preparation stage. Plow the paddy field, break up the soil, and irrigate; either machine leveling or oxen leveling will do. Then use a leveling bar to smooth the field flat. Use a homemade ditching board to open the furrows. The ditching board is 2 m long, 45 cm wide, and 3 cm thick. On the wooden board, nail 2 handles on each side, each 30 cm long, with a width of 1.6 m between the handles, for attaching ox harness ropes
