The specific technical points are as follows: the pan soil is ready to choose soil fertile, no stubble, gravel, weeds, loam without pollution to seedlings, PH 4.5-5.5. If there is no such acidic soil, sulfuric acid and nitro humic acid can be used to adjust acid. In order to prevent the occurrence of seedling diseases such as blight, 50-60 grams of dimethazone were applied per cubic meter of pan soil. Fertilize the pan soil, adding pure nitrogen, pure phosphorus,

Ten regiments of the first division of agriculture pioneered a new dry farming technique of drip irrigation under plastic film for rice.
In 2010, the first Agricultural Division and the Ten Regiment of the production and Construction Corps used new science and technology to transform traditional agriculture. According to the serious shortage of water resources and the disadvantage of being located in the lower reaches of the water supply unit of the first division, the independently developed new rice drip irrigation and dry sowing machine was used in rice production, which has been vigorously promoted by Alar, a division. According to Kong Jun, deputy commander in charge of agriculture in the first division, this cultivation model not only ensures that rice planting saves not only labor, but also water resources and farmland costs, and is conducive to increasing production and efficiency of rice.
