4000 Xiaokang warehouses have been built in Lijin County, Shandong Province.

Recently, Zhang Hongbin, a farmer from Dongsan Village, Mingji Township, Lijin County, Shandong Province, pointed to a well-off warehouse and said: "storing grain in a well-off warehouse is clean, hygienic and practical." The Baocun Group of the County Grain Bureau has provided free well-off warehouses for 103 farmers in Dongsancun, making it convenient for the masses to store grain. It is understood that since last year, the county has promoted 4000 small health warehouses, which can reduce grain losses by 200 tons per year compared with traditional grain storage methods.

The county implements the scientific grain storage project for farmers and encourages farmers to store their own grain rations so as to store grain among the people. In the past, due to poor grain storage conditions and relatively casual storage methods, insect erosion, rat bites and mildew were very common, with an annual grain loss rate of 6% and 8%. Farmers' scientific grain storage demonstration warehouse can effectively solve this series of problems. The demonstration warehouse, also known as a well-off warehouse, compared with the traditional grain storage method in rural areas, has the characteristics of simple installation, wide use, no pest and rodent damage, moistureproof and heat insulation, long service life, economy and practicality, etc., and can ensure the safety of scattered grain storage from household to house. at the same time, it has the advantages of quality and fresh keeping, reducing loss, economic beauty and so on. It not only solves the problem of great loss of rat bite and erosion caused by farmers storing grain in the past, but also makes it simple, convenient, time-saving and labor-saving for farmers to store grain. The popularization and use of Xiaokang has important practical significance for reducing farmers' grain storage losses and improving farmers' grain storage environment.
