No longer worrying about droughts and floods? This seemingly whimsical idea has now been turned into reality by a high-tech product called "bio absorbent". This product has now been industrialized at Runtong Biological Super Absorbent Co., Ltd. in our city.

Biological water absorbing agent, scientific name "water absorbing resin", is a high molecular weight polymer. This product is in the form of powdered particles, each of which can absorb, retain, and release water with an "appetite" hundreds or even thousands of times its own weight. During spring sowing, simply arrange it at a ratio of 1:1500&By adding a ratio of 2000 to water and mixing it with seeds or strips planted in farmland, "micro reservoirs" can be formed in the soil - releasing water during droughts and adsorbing water during floods, making it possible for farmland to maintain harvests during droughts and floods.
In September 2003, Professor Zhang Liansheng, the head of the polymer research base of Heilongjiang University, invented the technology of "foam system polymerization" to produce biological absorbent, which was successfully introduced by Runtong Company. The company invested 10 million yuan to build its first 3000 ton production line, which quickly transformed this major scientific research achievement into a product. The news spread quickly, and the provincial agricultural science and technology promotion station has set up 7 demonstration sites for promotion and application in the province this spring, using the product in rice seedling raising, fruit tree, edible mushroom, potato and other economic crop production. According to the relevant person in charge of the Municipal Development and Reform Commission, the production of this product has been included in the key project of high-tech industrialization in our city, and the second phase of the project with an annual output of 10000 tons of products is under construction.
According to experts, the production technology of this biological water absorbent is a world first and has obtained invention patents in 12 EU countries. The product not only ensures stable and increased agricultural production and farmers' income, but also has broad promotion space due to its low cost of use. According to calculations, the product is applied at a rate of 1 kilogram per mu of land, with a selling price of 20 yuan per kilogram. After application, it can increase the yield per mu by at least 10%—15%， Farmers can receive a minimum of 2 on the premise of ensuring their income during droughts and floods&Triple investment return.
