[Cray­fish-Rice Dou­ble Crop­ping]

Place: Zhaonao Vil­lage, Xiongkou Town, Qian­jiang City High­lights: The 64-year-old farmer Ma Yulin sold 50 kilo­grams of cray­fish he gath­ered to a reg­u­lar cus­tomer and re­ceived one thou­sand yuan in ex­change. He counted the cash twice and then slid it in his pocket.

As the peak sea­son looms, Ma Yulin is busy gath­er­ing and sell­ing cray­fish. At the peak, he can earn 30 thou­sand yuan a day, which has made him an en­vi­ably rich man. In fact, be­fore 2014, he was only an or­di­nary farmer who earned less than 10 thou­sand yuan a year. He has ben­e­fit­ted tremen­dously from the new cray­fish-rice dou­ble crop­ping model pro­moted in Qian­jiang City.

In 2014, in or­der to de­velop an econ­omy for the vil­lagers, the lead­ers of Zhaonao vil­lage co­op­er­ated with

Huashan Com­pany and pro­moted the cray­fish-rice dou­ble crop­ping model.

This model is the ex­clu­sive in­ven­tion of Qian­jiang City. The farm­ers dig a cir­cu­lar gut­ter with a width of four me­ters and the depth of 1.5 me­ters along the rand of the rice field. When it is time for rice trans­plant­ing, the baby cray­fish are put into the gut­ter. When the seedlings are stronger, the cray­fish are led back to the rice field. In this way, the cray­fish can be gath­ered in May and Septem­ber, form­ing the so-called

“One rice and two cray­fish” yield.

The cray­fish- rice con­tin­u­ous crop­ping model can pro­duce about

200 kilo­grams of cray­fish and can earn about 5000 yuan per acre. This method has reached the goal of el­e­vat­ing both the pro­duc­tion and qual­ity of cray­fish.

“At the be­gin­ning, many farm­ers were not fa­mil­iar with this model and re­fused to con­tract. The cadres and some brave farm­ers took 30 ponds.” The “ponds” men­tioned by the sec­re­tary of the vil­lage Zhao Changhong re­fer to rice fields where rice and cray­fish grow to­gether. “One pond is about 40 acres. In the first year, the av­er­age profit of a pond was about 50 thou­sand yuan, which greatly aroused the in­ter­ests of the farm­ers. Now there are more than 160 ponds and each can earn about 150-200 thou­sand yuan per year.”

Ac­cord­ing to the sta­tis­tics, by April of 2017, the area used for cray­fish breed­ing in Qian­jiang City reached half a mil­lion acres. Nine breed­ing bases with more than 10 thou­sand acres and 50 breed­ing bases of one thou­sand acres have been built. The ag­gre­gate value of the cray­fish in­dus­try chain has reached 18 bil­lion yuan. There are two key agri­cul­tural en­ter­prises in­volved: Laker Sea Food and Huashan Sea Food. In the last year, the vol­ume of for­eign ex­change earned by ex­ports in Qian­jiang City has ac­counted for 60% of the pro­vin­cial to­tal and 40% of the national to­tal of cray­fish. Qian­jiang City has ranked first among all ci­ties for nine con­sec­u­tive years and is the global leader in the cray­fish in­dus­try.

While guar­an­tee­ing high pro­duc­tion, the cray­fish in Qian­jiang City also main­tains high qual­ity.

“We should pro­tect the brand of Qian­jiang Cray­fish, just as tak­ing care of our eyes.” Ac­cord­ing to Lu Zhonghu, the chef engi­neer of the Qian­jiang Bureau of Aquatic Prod­ucts, in the pro­duc­tion process, fre­quency- emit­ting pestkilling lamps are used in­stead of pes­ti­cides. Mi­cro­bials and in­sects that grow on the rice work as the food for the cray­fish and the exc­reta pro­duced by the cray­fish of­fers high-qual­ity fer­til­izer for the rice. The straws af­ter the harvest cre­ate the nat­u­ral habi­tat for cray­fish and the rot­ten straws en­rich the soil’s fer­til­ity.

This state­ment can be proven by the amount of fer­til­izer that has been used in Zhaonao Vil­lage. In 2014, 210 tons of fer­til­izer were used. The fig­ure de­clined in the fol­low­ing years: 140 tons in 2015, and just 70 tons in 2016.

In this com­ple­men­tary bi­o­log­i­cal chain, the qual­ity of the cray­fish and rice are both el­e­vated and the rice is or­ganic rice that grows nat­u­rally. Only phys­i­cal or bi­o­log­i­cal means are used to pre­vent pests in the whole process, which re­duces the us­age of pes­ti­cides, fer­til­iz­ers, and wa­ter. It not only helps to main­tain the ecol­ogy and en­vi­ron­ment, but also guar­an­tees food se­cu­rity. This process ad­heres to the re­quire­ments of the new times: re­duc­ing, re­plac­ing, con­trol­ling, and com­pre­hen­sively us­ing all re­sources pos­si­ble.
