"You see that the quality of the rice we produce is very good, very popular, 1 yuan per catty is more expensive than the average rice in the same area, and the cooperative can save 880,000 yuan a year! Recently, the "Jinhe Yuan" brand rice produced by Jiangsu Hai'an Shangpin Grain Planting Professional Cooperative won the special prize of the 8th "Huaxi Village" Cup "Jiangsu Good Rice" tasting and promotion meeting, and Han Baofu, the head of the cooperative, held his own rice and blossomed.
Han Baofu introduced that high-quality rice benefited from the pilot project of green planting and circular agriculture. Since 2021, the cooperative has participated in the pilot of green planting and breeding circular agriculture, and until 2023, the cooperative has used the integrated technology of biogas slurry water and fertilizer in more than 900 acres of rice fields, and applied biogas slurry 25 tons. "Last year's autumn harvest was calculated, and the cooperative saved a total of 13 urea5 tons, a good harvest of 642 kg per mu was achieved. Han Baofu said. In Hai'an, a total of 56 family farms have applied biogas slurry to rice cultivation in 2023, benefiting 350,000 acres.
Hai'an City is a major animal husbandry city in Jiangsu Province, known as "millions of roosters in the south of the Yangtze River" and "the hometown of poultry eggs in China", with a perennial livestock and poultry manure production of more than 1 million tons. If livestock and poultry manure is not treated well, it is pollution and trouble, and it is an important resource of organic fertilizer if it is treated.
In 2021, Hai'an City applied for the pilot project of green planting and breeding circular agriculture, and since the implementation of the pilot, Hai'an has made great efforts in "farmer accumulation" and "socialized services". In order to promote the utilization of manure to the field, Hai'an City has focused on cultivating 15 socialized service organizations, and promoted the signing of agreements between socialized service organizations and farm households, forming a unified collection, centralized fermentation, directional distribution, and mechanically applied manure returning to the field, and exploring the three technical modes of "biogas slurry fertilizer + formula fertilizer", "manure + formula fertilizer" and "compost manure + formula fertilizer", so as to realize the return of livestock and poultry manure to the field and make full use of it.
Unlike solid fertilizers, biogas slurry fertilizers are seasonally used and have a short service time, which outstrips supply when needed, and has nowhere to go when not in use. To this end, Hai'an City has successively built biogas slurry tanks, septic tanks, and transfer tanks 2More than 60,000, a total of 820,000 cubic meters. According to the calculation of 1 million pig equivalent pig equivalent of livestock and poultry manure production in the city in 2023, the manure storage facility occupied by a unit of pig equivalent will reach 073 cubic meters, to meet the city's fertilizer off-season manure storage needs.
The pilot project of green planting and breeding circular agriculture came in time and brought a lot of benefits to the people! Zhong Chongping, an agricultural technician from Hai'an Cultivated Land Quality Protection Station, has a deep experience. Since the implementation of the pilot project for three years, the technical staff of Hai'an Agriculture and Rural Bureau have gone deep into the field to provide on-site guidance, organize training and observation more than 20 times, serve more than 2,000 farmers and service subjects, and return more than 300,000 mu of manure to the field in the city's demonstration area, driving more than 900,000 mu of surrounding farmland to apply manure, saving more than 4,500 tons of chemical fertilizer (converted to pure), saving more than 30 million yuan in cost saving and increasing income.
