Xiaobu learned from the Municipal Bureau of Agriculture and Rural Affairs
Aiming until 2025
The city's facility vegetable area reached 5,000 acres
The self-sufficiency rate of vegetable production exceeded 50%
Make every effort to ensure the production and supply of the island's "vegetable basket".
How can this be achieved?

Yesterday morning, at the site of the city's island modern facility agriculture and comprehensive planting and breeding site, the saline-alkali land "rice and fishery co-cultivation" experimental field attracted the attention of the participants.
In May last year, the park used 60 acres of farmland to take the lead in the city to pilot the creation of "rice and fishery co-cultivation" experimental field, using two modes of rice crab and rice shrimp symbiosis, and according to the rice planting time to reasonably arrange the stocking time of blue crabs and crayfish, control the density of blue crabs to 120 per mu, and the density of crayfish to 8 kg per mu. As of now, the survival rate is over 70%.
Li Jingqi, person in charge of Daishan Island Modern Agricultural Park: Our advantage is that we can harvest in May and June on saline-alkali land. It is estimated that blue crabs are about 15 kilograms per mu, and crayfish are about 50 kilograms per mu. Blue crabs and crayfish can also effectively loosen the soil, prey on pests and plankton, etc., and the amount of chemical fertilizers and pesticides has also been reduced by more than 30%.
Compared with rice monoculture under the same conditions
The output value of rice crab per mu can reach 5,000 yuan
257% increase in revenue
The output value of rice and shrimp per mu can reach 4,000 yuan
185% increase in revenue
Exploit the potential of existing arable land
Achieve a "win-win" situation between rural ecology and economic benefits
Recently
Our city actively explores the "rice +" model
Putuo Dengbu passed the implementation
"Golden melon + selenium-rich rice" crop rotation
Last year, the yield of golden melon per mu increased to 1,250 kilograms
The yield of rice per mu increased to 330 kg
10% increase in land yield
It is understood that this year, the city will continue to sort out the regional plots that can be developed for comprehensive planting and breeding such as "rice + fishing", "rice + melon" and "rice + vegetables", and formulate a "map" of development potential and development plans. It is planned to expand the area of comprehensive planting and breeding by more than 50 acres in Dinghai and Putuo through the pilot of crop rotation and symbiosis.
In addition, this year the city will also:
The new and upgraded facilities cover an area of 1,000 acres
Start Dengbu, Zhujiajian, Qushan, etc
Construction of "vegetable factories" on 5 islands
1,000 acres of new guaranteed vegetable bases
6 high-quality vegetable intensive breeding and seedling supply bases have been built
Build a vegetable industrialization consortium
7 companies have implemented order agricultural production and marketing cooperation
Efforts should be made to improve the level of modernization of facility agriculture
Speed up the development of new quality productive forces in agriculture
