All things are born, and spring plowing is busy
Walking into the sweet potato base of Guangdong Xiangjun Agricultural Technology Co., Ltd., Yancang Village Committee, Poxin Town, Dianbai District, the sweet potato seedlings are green, the spacious field road, the drone is fertilizing and watering...... "The temperature is warm, fertilize first, and then water again." Fertilization and watering, we use drones, not only to save fertilizer, but also to spread evenly, the absorption of potato seedlings is more sufficient, and it is expected that the potato seedlings will be cut in half a month. Ke Haiqing, the person in charge of the base, said.
Sweet potatoes are also called "sweet potatoes". According to the data of the Dianbai District Agriculture and Rural Bureau, in 2023, the planting area of Dianbai sweet potato will be 62,000 mu, with an output of more than 110,000 tons and a yield of 1,831 kg/mu, which is higher than the provincial average. Last year, at the launching ceremony of the 22nd Guangdong Seed Industry Conference and the "Millions of Projects" Seed Industry Trading Center held in Kemulong, Guangzhou, the Guangdong Provincial Department of Agriculture and Rural Affairs announced the list of the first batch of 18 key counties for sweet potato production improvement actions, and Dianbai District was among them, receiving 4.8 million yuan of special fund support.
"Sweet potato for half a year". In many places, sweet potato is the second largest food crop after rice, and it is the "ballast stone" for the people's rice bowl. Under the background of increasingly limited cultivated land, especially cultivated paddy fields, sweet potato is attracting more and more attention due to its high nutritional value, drought tolerance and strong adaptability. Dianbai District seized the opportunity to seize the opportunity of the implementation of the project in the key counties of the sweet potato yield improvement action, relying on the unique light and heat conditions, and took the development of sweet potato planting as an important starting point to stabilize the grain area and increase the grain output, and continuously enhance the ability to guarantee food security.
In recent years, Dianbai has focused on the implementation of the "Millions and Millions Project", consolidated the foundation of food security in an all-round way, built a diversified food supply system, further promoted the action of improving sweet potato production, deployed and created a number of key towns for sweet potato production improvement, and strived to promote the mechanization, branding and marketization of the potato industry. Sweet potato production is expected to increase by more than 5% this year.
01 The output is increased, and the seed core is strong first
At present, the local sweet potato varieties mainly include Pushu 32 (watermelon red), Marsali, ginseng potato, durian honey potato, Diandian red and Guangshu series, etc., with a good seed rate of 85%. However, as a vegetatively propagated crop, once sweet potato is infected with viral disease, the virus will continue to multiply, accumulate and pass on from generation to generation in the sweet potato, making the disease aggravate from generation to generation, so viral disease is an important reason for the degradation of sweet potato seed, yield reduction and quality deterioration. At present, nearly eighty percent of farmers' sweet potato seedlings are kept for themselves or exchanged between farmers, which is easy to cause degradation of sweet potato varieties and affect yield and quality.
In order to comprehensively promote the planting of sweet potato detoxification seedlings in farmers, Dianbai District has accelerated the construction of sweet potato detoxification and healthy seedling breeding bases. Guangdong Agricultural Core Agricultural Technology Co., Ltd., located in Lingwei Village Committee, Xiaoliang Town, is a modern agricultural technology company focusing on the breeding, promotion and planting of healthy seedlings of sweet potato detoxification, the company has a local circulation land area of more than 300 acres, and has established more than 200 square meters of sweet potato tissue culture room, purchased relevant experimental instruments and tissue culture equipment, and carried out sweet potato seedling breeding and testing. According to Luo Jiaxi, the boss of the company, "we will plan to build a 40-acre sweet potato net room greenhouse to further expand the breeding capacity of sweet potato seedlings in the base and provide farmers with high-quality detoxified and healthy sweet potato seedlings." ”
02Create a demonstration area for high yield and high efficiency of sweet potato
With the support of the green and efficient cultivation technology system, the creation of 5,000 acres of sweet potato high-yield and high-efficiency demonstration pieces is an important part of the implementation of the sweet potato yield improvement action in Dianbai District. The perennial planting area of sweet potato in Dianbai District is more than 60,000 mu, and from the perspective of planting season, spring, summer and autumn are planted in all seasons, among which the planting area of autumn potatoes is the largest. In order to further promote the expansion of sweet potato planting, Dianbai District vigorously promotes the intercropping and crop rotation between sweet potato and different crops, actively develops the "rice-rice-potato" water-drought rotation model, and makes full use of winter fallow fields, seasonal paddy shortage fields, dry (sloping) land, and recultivated abandoned land to increase the planting area of sweet potato. Through the creation of demonstration films, we will actively promote the mechanization technology of sweet potato farming, planting and harvesting, as well as the green pest prevention and control technology model, reduce labor input, promote the standardized production of sweet potato, and drive the large-scale yield improvement and balanced increase of sweet potato.
03 Not only "grow" well, but also "sell" well
To do a good job in the sweet potato industry, we must not only "plant" well, but also "sell well" and "speak" well. Xie Yuanxin, chairman of the grass bran breeding professional cooperative of Geshan Village Committee, Guanzhu Town, Dianbai District, is a young man, but he is a senior "old man" in the field of e-commerce sales, who has been engaged in sweet potato e-commerce for 5 years, and has his own brand trademarks "Wancaozhai" and "Tiantoucang". He sold no less than 2 million catties of sweet potatoes on e-commerce platforms such as Douyin, Kuaishou, Taobao, Pinduoduo, and Alibaba. He did not have enough sweet potatoes to sell in his own base, so he signed sweet potato purchase and sales agreements with other farmers, provided sweet potato seedlings free of charge, and bought back the sweet potatoes grown by the farmers at a price not lower than the market price.
04 Tell the story of "Xiadong Sweet Potato".
In Xiadong Town, Dianbai District, the legend of sweet potatoes is well-known. There used to be a "Sweet Potato Forest Temple" here, which is said to have been built by the local people to commemorate Lin Huailan, the first person to introduce sweet potatoes. In order to tell the story of "Xiadong Sweet Potato", dig deep into the cultural value of Xiadong sweet potato, and polish the historical signboard of Xiadong "China's first township of sweet potatoes", Dianbai District accelerated the promotion of Xiadong Sweet Potato National Geographical Indication Identification, organized experts to demonstrate and formulate Xiadong Sweet Potato Group Standards, and actively planned to hold sweet potato industry promotion activities, build a high-quality brand of Dianbai Sweet Potato, and promote Dianbai Sweet Potato to "enter the Bay Area, go to the whole country, and go abroad".
