On August 30th, in the “experimental field” of Huinong Vegetable Professional Cooperative in Lianghekou Town, Chaotian District, Guangyuan City, production experts organized by the Sichuan Horticultural Crop Technology Promotion Station were busy conducting field production testing and acceptance of the “green, light, and high yield cultivation technology for high mountain summer chili peppers”. They randomly selected three sampling points, counted the number of fruits per plant and young fruits, and measured the spacing between rows to calculate planting density.
It is understood that in order to improve the utilization rate of land, light and heat resources, as well as the comprehensive benefits per unit area in high mountain areas, since 2020, the Horticultural Research Institute and Plant Protection Research Institute of Sichuan Academy of Agricultural Sciences have innovatively formed the “Early Spring Cabbage+Summer Pepper Annual Efficient Planting Model” suitable for high mountain areas in Northeast Sichuan through research, experimentation, and demonstration, And in 2023, demonstration planting was conducted at the Huinong Vegetable Professional Cooperative in Lianghekou Town, located in the Gaoshan Vegetable Technology Innovation and Achievement Demonstration Base in Chaotian District.
The ‘Early Spring Cabbage+Summer Chili Pepper Annual Efficient Planting Model’ selects early maturing beef heart cabbage varieties and early middle maturing chili pepper varieties, optimizes planting stubble, and is equipped with key technologies such as intensive seedling cultivation, plastic film fixed hole high box cultivation, scientific balanced fertilization, and precise pest prevention and control Dr. Miao Mingjun, an expert in the high-altitude vegetable position of the Sichuan Vegetable Innovation Team, weighed the mature chili fruits while taking a break from his busy schedule and introduced that this model effectively utilizes the light, heat, and land resources of Zengjiashan, changing from one season per year to two seasons per year. The technology is highly mature, with significant increase in production and efficiency. The prospects are very broad, and the planting willingness of the people is also very strong.
Cai Wanping, the head of Huinong Vegetable Professional Cooperative, has the most say in the yield and income increase effect of the “early spring cabbage+summer chili pepper annual efficient planting model”, He was overjoyed and said, “This year, the cooperative has adopted this model on a total of 60 acres of land, with an average output value of 10000 to 12000 yuan per mu. Compared to the previous season of vegetables, the income has doubled. Moreover, scientific rotation of different vegetable types can not only fully utilize soil nutrients, suppress disease and pest occurrence, improve land use efficiency, but also significantly increase vegetable production and efficiency.
To achieve stable yield and abundant harvest of vegetables, agricultural technology is indispensable. In recent years, Chaotian District and Sichuan Academy of Agricultural Sciences have jointly established the Northeast Sichuan Mountain Vegetable Expert Courtyard, established two vegetable technology demonstration bases in Zengjia Town and Lianghekou Town, formulated the “Zengjia Mountain High Mountain Open Field Green Vegetable Production Regulations,” introduced more than 100 demonstration new vegetable varieties such as eggplants, melons, and leafy vegetables, promoted 13 new vegetable varieties on a large scale, and promoted the “five changes and one addition” high yield and efficient cultivation of chili peppers Six technologies, including high-quality and high-yield cultivation of grafted eggplants, high-yield and efficient cultivation of protected tomato under rain, soil remediation and improvement, and green comprehensive prevention and control of pests and diseases, as well as four planting models, including chili pepper+corn, cabbage+zucchini, have provided strong technological support for improving the quality and efficiency of mountain vegetable industry, transformation and upgrading, and increasing farmers’ income and wealth.
At present, the annual multiple planting area of vegetables in the high mountain open field of Zengjiashan is nearly 260000 acres. In 2022, the vegetable production of the base is 750000 tons, exported to over 60 large and medium-sized cities such as Chengdu, Chongqing, Xi’an, Guangzhou, and Shanghai, with an annual output value of nearly 1 billion yuan; The per capita vegetable income of farmers in Zengjiashan has reached over 14000 yuan, accounting for over 70% of the total per capita income of vegetable farmers. Zengjiashan has become the largest summer and autumn green vegetable production and supply base in the Sichuan Shaanxi Chongqing region, and has been awarded the titles of “National Green Food Raw Material Production Base”, “Hometown of High Mountain Ecological Vegetables in China”, “National Green Agriculture Demonstration Zone”, “National Key Vegetable Production County”, and “Pilot County (District) of Sichuan Province Vegetable Base for Hong Kong and Macao”.
