In the scorching summer, it's the season of passion fruit again. In recent years, the passion fruit produced by Baisha has been sought after by the market, and Rongbang Township, which has tasted the sweetness, has vigorously developed and expanded the passion fruit industry, and the small passion fruit has produced the "rich fruit" of rural revitalization.
Today, Baisha passion fruit has further expanded its planting area, and farmers are becoming more and more confident. "Now that it's fruitful, what should I pay attention to?" "How should fertilizers be used? Which one is appropriate to use now? How to use the ratio? In the Baisha Rongbang Agricultural Products Trading Center, the grower Brother Xiong is seeking advice from Fang Chuanying, the instructor of the Baisha Passion Fruit Science and Technology Academy and an associate professor of Hainan University.

Brother Xiong relied on experience in farming in the past, but now he relies on the science and technology academy and the intellectual support of institutions of higher learning, and his passion fruit business is getting better and better year by year.
Hand in hand with institutions of higher learning, farming also depends on "brainstorming"
In recent years, with the increasing demand for healthy foods, passion fruit has gained popularity due to its rich nutritional value and unique taste. Rongbang Township, Baishali Autonomous County, is located at 19 degrees north latitude, and the climate, light and rainfall are suitable for the cultivation of passion fruit.

"In 2019, we began to study passion fruit, and in 2020, we officially settled in Baisha, writing scientific research and practice on the land." Fang Chuanying led the team to Baisha and found that the villagers planted passion fruit in an extensive management style, and the old varieties of passion fruit were selected, and the quality of the harvested fruit was low, and the market response was average.
"Flavor and nutritional quality need to be improved" "Why is passion fruit unique in flavor and nutritious?" How can it be more delicious and nutritious? ”...... With a series of questions raised, the scientific researchers of the Science and Technology Academy began to attack one difficulty after another. In 2020, it actively carried out aerospace breeding, with about 40,000 aerospace breeding groups. Introduced "Qinmi No. 9" with low acidity and high sweetness from Guangxi...... This year, under the technical guidance of the small courtyard, the threat of pests and diseases in the passion fruit plantation has been significantly reduced, laying a solid foundation for the healthy growth of fruit trees. In order to further improve the yield and quality of passion fruit, the park has introduced cutting-edge passion fruit light supplementation technology, which not only shortens the growth cycle of passion fruit, but also achieves good economic benefits. Under the precise control of light, the passion fruit in these areas blooms and bears fruit more than 30 days earlier than the traditional planting method, which not only means that the production cycle is shortened, but also brings a significant increase in yield. Secondly, the science and technology institute has promoted the green ecological production model, and reduced the use of pesticides and fertilizers, environmental pollution and production costs by optimizing management measures such as fertilization and irrigation.

"According to preliminary estimates, in the first half of this year, the output of passion fruit in the area of light filling increased by nearly 20% year-on-year. At the same time, under the careful care of the light technology, the color of the fruit is brighter, the taste is sweeter, and the output value has also shown a double-digit growth. Hearing the results achieved by the scientific research team of the Science and Technology Academy, Brother Xiong, who has been dealing with agriculture all his life, said with emotion: "It turns out that the planting industry also needs brainstorming. ”
Compared with the traditional planting method, the scientific and technological achievements applied by the Hainan Baisha Passion Fruit Science and Technology Institute are more advanced and scientific. These scientific and technological achievements not only improve the yield and quality of passion fruit, but also reduce production costs and environmental pollution, bringing tangible benefits to local farmers.
Rooted in the base to solve problems in the field
At present, it is the season when passion fruit is ripe and on the market, and I walked into the passion fruit planting base in Lingwei Village, Rongbang Township. Under the green vines, round and plump fruits hang on the branches.
Associate Professor Fang Chuanying took two students to check the fruit hanging in the orchard. Ni Shihao and Wang Lu, master's degree students in agromy and seed industry at Hainan University, with swarthy faces and sun-protective clothing, skillfully do farm work in the fields, not at all like college students in ivory towers.

"Every time the shelves are full of green passion fruit, I feel a sense of accomplishment in my heart." Ni Shihao proudly said that recently, the small institute was selected as the "most beautiful science and technology academy" of the China Agricultural Technology Association, and he was also awarded the "most beautiful graduate student". In terms of scientific research, he participated in the research and application of passion fruit pest control technology, and proposed measures such as changing the spraying time of pesticides and hanging sticky insect boards to protect the healthy growth of fruits in view of the difficult control of thrips in Hainan.
"In 2023, 80% of the first batch of fruits showed signs of thrips bites, so that buyers will lower the price when they come to buy. After taking measures, this year's fruit is largely free of signs of bites. Ni Shihao often uses simple explanations to popularize modern agricultural science and technology knowledge for farmers, so that more and more farmers support and understand their work, so that many growers not only learn professional knowledge, but also "money bags" are becoming more and more bulging.
"Now you see that we are proficient, but I have never seen passion fruit before, let alone planting technology." Another student, Wang Lu, said that after taking root in the field, he realized that planting fruit trees is not a simple matter of digging pits and planting seedlings, watering and fertilizing them for harvest. There is a depth of digging pits, spacing for sowing, and watering in the morning and evening, and each of these items needs to be practiced to achieve true knowledge.
"The science and technology courtyard set up in the countryside and villages, students stay for more than 200 days a year." Associate Professor Fang Chuanying introduced that he led the entire scientific research team to follow the agricultural time, and he had to go to the field every three or five days to observe the growth of crops, and he could not go home during the holidays, and it was normal to face the loess with his back to the sky. Because agriculture depends on the weather for food, there are too many uncertainties, and often a sudden rainstorm destroys the "experimental results" of the team's efforts.
Let the "Fruit of Prosperity" be full of scientific and technological elements to help rural revitalization
Hainan is the earliest production area of passion fruit in the country, but compared with the main producing areas of the country such as Guangxi, there is only a window period of about a month, and this window period is easily affected by the heavy rain in June. In terms of production, if the passion fruit harvest date can be advanced by half a month, the window period can be extended and the losses caused by the rainy season can be reduced. Since the establishment of Hainan Baisha Passion Fruit Science and Technology Institute in 2022, Hainan Tianhehe Agricultural Development Co., Ltd. has been promoting the scientific and technological innovation and development of the passion fruit industry. "The science and technology courtyard and the company have explored the effect of supplementing light and promoting flowers." Associate Professor Fang Chuanying said. Small-scale trials have shown that light can advance passion fruit's flowering and harvesting by more than a month, and they are currently investigating the physiological and molecular mechanisms behind it.

Hainan Tianhehe Agricultural Development Co., Ltd. has been taking passion fruit as the core product, with the support and coordination of the Baisha County Party Committee and the county government, in Lingwei Village, Rongbang Township, the company leased 407 acres of planting base and began to plan the planting of passion fruit. At this stage, the company not only focused on soil improvement and the introduction of planting technology, but also had an in-depth understanding of the local climate, water and other natural conditions to ensure that passion fruit can thrive on this land. In addition, the company also attaches great importance to scientific and technological innovation, and the Science and Technology Academy was established in close cooperation with Nanfan College of Hainan University and Baishali Autonomous County Science and Technology Association. This science and technology courtyard has also brought cutting-edge agricultural technology and management experience to the company, and promoted the innovation and improvement of passion fruit planting technology.
As a socially responsible enterprise, Tianhehe Company gives priority to hiring local villagers to participate in the construction and management of the base, providing employment opportunities and income sources for the villagers. At the same time, the company also carries out technical training and guidance through joint science and technology institutes, science and technology associations and other organizations to help villagers improve their planting skills and management level, and achieve the goal of helping farmers increase income. In addition, the company also actively plays a demonstration and leading role to guide local farmers to expand the scale of planting, improve planting technology and management level, and share the dividends of industrial development. This not only promotes the development and growth of the local agricultural industry, but also drives the villagers to get rid of poverty and become rich. Brother Xiong, a passion fruit farmer, told reporters: "I am planting more and more acres of passion fruit, and through the guidance of experts, passion fruit is growing well, and this year's estimated income has reached hundreds of thousands of yuan." ”
"Haida has a strong faculty and strong scientific research strength, especially in tropical agricultural research, which has a significant advantage, and has a high degree of recognition and influence in the region. According to the staff of the Baisha Association for Science and Technology, the scientific research team of the Science and Technology Academy has solved the technical problems of agricultural production, especially the problems of pests and diseases, yield and quality in passion fruit planting. Baisha will strive to make the passion fruit industry bigger and stronger, and use the incubation period of the science and technology courtyard to form a number of agricultural technologies that can be replicated and promoted, so as to increase agricultural production and efficiency, and promote farmers' income and rural revitalization. ”
