指着大棚里的新装备告诉记者:“这是补光灯,过去这个生产季,俺每天补光3小时,阴天补到6到9小时,西红柿提早上市5天以上,产量增幅在两成以上。” Recently, in the village of Xingjia Maotuo, Taitou Town, Shouguang City, Shandong Province, the greenhouse grower Song Yiliang pointed to the new equipment in the greenhouse and told reporters: "This is the fill light. In the past production season, I supplemented the light for 3 hours a day. The days are up to 6 to 9 hours, and the tomato market is more than 5 days in the morning, and the output increase is more than 20%. "

In Song Yiliang's cucumber greenhouse, there is also a special set of equipment-ground temperature adjustment equipment. Its structure is similar to a drip irrigation pipe, which is composed of a main pipe + a branch pipe + a vent hole. As we all know, vegetables are breathing at all times, generating heat, and these heat are increasing, causing the temperature in the shed to rise gradually. Therefore, even in winter, farmers open the greenhouse vents every day to dissipate heat. Now turn on this set of temperature control equipment, you can transfer the heat in the gas in the shed to the soil through the pipeline, and then raise the ground temperature. The test proves that the ground temperature can be increased by 1.7 ℃ for 2 hours. Increased ground temperature is conducive to the development of vegetable root systems and promotes increased yield.

New physical agriculture technology breaks "overcast obstacles"

Enter the vegetable greenhouse of Song Yiliang, a vegetable farmer in Songjia Daozhuang, Daotian Town, Shouguang City, turn on the switch, and above the rows of green cucumber plants, a group of LED fill lights will be lit up. Under the ground, there is also a special set of ground temperature adjustment equipment, which is composed of temperature regulator + main pipeline branch pipeline + ventilation holes. "We used these two technologies in December 2016. The cucumber picking time was advanced by 10 days, and the output increased by more than 20% to 30%, and we can earn an extra 10,000 yuan per season." Song Yiliang said.

Ding Xiaoming, deputy director of the facility agriculture research institute of the Planning and Design Research Institute of the Ministry of Agriculture and Rural Affairs , said that in the production of facility vegetables, supplementary light and heating are the main ways to improve the yield and quality of vegetables, but supplementary light and heating will inevitably increase energy costs. . Therefore, it is of great significance to make full use of the temperature and light coupling effect of vegetable crops and formulate an appropriate temperature and light management strategy to reduce the energy consumption and increase the yield and benefit of vegetable production in facilities. The research of Yisheng Physical Agriculture is based on the inter-plant LED light supplement technology and air source heat pump root zone heating technology. It is applied to the production of facility vegetables. After practice tests, for the growth of strong plants, the market can be released in advance to increase yield and quality, and strengthen pests and diseases. Etc. have a certain effect.

Talking about the operating principles of these two sets of equipment, Pan Haoqin, the research principal of Weifang University of Science and Technology, said that at present, the biggest bottlenecks that restrict the production of vegetables in facilities in the north are low temperature, cloudy, haze, rain and snow, which cause light and heat in the shed Insufficient conditions, slow plant growth, and sharply reduced yields can be referred to as "continuous cloudy obstacles" in vegetable production in northern facilities. Using LED fill light to supplement the light of vegetables according to the light source needed for plant growth can solve the problem of “weak light” and achieve the purpose of extending the light time and increasing production and efficiency. With the use of ground temperature adjustment equipment, the excess heat source in the air in the shed can be used to transport the soil to the soil through pipes to raise the soil temperature and solve the problem of "low temperature at the root". Decreasing air temperature in the shed, increasing ground temperature, and accelerating air circulation will also help curb disease occurrence and solve the "disease" problem.

Based on Shouguang's "Ministry-Institution-Enterprise Cooperation" to accelerate the implementation of advanced technologies

As Shouguang's earliest farmer who used the new technology of physical agriculture, Song Yiliang learned quite well: "The more it encounters rain and snow and cloudy days, the more obvious it will be with the fill light and geothermal equipment. At this time, most greenhouses have low yields, so vegetables The price is high. We rely on these two new equipments and the output is guaranteed, so the effect of increasing income is particularly obvious. "

How can good technology accelerate the promotion? In September 2017, the Institute of Facility Agriculture of the Planning and Design Institute of the Ministry of Agriculture, Weifang University of Science and Technology, and Yisheng Physical Agriculture signed the "Agreement on Production, Study, and Research Cooperation" to promote the "Ministry-Institute-Enterprise Cooperation" to jointly improve and promote these new physical agricultural technologies. "Since the cooperation, the team is exploring a number of experiments to explore specific implementation standards such as light quality, light intensity, light supplement time, light supplement duration, and light installation location for different crops such as cucumbers and tomatoes at different growth stages. And evaluate the effect, and then formulate the technical rules for LED light supplement in solar greenhouses, so as to promote it on a large scale. "Pan Haoqin said.

"As of now, our physical agricultural technology has been applied to the production of facilities vegetables, edible fungi, blueberries and other fruits, and the effect of increasing farmers ' production and income is obvious. In order to accelerate the experimental popularization of physical agricultural technology, we have adopted a test base built in farmers' greenhouses. In the method described here, farmers only need to pay a certain deposit, and we will install half of the equipment in their greenhouses free of charge. The comparison on site highlights the use effect. "Said Chang Yutang, chairman of Yisheng Physical Agriculture Company.

Yang Lanfang, deputy secretary-general of National Semiconductor Lighting Engineering Research and Industry Alliance, introduced that artificial light environment is a very important part for facility agriculture. LED agricultural lighting is also listed as one of the key special contents of strategic advanced electronic materials in China. Yisheng Physical Agriculture is based on the Shouguang facility vegetable industry foundation, and plays the leading role of Shouguang's “Silicon Valley of Facility Vegetable Industry”. It uses advanced physical technology and “grounding gas” to promote the implementation of new physical agricultural technologies. It can not only benefit Shouguang vegetable farmers, but also lead Facility vegetable industry transformation and upgrading.
