In recent years, the production of domestic greenhouses has been developing rapidly, and the benefits of agricultural production have been significantly improved. However, the potential for greenhouse production has not been completely excavated. It is the desire of every farmer to increase production, but it is first necessary to find out the root cause of limiting output increase. According to our investigation, at present in China, the two major contradictions in the greenhouse production in winter are serious shortage of light and carbon dioxide. First of all, the winter sunshine time is short, generally only 6-7 hours of effective light, about half of summer, most of northern China is an East Asian monsoon climate zone, it is prone to low temperature and sunshine, effective sunshine will be further reduced, when severe will become disaster. Carbon dioxide is one of the indispensable raw materials for photosynthesis of plants. The optimum carbon dioxide concentration for crop growth is 1500-3000 ppm, and the average concentration of carbon dioxide in the air is 330 ppm. Under the greenhouse enclosed environment, sunny day carbon dioxide concentration drops to 85 ppm, and greenhouse carbon dioxide is severe. insufficient. Since light and carbon dioxide are both necessary conditions for photosynthesis of plants, the two are mutually restrictive and indispensable. Energy efficient greenhouse rare earth fill light lamp was successfully developed by the Infrared Technology Research Institute of Harbin Engineering University. It was evaluated as a national key new product in 2005 by four ministries and commissions such as the Ministry of Science and Technology. Straw reactor is the most convenient and inexpensive method for generating carbon dioxide. The impact of rare earth-filled lamps in the greenhouse on the yield of vegetables combined with the use of Strawwood bioreactor technology. In 2006, we arranged trials in Xinglong Village, Qianquan Office, Zoucheng City, Shandong Province, and Wuguan Village, Beisu Town. First, test materials and methods 1. Test material: Zhang Zhaolin's straw bioreactor in the greenhouse uses 3000kg of corn straw, 6kg of bioreactor special bacteria, 120kg of wheat bran, one exchanger, and one gas conveyor belt; HGH - High-efficiency energy-saving greenhouse rare earth fill light 6 Hey. Feng Zuobin Greenhouse Zhongxuan Bioreactor uses 3000kg of corn straw, 6kg of special bioreactor strains, 120kg of wheat bran, one exchanger, one gas conveyor belt, and a high-efficiency energy-saving greenhouse rare earth light bulb. . 2. Test method: On November 1st, 2006, at the Thousand Springs Office, Zhang Zhaolin of Xinglong Village began using the external Strawhorn bioreactor technology and the rare earth supplemented light application test on the greenhouse squash of the Xinglong Village Zhang Zhaolin. Grafting pumpkin seedlings, sowing date for October 3, October 27 colonization, plant spacing 50cm × 60cm, acres of planting 2223. The construction of the external reactor and the treatment of the strains are the same as the general management. The air supply will be vented for 4 hours per day. The rare earth fill light fills the light for 1 hour before sunny day and before closing the shelter on sunny days; 6 hours for rainy and snowy days, and the remaining measures are managed according to general techniques. Feng Zuobin’s cucumber variety was Jin Qiu. He was transplanted with black-skinned squash seedlings on October 5, 2006. He was planted on November 10, harvested on December 3, and pulled on May 20 of the following year. The row spacing was 30cm×50cm～70. Cm, acres of planting 3705 strains. The construction of an external reactor and the treatment of strains are the same as the general management. The air supply is vented for 4 hours per day. The rare-earth fill light fills up the light for 1 hour before sunny days and before closing the shelters on sunny days; it fills light for 6 hours on rainy and snowy days, and the remaining measures are managed according to general techniques. Zhang Zhaolin's 61-meter long Yingan 12-inch lamp. We only applied 6 rare-earth lamps and a C02 gas treatment at the East Gate, and Li Minglin’s courgette shelter was used as a control instead of a reactor and a fill light. Both Li Minglin and Zhang Zhaolin planted summer squash for many years. Their technical level is similar, and their varieties and cultivation management measures are the same. In Feng Fengbin's 48m shed, there should be 10 lights in Ying'an. We also took the same measures to arrange the test, and only tested the ventilation in the 5th light of the east half of the greenhouse. The cucumber shed of Wang Weihai with similar cultivation techniques and conditions was used as the control C.

Third, the conclusion From the above data, we conclude that the use of Strawhorn bioreactor technology combined with rare earth fill lamps in greenhouse vegetable production can significantly increase production by 40-50%. The Strawhorn Bioreactor increased the carbon dioxide concentration in the shed, and the rare earth supplemented light added light to the vegetables. The two complement each other, avoiding the low photosynthetic efficiency of vegetables due to insufficient light in the greenhouse or insufficient carbon dioxide, and solved the current greenhouse production. There are key issues. Since 2006 is a warm winter, the control group is not significantly affected by the weather. If there is low-temperature illumination, the gap between the two will be expected to increase further. The use of supplemental and supplementary carbon dioxide measures will ensure the greenhouse under any climate conditions. Steady production and high yield. The economic and social benefits of this method are also very obvious. 2. Social Benefits: In recent years, Shandong Province has won the singer's wind, which not only causes the waste of resources, but also seriously pollutes the environment. This method can effectively use the straw shed and turn waste into treasure. Moreover, due to increased land capacity, it can replace chemical fertilizers and provide favorable conditions for the production of green food and the establishment of a green food production base. i.. 3. After the seeds are buried in the ground, due to the effect of slow oxidation, the cumulative ground temperature can be increased by 4~6°C. At the same time, the fill light can increase the temperature of the shed's steam 2~3°C, which is beneficial to the growth of the crops, especially to the tomato plants. The fruit crops are more favorable and can effectively prevent disasters caused by low-temperature and low-light illumination and ensure the production of greenhouses is safe. To sum up, the adoption of the Strawhorn bioreactor plus rare earth fill light method is a practical method that requires less investment, produces significant yield increase, and does not involve any risk, and should be vigorously promoted. The Institute of Infrared Technology of Harbin Engineering University promotes and popularizes this technology, providing greenhouse light and straw bioreactor strains at preferential prices, and provides technical guidance free of charge.
