Right now，Located in the Science and Technology Yard of bet365 online games College in Nanzhuangying Village, Cuicun Town, Changping District，Tomatoes in more than ten sheds are going through the critical color change and fruit expansion period。Taking advantage of the Spring Festival holiday，Dean of the College of Agriculture、Duan Liusheng, leader of the Huang Danian-style teaching team in universities across the country, led teachers and students into the Science and Technology Courtyard，Sending technology and popular science，"Check the pulse and prescribe prescriptions" for growers。

Duan Liusheng teaches farmers the knowledge of winter greenhouse tomato cultivation

"Winter cultivation of tomatoes，The most important thing is thermal insulation，25℃ to 28℃ is most suitable。”Going into the greenhouse from the cold outdoors，A thin layer of water mist instantly covered the spectacle lenses，Duan Liusheng took off his glasses and wiped them with a tissue，While walking towards the corner of the greenhouse，“The further you walk to the edge, the colder you feel，The temperature difference in the shed is too large，This kind of environment is not conducive to the bet365 bet365 online games sports betting livegrowth of tomatoes。"As Duan Liusheng said，The tomato branches and leaves in the corner of the greenhouse are turning yellow，The growth trend is obviously weak。The thermometer display hanging on the shed wall，The temperature in the shed is less than 20 degrees Celsius at this time。

“The weather forecast says it will cool down again recently，This winter is difficult。"Grower Ren Changqing came forward，Please help Duan Liusheng to recruit children。

“The top priority is to increase the temperature inside the shed，Let the leaves and fruits fully receive light。Color change and fruit expansion period，Absorbing nutrients is crucial。"Duan Liusheng squatted down and picked up a handful of soil，Put it in the palm of your hand and rub it，Asked: "Are you still watering the normal amount recently?"？You should water enough in the morning when the temperature drops，Spray some water on the plants，This prevents frost particles from forming in the soil，And the condensation of water vapor in the air can also release heat，Raise and maintain temperature。”

Subsequently，He looked towards the lower stem closer to the ground，It’s lush here，You need to remove the branches and leaves to see the fruits。He wants a pair of pruners，Just listen to a few "click, click, click" sounds，The branches and leaves fell off one after another。Ren Changqing felt a little distressed: "Cut so much，Will it affect growth？What a pity。”

Duan Liusheng explained the knowledge point with a smile: Let the leaves increase，On the contrary, it will affect the growth of fruits，“Excess leaves bet365 bet365 online games sports betting appand side branches will not only absorb nutrients that should be supplied to the fruit，It also blocks the light like an umbrella，Easy to cause similar uneven color transfer。"He picked a tomato casually，Use your palms to block the light。This fruit, which is in the veraison stage, is all green and yellow，Only a small area of ​​skin is red。

"Speak slowly，Let me remember” “The cucumbers in my greenhouse are always affected by diseases and insect pests，Please help me take a look" "I hope there are new varieties that we can try planting"...I heard that a university expert came to the plantation，Growers from other greenhouses also gathered around，Request "pulse test"。This on-site teaching class was originally planned to be 1 hour，One lecture lasts an entire afternoon。

Ren Changqing has been holding up his mobile phone to record videos，Don’t miss any knowledge point。He smiled and said: "Tomato freeze damage has always been a problem for me，This time we invite experts from universities to give lessons，Learned a lot，Special thanks。”

Introduction to Duan Liusheng，Beijing Agricultural College not only delivers technology to growers，We also introduced the aluminum foil soilless cultivation technology independently developed by the school to the science and technology courtyard、New high-quality vegetable varieties independently bred。Currently，The school has built a modern comprehensive park of about 200,000 square meters in Nanzhuangying Village，Collect sightseeing agriculture、Farming experience bet365 bet365 online games sports bettingin one，Helping farmers increase their income by more than 15% every year。"As a capital agricultural college，We will use our talents、Technological and intellectual advantages，Relying on Science and Technology Courtyard、Doctor’s Farm, etc.，Carry out in-depth work to support agriculture，Empowering rural revitalization with technology。”
