The shed is a warm space where structures are combined with the membranes, so that the carbon dioxide savings can keep the temperature warm. Higher temperatures can be used to grow vegetables that cannot be grown in the current season when local temperatures are low. Anti-season planting is one of the greatest advantages of margarine cultivation, but there are also some disadvantages, such as vulnerability to obesity and medicine. So management has to capture these critical practices。
I. Cultivation management
1. Temperature regulation
The winter is cold and must be warm, with little ventilation, but at night co2 concentrations will rise, and the vegetables will grow the most, and there will be need for sufficient oxygen, so it is important to have the skylight through the sun. This does not reduce the temperature in the shed too much. In the summer, the shed can be opened at both ends of the daytime, and the cooling at night can be closed, without cooling, and can be ventilated. The internal temperature regulation is also adjusted to external temperature。
2. Humidity
The sheds are drought-prone, but they are wet and oversized, to the detriment of vegetables. So water can't be poured too much at a time, because the water is distributed more slowly. It would be preferable to choose drip irrigation, bearing in mind the choice of drip-proof film, so that it does not drip on vegetables and is susceptible to disease, especially decomposition. But it can't be done without water, and dripping is the best way。
3. Lights
In order to choose a better radiance rate, vegetables in general require sufficient sunlight, but sometimes some vegetables can be softened, such as tungsten, which is to be treated in darkness over a period of time, so that their mouths can be softened and tasted。
Ii. Notes
Fatty
Long-term drip irrigation, no rainfall, no running water irrigation, long planting periods, and unexploded fertilizers accumulate in the soil, which tends to increase soil concentrations, affect the absorption of roots, fail to absorb nutrient moisture and harm root systems. Finally, it's a swap. Crop rotation。
2. Drugs
Because of space constraints, effective pesticide methods such as fumigation are susceptible to pharmaceutical hazards and pesticide residues in soil and harmful to vegetable growth. It would therefore be preferable to pay attention to pest prevention and to reduce the use of highly toxic pesticides. Choose the protective agent and spray as much as possible。
There are advantages and limitations to maroon cultivation, but it can be continued as long as the advantages outweigh the disadvantages. It is also likely that the production technology will be optimized. The main management of vegetable production in the sheds would be simpler than in the field。
