The latest application method of carbon dioxide gas fertilizer for grape in greenhouse
The main raw materials for plant photosynthesis are carbon dioxide and water. The organic matter and starch produced by photosynthesis are precipitated in the plant as nutrients for plant growth. Therefore, the quality of photosynthesis also affects the growth and development of plants. Today, Portugal

Physiological diseases of garlic bolts: carbon dioxide toxicity
In the later stage, the carbon dioxide content of garlic bolts packaged in thin film bags is too high, which often leads to poisoning, showing yellow spots on the stalks, gradually sinking, connection, tissue necrosis, water-stained rot, and finally garlic bolting broken strips, sometimes bolting bud necrosis, giving off alcohol smell, accompanied by stench. Seriously, the whole bag of garlic vines rotted away, which has become an important disease in the storage of garlic bolts. Garlic bolts controlled atmosphere storage, general carbon dioxide should not exceed 5%, should be regular ventilation, later carbon dioxide more than 13% will be poisoned.

Carbon dioxide and carbonic acid assist live fish transport
Carbon dioxide-assisted live fish transport is a new technology that keeps live fish asleep for a long time to reduce transportation costs. When carbon dioxide is used to assist the transport of adult carp, the adult carp must be alternately perfused with carbon dioxide gas containing high partial pressure (27-33KPa) and low partial pressure (13-17KPa). The transportation time can be maintained for about 10 hours, and the mortality rate is very low. The transport of live fish can also be assisted by a mixture of carbon dioxide and oxygen (50:50). At this time, you can go directly to the crucian carp and

Environmental Management of Apricot cultivation in protected area
The main results are as follows: 1. for the control of temperature and humidity, three thermometers are hung on the east and west sides of the shed and in the middle of the shed, which are about 1.5m above the ground. The general thermometers and the highest and lowest thermometers can be placed respectively. The temperature is recorded at 8 o'clock, 12:00, 14:00 and 20:00 every day during the budding period, and observed every 1-2 hours during flowering. The air humidity in the shed can be measured by a dry-wet bulb hygrometer. The suitable temperature and humidity of each phenological period are as follows: the regulation of temperature is mainly achieved by opening and closing vents. Before and during flowering, if the temperature does not reach

Carbon dioxide storage method of Lentinus edodes
The use of carbon dioxide (CO2) hypoxia insecticidal method can make the storage of Lentinus edodes not affected by the natural climate, no insects, no mildew, no deterioration, and ensure the supply of the market all the year round. First, the use of polyethylene film to make a sealed cover, the size of self-set, generally can hold 5 Mui 10 tons is appropriate. The cover is square and there is a check hole at the top. When stacking, untie the mouth of the bag of Lentinus edodes and grow square or square. The pile is divided into three layers, the bottom layer is moisture-proof agent, the middle layer stores Lentinus edodes, the upper layer puts moisture-absorbing agent, and then the cover is sealed.

Storage and fresh-keeping Technology of Golden Pear
1. Key points of storage technology 1.1 timely harvest of golden pears in North China is from September 20 to 30. At this time, the fruit has matured, the nutrients are fully accumulated, and the storability is the best. Early harvest (September 10) the decay rate of pear fruit was high during the whole storage period, and the pericarp was easily browned. When harvested too late (early October), brown scald occurred seriously during storage (18.94%). Special attention should be paid to avoid bruising in the process of harvesting. 1.2 the purpose of grading fruit crystal classification is to standardize the commodity. I

How to store garlic bolts in winter
Temperature management of storage garlic belongs to the plant with strong cold resistance, and the garlic stalk, as the flower stem of garlic, still has strong physiological cold resistance. When the storage environment temperature reaches its freezing point, the fresh-keeping effect is the best. The freezing temperature of garlic bolts is-0.8 ℃ 1 ℃ (depending on the content of solids). The freezing temperature of garlic bolts higher than-0.8 mol / L will not cause tissue icing, so it is safe. According to various practical experiences, the cold storage index of garlic stalk at storage temperature is recommended to be-1-0 ℃, which should be reduced as much as possible in this range.
