Cultivation Techniques of Cucumber and Lettuce in Sunlight Greenhouse

1. Nursery. Cucumber: Grafting cultivation of greenhouse cucumbers is a major feature here. Black-skinned squash are commonly used as rootstocks and Changchun quills are used as scion. Plug method. The cucumber was sown in late December and the black-skinned pumpkin was sown 7 days earlier than the cucumber. At the time of grafting, the pumpkin was first picked up and about 1 cm below the leaves of the cucumber seedlings. The direction of the straight leaves was cut by a knife on both sides to form a "wedge" shape. The rootstock was chopped with a sharp hole at the original growing point, and the treated cucumber seedlings were inserted so that the two were well aligned and closely matched. After the picking, the rootstock plants and scions were of “10” shape. The well-grafted seedlings were placed in a small arch shed erected in advance, and the foot of the arch shed hit the bottom water. Maintaining sufficient humidity and temperature in the shed was the key to survival. Shed temperature is about 28°C during the day, 18~20°C at night, and relative humidity is more than %%. The first three days at noon with shady grass (or paper, etc.) shading, to facilitate the healing of cucumber and pumpkin vascular bundles. Generally 7 days after the cucumber grows true leaves, began to vent the wind hardening seedlings, remove the arch film after 8 to 10 days, the temperature during the day around 35 °C, about 15 °C at night, the emergence of rootstock buds should promptly erased. In the middle of growing seedlings, it is necessary to properly move the earth to facilitate the illumination. Can spray 0.1% potassium dihydrogen phosphate 1 to 2 times. One week before planting, the seedlings should be descended to adapt to the post-planting environmental conditions. When the temperature of 10 centimeters reached 10 degrees Celsius, a boat age of 45 days, planted in mid-February. Before the planting, the ditch was laid at a spacing of 40 meters, and the seedlings were planted at a spacing of 20 centimeters. A small amount of soil was used, and then watered with a pot or a rubber hose.

2. Colonization. Lettuce: greenhouse box seedling sowing, 667 square meters with a seed amount of 50 grams, broadcast 8 square meters, after sowing covered film, temperature 20 ~ 25 °C. 18 ~ 20 °C after emergence, 8 ~ 10 °C at night. Seedlings once a seedling, 3 cm 3 cm row spacing. 6 to 7 leaves when planting, ridge planting. Plant spacing 20 cm 20 cm, planting double rows per ridge. When planting water hose, 5 to 6 days seedlings. General planting is about 20 days to pour water, and 667 square meters of ammonium nitrate 15 to 20 kg. The market can be harvested in mid-March, and each can grow to about 0.5 kg.

3. Post-planting management

Cucumber: After the planting, the greenhouse is closed, a good stove is produced, and the temperature is increased to promote seedlings. About 30°C during the day, 32°C began to release air, 20°C or so at night, 16°C to 14°C in the middle of the night, and dropped to about 12°C in the middle of the night to promote nutrient conversion and reduce nutrient consumption. Adjust the room temperature and humidity by heating and watering. At the same time, it is necessary to reduce the temperature and humidity by releasing air. Before the root melons sit, they will no longer water the water except for watering the seedlings. In order to enter the sacred melon period, we must follow the principle of “eat less and more meals”, timely watering, and top dressing.

Anti Inflammation Material

Aspirin [Aspirin, 2-(acetoxy) benzoic acid, also known as acetylsalicylic acid] is a white crystal or crystalline powder, odorless or slightly acetic acid odor, slightly soluble in water, easily soluble in ethanol, can be Soluble in ether and chloroform, the aqueous solution is acidic. This product is a derivative of salicylic acid. After nearly a hundred years of clinical application, it has been proved that it has a good effect on relieving mild or moderate pain, such as toothache, headache, neuralgia, muscle pain and dysmenorrhea. It is also used for colds, flu, etc. Relieving fever of febrile diseases, treating rheumatism and so on. In recent years, it has been found that aspirin has an inhibitory effect on platelet aggregation and can prevent thrombosis. It is clinically used to prevent transient ischemic attack, myocardial infarction, artificial heart valve and venous fistula or other postoperative thrombosis.
