Zucchini Organic Soilless Culture Technology

I. Facilities

1. The cultivation trough left 80cm walkway in the north of the greenhouse, and left 30cm in the south, using a brick barrier to form a north-south cultivation trough, the trough diameter is 48cm, the trough height is 24cm, and the trough distance is 72cm; it can also dig semi-underground cultivation trough directly, the trough width is 48cm , 12cm deep, on both sides and then use the brick barrier 2 layers. A 0.1 mm thick plastic film is laid in the tank and pressed on both sides with the uppermost brick. A 3cm thick clean river sand was laid on the membrane, a layer of woven bags was laid on the sand, and the cultivation substrate was placed on the bags.

2. The water supply equipment uses tap water or water tanks with a water level difference of 1.5 meters or more to supply metal pipes for external pipes, and the main pipes in greenhouses and drip irrigation belts in the cultivation tanks all use plastic pipes. 1 to 2 drip irrigation belts are installed in the tank, and a thin plastic film 0.1 mm thick is coated on the drip irrigation belt to prevent drip irrigation from spraying.

3. The raw materials used to cultivate the matrix organic matrix can be corn stalks, mushroom residues, sawdust, etc., and the matrix is ​​first used to spray wet film for 10 to 15 days to sterilize and add a certain amount of inorganic substances such as sand and slag, 1 In the cubic meter matrix, add 2 kg of organic soilless cultivation special fertilizer and 10 kg of chicken manure. After mixing, fill the trough. After each crop is harvested or the matrix is ​​disinfected, the matrix is ​​generally updated 3 to 5 years.

Second, before planting and colonization, the substrate shall be leveled and leveled, and the matrix in each cultivation tank shall be flooded with water so that the matrix can absorb water sufficiently. After water infiltration, 2 rows were planted in each trough, and the substrate was slightly higher than the base of seedling shoots. Plant spacing is 45cm, 2000 plants are planted per 1/15 hectare (1 acre), and light water is poured after planting.

Third, management

1, fertilizer and water management generally planted 5 to 7 days after pouring 1 water, to maintain the matrix moist rhizosphere, so that the medium growth of zucchini, fruit after sunny morning and afternoon pouring 1 time; cloudy days can be depending on the specific circumstances of less water or not pouring; Generally start 20 days after planting, and then topdressing once every 10 days, each applying 15 grams of special fertilizer, 25 grams per plant per fruit. Spread the fertilizer evenly 5cm away from the root. In the greenhouse, you can apply carbon dioxide gas fertilizer as required.

2, temperature, light management after planting, the temperature is maintained during the day 20 ~ 25 °C, about 12 °C at night. After sitting in the melon, keep it at 25-28°C during the day and 12-15°C at night. Zucchini thermophilia, hi light, should be early to pull the grass and grasshoppers, as far as possible to see more light plants.

3. After the roots of the plants are harvested and harvested, the vines are hung with plastic ropes, and lateral buds, tendrils and sick old leaves are promptly removed to facilitate ventilation and reduce nutrient consumption.

4, artificial pollination and hormone treatment as early as 6 to 9 male flowers, the anthers gently coated in female stigma, 1 male flower grant 2 to 3 female flowers. At about 10 o'clock, the stalks and stigmas were smeared with 20 to 30 microliters/liter of anti-drops.

5. About 50 days after harvesting and planting, the root melon can sit and live, weighing about 250 grams can be harvested and listed. After the size of about 500 grams of zucchini can be harvested and listed.

Viral Transportation Medium Tube

Uses: used for the detection and sampling of influenza, hand, mouth, foot and other epidemic diseases
Inspection principle:
The combination of multiple antibiotics has broad-spectrum antibacterial and antifungal effects;
As a protein stabilizer, bovine serum albumin can increase the survival time and infection stability of the virus;
Buffers such as Hank's build a neutral environment, which helps to increase the survival time and infection stability of the virus;
Phenol red is an acid-base indicator, the discoloration area is 6.6 (yellow)~8.0 (red), and it is red at 7.2~7.4.
Steps:
1. According to the sampling requirements, use a sampling swab to collect samples.
2. Place the swab after collecting the sample into a sterile sampling tube.
3. Break the sampling swab rod that is higher than the sterile sampling tube.
4. Tighten the cap of the sterile sampling tube.
5. Label the sterile sampling tube with information as required.

For sample collection, transportation and storage.
Product advantages:
1. The virus discretion of the flocking swab is high to ensure the accuracy of the test results.
2. The samples are well sealed to ensure product transportation and safe storage.
3. Product instruction manual, product certificate
Product Details:
1. The product set includes a one-time Virus Sampling Tube (including preservation solution), a self-sealing bag, a sampling swab, and instructions.
2. Product specification: 100 sets/box, 8 boxes/box 3. Product weight: 0. 65kg/box, 13. 2kg/box
4. Packing size: 25. 5*23. 5*14. 5 boxes, 53*49*32/carton
Scope of application:
Work resumption testing, the best choice for large-scale population screening
Features:
1. Transport at room temperature, stably preserve viral RNA
2. Pre-packaged guanidine salt lysate can inactivate the new coronavirus, ensuring the safety of transportation and testing personnel 3. The large-capacity preservation solution can fully soak the swab head,
The sample size can be divided into three parts for testing and reserve samples respectively to meet the testing needs.
Scope of application:
Suspected cases, disease control testing, preferred by P3 laboratory
