Spring cantaloupe cultivation techniques

In the spring, the cost of open cultivation of melons in open fields is low, and it is easy to manage. It is a best choice for farmers to increase their wealth in the short term.

1, soaking

After selecting good varieties, they can be properly sun-dried in good weather and then screened. Warm soaking can be soaked in water at 55°C for 1 minute and then cooled to 25°C. After 6 hours, remove it and let it dry. Then, germinate at a temperature of 28°C.

2, nursery

65-hole black seedling trays can be used to raise the seedlings (the average temperature is above 15 degrees) and the seedling age is about 35 days. To 3 to 5 leaf stage seedlings can be planted in Daejeon.

3, colonization

Transplanting in mid-May, the planting density can be selected according to the variety. After transplanting, pay attention to water management, shorten the period of seedlings as much as possible, and pour the water into the seedlings to keep the ground temperature and supply sufficient water for seedlings. Cover the film to moisturize and increase the temperature. Water-retaining agent can also be used during transplanting, which can reduce the number of watering and can be poured once more during the whole growth period.

4, fertilization

The basal fertilization is applied once, and the ditch is established at a distance of 30 cm from the plant, and 50-100 kg of potassium sulfate compound fertilizer is applied per mu, or 2-3 parts of the decomposed livestock and poultry manure. Or ternary bio-organic fertilizer 50-100 kg, in the middle and late foliar spraying potassium dihydrogen phosphate, harvest No. 1 and other supplementary adjustments, but also balanced vegetative growth and reproductive growth, improve the fruit setting rate.

5, medication

With the application of 2-4 kg net or phoxim or avermectin per acre to spread fertiliser, it is necessary to prevent and control underground pests, nematode diseases, or soil-borne diseases; the prevention of virus diseases should be strengthened during plant management. About every 10 days, the leaves were sprayed with phytosanitary and protective fungicides once.

6, watering

Usually less watering, seize the key period such as expansion of melon water, at the same time to chase application of quick-release compound fertilizer, to ensure that melons have adequate nutrients, timely watering drought.

7, management

Due to the variety characteristics of the selection of appropriate pruning vines, such as Xiangmi 900 pruning does not have to be pruned, allowing it to grow naturally; while the White Series melons need five vine pruning to stay 3 to 4 melons.

8, taboo

Most melons are bogey, boiled when soil heat, boiled chlorine fertilizers, bogey flowering, bogey nitrogen fertilizer, bogey rape planting, avoid planting under the big trees. Look to the melon friends for attention and reference to planting to ensure a good harvest.

Influenza Vaccine

Influenza Vaccine, Live, Nasal, Freeze-dried Exclusively authorized by the WHO in China WHO
Influenza Vaccine, Live, Nasal, Freeze-dried is a cooperative project with the WHO, which has been included in Global Action Plan for Influenza Vaccines (GAP)[1]. Hundreds of millions of doses have been used in the world, and Changchun BCHT Biotechnology Co. has the exclusive right of production and

operation in China.

Intranasal spray administration, no injection and no pain


The vaccine is inoculated by nasal spray, equipped with nasal spray device, and only needs to spray once a year in two nostrils to prevent influenza.
Mucosal immunity + Cellular immunity + Humoral immunity

After influenza virus attacks human body, it widely exists in nasal cavity, respiratory tract and other mucosal parts, as well as in body fluids and cells.
Vaccination of Influenza Vaccine, Live, Nasal, Freeze-dried can quickly stimulate the triple immune response of human body, and carry out defense
against viruses in different parts:
·Intranasal administration can produce mucosal immunity (IgA antibody), which forms the first immune defense line in the nasal cavity.
·Produce humoral immunity (IgG antibody) to remove influenza virus from body fluids.
·Produce cellular immunity (T cells) to remove influenza virus from cells
3+N More extensive protection
The production strains are recommended and supplied by the WHO every year.
The vaccine can not only effectively resist the vaccine strain, but also produce cross immunity to other subtypes of influenza virus.

Produced with SPF embryonated eggs


The chick embryos for vaccine production comes from SPF (specific pathogen free) chicken flocks, so the risk of exogenous pathogenic microorganism

pollution is excluded.


Free of inactivator, split agent and preservative

High protection and fast antibody production

This is the first influenza vaccine in China that has been evaluated by the protection effect of etiology in clinical stage. The protective effect of phase III
clinical trial is consistent with the literature[2] .
First, the immune barrier was formed in the nasal mucosa after LAIV vaccination. It has been reported that the antibody of nasal mucosa can be
produced in 3 days[3], which greatly shortens the time for vaccine to produce
protective effect.
