Choosing healthy, mature, disease-free and insect-free branches for cutting(plastic nursery pots), the temperature required to control the growth of keel flowers is between 22 and 26 ° C, and the duration of illumination is guaranteed for more than four hours per day. The requirements for the soil are not very strict. If the keel flower is longer, we can choose the slightly acidic humus sandy soil with loose soil(15 cell propagation trays wholesale), sufficient nutrients and drainage. Conducive to plant survival.(plastic 7 gallon nursery pots bulk in canada)
Firstly, avoid the phenomenon of plant wilting during the breeding process(plastic nursery pots wholesale). When the temperature is lower than 5 °C, the cutting should also be stopped to avoid frostbite of the seedlings. After the preparation is done in the early stage, how to breed the keel flower, first we choose the healthy and mature mother plant as the selection object, cut the branches with good development around 5 cm at the top(21 cell propagation trays wholesale), soak the branch incision with root water, wait for five hours, you can put it into the soil for breeding.
(plastic 7 gallon nursery pots bulk in canada)Generally, they should be moved to a cool place or a light place for maintenance(black plastic nursery pots). In winter, the light is weak and can be completely placed outside for maintenance. The most suitable temperature for keel flower growth is between 22 and 26 ° C. It is like to grow in a humid and humid environment(32 cell propagation trays wholesale). In the hot summer, we should always spray the surface of the plant with a water spray nozzle to keep it moist and place it in ventilation. The place.
The keel flower is a survivable plant. Remember to expose the plants to avoid wilting(plug trays wholesale). Add 800kg of water, and the seedling fertilizer can be combined with watering. Then, 10 kg of ammonium sulphate can be traced, and the whole land can be ploughed, finely smashed, and the bottom fertilizer can be applied(50 cell propagation trays wholesale). The early application of topdressing is likely to cause the stalks of the above-ground leaves to grow and affect the bulbs. Or nitrogen fertilizer 40 ~ 50kg.
5 to 6 days after planting, the application of fully decomposed farm organic fertilizer 600 ~ 800kg(plastic nursery pots manufacturers), or ammonium sulfate 10kg, water 800kg, phosphorus pentoxide 60 ~ 80kg, evenly spread. If the soil is too acidic, apply appropriate amount of grass ash 400-500kg to adjust soil performance and facilitate onion growth(72 cell propagation trays wholesale). After the seedlings are slowed down, in order to promote the growth of stems and leaves and vegetative organs, appropriate amount of topdressing should be applied at the right time.
(plastic 7 gallon nursery pots bulk in canada)Stem and leaf expansion period is a key period to determine the onion yield(wholesale nursery pots), so it is necessary to topdress and fertilize in time. At this stage, the fertilizer is generally applied 2 to 3 times. However, it can be applied with 10 kg of ammonium sulfate, 5 kg of potassium sulfate, 800 kg of water, or 800 kg of fully decomposed 50% human excrement, combined with cultivating and weeding(98 cell propagation trays wholesale). It is necessary to pay attention to the best time to master the topdressing.
The base fertilizer should be applied evenly to prevent the partial application, less application and leakage(20 gallon nursery pots wholesale). Micronutrient also plays a vital role in onion production. Phosphorus deficiency will result in few dwarf leaflets and poor growth; in the absence of potassium, leaf veins are prone to dead spots; boron deficiency is easy to cause leaf chlorosis and deformity(105 cell propagation trays wholesale); calcium deficiency is prone to bulbous heart rot; magnesium deficiency is prone to muscle rot and root rot.
