Even if we choose some fungicides with strong internal absorption, how much more effective will they be when they reach the roots(plastic planter pots)? When the leek seedlings grow to 7-10CM, it is necessary to apply 20% concentration of human feces or biogas water once (i.e. 2 portions of rotten human feces and urine vs. 8 portions of clear water), about 15-20 days later(2 gallon nursery pots bulk), and then apply it once every other week, with the same concentration as last time.

When the leek seedling grows to 30-50cm, the concentration of human feces and urine (i.e. 3 parts of human feces and urine vs. 7 parts of clear water) should be applied(6 inch plastic plant pots), and 0.5% urea should be added to the fecal water. At the same time, in case of a long drought, it is necessary to put water into a ditch for irrigation(3 gallon nursery pots bulk). When the surface of the border is full of water, it is necessary to apply 50% of human feces and urine plus 0.5% urea.(cheap plastic starter pots manufacturers ireland)
If the seedling potential is weak, the leaves are thin(propagation trays australia), and the stem is not thick and hard enough, the organic compound fertilizer can be applied properly, with the dosage of 20-25kg per 667m2. Weeds in the field should be cleaned up in time, and they should be removed early and frequently to keep the border free of weeds(5 gallon nursery pots bulk). Soil cultivation is one of the main measures to soften the pseudostem, which is usually carried out in 2-3 times.
Today, let's take a look at the key points of leek fertilization(5.9inch plastic plant pots). Before each soil cultivation, 20-25kg / 667m2 organic compound fertilizer should be applied on both sides of the row of leek seedlings. When the false stem is 15-20cm long and the height of the seedling is about 50cm(plastic cell trays supplier), the first soil cultivation should be carried out to 2cm away from the loading mouth when the planting (i.e. transplanting by plants) or the first time of leek cutting is 4-5 months later.
(cheap plastic starter pots manufacturers ireland)After about 7 days, the second soil cultivation will be carried out. This time, it will be in line with Hekou(cheap small plant pots). If the first and second time is not well done, the third time is a little more than 1cm. The dosage is 1000-1500kg of human feces and urine water or biogas water or 100-150kg of granules per 667m2(cell seed trays). The above focuses on the persecution and prevention of the two root diseases of Atractylodes macrocephala at seedling stage.
When cultivating soil, the leaves of leek should be picked up and fixed with a thin bamboo pole first, and then cut off the leaves of leek more than 2cm away from the lotus mouth after the leaves are long(6.3inch plastic plant pots). After cutting green, apply 5% concentration of human feces and urine or biogas water for one time(plastic potting pots). If the spring rain is too much to chase human feces and urine or biogas water, use Dali brand organic compound fertilizer granules instead.
For example, in the spring seedling stage(6 inch plastic nursery pots), in the cold and rainy weather, we should be alert to the occurrence of the blight of Atractylodes macrocephala, especially when the temperature is above or below 24 ℃, which is more suitable for the occurrence of the blight(1 gallon nursery pots bulk). However, for the two root diseases of Atractylodes macrocephala, the reason why it is difficult to prevent and control is not only the resistance of the pathogen itself, but also the way of application.
We need to change the way of applying this kind of fungicides, but we need to adopt the method of root irrigation(6.5inch plastic plant pots), so that the liquid medicine can contact the infected parts of the roots indirectly, so that the sterilization and treatment are more indirect. The commonly used fungicides are: Copper humate, Jinggangmycin + Bacillus subtilis(seed starting trays wholesale), fumeishuang + oxamyl, captan + Bacillus subtilis Bacillus, metalaxyl + oxamyl, etc.(cheap plastic starter pots manufacturers ireland)
