It is necessary to lightly apply seedling fertilizer, skillfully apply vine fertilizer(cheap plastic plant pots bulk), and reapply fruit fertilizer to supplement the deficiency of base fertilizer to meet the needs of watermelon growth and results. So how is the watermelon topdressing? What is the main point of watermelon topdressing(2 gallon plant container wholesale)? Promote seedling fertilizer is generally applied within one week after the transplanting of the melon seedlings or in the 4-5 leaf stage of the live seedlings.(cheap 5 gallon smart grow pots for sale)
However, generally 8 to 10 grams of urea per plant (or 20 grams of ammonium sulfate) is applied to the soil after ditching and fertilizing(nursery plant pots). Generally, when the melon seedling grows to 40-60 cm, 10-12 kg of urea per acre, 8 kg of superphosphate, 13 kg of potassium sulfate, or 18-22 kg of 45% potassium sulfate ternary compound fertilizer per acre(cheap 3 gallon plant pots). Do not look for nitrogen fertilizer and partial nitrogen fertilizer is easy to cause vine leaves to grow wild and difficult to sit.
It is applied at a distance of 25 to 30 cm from the root of the melon or between the two plants(plastic plant trays wholesale), and the depth of the groove is 10 to 15 cm.Do not pursue the application of chlorine-containing fertilizers, such as ammonium chloride or potassium chloride(4 gallon nursery pots wholesale). Due to the influence of chloride ions, the sugar content of watermelon will be reduced, and the taste of watermelon will become sour and the quality will be deteriorated. Urea and sulfuric acid should be used.
(cheap 5 gallon smart grow pots for sale)High-quality superphosphate 80 to 100 kg or potassium dihydrogen phosphate 30 kg(gallon pot), potassium sulfate 15 kg, chasing watermelon special fertilizer effect is better. Do not top dress in the drought when topdressing soil drought, the cytoplasmic aqueous solution of watermelon roots will leak out(1 gallon plant pots supplier), causing the separation of the root cell wall, which can easily cause the physiological loss of water from the watermelon vine leaves and wither or even die.
When the fertilizer of the base fertilizer is insufficient or the fertilizer effect of the base fertilizer has not been exerted(plastic plant pots wholesale suppliers), a small amount of quick-acting fertilizer is applied. When the soil is insufficiency, the top dressing should be carried out at the same time as the top dressing and watering or after first watering(1.5 gallon nursery pots wholesale). Nitrogen, phosphorus and potassium ternary turbidity should be applied in tandem to promote the steady growth of melons to improve quality.
Do not force the fertilizer even in rainy days(cell trays), the air humidity is high, not only will cause fertilizer loss, but also cause the watermelon vine leaves to grow long, the leaves are tender and crisp, and the watermelon resistance is weakened and it is easy to get sick. Don't be close to the seedlings. The roots of the watermelons spread with the spread of the vines(2 gallon plant pots supplier). The topdressing is too close to the seedlings. Not only the fertilizer is not fully absorbed, but it is easy to burn.
Calcium, magnesium, sulfur, silicon, zinc, iron, potassium and other elements are sprayed through the foliage(large plastic terracotta pots), which is fast and good for promoting the reproductive growth of strawberries and improving the fruiting degree of berries. Foliar fertilization is an important part of top dressing and is indispensable for strawberries in greenhouses(2 gallon plant pots wholesale). After the application, the soil is covered with water to promote the absorption of fertilizer.(cheap 5 gallon smart grow pots for sale)
It is advisable to topdress 30 cm from the eye of watermelon seedlings(square grow pots). According to the growth needs, the selection of foliar fertilizers such as potassium dihydrogen phosphate, anhydrous borax, magnesium sulfate, Escherichia calcium, Coronide copper, ferrous sulfate, etc. can significantly improve the quality of strawberries(1 gallon pots manufacturer). Potassium, potassium dihydrogen phosphate and other fertilizers. The following small series will give you a detailed introduction.
