In the early stage of melon growth, the leaves showed a slight yellowing, followed by leaf margins in the order, followed by yellowing between the veins, and the order was obvious; at the middle and late stages of reproduction, the same symptoms as those described above occurred in the middle leaves; The limbs died of dead, with the leaves growing continuously, the leaves curled to the outside; the symptoms among the varieties varied significantly.
Pay attention to the location of the symptoms of the leaves. If the symptoms appear in the lower leaves and the middle leaves may be potassium deficiency; at the early stage of birth, when the temperature is low and the cultivation is covered (double cover), the gas damages have similar symptoms; the same symptoms, if present In the upper lobe, it may be calcium deficiency. The deficiency of potassium in the early stage of growth is relatively rare. It occurs only when the potassium is extremely low. Careful observation of the initial symptoms, the potassium margin is mostly potassium deficiency, and the leaf margin remains green. Might be magnesium deficiency.
Apply sufficient potassium fertilizer, especially in the middle and late fertility period, pay attention to potassium deficiency; melon plants have an average of 7 grams of potassium per plant, which is basically the same as the amount of nitrogen absorbed. This should be taken into account when determining the amount of fertilizer to be used; Composting and other organic fertilizers; if potassium is insufficient, potassium sulfate can be used on average 3 to 4.5 kg per mu, once topdressing.
Removable Oxygen Generator
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
