Phosphorus can promote the tomato flower bud, early flowering, promote seedling root growth and improve fruit quality. Phosphorus deficiency, the young shoot and root growth and slow, and plants stunted, leaves are dark green, dull, purple back.
The absorption of phosphorus in tomato plants during early growth was higher in the first spike of fruit grow to walnut size, plant P uptake about 90% of the whole growth period. Therefore, the tomato seedlings can not be P-deficient, so as not to affect the flower bud differentiation. Tomato phosphate absorption capacity of weak, especially in the low temperature absorption was low. Phosphate in general as basic fertilizer, and 0.5% potassium dihydrogen phosphate solution can also be used as foliar spray, for foliage spray. Potassium in plants for amino acids, protein and carbohydrate synthesis and transport of the delayed plant senescence, extend the results period, to increase the latter part of output have a good effect.
