2. Phosphorus deficiency In the early stage of crop growth, the role of phosphate fertilizer is not obvious, but in the middle and late stages, phosphorus deficiency will affect the effective accumulation of nitrogen and protein synthesis. Phosphorus deficiency in different crops has different symptoms. Such as:
(1) The performance of phosphorus deficiency in wheat is: the seedling grows slowly, the root system is poorly developed, the tiller is reduced, the base of the stem is purple, the leaf color is dark green, slightly purple, the ear small particles are small, and the 1000-grain weight is significantly reduced.
(2) The performance of phosphorus deficiency in maize is: slow growth at seedling stage, obvious symptoms at the 5th leaf stage, purple-red leaves, short and small corn cobs, curved shape, premature baldness, and most of the seeds are not full.
3. Potassium deficiency (1) The tip of the lower part of the general crop turns yellow, gradually yellowing along the edge of the leaf, and the veins on both sides and the midrib are still green. In severe cases, most of the leaves are yellow and the edges of the leaves are burnt.
(2) Cereal crops show weaker tillering power, soft stems and easy lodging.
(3) The leaves of dicotyledons are curled, gradually shrinking, and sometimes the leaves are broken, but the middle part of the leaves remains green.
(4) The quality of the root crop is reduced and the quality is poor.
(5) The fruit ripening period is inconsistent, the pulp is increased in wood, the taste is sour and not delicious.
