Background technology
Phosphorus is one of macronutrient necessary to crop growth.It is to form Nuclear extract, lecithin etc. no
The element that can lack.P elements can accelerate cell division, promote root system and overground part to accelerate growth, promote bud differentiation, ahead of time
Maturation, improves fruit quality.The decomposition of respiration, photosynthesis, sugar and transport for example to crop etc. play important work
With.Phosphorus can promote germination, contribute to bud differentiation, promote to bloom well, and promote ripe solid ahead of time；May additionally facilitate root
System's development, makes root system early growth and quick tiller；Phosphorus can influence the normal growth of crop, bloom when lacking, and flower is diminished, and petal is reduced,
Pattern is bad；And making that branch is short, leaf is small, germinating power weakens, and the obfuscation of lower blade leaf color is in aubergine.
Calcium is one of middle amount nutrient necessary to crop growth.Calcium has in the formation and holding of fruit quality
Play an important role, particularly in the fruit development later stage, the formation of how many pairs of fruit qualities of calcium content of fruit and the storage after adopting
There is material impact with transport.Perhaps fructuous disorder symptom such as apple bitter pit, cherry dehiscent fruit, the softening of peach, pear
Black heart etc. all has substantial connection with calcium deficiency.Calcium is not only a kind of a great number of elements necessary to growth and development of fruit tree, prior
It is the regulation and control that fruit tree growth and development are participated in as the second messenger of extracellular signal and intracellular biochemical reactions.Ca2+- CaM joins
With regulation differentiation of floral bud of fruit tree, pollen germination, fruit maturation and degeneration-resistant expression etc..
Calcium is one of most abundant element of content in soil, and fruit tree calcium deficiency is also not meant to soil hypocalcia, even if
Growing plants still has the situation that physiological disease occurs on calacareous soil rich in calcium.Plant calcium deficiency is caused to be primarily due to calcium
It is again not easily shifted after being difficult to be absorbed by plants and absorb, cause substantial amounts of calcium to be present in leaf, it is very few in fruit.Calcium can only be unidirectional
Up shift, and influenceed by transpiration, the phenomenon that the calcium in low-transpiration fruit flows backwards to branches and leaves, thus fruit can usually occur
It is real easily to show calcium deficiency symptom.Fruit losses in cultivation of fruit tree only as caused by calcium deficiency account for yield 20%~
30%.Therefore, the more crops of calcium (such as banana, oranges and tangerines) easily calcium deficiency is needed, it is necessary to apply External Calcium, and it is maximally effective
Method is by foliage-spray through blade and fruit surface, so as to shorten calcium constituent displacement.
Calcium and phosphorus are all the essential nutrient elements of growth and development of plants.Therefore, phosphate fertilizer and calcareous fertilisers are matched somebody with somebody in agricultural production
The synthos of indissoluble are easily formed during it is inevitable that conjunction is applied, but phosphate fertilizer is manured into soil with calcareous fertilisers, so as to have impact on calcium
