Defeated wait plays an important role.Phosphorus can promote germination, contribute to bud differentiation, promote to bloom good, and maturation is promoted to carry
It is early solid；Root system development is may additionally facilitate, root system early growth and quick tiller is made.Paddy growth initial stage needs to absorb suitable phosphorus, because of rice
Incipient cell quantity sharply increases, if can absorb suitable phosphorus at this time, can promote tiller, elongation.If rice growth
Initial stage lacks phosphorus, and the cell growth of growing point is obstructed, and plant strain growth is slow, and individual is short and small, and cauline leaf is narrow thin, blade straight elevator, Cong Dingqi
It is flat, it is in tufted, i.e., so-called " common anotis herb " plant type, the few even nothing of tiller；Leaf color deepens, and is in dirty-green, celadon or dusty blue；Always
There is the irregular spot of bronzing in leaf, or brown streak occurs along vein, forms red withered disease.Also easily cause flax leaf spot；
Heading, delay of maturation, the underproduction are serious.
Zinc be in one of indispensable trace element of rice normal growth and development institute and soil general lack of one kind
Trace element.Rice normal growth needs to absorb the nutrients such as zinc, if paddy soil zinc-deficiency, the life of rice from soil
Length is necessarily suppressed, and rice plant is short and small, and Newborn Leaves are slow-growing, the base portion or middle arteries area chlorosis of lobus cardiacus, and upper blade becomes
It is narrow and thin, some appearance gauffers, middle and lower part blade be in sepia, new root is few, make rice strain growth it is irregular, heading evening and
It is few.Therefore, if zinc nutrition element cannot be replenished in time on the soil of zinc-deficiency, the yield and quality of rice can be seriously affected.
Magnesium is the indispensable element of nutrient necessary to rice and all green plantss institute, because magnesium participates in leaf
The composition of green element, is present in the center of chlorophyll molecule, and magnesium plays an important role to photosynthesis.When plant magnesium deficiency, chlorophyll and B
Carotenoid content decline, blade move back it is green, to CO2Assimilative capacicy decline, photosynthetic capacity reduce.Magnesium is in carbohydrate
It plays an important role in metabolism, magnesium can promote the activation of phosphate ester, glucose 1-phosphate1- invertase, be conducive to turning for monosaccharide
Change, magnesium can also promote vitamin A, ascorbic formation, and in enzyme system, magnesium can promote the activity of enzyme, especially enzyme and phosphoric acid
The transfer of salt is relevant.Magnesium also participates in protein synthesis.When magnesium deficiency, it will influence ribosomal normal configuration and make protein
Synthesis capability reduces.The symptom of rice magnesium deficiency：Diseased plant middle and lower part yellowing leaf, vein green, the division is clearly demarcated for mesophyll and vein, lacks
When magnesium is serious, inferior leaf, which is often rolled at pulvinus, to hang down, the face of getting wet of collapsing, the micro- volume of leaf margin；Cladus metulae portion flat-kernel seed increases, and causes to subtract
Production.Rice occurs " yellows " because of magnesium deficiency.
