In whole vital processes of crop, boron plays crucial effect.It has irreplaceable single-minded physiological function, participates in many important physical activities, and strengthens many important physiological functions of crop.Boron is in liberal supply, and plant growth is in great numbers, full grains, and root system is good, and it is guaranteed to have a good harvest, on the contrary boron is under-supply, and plant strain growth is bad, and the quality of product and output descend; During serious boron deficiency, can cause that No kernels or seeds are gathered, as in a year of scarcity.
Boron is participated in the moity of crop each several part.Boron can promote amino acid and proteinic synthetic, and promotes the conversion and the running of glucide, accelerates crop growth, and is short precocious.Boron has good action to chlorophyllous formation and stability.During boron deficiency, yellowish-whiteization of young leaves, Lao Ye flavescence.Boron can suppress the formation of phenolic cpd in harmful fruit, prevents terminal bud brown rot, heartrot.Boron can promote pollen germination, stimulates pollen tube growth, and the plant insemination is had special great influence, is beneficial to fruit, seed formation.
Magnesium is chlorophyllous central atom, is the moity of chloroplast(id), or the component of some enzymes and acvator, can regulate proteinic synthetic.
Magnesium is active elements, and movability is fine in plant, and 70% of full magnesium amount is movably in the plant tissue.So general magnesium deficiency symptom at first appears on the old and feeble blade of low level.The utilising efficiency again of magnesium is higher in the plant body in addition, so the magnesium deficiency element all occurs in the fertility middle and later periods mostly, especially forms the back with seed and sees more.Common symptoms is bottom leaf mesophyll chlorisis flavescence, but vein still is green.Further develop, whole blade is organized all yellowish, and browning is until final necrosis then.
The crop responsive to magnesium deficiency mainly contains rape, yam, banana, oranges and tangerines, sponge gourd, corn, secondly is cotton, barley, wheat, paddy rice and wild cabbage and grape, peach, apple etc.Also easy magnesium deficiency such as tobacco, Cauliflower, Sunflower Receptacle, jerusalem artichoke, pineapple, persimmon, herbage.
Potassium element can improve the osmotic pressure of enchylema, keeps the elasticity of cell walls, can reduce the loss of moisture.When potassium element is sufficient; The mechanical resistance that vegetable cell wall thickening, tough and tensile, the anti-bacterial parasite of stem stalk penetrate increases, and the intravital low molecular compound of crop reduces simultaneously, and pathogenic bacteria lacks food source; Just stoped development of disease, so potassium is clearly in the effect aspect the enhancing crop disease resistance.
Potassium can promote photosynthesis, improves photosynthetic efficiency, promotes the transportation of photosynthate.When potassium element was sufficient, monose carried out to sucrose, the synthetic aspect of starch, so potassium has desirable influence to starch based, sugar crops yield and quality.Potassium can also promote absorption and the utilization of crop to nitrogen, promotes proteinic synthetic.Therefore, potassium is in liberal supply, not only increases output, can also increase Protein content in the seed, improves quality.Except the raising that shows basic nutrition material (like protein, glucide etc.), also can increase content of mineral substances, improve the mode of appearance of fruit and the storage endurance property of increase fruit etc.
