A Study Of Effect Of Applying Nitrogenous And Phosphate Fertilizer On Yield And Quality Of Longdan 24 Corn

In order to investigate effects on yield and quality of corn, Longdan 24, applying(?)itrogenous and phosphate fertilizer to corn, the experiment uses such a method as fieldest, which is set up 4 standards, N80kg/hm² for N₁, N120kg/hm² for N₂, N160kg/hm² forN₃, based on applying the same amount of potash fertilizer. It is set up 3 standards ofpplying phosphate fertilizer, which are P₂O₅35kg/hm² for P₁, P₂O₅70kg/hm² for P₂ and(?)₂O₅105kg/hm² for P₃. The test is set up 12 kinds of operation, used by a stochasticgrouping design and repeated three times. The following data is analyzed, plant height,(?)erimeter, height of ear, length of ear, perimeter of ear, grain lines of ear, grains of ear,Neight of 100 grains, grain weight of ear, yield and crude protein, crude fat, crude starch(?)nd lysine.The test result shows that it leads to affect significantly corn height, perimeter and(?)eight of ear if applying nitrogenous and phosphate fertilizer to corn. A significant(?)ifference comes into being to corn height if different types of test operation are done, ofNhich N₃P₂ achieves a maximum, N₃P₂, N₄P₁, N₃P₃ and N₃P₁ achieves a significantfifference to perimeter of corn, N₃P₂ a maximum, N₁P₃ minimum, difference value being0.48cm. A significant difference comes into being to height of ear among types of(?)peration, of which N₃P₃ achives maxirnum, N₂P₁ achieves minimum. It providesmportant conditions to lodging resistance of corn if proper corn height, height of ear andtem perimeter being achieved.The factors of yield show, if applying nitrogenous and phosphate fertilizer to corn,N₃P₃ achieves a maximum, 22.7cm, to length of ear, achieve a most significant differenceo compare with others. The difference of ear perimeter also achieves a significant(?)ifference among them, of which N₃P₂ achieves a maximum, N₁P₂ a minimum, differencealue being 1.0cm. N₃P₁ achieves the most to grain lines of ear. N₃P₁ N₃P₂ and N₃P₃chieve a significant difference to compare with other types of operation, of which there is##原图像不清晰 no significant effect on grain lines of ear to apply phosphate fertilizer to-corn or not. N₃P₃achieves the most grains of ear, being a significant difference to compare with other typesof operation. N₁P₂ makes weight of 100 grains a maximum, and N₁P₂, N₃P₃ achieves aobvious difference to compare with other types of operation. N₃P₂ makes grain weight ofear a maximum, being a significant difference to compare with types of operation. Theyield result shows that N₃P₂ achieves a maximum to compare with other types ofoperation.It significantly affects on quality of corn to apply nitrogenous and phosphate fertilizerto corn. N₂P₃, N₂P₁ and N₂P₂ make crude protein of corn a high numerical value, being asignificant difference to compare with other types of operation. There is no obvious effectno crude protein to apply phosphate fertilizer or not. N₃P₃ makes crude fat and crude starcha maximum, being a significant difference to compare with other types of operation. N₂P₃,N₂P₂ and N₂P₁ make lysine a high numerical value, being a significant difference tocompare with other types of operation.The experiment shows that N₃P₂ makes yield of corn, Longdan 24, a maximum, and itsquality is better, being the better operation of fertilizer application.
