Study On Colony Characteristic Among Different Emergence Ability Wheat Variety By Density And Fertilizer Control

The study on the colony characteristic among the 4 factors of cultivating measurements on five different emergence ability wheat variety by applying the design of perpendicularity rotational combination.The results get the main effective factors of wheat colony growing and parse those group targets include the time limit of groups completion,the limit of groups,volume of effective ear,volume of individual turn to ear.By contrasted yield and quality of those different emergence ability varieties,we established some scheme of planting as flows.1,The first varieties emergence lately which is QianMai15,the time is longly when it reach the the limit of groups,and the rate of spike is high.The affecting of pilot factors are basic seedling＞N＞P₂O₅＞K₂O.The scheme of planting include: fundamental seeding 93.81 to 143.71 kg/ba,N-fertilizer fertilizer 213.2 to 255.89 kg/hm²,P-fertilizer 522.04 to 774.26 kg/ha,K—fertilizer 82.94 to 150.32 kg/ha.2,The second type varieties emergence earlier which is QianMai16,the time is shortly when it reach the the limit of groups,and the rate of spike is moderate.The influence of pilot factors is basic seedling＞N＞P₂O₅＞K₂O.The scheme of planting include: fundamental seeding 93.81 to 143.71 kg/ha,N-fertilizer 213.20 to 255.89kg/ha, P-fertilizer 522.04 to 774.26 kg/ha,K—fertilizer 82.94 to 150.32 kg/ha.3,The third type varieties emergence lately which is CaoXuan5,the time is shortly when it reach the the limit of groups,and the rate of spike is very lowly because of a large number emergence dead in earing stage,so it's spike depend on the caulis. The affecting of pilot factors is basic seedling＞N=P₂O₅＞K₂O.The scheme of planting include:fundamental seeding 93.81 to 143.71 kg/ha,N-fertilizer 213.2 to 255.89 kg/ha,P-fertilizer 522.04 to 774.26 kg/ha,K—fertilizer 82.94 to 150.32 kg/ha.4,The fourthly varieties emergence earlier which is ZaoMai16,the time is longly when it reach the limit of groups,and the rate of spike is high.the affecting of pilot factors are basic seedling＞N＞P₂O₅＞K₂O.The scheme of planting includes:fundamental seeding 65.78 to 74.27 kg/ha,N-fertilizer 163.54 to 187.05 kg/ha,P-fertilizer 768.95 to 842.93 kg/ha,K—fertilizer 196.84 to 222.71 kg/ha.5,the fifths varieties emergence earlyierly which is 0310,the time is longly when it reach the the limit of groups,and the rate of spike is very lowly because of a large number emergence dead in earing stage,so its spike depend on the caulis, the affecting of pilot factors is basic seedling＞N＞K₂O＞P₂O₅.The scheme of planting include:fundamental seeding58.29 to 66.83kg/ha,N-fertilizer 180.28 to 278.61 kg/ha, P-fertilizer 676.24 to 1107.01 kg/ha,K—fertilizer 124.67 to 229.41 kg/ha.
