Jimai 22

The variety is winter. the seedlings are semi-erect. The cold resistance is good, the tillering is strong, and the panicle rate is high. It belongs to multi-spike type variety. Compact plant type, small leaves, upward thrust, more wax in stems and leaves, plant height 70~75cm, good stem elasticity, strong lodging resistance and good comprehensive disease resistance. Luohuangjia, panicle rectangular, long awn, white shell. White grain, horny. The seeds are full. Determination of mixed samples in Shandong regional test in 2003. Bulk density 771g/L. The yield components of 667m2 were 450000 ~ 550000 panicles and 35.65 grains per spike. The weight of 1000 seeds is 45g. Its outstanding characteristics are high yield potential, wide adaptability and strong stress resistance. It is suitable for planting in the medium-high fertilizer and water plot of Shandong province. 2 Super high-yield cultivation techniques 2.1 increase the application of organic fertilizer, balanced application of chemical fertilizer, improve soil fertility and fertility according to Henan @ 245 fertilizer @ high and stable high and low cooperation group. The dependence rates of soil nitrogen, phosphorus and potassium nutrients on super-high-yield wheat produced by 667m2 above 600kg were 82.8%-85.9%, 91.7%-95.1% and 85.1%-88.3%, respectively. The dependence rate of soil nitrogen, phosphorus and potassium nutrients (between 65% and 80%) in high-yield wheat fields with 500kg production by 667m2 was much higher, indicating that the realization of super-high yield wheat should be guaranteed by fertile soil.
