After 2 years of multiple asexual propagation (cutting propagation), the plant population has stable consistent characters in the main performance, and EF68 wheat has high yield, stability, adaptability and better adaptability. The yield per mu in the experiments from 2013 to 2014 is 760.6 kg, and the yield is increased by 35 percent compared with Yumai No. 2. The yield per mu of 785.5 kilograms in a one-2016 year product comparison test in 2015 is increased by 36.6 percent compared with that of a control Xiaozhi 54, and the yield increase reaches extremely remarkable two years. The composite straw has the advantages of better comprehensiveness, lodging resistance, cold resistance, strong growth vigor, thick and strong stems, toughness, large ears, good yield, better powdery mildew resistance in comparison with the standard ratio, good appearance quality, high flour yield and later-stage dry hot air resistance.
The suitable seeding time is in the middle ten days of 10 months, and the suitable seeding is as follows: in Anhui, hebei, henan and Shandong areas, farmyard manure is required to be additionally applied as a base fertilizer according to different soil fertility, reasonable close planting is carried out, and the using amount is about 10 kilograms. Scientific management, adequate base fertilizer, attention to the matching of field ditches and lines, prevention of light waterlogging and dark stain, application of about 15 kg of pure nitrogen per mu, wherein 70 percent of the pure nitrogen is used as a basic seedling fertilizer, 30 percent of the pure nitrogen is used as a jointing and booting fertilizer, and the application of phosphorus-potassium fertilizer is matched, so that the diseases, the pests and the weeds can be prevented and controlled in time, the crops can be harvested in time, and the high yield and the high harvest can be ensured. The cultivation of EF68 wheat varieties greatly improves the yield per unit of wheat and increases the total yield, high-yield wheat has large demand and high total yield as the national wheat planting area, and the cultivation and large-area cultivation of EF68 wheat has important significance for further improving the comprehensive productivity of wheat and ensuring the grain safety.
In the middle stage of grouting, cheng Kui EF68 and Yumai No. 2 are respectively taken to test the content of the flag leaf wax.
Cutting wheat leaves into small leaf segments of 5 cm, placing the small leaf segments in 30ml of chloroform, and soaking for 30s; then, the solution was filtered through filter paper into an evaporation dish of known weight (W1), placed in a fume hood, and weighed again after the chloroform was completely volatilized (W2); the difference between the two weights is the weight of wax; each treatment was repeated 5 times. The wax content was calculated as fresh leaf weight (W3) units. Cheng Kui EF68 flag leaf wax content is 16.42mg/g on average, and is 69.4% higher than Yumai No. 2 variety on average.
