| Abstract: |
| With two new fostered wheat strains as materials, determination and comparison were made of their physical and biological characters to study the influence of different sowing quantity and row spacing on physical and biological properties of different wheat varieties in different local donditions. The results show that, in 4.5 million seeding quantity and 16.7 cm row spa
ce of planting configuration model, the canopy temperature, the flag leaf chlorophyll content, the penultimate leaf chlorophyll content and the number of ears per acre are all better than other cultivation models. |
