Abstract:

In order to perfect the cultivation technique of the new variety Shannong 38 for large-scale promotion.The experiment set a total of 15 processes that including 5 basic seedlings and 3 row spacing.This study analysed effects of yield,photosynthetic index and light use efficiency on wheat.The results showed that: the basic seedling treatment had great influence on each index,the difference was significant,the row spacing was next.The yield of 225×104 plants/ha basic seedlings and 23 cm row spacing was reasonable and high yield was obtained.In the same period,the population photosynthetic rate increased with the increase of basic seedlings and row spacing,and decreased gradually with the increase of basic seedlings and row spacing.GS was consistent with transpiration rate,and contrary to intercellular CO2 concentration.That with the growth period showed a first increase and then a decrease trend,with the increase of the basic seedlings gradually increased.Fv/Fm decreased significantly only in high density treatment of B5,and other treatments had no significant difference.The effective radiation amount and the interception rate of light radiation increased with the increase of basic seedlings and decreased with the increase of row spacing,there was no significant difference in effective radiation quantity and light interception rate under high density treatment,and no significant difference in row spacing treatment under high density treatment.
