THE RELATIONSHIP OF GROWTH AND TEMPERATURE OF PEANUT
The active accumulated temperature of peanut needs to be greater than 15 ℃ from flowering to first full fruit, the annual accumulated temperature of early maturing varieties needs to be I45090, the annual accumulated temperature of medium maturing varieties needs to be 155090, and the annual accumulated temperature of late maturing varieties needs to be 164090.
The research shows that the activity accumulated temperature of peanut needs to be greater than 15 ℃ from flowering to the first full fruit, the annual accumulated temperature of early maturing varieties needs to be I45090, the annual accumulated temperature of medium maturing varieties needs to be 155090, and the annual accumulated temperature of late maturing varieties needs to be 164090. In a certain range of high temperature (30 a 3790) conditions, the effective filling period of British fruit is short (I. e. mature fast), the number of fruit per unit area is small, the average fruit weight is low; when the temperature is moderate (23 a 279C), the filling period of British fruit is long, the number of fruit per unit area is large, the average fruit weight is high. Above 35 ℃, the development of peanut is inhibited, below 15.5 ℃, the basic does not grow, when the temperature is below 19 ℃, can not form the needle. It shows that if there is enough growth period, the average temperature is moderate, which is beneficial to the increase of pod yield and the increase of full fruit rate. The results showed that there was a high correlation between the satiety rate and the sensory quality and biochemical quality (such as oil content, protein content, oleic acid/linoleic acid value, etc.) of peanut. Therefore, the quality of peanut depends on the maturity of English fruit to a great extent. The temperature change directly affects the ripening of English fruit and the size of the full fruit rate.
