Analysis of plant characteristics and yield
The plant traits of different peanut growth and development are the main factors influencing the harvesting efficiency and effect when the machine harvests. From the data in Table 1, it can be seen that the plant traits and yield of each peanut variety vary widely, with the greatest range among varieties for shell hardness, followed by plant height. The yield of different peanut varieties is greatly different, and the difference reaches 6596.85 kg per hectare.
TABLE 1 mean values and variation of plant traits and yields for different peanut varieties
Correlation analysis of different traits of peanut varieties
As can be seen from Table 2 and Table 2, the fruit burying rate at the time of mechanical harvesting is inversely related to the stalk strength of the peanuts at the time of digging, and is significantly and positively related to the fruit depth and the fruit pin length. The larger the stalk strength of the peanuts in the digging process is, the smaller the fruiting depth and the length of the peanut needles are, and the smaller the field fruit burying rate is. The fruit drop rate is negatively related to the stalk strength, the seedling stalk strength, the fruiting range and the fruiting depth when picking up and picking up fruits, and the peanut plants are too high, and the longer the lateral branches are, the more the peanut plants are not beneficial to mechanical picking up and picking up the fruits. The yield is mainly positively correlated with the stalk strength during digging, negatively correlated with the stalk strength during picking, and negatively correlated with the fruiting depth in soil and stalk length. The results show that the fruit stalks are tough during planting and digging, the results are concentrated, and the high-yield and high-quality peanut variety with no over-high plant can reduce the field loss caused by mechanical peanut harvesting. Wherein, the fruit stalks 1 are used for airing 1 day fruit stalks, the seedling stalks 1 are used for airing 1 day seedling stalks, the fruit stalks 7 are used for airing 7 day fruit stalks, and the seedling stalks 7 are used for airing 7 day seedling stalks; * And indicates significant differences at p <0.05 and p <0.01 levels, respectively.
