| Abstract: | The aim is to study the effect of intermission seeding under millet and peanut intercropping on millet agronomic traits and yield. The millet variety ‘Jinxuan 6’ was used as material, 6 seeding dates of millet (T1: May 15, T2: May 20, T3: May 25, T4: May 30, T5: June 4 and T6: June 9) were set up, and the seeding date of peanut was May 15. Then the agronomic traits, yield factors and yield of millet were explored in different treatments, and the yield and intercropping productivity under the millet and peanut intercropping mode were studied. The results showed that with the postponing of millet sowing date, the height, ear weight, ear length and grain weight of millet decreased first and then increased, while the stalk thickness, dry weight and ear formation rate of millet presented a decreasing trend. Under intercropping, there was a significantly positive correlation between millet yield and ear length (0.911 *). At the same time, the later the sowing date of millet, the greater the impact of peanut on millet, which could affect the ear length and the grain weight per spike of millet and was not good for millet yield formation. The land equivalence ratio (LER) of the intercropping mode increased first and then decreased with the postponing of the sowing date, and the LER of T4 reached the maximum, and then decreased, the LER was less than 1 at T6, showing the disadvantages of intercropping. Therefore, under the condition of this experiment, at T4 (when sowing date of millet was 10 days later than the sowing date of peanut), the comprehensive yield of millet and peanut intercropping could reach the maximum and the yield of millet was relatively high. |
