Separating out saturated grains by a water separation mode, air-drying the rest part, then carrying out air separation by an air separator to obtain half-saturated grains and empty grains, weighing three parts of 30.0g of saturated grains and 2.0g of empty grains as small samples, manually counting the number of the solid grains and the empty grains, calculating the total number of the saturated grains and the empty grains, counting the total number of the small samples if the half-saturated grains are not taken, drying and weighing the grains, and calculating the number of flowers per spike, the setting rate and the thousand grain weight.
The results are shown in tables 1 to 3 below and fig. 1:
TABLE 1 actual sowing density and emergence under different sowing conditions of 1000 super-optimal seeds
Note: data are mean ± sd, and the same letters in the same column indicate no significant difference between the two, while different letters indicate that the two differ significantly at the 0.05 level.
Under different sowing modes, the theoretical sowing amount is consistent, and the actual sowing amount has no significant difference. However, the variation in the actual seeding rate during the investigation is large, and the variation in the actual seeding rate of the seeding belt is small at different investigation positions. In terms of average number of emergence and average rate of emergence, no significant difference exists between manual sowing and seed sowing, but the variation of the two indexes is large. The number of seedlings after sowing is less than that of other two sowing modes when the machine dibbles.
Table 2 tillering and spiking conditions of 1000 super-excellent under different planting conditions.
Note: data are mean ± sd, and the same letters in the same column indicate no significant difference between the two, while different letters indicate that the two differ significantly at the 0.05 level.
When the sowing belt is used, the tillering number of a single plant is obviously higher than that of a sowing treatment, the variation of the tillering number among different single plants is small, and under the sowing condition, the tillering condition of different individuals is large. In the whole view, the maximum tillering number per unit area under the sowing condition is higher than that of the sowing belt treatment, but the ear forming rate under the sowing belt treatment is higher, and the final effective ear number is obviously higher than that of the sowing treatment. The tillering number of the single plant treated by the mechanical dibbling is equivalent to the numerical value treated by the sowing belt, but the final unit area spike number is lower than that treated by the sowing belt, and the spike rate is not obviously different from that treated by the sowing belt.
As shown in fig. 1, the illumination interception rate of the canopy processed by the sowing belt has no significant difference between the tillering middle stage and the broadcasting processing, and the illumination interception rate of the canopy processed by the sowing belt is significantly higher than that of the broadcasting processing in the young ear differentiation and full ear period, so that the ear forming rate is high and more effective ears are obtained under the sowing belt processing, and meanwhile, the uniformity of the sowing belt processing population is higher and the variation error is very small. The mechanical dibbling and tillering middle-stage canopy interception rate is low and has large variation, the canopy interception rate is gradually increased along with the generation of tillering and the high tillering and heading rate at the later stage, and the canopy interception rate of the mechanical dibbling and tillering at the heading stage is between the other two sowing modes. The higher canopy interception rate in the later period is beneficial to the grouting and fructification of rice and the improvement of the final yield.
Table 3 yield of ultra-high 1000 under different planting conditions and its constitutive factors.
Note: data are mean ± sd, and the same letters in the same column indicate no significant difference between the two, while different letters indicate that the two differ significantly at the 0.05 level.
In terms of yield performance, the yield of the seeding belt treatment is obviously higher than that of the mechanical dibbling treatment and is obviously higher than that of the broadcasting treatment, and in addition, the seed setting rate under the seeding belt treatment and the mechanical dibbling treatment is higher than that of the broadcasting treatment, which is probably because the more uniform individual distribution forms a more reasonable group structure, thereby being beneficial to the synthesis of the group photosynthetic products and the filling and filling of the seeds.
