Effects of Different Density on Orientation Value of Rice Black Hull 9003- 1 Leaves

Abstract: Taking Heidao 9003- 1, a tall rice variety, as the material, this experiment studied the canopy structure characteristics of rice population and the leaf orientation values of different levels of leaves in the canopy, in order to provide theoretical basis for high-yield cultivation of rice. As for rice black husk 9003- 1, when the density is 330,000 stalks /hm? The maximum leaf orientation value is 19. 1 1, that is, the leaves grow excessively upwards, and the density is 300,000 stems /hm? The transmittance in the group is high. Through the above investigation, it is proved that the suitable planting density of rice 9003- 1 black chaff is 300 thousand stalks /hm? .
