The textured transparent conductive layer according to the invention is deposited on a substrate intended for a photoelectric device and exhibiting a surface morphology formed from a sequence of humps and hollows. It is characterized in that its hollows have a rounded base with a radius of more than 25 nm; the said hollows are virtually smooth, which is to say that, where they exhibit microroughnesses, these microroughnesses have a height on average of less than 5 nm; and its flanks form an angle with the plane of the substrate whose median of the absolute value is between 30 DEG and 75 DEG .

The invention discloses a double-cut surface high-low level joint grafting technology for Torreya grandis. The joint grafting technology is a new grafting method that the long cut surface of a stock is inwards cut bias from bottom to top to the truncation surface, and moreover, the root of the long cut surface of the stock is vertically cut downwards along the part between bark and xylem to form the short cut of the stock; the long cut surface of a scion and the long cut surface of the stock are grafted in a joint manner; the short cut surface of the scion is inserted into the short cut of the stock, and thus, not only is the conjunction degree of the scion and the stock high, are the scion and the stock high more tightly and is the healing power stronger but also the scion is basically vertical upwards, and crown inclination cannot occur after the scion survives; only branches, a terminal bud and 4-5 leaves of the scion are kept, so that the transpiration of the blades is reduced, and the moisture loss is reduced. According to the joint grafting technology disclosed by the invention, only the terminal bud, which is about 1cm, of the scion is kept, and thus, the distance from the stock to the terminal bud is shortened, the sprouting capability of the terminal bud is enhanced, and the grafting survival rate reaches up to 98 percent. A Torreya grandis grafted plant is upright; the crown does not incline; the grouting capability is strong; the crown can be rapidly formed.

The invention discloses an organic rice cultivation method by utilizing farmland and rice chaff weeding, belonging to the technical field of rice production. The method comprises the steps of: soaking in shallow water; ploughing for two times or three times; transplanting strong seedlings; broadcasting rice chaff; conducting later field management and other steps. In the method, drainage is required at first and then ploughing is carried out each time, which aims at carrying away sheathed monochoria herb without spouting and floating on the surface of a water level and seeds of chufa through drainage; the rice chaff fertilization faster improve the field temperature so as to create a good sprouting environment for weed seeds, and also can reduce the oxygen content under the surface layer, thus preventing the normal growth of the weed roots and achieving purpose of killing weeds, further increasing the content of organic matters, being beneficial to improvement of rice quality. The organic rice cultivation method can be popularized and applied in rice cultivation regions.
