An aerosol valve actuator with a top portion rotatable on a bottom portion. The entire top portion in one rotatable position is depressible vertically to actuate the valve. A click post and clicking rib provide a single click in each direction of rotation. Flanges on top and bottom portions interact to stop rotation as soon as each click occurs. Plastic springs interact with spring biasing members only when the top portion is in actuating position, and assure return of the actuator top portion to full upward position for rotation after actuation of even a short-stemmed valve. Downwardly extending flexible connecting flanges connect the actuator top and bottom portions. The top portion has a lower periphery with a plurality of upwardly extending indentations to overlie lateral ribs in the lower portion in actuation position. The top and bottom portions have interfitting cylinders to stabilize the top portion and maintain verticality.

The invention discloses a wide box and wide belt culture method for sugarcane. Sugarcane planting furrows with the space greater than 2m are dug, the sugarcane is planted in double rows in the sugarcane planting furrows, and soil filling and covering is carried out; a season of soybean, peanut or pepper is interplanted between the sugarcane planting furrows. The sugarcane planting line distance is increased, in addition, a season of short stem crops such as the soybean, the peanut or the pepper is interplanted between the lines, through adopting such a mode, the occupied area of the sugarcane is reduced, the ventilation and light transmission conditions are improved, diseases such as leaf spot diseases and dry top rot diseases generated under the high-temperature high-humidity and concealed conditions cannot easily occur, the generating rate of pests of ceratovacuna lanigera zehntner, mealybug and the like is smaller than that of the conventional single-crop sugarcane, more than 50 percent of pesticide and disease and pest prevention and treatment cost is reduced; in addition, the short stem crops are interplanted, the farm work operation is favorably carried out, and the field management efficiency is improved; and in addition, the short stem crops such as the peanut, the soybean and the like with nitrogen fixation capability are interplanted, partial nitrogen fertilizers can be provided for the sugarcane, and meanwhile, the consumption of chemical fertilizers is reduced.

The invention discloses a method for constructing a Camellia oleifera forest. The method comprises the steps of woodland selection, breeding and transplanting, shape control pruning, fertilizing management, strengthening and attending, pest control and prevention, fruit harvesting, fruit processing and the like. According to the method for constructing the Camellia oleifera forest, hybrid afforestation is adopted, a line of plants is interplanted every other 2-3 lines of the Camellia oleifera forest, a planting hole of a short-stem plant is formed at the interval of two planting holes of Camellia oleifera in the line of interplanted plants, and the distance between the planting hole of the short-stem plant and the planting hole of the Camellia oleifera tree is 50 cm. The method for constructing the Camellia oleifera forest has the advantages of being stable and high in yield, short in afforestation cycle, high in fruit rate, stable in product quality and good in quality.

The invention relates to a tobacco stem screening tube which is characterized by consisting of a screening tube device, a transmission device and a dust removing mechanism. The screening tube device essentially consists of a screening tube body, a rolling ring on the tube body, a sealing housing and a discharging port and a feeding cover and a discharging cover at two ends of the tube body; the screening tube body is welded by a feeding port section, a tobacco dust screen tube section, a short stem screen tube body, a middle and long stem screen tube body and a stem head outlet tube section. The dust removing system consists of a dedusting fan and a dedusting pipe that are installed on the feeding cover. The invention optimizes the stem screening technique and is integrated with stem screening and dust removing, thus solving the problems of poor screening effect and product quality resulting from manual screen cleaning due to screen blockage by tobacco stem, ensuring good product quality, preventing dust from flying through dust collecting, maintaining cleanness of the on-site production environment and saving energy and equipment occupation area as a plurality of original devices are integrated into one device.

The invention provides a method for selecting bi-layer rice, comprising following steps: (1) preparing basic-layer rice seed with normal seed preparing method by selecting short-stem rice variety or strain; (2) preparing high-layer rice seed with normal seed preparing method by selecting high-stem rice variety or strain; the difference in crown height during ear-homogenous period between the high-layer and basic-layer is 5-100 cm; (3) matching according to proportion of 50-98: 2-50 between basic-layer and high-layer, mixing evenly and getting bi-layer rice seed. The got rice variety can make full use of light and temperature more effectively and thus increase the rice yield potential by 5-30%.

The invention belongs to the technical field of plant cultivation and specifically relates to a planting method for pennisetum sinese. The planting method for pennisetum sinese comprises the following steps: (1) preparing soil: selecting land with deep soil layer and sufficient water source, trenching and applying base fertilizer; (2) planting: selecting the mature plants which are 6-month old or older, selecting healthy stalks without pest and disease damage as parent stalks, tearing off the blades wrapping axillary buds, soaking for 24 hours with 0.6% ammonium molybdate solution, and then taking two knots as one section, cutting each section into 40-50cm short spikes and adopting a short stem cuttage method for planting two rows in each trench; (3) fertilizing: after intertilling and weeding, applying the special fertilizer to the pennisetum sinese for one time in rainy days. According to the invention, in the pre-treating manner of soaking the parent stalks with the ammonium molybdate solution, the nitrogen fixation function and the germination of the pennisetum sinese can be boosted. The special fertilizer is applied, so that the growth rate of the pennisetum sinese can be increased, the pennisetum sinese can quickly grow and the survival rate is high.

The invention relates to an intercropping planting method for corn and foxtail millet. According to the intercropping planting method for corn and foxtail millet, the intercropping ridge ratio of corn to foxtail millet is 1:1.5; three rows of foxtail millet are sowed in each ridge; two or three rows of corn are sowed in each ridge; and the foxtail millet or the corn sowed in each ridge is planted in a dog biting line mode. A traditional large-scale corn planting mode is broken through by the intercropping planting method, crops with tall and short stems are combined on one field, so that the high-low difference is formed, and the crops are good in ventilation and resistant to wind and lodging; and in addition, the corn can keep wind away from the foxtail millet, resist cold and shade the foxtail millet. Through the planting method, the yield of the corn is the same as that of corn planted in a large area, the yield of the foxtail millet is increased by 0.4 times per hectare, limited land resources are utilized better, and the purpose of increasing the yield and revenue for peasants is achieved.
