Method for increasing yield of double cropping rice by turnover and fertilizer saving of Astragalus sinicus L. and straw in rice field

The invention belongs to the technical field of fertilizer-saving high-yield culture in agricultural production and relates to a method for increasing yield of double cropping rice by turnover and fertilizer saving of Astragalus sinicus L. and straw in a rice field. Specifically, the method includes that during growth of early rice, green Astragalus sinicus L. is overturned and pressed to return to the field so as to replace part of nitrogenous fertilizer, and during growth of late rice, straw of the early rice is returned to the field to replace part of nitrogenous fertilizer, and purposes for nitrogenous fertilizer conservation and high yield are achieved in the integral production cycle of double cropping rice. The method solves the problems that areas of vacant fields in winter are enlarged, the rice field is deteriorated, ecological cost for rice production is increased, and fertilizer utilization rate is seen low and the like in a rice cropping system of southern China. The method is a cultivating technology high in yield, nitrogenous fertilizer saving and lower in N2O emission and provided for increasing yield of the double cropping rice, reducing fertilizer investment and increasing fertilizer utilization rate.

Method for mechanically harvesting winter rape efficiently with low power consumption

The invention discloses a method for mechanically harvesting winter rape efficiently with low power consumption. The method comprises the following steps of: A, constructing a rape group suitable for mechanical harvest: selecting the variety suitable for mechanical production, performing mechanical precise-quantity direct seeding when the soil water content is 30 to 40 percent, and constructing an ideal group and a plant type by fertilizer and water application and disease inset pest and weed control; B, adjusting a mature period: spraying a ripener two to three days before the harvest of rape seed ripening stage in the regions of contradictory seasons; C, harvesting at right time: observing and measuring the morphological physiological index of the plant before the harvest of the rape, wherein more than 95 percent of siliques, namely yellow loquat fruits in the cropland are suitable for mechanical harvest; D, mechanically harvesting and measuring loss rate: harvesting by a special rape harvesting mechanism in a combining way in the period suitable for harvest; E, smashing and returning rape straw to the cropland: flooding the straw in water immediately after the harvest of rape, decaying and returning to the cropland. The method is easy and convenient to operate, improves a one-time efficient branch height, reduces the branch number, reduces the thickness of the pod layer, solves the problems of high harvest loss rate, and improves the yield.
