Double cropping rice nitrogen-saving high-yield production method

The invention relates to a double cropping rice nitrogen-saving high-yield production method. A double cropping rice planting region is selected; 15 to 30 days before late rice is harvested, astragalus sinicus planting is carried out; after the late rice is harvested, ditching is carried out according to an astragalus sinicus planting technology; 30 to 50kg of calcium magnesium phosphate fertilizer is applied per mu; 1 to 2kg of potassium chloride used as a base fertilizer is applied per mu; 10 to 15 days before early rice is transplanted, dry tillage and plowing pressing are carried out; land preparation is carried out according to the early rice planting requirements; azolla is bred; and after shoal water of field water, which has a height of 1.5 to 3.5cm, is kept for 8 to 10 days, the base fertilizer is applied to carry out early rice transplanting. During growth of the early rice and the late rice, duckweed utilization is naturally carried out; before the late rice is transplanted, a sustained-release nitrogen fertilizer is applied in one step as the base fertilizer; and on mid-to-late September in the next year, circulation operation of farming of planting astragalus sinicus green manure crops and the like is carried out. According to the invention, astragalus sinicus green manure is planted during the slack winter season of double cropping rice planting, the azolla is bred during growth of rice, the rice special sustained-release nitrogen fertilizer is applied to the late rice in a decreasing manner, the astragalus sinicus and the azolla are utilized to fix nitrogen and adsorb carbon, the land is maintained by the land, organic materials and an organic nitrogen source are provided for rice, nutritive substances in the double cropping rice field, which are easy to loss, are adsorbed, non-point source pollution is reduced and fertilizer supply and the fertilizer requirement of rice are coordinated and consistent.

The invention discloses a litopenaeus vannamei and fish mixed culturing ecological breeding method. A pond with brackish water is selected, during a slack winter season, spiral shell harm is removed, filiform algae are cultured in a directed mode, deposit phosphori in the pond bottom are adsorbed and removed, on around the Tomb-sweeping Day in spring, quick lime dry method pond poisoning is carried 20 days before culturing, 10 cm water adding is carried out before fry adding planning, bleaching powder is used for soaking a disinfecting tank bottom for 12 h, 80 cm water adding is carried out, after water adding is completed, oil tea cakes which are soaked by warm water for 24 h in advance are splashed, and organic fertilizer obtained through microbial fermentation is hung at the side of the pond. After water cultivating, young shrimps are subjected to out-of-cage breeding, after seven days, small-specification mixed-culturing fingerlings obtained after salinization are subjected to out-of-cage breeding, on the 35th day, large-specification mixed-culturing fingerlings are subjected to out-of-cage breeding, then the water level is deepened gradually, the water level is controlled to be 1.1 m-1.2 m, in the early period, feeding is carried out 2 times a day, in the medium-later period, feeding is carried out 3 times a day, computing is carried out according to 2%-8% of body weight, breeding is carried out for 80-100 days, and litopenaeus vannamei is harvested. Mixed fishes with the proper matched density are used for eliminating sick and weak shrimps, the infection source of sick shrimps is removed, prawn abnormal group swimming is avoided, sick shrimps are reduced, and the success rate of culturing is improved.

Method of overlaying film on cigarette ridge and planting green manure in slack winter season

ActiveCN105359794AMake full use of the heat preservation and moisturizing effectImprove insulation effectClimate change adaptationPlant cultivationPlastic mulchGreen manure
The invention discloses a method of overlaying a film on a cigarette ridge and planting green manure in a slack winter season and belongs to the technical field of flue-cured tobacco plantation technology. The method comprises the following steps of (1) applying base fertilizer on a cigarette land in March of the first year, ridging and overlaying a mulch film, conducting fixed-distance transplanting according to normal progress and managing field, and maintaining the film on the land for the whole process, (2) eliminating residual cigarette plants on the cigarette ridge after flue-cured tobacco harvest in September of the first year, punching holes on two sides of the film-overlaid cigarette ridge in a parallel way, (3) eliminating the mulch film and turning over oilseed rape via a rotary cultivator after oilseed rape sedge period finishes in the next year and burying the oilseed rape into the soil for two to three months, then planting cigarettes again and repeating the shifting cultivation process. In the second step, the hole punching depth is 13 to 16cm; the distance between two holes on the same side is 0.2m; and oilseed rape seeds are placed in each hole. A problem of oilseed early blossoming can be avoided; labor intensity and labor cost can be reduced; soil fertility can be improved; and cigarette field shifting cultivation efficiency can be improved.
