Improvement method for organic maturation of yellow mud fields

The invention discloses an improvement method for organic maturation of yellow mud fields. For an early season rice field, the improvement method includes the steps: 1), planting astragalus sinicus and applying inorganic fertilizer; 2), applying nitrogen fertilizer at a stage when astragalus sinicus sends forth a first true leaf, wherein scalar quantity of the nitrogen fertilizer is 6.9-10.35 kilograms per hectare; 3), reapplying the nitrogen fertilizer at a stage when astragalus sinicus grows vigorously, wherein scalar quantity of the nitrogen fertilizer is 17.25-34.5 kilograms per hectare; 4), taking astragalus sinicus as green manure to be returned to the field, and applying chemical fertilizer. For double cropping rice, the improvement method includes 1), directly returning straw of early season rice into field in situ, or applying livestock and poultry manure for soil maturation; 2), additionally applying nitrogen fertilizer, and adjusting C/N ratio of the straw; 3), applying rotten organic fertilizer or mushroom residue before seeding middle-season rice or late-season rice; 4), performing light dewatering and ventilating after transplanting of the middle-season rice or the late-season rice, and re-watering. By the improvement method, soil structure is improved, soil volume weight is lowered, soil cation exchange quantity is increased, community structure of soil microorganisms and soil enzyme activity are affected.

Narcissus late season yellows virus detection kit and method

The invention relates to a narcissus late season yellows virus detection kit and method specific for narcissus late season yellows virus detection. The knit comprises an outside upstream primer, an outside downstream primer, an inside upstream primer, an inside downstream primer, an RTBuffer, an RNA enzyme inhibiting factor, reverse transcriptase, dNTPs, a PCR Buffer, MgCl2, TaqDNA polymeras, positive control, negative control and RNase-free ddH2O. Specific primers are designed according to narcissus late season yellows virus gene sequences, and a nested RT-PCR technology is utilized to detect narcissus late season yellows viruses. Firstly, inverse transcription is carried out with extracted RNA as the template to synthesize cDNA, first-round PCR amplification is carried out with the cDNA as the template, second-round PCR amplification is then carried out with first-round PCR products as the template, and agarose gel electrophoresis detection is conducted on amplification products: if a specificity target fragment of the size of 539bp appear, the judgment result indicates that a detected virus is a narcissus late season yellows virus. The narcissus late season yellows virus detection kit and method have the advantages of being strong in specificity, high in sensitivity, good in accuracy and short in detection time and are suitable for quickly detecting and monitoring narcissus late season yellows viruses in entry ports, exit ports and agricultural production.

Method of improving lodging resistance of high-quality rice variety Xiangyaxiangzhan

PendingCN109169076AReasonable group structureSteady tiller growthData processing applicationsFertilising methodsPanicleTotal nitrogen
The invention discloses a method of improving the lodging resistance of a high-quality rice variety Xiangyaxiangzhan. The method comprises steps: (1) the target yield of Xiangyaxiangzhan is determined; (2) the land capacity yield is determined; (3) the reasonable total amount of nitrogen application is calculated, wherein the total nitrogen application amount calculation method is: the total nitrogen application amount (kg/mu)= [the target yield per mu (kg) - the land capacity yield per mu (kg)]*R/100, R is a nitrogen application constant and refers to the nitrogen application amount for producing per 100 kg of rice on the basis of the land capacity yield, R has different values for early and late seasons, R=7 in an early season and R=8 in a late season; and (4) the nitrogen application ratio of a base fertilizer to a tillering fertilizer to a panicle fertilizer is reasonably distributed. According to climatic conditions, soil fertility and variety characteristics, the reasonable nitrogen application amounts during the full-growth period of rice and the planning and management ratio of the nitrogen fertilizer in early, middle and late stages of the rice growth are designed by the method, the number of stems and tillers during the rice growth process develops steadily, the population structure is reasonable, the plant height is shorter, the internode is shortened, and the lodging resistance of the variety is thus improved.

The method of building inner ridges under the co-cropping mode of shrimp and rice

The present invention discloses an inner-periphery ridge building method for a shrimp and rice joint culturing mode, wherein a ridge is built, in a rice field with an enclosed ditch, along the enclosed ditch; the ridge has a height of 20-40 cm and a bottom width of 30-50 cm; the ridge goes around the rice field and an outer edge of the ridge has a distance of 40-60 cm from an inner edge of the enclosed ditch; and the soil for building the ridge comes from the outer side of the ridge, and 15-25 cm thick surface soil is fetched on the outside surface of the field to build the ridge. When field sunning is needed in a rice growing season, a water outlet is arranged on the inner ridge and the water surface of the enclosed ditch is made to be lower than the field surface by using drainage and irrigation equipment; during rice fertilization, the water outlet on the inner ridge must be blocked to prevent fertilizers from flowing into the ditch; and after middle-season rice or late-season rice have been harvested, the field is irrigated to be filled with deep water, ensuring that the water surface is higher than the inner-periphery ridge, so that the entire field surface can culture small lobsters; in the following year and before transplanting of the next-season rice, the inner-periphery ridge should be reinforced to prevent leakage. The inner-periphery ridge building method of the present invention enables the water surface of the cultural ditch and the water surface of the rice field to be manually isolated and controlled, facilitating farming operation and water and fertilizer management of the rice field.
