This invention relates to a controlled-release potassium granule, comprising a potassium nutrient core and a polyurethane coating layer covering the surface of the potassium nutrient core. The potassium nutrient core uses at least one of potassium chloride and potassium sulfate as the potassium source material, and also includes a functional carrier, a potassium activator modifier, and a binder. After the potassium source material, functional carrier, potassium activator modifier, and binder are mixed evenly, the potassium nutrient core is formed through granulation and drying processes. This invention adopts a separate potassium coating design, breaking the limitations of existing nitrogen, phosphorus, and potassium mixed coatings. It can be flexibly mixed with separately coated nitrogen, phosphorus, and other nutrient fertilizers in any proportion, and can precisely adjust the mixing ratio of potassium with other nutrients according to the nutrient requirements of different crops (such as grain crops and fruit and vegetable crops) and different growth stages (such as seedling stage, fruit expansion stage, and grain filling stage), so as to achieve personalized precision fertilization and adapt to the personalized needs of various crops.

The application discloses selenium-rich rice with multiple amino acids and a preparation method and application thereof, and belongs to the technical field of cross between agricultural planting and deep processing of agricultural products. The rice meets four core indexes: the proportion of organic selenium is greater than or equal to 80% (of which the proportion of selenomethionine is greater than or equal to 70%), the index of human essential amino acids is greater than or equal to 0.95, the content of leucine and arginine is significantly strengthened, and the content of characteristic aroma substance 2-AP is greater than or equal to 200 mu g / kg. The preparation method comprises the following steps: at the booting stage of rice, a first nutrient solution with a specific ratio of four kinds of amino acids is sprayed to optimize the metabolic basis; at the early stage of grain filling, a second nutrient solution containing selenomethionine and proline is sprayed to realize synergistic transport; and finally, the harvested rice is subjected to specific temperature and humidity after-ripening treatment. Through unique time sequence design and material combination, the method improves the selenium nutrition, amino acid quality and "roasted nut aroma" flavor of the product, and provides technical support for the development of high-quality rice.

The application provides an amino acid application method for improving wheat grain weight and drought resistance, and belongs to the field of agricultural technology.The method mainly sprays glutamic acid solution at the wheat heading stage and the flowering stage, and the method can significantly improve the drought resistance of plants and offspring wheat at the grain filling stage.The results of examples show that the method can improve the SPAD value, photosynthetic rate and antioxidant enzyme activity of wheat under post-flowering drought stress, prolong the grain filling duration of wheat, and finally increase the dry matter accumulation amount, total starch content and grain weight.Meanwhile, the method can also maintain the germination energy, alpha-amylase activity, soluble sugar content, plant height, root number, total root surface area, total root volume of offspring wheat under PEG-6000 stress, reduce the relative permeability of the cell membrane, reduce the harm of drought stress to offspring wheat, and finally show that the adaptability of offspring wheat to drought stress is enhanced.

This invention belongs to the field of crop cultivation technology and provides a smart soil moisture monitoring and micro-sprinkler irrigation method for high-yield wheat cultivation in sandy loam black soil areas. The method includes: S1. Variety selection and seed treatment; S2. Straw return and land preparation; S3. Basal fertilizer application; S4. Sowing; S5. Smart soil moisture monitoring and micro-sprinkler irrigation; S6. Delayed nitrogen fertilization and topdressing at critical stages; S7. Other field management techniques according to local high-yield field methods. By integrating key technologies such as soil moisture monitoring, micro-sprinkler irrigation, and optimized nitrogen fertilizer management, precise water and nitrogen supplementation are applied based on the water deficit in the 0-40 cm soil profile during the key stages of jointing, booting, flowering, and grain filling, aiming to achieve synergistic high wheat yield and efficient water and fertilizer utilization. This invention significantly improves wheat yield in sandy loam black soil areas and has significant practical value.

The present application relates to the field of agricultural crop cultivation, and specifically discloses a water management method for high yield and efficiency of low-cadmium rice varieties, which comprises: intermittent rewatering irrigation during the grain filling stage of rice; and maintaining a shallow water layer of 2-5 cm during the remaining growth period of rice. The intermittent rewatering irrigation is: irrigating to a water layer of 3-5 cm, rewatering when the field soil water potential reaches -20 kPa after natural drying, and repeating the cycle until the end of the grain filling stage. The present application selects the grain filling stage to implement intermittent rewatering, and uses shallow water layer management during the remaining growth period, which significantly improves the yield of rice while stably controlling the cadmium content of brown rice below the national safety standard, achieving the synergistic effect of high yield and safety of low-cadmium rice. The method is simple to operate and suitable for large-scale popularization and application in cadmium-polluted rice areas.
