The invention relates to a fertilizer for rice dry seedling and a preparation method thereof. The preparation method comprises the following steps: mixing ammonium sulfate, ferrous sulfate, phosphogypsum, potassium chloride and monoammonium phosphate, blending uniformly, pulverizing to obtain materials with a granularity less than 1 mm; granulating the materials with vapor in a drum granulator toachieve the granulation rate up to 70 to 90%; oven-drying the granulated materials into a drier with the furnace temperature of 500 to 550 DEG C, the head kiln temperature of 500 to 550 DEG C and thetail kiln temperature of 80 to 90 DEG C; cooling the dried materials in a cooler to reduce the temperature of the materials below 50 DEG C; sieving the cooled materials in a drum grading sieve to obtain materials with the granularity of 1 to 4.75 mm; and packaging in bags. The fertilizer contains nitrogen, phosphorus, potassium and trace elements, not only can prevent the occurrence of diseases such as large-area yellowing and death of seedlings, yellow mosaic, sheath blight and bakanae but also can promote the growth of the rice root system, improve the utilization rate of the fertilizer andensure the yield and the income increase of high-quality rice. The preparation method has the advantages of simple process, convenient operation, reduced cost, labor saving and remarkable effect.

The invention relates to a natural keratin composite fertilizer and a method for preparing the same. The paddy seedling raising farming fertilizer at present has unqualified product quality and cannot be applied widely. The natural keratin composite fertilizer comprises the following components in portion by weight: 75 to 85 portions of natural keratin raw material, 12 to 20 portions of sulphate inorganic compound, and 2 to 4 portions of complexing agent. The natural keratin composite fertilizer is applied to paddy seedling raising farming fertilizer and the method for preparing the same.

The present invention is one kind of seed coating agent and its coating process. The hybrid rice seed coating agent consists of the following active components: carbendazim 7-8 weight portions, thiram 7-8 weight portions,paclobutrazol 0.15-1.3 weight portions and prochloraz 0.3-2.66 weight portions. The coating process with the hybrid rice seed coating agent includes the following steps: stoving water content of seed to below 11 %; coating seed in a seed coating machine in the ratio between the seed coating agent and seed of 1 to 40-70; and stoving the coated seed to water content below 13.0 %. Treating rice seed with the seed coating agent can raise the germination rate and rice seedling forming rate obviously, raise rice seedling quality, and result in other positive effects.

The invention discloses a method for breeding rice three-nursery breeder seeds by raising rice seedlings on a seeding tray, is suitable for the planting selection of rice filial generation, and belongs to the technical field of rice breeding. By the method, the problems of residues of rice grains (weed rice seeds or shattered rice in the previous year) of rice seedling beds, assorted seeding and transplanting links, slow seedling recovery after transplanting, large difference of single-plant growth and difficulty in guarantee of the purity of produced breeder seeds are solved. According to the method for producing the rice three-nursery breeder seeds, the production technology of rice ear-row nurseries, ear-line nurseries and breeder seed nurseries and the technology of raising the rice seedlings on the rice plastic seeding tray are combined, the rice seedlings of which the roots have nutritional soil blocks and which are easy to disperse with each other are cultivated by using a plastic seeding tray bowl, and the ear-row (line) nurseries are established by fixed-point single-bowl rice seedling transplantation in fields to perform the comparison of choice of the ear-row (line) nurseries, so that the opportunity of mixing seeds of the rice seedling beds is avoided completely to facilitate the improvement of the selection efficiency, propagation coefficients and purity of the breeder seeds.

The re-mixed fertilizer contains regulator in 0.5-25 wt% and inorganic chemical fertilizer in 75-99.5 wt%, and the regulator is the mixture of concentrated sulfuric acid and organic matter in the weight ratio of 1 to 3-8. The preparation process includes sieving or crushing organic matter as carrier and mixing with concentrated sulfuric acid to react for 10-30 hr to obtain the regulator; mixing inorganic chemical fertilizer; mixing the regulator and the inorganic chemical fertilizer through stirring to obtain the re-mixed fertilizer contains regulator. The present invention can regulate the pH value of surface soil layer and paddy field shallow water layer, meet the requirement of rice seedling to various nutritive elements, create one ideal shallow soil environment and raise the utilization of fertilizer and crop yield.

The invention discloses a cultivation method for Koshihikari rice. The method comprises the steps of soil preparation, sowing, seedling cultivation, transplantation, fertilization and water management. The sowing and rice field management measures for timely late sowing, sparse sowing, previous promotion and subsequent control are adopted; according to a straight-line fertilization method, under the condition that the total N application amount is invariable, the N application ratio of a base fertilizer to a tillering fertilizer to an earing fertilizer to a granular fertilizer is 1:1:1:1; according to an improved K application method, K serves as the base fertilizer or an additional fertilizer. According to the cultivation method, the Koshihikari rice growth and development law is coupled with a cropping system, ecological conditions, soil conditions and production conditions of Huang-huai rice areas to form a specific cultivation method, the problems of lodging and premature senility are effectively solved; therefore, a high yield is gained.

The invention discloses a method for simulating mechanized rice transplanting plot experiment by pot rice seedling hole planting, and belongs to the technical field of a rice breeding technology. The problem that mechanical transplanting is difficult to realize because of a relatively small area of a mechanized rice transplanting plot is overcome. According to the method, a rice seedling throwing and raising technology and a rice variety regional test technology are combined so as to achieve requirements of a mechanized rice transplanting technology; mechanized transplanting rice varieties which are suitable for locally planting are screened out by quantitative pot seedling for seedling throwing, and stimulating rice mechanical transplanting by fixed-point hole planting; the mechanized transplanting rice varieties replace conventional hand-transplanted seed-bed seedlings or mechanized-transplanting tray-nursing seedlings; manual rice seedling separating and transplanting is changed into pot seedling fixed-point pot planting; the transplanted rice seedlings are quick in reviving and good in premature, and have the characteristics of having nutrient soil in roots of mechanized-transplanting rice seedlings, being not damaged in roots during seedling separating, being straight in transplanted seedlings, consistent in seedling quantity per planting hole, quick in reviving, early in tillering and the like. According to the method, the accuracy and the scientificity of the mechanized rice transplanting plot experiment are improved.

The invention discloses a rice-seedling mechanical-transplanting and raising matrix, comprising the following components in parts by weight: 10-30 parts of fermentation straw coarse grains, 70-90 parts of non-toxic wastes in the fermentation industry and 0.1-2 parts of auxiliary materials, wherein the industrial non-toxic wastes are biogas residues generated in alcohol fermentation; the auxiliary materials are one or more of nutrient elements, a dwarfed strong seedling agent, a root growth promotion agent and a safety agent; and the nutrient elements are selected from one or more of nitrogen, phosphorus, potassium, zinc, boron and silicon. The rice-seedling mechanical transplanting and raising matrix disclosed by the invention has the advantages of easiness in obtaining materials, low production cost and good rice-seedling raising effect.
