The invention discloses a silverweed cinquefoil root flowering fertilizer composite formula and application thereof, and relates to the technical field of compound fertilizers, the silverweed cinquefoil root flowering fertilizer composite formula comprises, by weight, 15-25 parts of a nano carrier, 28-44 parts of an organic raw material, 7-15 parts of an inorganic raw material, 8-12 parts of biological bacteria, 0.2-0.3 part of a biological regulator, and 6-11 parts of a trace element composition; wherein the nano carrier is prepared from 12 to 20 parts of nano diatomite and 3 to 5 parts of nano hydroxyapatite; the nano diatomite is obtained by sequentially stirring a 2mol / L NaOH solution at the temperature of 60 DEG C for 2 hours, adjusting the pH value to 6.0 by a 1mol / L HCl solution and drying at the temperature of 105 DEG C; the specific surface area of the nano diatomite is greater than or equal to 85 m < 2 > / g The application has the effects of meeting the nutrient and physiological requirements in the key flowering period of the potentilla anserine and improving the flowering rate and the fruit setting rate of the potentilla anserine through nano-carrier modification and functional component optimization.

This invention discloses an improved breeding method for leafy grasses. Using Rumex (hybrid sorrel, abbreviated as Rumex) as the female parent and Rumex rubrotinctum (commonly known as Rumex 'sheep's hoof') as the male parent, a first-generation leafy grass hybrid is obtained. This first-generation hybrid is backcrossed with Rumex to obtain a first-generation backcross. This first-generation backcross is then subjected to 3-4 generations of self-pollination. Through marker-assisted selection and agronomic trait identification, genetically stable leafy grasses without phenotypic segregation are obtained. Finally, improved original seed varieties are obtained through primary seed propagation. The newly added combination of directional backcrossing + multi-generation self-pollination + marker-assisted selection in this invention is the first such disclosure in the field of leafy grass breeding. The leafy grasses obtained by this breeding method have a protein content ≥35%, a 20% increase in salt and alkali resistance, and a genetic stability of over 98%. The breeding process is clearly defined with quantified parameters, allowing for large-scale propagation. It overcomes the technical shortcomings of traditional hybrids and is suitable for commercial cultivation of leafy grasses, possessing significant economic and application value.
