Description

Technical Field

[0001] The invention relates to the technical field of seed cultivation, in particular to a method for preparing leguminous plant grains. Background Art

[0002] Leguminous forage grass planting pellets are a technology developed and improved on the seed pellet coating technology. Making seeds into planting pellets can increase the ability to resist drought, insects and diseases during the seedling stage and the growth process, promote seedling establishment and improve its competitiveness. Traditional seed pellet coating technology uses adhesives to stick seeds and fillers into pellets, but the economic cost of this method is relatively high. At present, there is still a lack of some technical methods for making planting pellets with low-cost and easily available materials, as well as formulas that are more suitable for the growth of leguminous forage. Therefore, the study of an optimal leguminous forage pellet formula is essential for the subsequent forage growth and establishment. Summary of the invention

[0003] (I) Purpose of the invention

[0004] The invention proposes a method for preparing leguminous plantation granules, which aims to use "grass seeds + fertilizer + soil" to make granules for subsequent reseeding to repair artificial grassland. Most of the nutrients in the fertilizer used in the leguminous plantation granules of the invention can directly act on the growth process of forage grass, especially in the early stage of forage grass growth, to improve the establishment of reseeded grass seeds. Sowing and fertilizing are carried out at the same time, which is conducive to drone operation and reduces labor input. It takes into account both the reduction of economic costs and the improvement of forage grass production.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present invention provides a method for preparing leguminous plant grains, comprising: selecting forage seeds with a purity of more than 90% and a germination rate of more than 80%;

[0007] Seeds, soil and fertilizer are mixed evenly in proportion, and extruded by a double-roll extruder with an extrusion strength of 6-20N and a rotation speed of 55r / min to produce ellipsoidal particles with a length of 16mm, a width of 11cm and a height of 10mm. The soil passes through an 8mm sieve and has a water content of 20%. The ratio of the mixture of seeds, soil and fertilizer is 1:50, and the fertilizer includes organic fertilizer and inorganic fertilizer.

[0008] Preferably, the seeds include any one or more combinations of white clover, red clover, and crimson clover.

[0009] Preferably, the organic fertilizer is fermented with local cow dung to obtain cow dung fermented organic fertilizer.

[0010] Preferably, the inorganic fertilizer comprises superphosphate.

[0011] Preferably, the process is carried out according to the following components: 18-57 parts of soil, 35-76 parts of organic fertilizer fermented from cow dung, and 3 parts of superphosphate.

[0012] Preferably, the inorganic fertilizer also includes 3 parts of calcium magnesium phosphate type improver.

[0013] Preferably, the inorganic fertilizer also includes 2.5 parts of mineral source potassium humate

[0014] Preferably, Bacillus subtilis and Bacillus licheniformis are added to the calcium magnesium phosphate type improver.

[0015] Preferably, the ratio of soil to organic fertilizer is any one of 2:8, 4:6, and 6:4.

[0016] Preferably, the soil comprises 54.9 parts and the organic fertilizer comprises 36.6 parts of cow dung fermented from cow dung.

[0017] The above technical solution of the present invention has the following beneficial technical effects:

[0018] The method of the present invention combines soil, fertilizer and seeds, and when used subsequently, can effectively improve the rhizosphere environment of the reseeded forage grass, improve nutrient utilization efficiency, promote the establishment of the reseeded forage grass and improve its competitiveness with weeds;

[0019] The soil provides a certain degree of protection for the seeds, preventing them from being eaten by birds, insects, and mice, and provides a warm and water-retaining environment for the seeds to germinate and grow normally later;

[0020] The "adhesive" used in the present invention is soil, which can not only combine the seeds with fertilizers, but also provide a certain storage space for the seeds to avoid direct contact with fertilizers and being burned to death. In addition, soil is easy to obtain and economical, and will not cause pollution. BRIEF DESCRIPTION OF THE DRAWINGS
