The invention relates to a method for producing an organic water-soluble fertilizer by utilizing marigold fermentation press filtrate. Belongs to the fertilizer field. The compound fertilizer comprises a marigold water-soluble fertilizer and rosemary fermentation liquor, the marigold water-soluble fertilizer is obtained by performing pH adjustment on marigold fermentation press filtrate, performing solid-liquid separation, taking liquid, concentrating, cooling, settling and taking liquid. The rosemary fermentation liquor is obtained by fermenting rosemary waste residues through trichoderma asperellum, carrying out solid-liquid separation and taking liquid. According to the invention, two agricultural wastes are converted into high-value functional fertilizers, and integration of resource circulation and pesticide-fertilizer is realized. Through biological fermentation, the marigold water-soluble fertilizer provides growth-promoting nutrition and improves capsaicin synthesis, and trichoderma asperellum viable bacteria are introduced into rosemary fermentation liquor, so that pepper phytophthora blight is prevented and treated specially. The water-soluble fertilizer provided by the invention is especially suitable for pepper planting, and is also a universal water-soluble fertilizer.

The present application relates to the technical field of lutein extraction, and provides a green extraction method of lutein from marigold, which comprises the following steps: mixing marigold dry flower particles with deionized water to prepare slurry, and performing high-pressure homogenization treatment to obtain pretreated slurry; mixing the pretreated slurry with a deep eutectic solvent (DES) and performing countercurrent extraction under the protection of inert gas to obtain DES extraction liquid after filtration; preheating the DES extraction liquid and pumping it into a continuous flow fixed-bed enzyme reactor filled with immobilized lipase, and performing enzymolysis reaction under constant temperature to obtain an enzymolysis liquid; sequentially treating the enzymolysis liquid through a ceramic ultrafiltration membrane and a nanofiltration membrane; collecting the retentate of the nanofiltration membrane, adding preheated deionized water to the nanofiltration retentate, and performing low-temperature standing crystallization; and washing and vacuum freeze-drying the obtained crystals to obtain a lutein crystal product. Through the above technical scheme, the extraction rate of lutein is improved, and the problem of incomplete extraction caused by insufficient cell structure damage in the traditional extraction method is improved.

The invention belongs to the technical field of marigold particle processing, and particularly relates to a marigold particle processing technology and a marigold particle processing device.The marigold particle processing device comprises a machine body, a hydraulic machine is fixedly connected to the machine body, and an output shaft of the hydraulic machine penetrates through the machine body and extends to an inner cavity of the machine body; a plurality of inserting grooves are formed in the mounting plate, fixing rods are inserted into the inserting grooves, the bottom ends of the fixing rods are fixedly connected with a squeezing plate, and first limiting grooves are formed in the fixing rods; the multiple fixing blocks are fixedly connected to the top face of the mounting plate, sliding grooves are formed in the multiple fixing blocks, inserting rods are slidably connected into the multiple sliding grooves, and one ends of the multiple inserting rods extend into the multiple first limiting grooves and are in inserted connection fit with the multiple first limiting grooves correspondingly, so that quick disassembly and assembly of the squeezing plate are achieved; a user can quickly replace the type of the squeezing plate according to the size of the squeezing container, and the replacement efficiency of the squeezing plate is improved.

The application provides a marigold gene, a cloning method, an expression vector and application. Compared with the prior art, the TeLFI1 gene is cloned from marigold as follows: high-abundance expression sequences in leaves are assembled by using marigold transcriptome sequencing; then, specific PCR primers are designed by using primer design software Primer Premier, total RNA is extracted from marigold leaves, reverse transcription PCR is carried out, and the TeLFI1 gene is cloned. When the TeLFI1 is expressed in tomatoes, the leaf color can be changed, and mottled leaves or gold-edged leaves are formed. The expression of the TeLFI1 gene in tomatoes changes volatile flavor substances in the fruits.

The present application relates to the technical field of plant cultivation, and specifically discloses a method for crossbreeding of Tagetes erecta.The method for crossbreeding of Tagetes erecta comprises the following steps: (1) trimming the top of the calyx to the same level, and removing the petals of the ligulate flowers that exceed the calyx; (2) cutting the bottom of the flower bud, and removing a part of the flower bud to form a gap for exposing the small flowers in the remaining flower bud; the sequence of steps (1) and (2) is not limited; (3) cleaning all the small flowers carrying stamens from the gap; if the female parent only includes ligulate flowers, the small flowers refer to the ligulate flowers; if the female parent includes ligulate flowers and tubular flowers, the small flowers refer to the ligulate flowers and the tubular flowers.The method is simple in operation, time-saving and labor-saving, low in cost, and does not depend on male-sterile dual-purpose lines, and can quickly obtain hybrid species among Tagetes erecta germplasm resources.

The invention provides a method for preparing a feed from marigold straw and corn straw through micro-storage, which comprises the following steps: respectively harvesting and crushing marigold straw and corn straw, uniformly mixing the crushed marigold straw and corn straw, uniformly spraying water, inoculating a compound microorganism bacterium solution, and uniformly mixing to obtain a fermented material; and adding fermentation auxiliary materials into the obtained fermentation material, uniformly mixing, and carrying out anaerobic fermentation to obtain the marigold straw and corn straw micro-storage feed. The invention further provides application of the marigold straw and corn straw micro-storage feed prepared by the method, and the marigold straw and corn straw micro-storage feed is used for improving intestinal health of ruminants. The tagetes erecta straw and the corn straw which are wide in source are used as raw materials, efficient feed utilization of agricultural waste is achieved, the method is simple in process and low in cost, and the prepared feed enhances the nutritional value while improving palatability and digestibility and is beneficial to promoting ingestion of livestock and poultry and promoting healthy development of animal husbandry.
