The invention provides a sweet potato leaf powder processing technology with a high nutrition retention rate, which comprises the following steps: S1, putting sweet potato leaves into a dynamic fixation roller, and mixing nitrogen and carbon dioxide by adopting a nitrogen and carbon dioxide mixing generator to form nitrogen and carbon dioxide mixed gas, the nitrogen and carbon dioxide mixed gas is heated to 95 DEG C through a heat exchanger and sprayed out, the oxygen concentration in the dynamic fixation roller is maintained to be smaller than or equal to 0.5%, and the chlorophyll degradation rate of the sweet potato leaves is monitored through a near-infrared sensor by inhibiting the activity of polyphenol oxidase of the sweet potato leaves; according to the method, a weak acid environment is formed through CO2 dissolution to inhibit the activity of polyphenol oxidase and reduce the requirement for fixation temperature, active ingredients are reserved through three-area gradient variable-temperature drying and rapid dehydration and freeze-drying sublimation, energy consumption is reduced by 37%, heat stability is improved through polyphenol glycosylation, the bioavailability of beta-carotene is improved to 80% through nano embedding, and therefore nutrient loss is avoided, and the method is suitable for industrial production. The drying efficiency, color and flavor are improved.

The present utility model relates to a feed formulation for ZAMPEN native chicken (Gallus gallus domesticus) hardening stage characterized by comprising of a basal diet formulation and supplemental feed formulation made from fermented forages. The basal diet formulation comprises: of 1 wt.% molasses, 0.1 wt.% vitamins and minerals, or a combination selected from the group comprising: energy-source component of 4.75 wt.% cassava, 7 wt.%, corn bran, 50 wt.% corn yellow; a crude protein component of 3.9 wt.% copra meal, 20 wt.% fish meal and 12 wt.% soybean meal; and a calcium source component of 0.35 wt.% eggshell, 0.9 wt.% limestone. Whereas the supplemental feed formulation comprises: tricanthera, azolla, duckweed, and vegetable trimmings of pechay (Brassica rapa), mustasa (Brassica juncea), alugbati (Basella alba), kangkong (Ipomoea aquatica), and camote tops (Ipomoea batatas). The said formulation aims to significantly enhance feed intake of the native chicken while reducing feed costs.

The invention discloses an attractant composition for ipomoea salicifolia and application, and relates to the technical field of green prevention and control of agricultural and forestry pests. According to the invention, the S (-)-alpha-pinene, the ()-odontomicus enol, the ()-verbenone, the S-()-cis-verbenone and the trans-2-hexenol are combined for use, so that the attraction effect can be obviously improved by 5-10 times (compared with the independent use of the trans-2-hexenol), and the attraction specificity is ensured, that is, only the male and female adults of the assinus salicina are trapped.

The invention belongs to the technical field of desert ecological restoration, and discloses a hedge spiny seedling raising method and system for a field environment. The method comprises the following steps: collecting mature sedge seeds, treating for 3-5 minutes by using drum-type equipment at the rotating speed of 30-50 rpm, breaking the skin, and soaking the seeds in warm water at 38-42 DEG C for 10-12 hours; a modularized detachable seedling raising shed is adopted, movable non-woven fabric seedling raising bags filled with field soil, decomposed sheep manure (or biochar) and sand (the volume ratio is 5: 2: 1) are placed in the modularized detachable seedling raising shed, and an automatic drip irrigation system based on a soil humidity sensor is matched; and carrying out programmed seedling hardening 2-3 weeks before transplanting. According to the method, the embryo damage rate is controlled to be 1% or below, the seed germination rate is stabilized to be 90% or above, the transplanting survival rate reaches 90% or above, the water resource utilization efficiency is improved by 15-20%, operation is standardized, and the method is suitable for large-scale seedling raising in desert photovoltaic areas.

The present application discloses a sweet potato cadmium tolerance related protein IbMYB4 and its coding gene and application. The present application belongs to the technical field of biotechnology, and particularly relates to a sweet potato cadmium tolerance related protein IbMYB4 and its coding gene and application. The protein IbMYB4 is any one of the following: A1) a protein with an amino acid sequence as shown in SEQ ID No. 1; A2) a protein obtained by substitution, deletion and / or addition of amino acid residues of the protein of A1), which has more than 80% identity with the protein shown in A1) and has the same function; and A3) a fusion protein obtained by connecting a protein tag to the N terminal or / and C terminal of A1) or A2). By introducing the IbMYB4 coding gene into wild type sweet potato, the tolerance of the plant to heavy metal cadmium can be improved, and the IbMYB4 coding gene can be applied to sweet potato breeding, and has wide application space and market prospect in the field of agriculture.
