The invention discloses a digital method for quickly evaluating the loss degree of alfalfa diseases and insect pests. It analyzes the lesion area and non-lesion area of ​​alfalfa leaves, summarizes the common disease degree and its RGB color component rule, and constructs the leaf lesion area and non-lesion area accordingly. Lesion color decision tree component system. It integrates the visual processing flow of digital pictures and is suitable for non-computer professionals to operate and use; it also has functions such as batch processing and data export, and is suitable for processing large amounts of data; Geometric deformation improves calculation accuracy; binary images of healthy and unhealthy areas of leaves are constructed, and display and comparison are provided; it is suitable for leaves whose length and width are less than 0.5m, and the range and accuracy are as follows: The statistical accuracy of the lesion area of ​​the alfalfa leaf is more than 95% in the range larger than 1mm.

The invention discloses an alfalfa tablet, which comprises the following components in parts by weight: 80-100 parts of freeze-dried powder of alfalfa leaves, 80-100 parts of freeze-dried powder of hamburger coffee and fragrant barley, 10-12 parts of wolfberry powder, and 5 parts of chrysanthemum powder. ~10 parts, 8~12 parts of calcium citrate, 3~5 parts of magnesium stearate, 6~8 parts of hydroxypropyl methylcellulose, 10~15 parts of starch, 5~10 parts of vitamin C, 5~8 parts of vitamin B . The acidic amino acids aspartic acid and glutamic acid contained in the hamburger coffee coriander of the present invention can well remove the grassy smell of the alfalfa leaf itself, so that the prepared alfalfa slices can eliminate the grassy smell and have a fresh and delicious flavor. The taste is deeply loved by consumers, which has greatly promoted the application of alfalfa leaves.

The invention discloses a method for using sterilized alfalfa leaves instead of sterile filter membranes as a three-parent hybrid carrier to improve the efficiency of fluorescent plasmid transfer conjugation and transfer of rhizobia fluorescently labeled strains, which can be used to efficiently construct rhizobia CFP cyan fluorescent protein genes To mark the bacterial strain, the method is as follows: take the young leaves of alfalfa, wash them with distilled water, place the leaves evenly in a single layer in a petri dish, and sterilize them; take out the leaves with sterile tweezers, and stick them on the surface of TY medium , and cover the Petri dish. In the process of three-parent hybridization, instead of the microporous membrane, the mixed growth culture of donor bacteria, auxiliary bacteria and recipient bacteria is carried out. Compared with the microporous filter membrane as the hybrid carrier, using alfalfa leaves as the hybrid carrier can increase the conjugative transfer rate of fluorescent plasmids by 8.4-11 times, and the difference reaches a significant level; because the raw materials used are renewable and easily obtained alfalfa plants The leaves, raw materials are cheap and easy to obtain, and the operation is simple and convenient, which is suitable for the construction of rhizobia fluorescently labeled strains.

The invention discloses a preparation method of an alfalfa leaf protein peptide beverage. The method includes: using fresh alfalfa leaves as raw materials, obtaining alfalfa juice through processes such as washing, cutting, beating, and filtering; extracting alfalfa leaf protein by acid-heating method; preparing alfalfa leaf protein peptide powder by enzymatically hydrolyzing alfalfa leaf protein; The peptide powder is mixed with concentrated apple juice, white sugar, citric acid, β-cyclodextrin, compound stabilizer, drinking water, etc. to obtain the alfalfa leaf protein peptide beverage. The beverage is calculated in parts by mass, including 5-10 parts of alfalfa leaf protein peptide powder, 10-20 parts of concentrated fruit juice, 5-10 parts of white sugar, 1-5 parts of sour agent, 0.2-0.5 parts of β-cyclodextrin, compound 0.1-0.5 part of stabilizer, 0.05-0.1 part of sucrose fatty acid ester, and the balance is drinking water. The preparation method of the beverage provided by the present invention uses low-molecular-weight, easily absorbed alfalfa leaf protein peptide as the protein source, supplemented with concentrated fruit juice and other food additives, not only contains various nutrients such as protein and sugar, but also contains A variety of bioactive ingredients with health functions. Therefore, the alfalfa leaf protein peptide beverage provided by the present invention has excellent taste and flavor, is rich in nutrition, and has multiple physiological functions such as anti-aging, enhancing body immunity, and promoting digestion and absorption, and is suitable for drinking by various groups of people. The invention has simple process, mild conditions, low energy consumption, short production cycle, high peptide yield and strong operability, and is suitable for large-scale industrial production.
