A method for in vitro preservation of anthurium germplasm resources, using the thick sucking buds of anthurium after removing leaves as explants, washing them under tap water, disinfecting the surface of the explants with 72-75% alcohol, and using Rinse once with sterile water, treat with 0.1% mercuric chloride, rinse three times with sterile water, blot dry with sterile filter paper; then cut the explants into segmented stem segments and inoculate them into bud induction medium for culture After 45 days, transfer the germinated axillary buds to the proliferation medium to obtain clustered seedlings for 40 days; divide the obtained clustered shoots into individual plants and transfer them to the in vitro preservation medium for preservation; in vitro preservation culture Base: White+0.1~0.2g / LC 6 h 5 Na 3 o 7 +30g / L sucrose+5g / L agar powder. The method of the present invention preserves the Anthurium test-tube seedlings for 16 months, the botanical traits and RAPD amplification bands of the progeny will not be different, the preservation material is stable, no genetic variation will occur, and the species degradation and virus infection can be prevented, and the species quality can be guaranteed. Excellent quality characteristics.

The invention discloses a method for measuring the stress state of plant water, which comprises the following steps: S1: determinating the scanned range and the sampling point of the plant to be measured and constructing an x y rectangular coordinate system within the determinated scanned range; S2: acquiring a height value d x y of the sampling point in the scanned range; S3: setting a height threshold D, combing the height value d x y of the sampling point, and extracting the sampling point positioned on the leaf of the plant to be measured; S4: reconstructing a three-dimensional space shape and calculating the three parameters of the average height h0 of the leaf, the inclination angle Alpha of the leaf and the area of the leaf s0 on the basis of combing the x y coordinate system constructed in the S1 and the height value of the extracted sampling point positioned on the leaf of the plant in the S3; and S5: according to the three parameters of the average height h0 of the leaf, theinclination angle Alpha of the leaf and the area of the leaf s0, and floristics to be measured, judging the water loss of the current plant. The invention can directly measure plant morphological characteristics, and has simple operation process, low degree of operation difficulty and the effect of small measurement error.

The invention relates to a breeding method of hybrid cabbage, in particular to a simplified breeding method for preparing hybrid cabbage by using cytoplasmic male sterile lines, which belongs to the technical field of plant culture. The invention directly adopts the cabbage varieties of Zhonggan No.22 and Hugan No.2 prepared by cytoplasmic male sterile lines sold in the market as maternal plants,and adopts cabbage inbred lines (with the same ball shape as the maternal plants, the same type of leaf ball mature performance as the maternal plants and stable botanical characters) as pollen suppliers for preparing good coenospecies. The invention has the advantages that when the advantages of using the cytoplasmic male sterile lines for preparing the cabbage coenospecies are maintained, good cabbage inbred lines do not need to be used as recurrent parents for fifth to seventh generation backcrossing and transformation with male sterilant materials, the labor is saved, the cost is saved, the breeding time is greatly shortened, and in addition, the hybrid vigour parts of the original varieties can be maintained into the new hybrid varieties.

The invention belongs to the field of botany, and relates to a plant powder fixed-point quantitative sprayer, which includes a spray rod and a medicine bottle. The other end of the conduit is connected with the medicament bottle, and the medicament bottle is also connected with the high-pressure gas delivery device through the pressure conduit. The invention has simple structure and high practicability, can spray powder at fixed points and quantitatively on plants, especially high-stem crops such as betel nut, solves the problem that the powder cannot be accurately applied to the target site in the process of powder application, reduces the loss of powder, and improves the efficiency of powder. It is especially suitable for the control of diseases and insect pests, which is conducive to improving the control effect and achieving the effect of "reducing application and increasing efficiency" in the process of powder application.

The invention relates to the botany field, in particular to a method for extracting juice in a vascular bundle of a plant leaf with stems, comprising the following steps of: circularly cutting along 0.5 to 1cm of the outer margin of the leaf by a clean and sharp blade to open the vascular bundle of the leaf margin; retaining 3 to 8cm of the stem, and removing the superfluous stems by the blade; semi-circularly cutting the position which is between 0.5 and 1cm from the end part of the stem, and removing the sieve vessel part; putting the processed plant leaf into a depression box, leaving the stem outside the depression box, pressurizing the depression box to enable juice in the sieve vessel of the leaf to flow out from a cut of the stem, and collecting the juice flowing out from the cut of the sieve vessel. The method has the advantages of wide application range, large acquisition of samples, no pollution of samples and more accurate test result.

The invention discloses a method for making a high-emulation medicinal plant specimen. The method comprises the steps of medicinal plant analyzing, basic mold making, medicinal plant organ simulation specimen making and medicinal plant organ combination. The method for making a high-emulation medicinal plant specimen is suitable for experimental teaching of 'Botany' and 'Medicinal Botany' and display of a specimen room. Users can observe morphological features of different organs of a medicinal plant such as root, stem, leaf, flower and fruit in a specimen room without carrying out collection, dissection or other related processing, which makes up for the defect that the plant source is affected by geographical and seasonal restrictions in the teaching process of Medicinal Botany. Different organs of a high-emulation medicinal plant specimen can be disassembled and assembled, and users can compare the same organs of different medicinal plants to quickly grasp the key points for differentiation of medicinal plants. In addition, display of medicinal organs with the use of high-emulation medicinal plant specimens provides a basis for traditional Chinese medicine identification in 'Science of Identification of Traditional Chinese Medicine'.

The invention belongs to the field of botany, and particularly relates to an early evaluating method for tea tree winter resistance. The soluble sugar (mainly cane sugar) content is one important physiological basis for the strength of the tea tree winter resistance and one important presentation of the low temperature adaptability of the tea tree variety; and as the temperature is gradually lowered with the approaching of the winter, the cane sugar content of the tea tree leaves is gradually increased, however the tea tree variety with high winter resistance has higher-increased cane sugar content than the tea tree variety with low winter resistance. The early evaluating method for the tea tree winter resistance evaluates the winter resistance of the tea tree by measuring the cane sugar content in the tee tree leaves, so as to evaluate and select the tee tree variety with high winter resistance and provide basis for variety introduction for the tea tree.
