Ecological restoration method for lakeside wetland

The invention discloses an ecological restoration method for a lakeside wetland. In the method, hygrophilous woody plants are planted in a lakeside zone to construct wetland plant communities. The hygrophilous woody plants comprise hygrophilous arbor and hygrophilous shrub, wherein the hygrophilous arbor comprises willows, metasequoia, ascendens mucronatum, taxodium ascendens brongn and bamboo; the hygrophilous shrub comprises iteaceae and S.integra thrnb; and the plants are planted in the way of shoot cottage or soil ball transplant. The hygrophilous woody plants are perennial plants, have a low growth rate, low biomass, low growth amount and low plant disposal pressure and do not need felling and refloating every year, so that the defects of frequently harvesting and refloating herbal emergent aquatic plant communities every year are overcome, the maintenance and management cost of lake wetland plant communities are reduced, the lakeside depositing rate is lowered, and the secondary pollution hidden danger to lake water bodies is relieved. Compared with the prior art, the method has the characteristics of convenient operation, maintenance and management, low maintenance cost, high ecological benefit, easy popularization and application and the like and can be used for ecological restoration engineering of lake and lakeside bottomlands, swamp marshes and shallow water zones.

Hybrid seed production method for forage maize

The invention discloses a hybrid seed production method for forage maize. In the method, teosinte serves as a male parent and maize tri-crossed hybrid serves as a female parent to produce a forage maize SC2 seed in a hybrid way. The hybrid production comprises the following steps of: 1) sowing the male parents and the female parents at time intervals to obtain the male parents having blossom intervals and the female parents having the blossom intervals; 2) performing hormone spraying and tassel removal on the female parents having the blossom intervals obtained in the step 1) to obtain the tassel-removed female parents having lower plant heights and lower ear heights; 3) trimming the subtending leaves of the tassel-removed female parents having the lower plant heights and the lower ear heights obtained in step 2) to obtain un-pollinated female parents; and 4) collecting the pollen of the male parents having the blossom intervals obtained in the step 1), pollinating the un-pollinated female parents obtained in the step 3) by using the pollen and culturing the pollinated female parents to obtain the forage corn SC2 seeds. Experiments of the invention show that plant obtained by planting the forage maize SC2 seed obtained by the method of the invention is gramineous pasture having high quality.

Production method of SOD selenium-enriched rice

The invention discloses a production method of SOD selenium-enriched rice. The production method comprises the following steps: seed soaking, germination acceleration, seedling cultivation and rice seedling transplanting; during germination acceleration, a superoxide dismutase solution is prepared from water and lauric-acid-modified superoxide dismutase in the weight ratio of (100-300g):1g, and then, the superoxide dismutase solution is sprayed on seeds in a germination acceleration period according to the weight ratio of (100-300g):(7-7.5kg); during seedling cultivation, the superoxide dismutase solution is sprayed on rice seedlings corresponding to the seeds according to the weight ratio of (100-300g):(7-7.5kg); after rice seedling transplanting is finished, a Bacillus solution is prepared from Bacillus and water in the weight ratio of (45-50g):25kg and is mixed with 100ml of liquid selenium fertilizer in a selenate complex form to obtain an SOD selenium-enriched solution, and 20-30kg of SOD selenium-enriched solution is sprayed on leaf surfaces of per mu of rice respectively in a heading period, a flowering period and a filling period. By using the method disclosed by the invention, the problems of high selenium content in plants and low plant yield are solved, the rice is made to be rich in selenium and SOD, and the yield is increased.

Method for assistantly sieving soybean with lower plant height and special primer thereof

The invention discloses a method for assistantly sieving soybean with lower plant height trait and a special primer thereof. The method comprises the following steps: the genomic DNA of soybean to betested is adopted as a template, the primer is used for carrying out PCR amplification on a party A and a party B respectively and an amplified product of the soybean to be tested is obtained; the genomic DNA of Charleston is adopted as a template, the primer is used for carrying out PCR amplification on the party A and the party B respectively and an amplified product of the Charleston is obtained; carrying out electrophoresis on the amplified products of the soybean to be tested and the Charleston, if presenting same band type, the soybean to be tested is candidate soybean with lower plant height trait; a primer pair A consists of nucleotides shown in a sequence 1 of a sequence table and a sequence 2 of the sequence table; and a primer pair B consists of nucleotides shown in a sequence 3of the sequence table and a sequence 4 of the sequence table. The invention also provides a quantitative trait locus of the soybean with height plant, which is positioned at an L linkage group and ispositioned between Sat_009 and Sat113 of the SSR primer locus. The method can judge whether the quantitative trait locus (QTL)-htL_1 is contained by DNA measurement of soybean variety resource or filial generation, thus predicting the plant height level of the soybean and accelerating and improving breeding speed of the plant height of the soybean.

Peanut somatic embryo induction and plant regeneration method

The invention provides a peanut somatic embryo induction and plant regeneration method, which can solve the problem of low plant regeneration frequency in the prior art. The method of the invention comprises the following main steps: separating embryonic leaflet from a peanut embryo which is treated by surface sterilization and soaked, and inoculating the embryonic leaflet to an induction culture medium to which 2,4-D (5-10mg/L) is added for culturing a somatic embryo; then transferring the somatic embryo to a somatic embryo germinating culture medium to which BAP (4mg/L) is added, and subculturing twice to obtain regenerated plants; and cutting the somatic embryo at the bottom after the somatic embryo germinates and elongates, and transferring the cut somatic embryo to a 1/2MS inorganic salt and B5 organic rooting culture medium to which NAA (0.2-0.5mg/L) is added for inducing rooting to obtain complete plants. By taking the embryonic leaflet of peanut mature seeds as explant, and using the induction culture medium of 2,4-D (5-10mg/L) and the somatic embryo germinating culture medium of BAP (4mg/L), the somatic embryo induction rate and plant regeneration rate are high, and simultaneously the somatic embryo is derived from one cell, and the chimerism of regenerated plants is avoided.
