The invention provides a method for increasing the panicle yield of a cuttage mother plant of Pinus massoniana, which comprises the steps of selection of the mother plant, planting of the mother plant, pruning and shaping, and management and protection of the mother plant. The tissue-cultured seedlings are used as the mother plant, and the tissue-cultured seedlings of Pinus massoniana are initially planted in a seedling container equipped with a seedling substrate, and then managed after the initial planting, and then the mother plant is truncated, and the planting is carried out on the prepared seedbed and after planting Management, when the buds of the mother plant grow to 5-6 cm long, the mother plant will be pruned and shaped, and at the same time, five aspects of water management, nutrient management, soil management, disease and insect pest control and mother plant renewal will be carried out on the mother plant. Management and protection. The mother plant cultivated by the present invention has a high survival rate, luxuriant branches and leaves, strong stems, and very vigorous vegetative growth, which effectively prolongs the service life of the mother plant, greatly improves the yield, quality and activity of spikes, and improves the rooting rate and survival of cuttings. The efficiency and quality of seedlings have improved the breeding effect of masson pine asexual seedlings.

The invention priovidese a new Broussonetia papyrifera mulberry tree hybrid distant hybridization and polyploidization breeding method. The method is characterized in that an inductive hybrid fruit callus doubling distant hybridization polyploid hybrid line is established by an embryo engineering and tissue culture technique of distant hybrids through a reproduction engineering kind improvement technology. The method comprises following steps: 1, obtaining distant hybrid fruits; 2, carrying out callus induction of the hybrid fruits; 3, carrying out colchicine treatment of the callus of the hybrid fruits; 4, carrying out recovery culture of treated calluses; 5, differentiating the calluses into bud seedlings; 6, differentiating the bud seedlings into roots; 7, transplanting tissue culture plants; 8, carrying out comparative observation and selection of survival plants; and 9, carrying out asexual propagation of the selected plants to form a stable kind (line). The method solves the problems comprising slow growth,weak adaptability, unclear trunk and bad material quality of present Broussonetia papyrifera, and allows the new polyploid Broussonetia papyrifera mulberry tree hybrid having the advantages of obvious trunk, strong adaptability and good material quality to be cultivated.

The invention discloses an efficient cultivation method of intercropping flue-cured tobacco and soybeans. The efficient cultivation method includes the following steps that (1) base fertilizer is applied in furrows before ridging in a tobacco field; (2) soil preparation and ridging are carried out on the tobacco field in good time; (3) the whole ridges are covered with a mulching film; (4) two rows of shaft well type transplanting holes are formed in the two sides of each ridge top, and two rows of crop planting holes are formed in the zone between the two rows of shaft well type transplanting holes; (5) flue-cured tobacco is transplanted in a shaft well mode, and tobacco plant transplanting position is located over the base fertilizer applied in furrows; (6) while the flue-cured tobacco is transplanted, soybeans are sown in a dibbled mode in the two rows of crop planting holes; (7) the flue-cured tobacco and the soybeans are managed through the normal method in the following steps. The influence on flue-cured tobacco growth by spring drought in the southwest region, the nicotine content of the flue-cured tobacco on the upper portion is reduced remarkably, the potassium content of the flue-cured tobacco on the upper portion is obviously increased, richness and diversity of rhizosphere soil bacterial communities of the tobacco plants are remarkably improved, flue-cured tobacco successive cropping obstacle is overcome, the income of peasants is increased additionally, and the efficient cultivation method is particularly suitable for the southwest region in China.

The invention relates to a high-yield planting method of coix lacryma-jobi as forage. The high-yield planting method of the coix lacryma-jobi as the forage comprises the following steps: (1) selecting land, weeding, applying base fertilizer, turning over, and carrying out soil preparation; (2) selecting seeds, drying the seeds in the sun, and intermittently soaking the seeds or carrying out seed dressing; (3) sowing, after seedlings emerge, weeding, thinning, thinning again, weeding, weeding again, and carrying out topdressing; (4) carrying out water and fertilizer management and pest control; and (5) cutting green plants, carrying out topdressing, irrigating, and covering stumps with straws after the last green plant cutting is finished, so that heat preservation is carried out, and early germination the next year is promoted. The high-yield planting method of the coix lacryma-jobi as the forage can be used for solving the technical problems that seasonal supply and demand of over-year living forage is unbalanced, summer forage is not resistant to waterlogging and slowly grows at high temperature and environmental requirement is high; biological yield of the coix lacryma-jobi is improved, yield per mu of fresh grasses reaches about 27 tons, on a land mass with fertility of the same class, the yield is increased by more than or equal to 130% compared with the summer forage zea mexicana, annual fresh grass production time is prolonged for more than or equal to 30 days compared with the zea mexicana, and the forage can be harvested for multiple years after sowing once; and the planted coix lacryma-jobi forage is high in yield and wide in application range.

The invention discloses a method for building a cutting orchard with Pinus massoniana Lamb. tissue culture seedlings. The method comprises the procedures of orchard selection, soil preparation, nursery stock preparation and field planting, annual management and cutting orchard management after field planting. The method comprises the following specific steps: selecting an orchard and performing soil preparation for later use; performing tissue culture on germinating robust Pinus massoniana Lamb. free from plant diseases and insect pests, and planting in a seed bed; after field planting, performing water and fertilizer management the same year; and performing fertilization and plant disease and insect pest prevention and control management on the cutting orchard to obtain scions which grow robustly and are super-vital, uniform in thicknesses and easy for cutting survival. The technical problems of poor cost of the current Pinus massoniana Lamb. tissue culture seedlings, poor rejuvenation function of stock plants in cutting rapid propagation, quick physiologic aging of the scions, poor vitality, difficulty for cutting survival and the like are solved. The method for building the cutting orchard with Pinus massoniana Lamb. tissue culture seedlings has the advantages of short stock plant culture period, high cutting survival rate, and good economical benefit, social benefit and ecological benefit.
