Restoration method for damaged ecosystem in steep-slope area in water-level-fluctuating zone of reservoir

The invention relates to a restoration method for a damaged ecosystem in a steep-slope area in a water-level-fluctuating zone of a reservoir. The method comprises the following steps:when the impounded water level is at the lowest point, cleaning the upstream slope in the water-level-fluctuating zone, and manually tamping; digging planting holes at the top of the slope, and planting Chinese red pines and the like to form a multifunctional protective forest belt; digging planting grooves and planting holes within the range of the water-level-fluctuating zone, laying jute geotextile, planting vetiver within the range with the water-level-fluctuating depth of 2m to form a hedgerow; and mixedly planting vetiver and wire grass within the range with the water-level-fluctuating depth of 2-10m to form a combined vegetation slope restoration belt. The protective forest belt, the hedgerow and the combined vegetation slope restoration belt form a three-dimensional restoration space together, thereby ensuring that plants can take roots and restore in the steep-slope area in the water-level-fluctuating zone. By restoring the vegetation in large area, the invention effectively reduces the overland flow and the soil erosion, and improves the fertility and the properties of the soil, thereby restoring the damaged ecosystem. The invention has the advantages of convenient construction and less investment, can not be easily damaged by water, and is applicable to the water-level-fluctuating zone of a reservoir with large water-level-fluctuating range and precipitous topography.

In addition, the bacteria strain D54 has the plant growth-promoting functions of producing plant growth hormone (IAA), producing 1-amino-1-carboxyl cyclopropane (ACC) deaminase, secreting siderophore, dissolving inorganic phosphate, fixing nitrogen and the like, has the biological prevention functions of antagonizing plant pathogenic bacteria inbreak and the like, and can obviously improve the biomass of the plants applied the invention and improve the resistance to diseases and stresses. The number of the effective viable bacteria in liquid preparation reaches 1-2 billion/ml and the number of the effective viable bacteria in solid preparation reaches 1 billion/g. Soaking seeds for 1-2 hours in the liquidpreparation which is diluted 100 times and irrigating the diluted liquid preparation 1-2 times (10ml/kg) after 2-3 weeks of the sprouting of the seeds can effectively improve plant viable bacteria infection probability.

Chicken manure fermentation organic fertilizer

The invention discloses a chicken manure fermentation organic fertilizer, which is prepared from the following raw materials: chicken manure, straw powders, konjak flour, corn flour, cellulose, zeolite, humic acid, potassium dihydrogen phosphate, urea, peat soil, a leavening agent, a soil improvement agent, a film coating agent, potassium sulfate, borax and calcium superphosphate. The above raw materials are subjected to the integrated treatment of anaerobic fermentation and aerobic fermentation, so that the organic fertilizer is prepared through the fermentation of the chicken manure. The chicken manure fermentation organic fertilizer is complete in fermentation effect, and is capable of killing plant pathogenic bacteria, eggs, weed seeds and other harmful microorganisms in the chicken manure, and generating a large amount of nutrients beneficial to the plant growth and the plant absorption. The process is simple and easy to implement. The raw materials of the prepared organic fertilizer are rich in nutrition. Meanwhile, the prepared organic fertilizer is high in fertilizer efficiency and rich in nutrition, and can coordinate the soil nutrient balance, improve the soil nutrient, promote the plant growth, increase the plant yield and improve the plant quality.

Method for efficiently and quickly producing bletilla striata seedling

The invention aims at providing a method for efficiently and quickly producing a bletilla striata seedling. The method comprises (1) a liquid culture stage and (2) a solid medium culture stage, wherein (1) the liquid culture stage comprises the particular steps that a bletilla striata capsule is disinfected via sodium hypochlorite; the capsule is cut; a seed is sown in a liquid medium for culture; the seed is developed into a protocorm; (2) the solid medium culture stage comprises the particular steps that the protocorm is induced to be differentiated into a root-free seedling, and then transferred to a rooting culture medium for rooting culture, and a cultivation substrate transplanted into a greenhouse is domesticated before field transplanting. The method realizes efficient and quick production of the bletilla striata seedling; compared with whole-course solid culture, the method overcomes the defect that the seed germination rate is low when an early seed is cultured on a solid medium; the seed germination rate is increased significantly and reaches 99%; the fresh weight and the dry weight of the protocorm are increased greatly; and the whole production cycle is shortened significantly, and can be shortened to about 110 days.
