Greening method for increasing plant diversity by simulating natural plant community

InactiveCN102067770BIncrease biodiversityHigh amount of greenHorticulturePlant communityGreening
The invention belongs to a forest, greening and ecological restoration field and relates to a greening method for increasing plant diversity by simulating a natural plant community. The method comprises steps of: investigating the present situation and history of natural and local plant communities in a city or an area; evaluating and selecting natural and local plant communities; optimizing the selected natural and local plant communities; breeding seedlings of the natural and local plants; applying greening projects which simulate the natural and local plant communities; and subsequently optimizing and evaluating simulative natural and local plant communities and the projects. Utilizing the multi-layer plant community characteristics (multi-layer, multi-structure, multi-function) of the natural and local plant communities, the invention establishes close-natural plant communities which can fully utilize space resources, adapt to local environments and form stable and long-term coexistence; the invention can achieve a large green quantity per unit space, good ecological benefits and powerful ecological functions, substantially increase biological diversity of urban greenland, improve landscape functions, show regional characteristics and reduce maintenance costs.

InactiveCN104957385ADetermine the fermentation conditionsFully digestedFood processingAnimal feeding stuffHazardous substanceDigestion
The present invention discloses a salix psammophila mixed fermented feed composition and a preparation process and a feeding method thereof. The feed is prepared from the following components in parts by weight: salix psammophila 30-70, corn 3-20, molasses 2-10, mixed grass 2-8, 0.2% premix 0.1-2, salt 0.2-0.8 and bacterium preparation 0.1-0.5; and the components can also further include wheat bran 8-25, urea 0.01-1.5, potato dregs 3-15 or stone powder 0.2-0.6. The preparation process includes: mowing and stumping the salix psammophila; cutting and processing the salix psammophila; rubbing and grinding the salix psammophila into filiform raw materials; mixing the raw materials with other components, adding broth and water into the mixture; checking water contents, stirring the mixture evenly; and packaging and storing the feed for 7-10 days for feeding. The feed solves the difficult problem of the application of the salix psammophila in the field of animal husbandry, and the feed not only effectively improves digestion rate, utilization rate, conversion rate and palatability of the salix psammophila, but also significantly improves feed palatability by using a role of microorganisms in decomposing harmful tannin substances of the salix psammophila. The feed can be used to feed cattle, sheep and other ruminants with significant effects in increasing production and improving meat and milk quality.
