Seed-dressing agent for pelleted herbaceous plant seeds in falling zone of reservoir area and pelleting technique

Abstract

The invention discloses a grass seed pelleting seed coating agent for planting grassland vegetation of falling zones of reservoir areas, which comprises a water-absorbing resin, a compounding active constituents which synergetically promote the germination of grass seeds and strengthen the capabilities of the drought resistance and the growth of grass, and an inert constituent which can supplement the soil defect of the falling zones of the reservoir areas and strengthen the weight of the grass seeds, wherein the compounding active constituent consists of 5 to 10 mass portions of furfuraldehyde derivative, 0.1 to 0.25 mass portion of gibberellin, and 89 to 95 mass portions of sodium humate. The seed coating agent orderly contains 5 to 20 mass portions of the water-absorbing resin, 5 to 10 mass portions of the gibberellin, and 70 to 90 mass portions of the sodium humate. The invention also discloses a pelleting technology and a pelleted outer-layer constituent with functions of water absorption and adhesion when encountering water. The invention overcomes the defects of steep terrain, barren soil, poor water retention property, as well as difficult ground adhesion and difficult germination and growth of sown grass seeds that the plantation of the grassland vegetation of the falling zones of the reservoir areas faces, also applies the furfuraldehyde derivative to the seed pelleting seed coating agent, and reduces the effective using concentration of the gibberellin to between 0.6 and 1.5ppm.

Description

technical field [0001] This patent belongs to the technical field of vegetation reconstruction engineering in the water-fluctuation zone of the reservoir area, and relates to the planting technology of herbal plants in the water-fluctuation zone of the reservoir area, especially the pill-coated seed coating agent and the pill-coated technology of the herbal plant seeds in the water-fluctuation zone of the reservoir area. Background technique [0002] The water-fluctuation zone of the reservoir area refers to a special area where the land around the reservoir is submerged or exposed to the water due to seasonal water level fluctuations. There are tens of thousands of reservoirs in the mainland of my country. In order to ensure the water collection function of the reservoirs during the flood season and the water storage function after the flood season, most of the reservoirs must carry out the operation of "cleaning and discharging turbidity" every year. During the operation p...

AI Technical Summary

Problems solved by technology

Although the polymer water-absorbing agent and humic acid can form several tiny reservoirs around the seeds, which have the function of storing water and releasing water slowly, in the area of ​​the water-fluctuating zone of the reservoir area, the soil content is small, the slope is large, and the rainwater is lost Fast, these potential tiny reservoirs may not get enough water, so relying solely on water-absorbing agents cannot fundamentally solve the problem of herb seed germination and growth

In addition, compared with ordinary grassland pastures, the land-forming period of the water-fluctuating zone in the reservoir area is limited (between the end of May and the end of September), and the plant growth period is relatively short. The need to germinate and complete the growth cycle as quickly as possible within the

In the past, the patents related to the restoration of herbaceous vegetation in the water-fluctuation zone of the reservoir area only involved the selection of a single grass species (CN1990959) and the slope protection components of the water-fluctuation zone in the reservoir area (CN1837508, CN2887959). The loss of biodiversity in the water-fluctuation zone of the reservoir area and the improvement of the economic benefits of planting in the water-fluctuation zone of the reservoir area, and the construction of slope protection components in the water-fluctuation zone of the reservoir area require a large amount of investment, which is not good for the huge area of ​​the water-fluctuation zone in my country. realistic
