Embodiment 1

[0030] Example 1 A method for improving the success rate of forage grass planting in erosion ditch in black soil area

[0031] The method comprises the steps of:

[0032] Step one, seed treatment

[0033] Seed selection: The selected species of brome without awns should be suitable for growth in Heilongjiang area, have strong cold resistance, and the overwintering rate is above 90%. For alfalfa, choose Longyin Beza87 alfalfa, which is more suitable for the growth of erosion ditch. This variety is suitable for the geographical environment requirements of erosion ditch, and has the advantages of resistance to barrenness, cold, and drought;

[0034] Seed treatment: Alfalfa hard seeds can be treated with a rice mill until the seed coat becomes hairy. Alfalfa can be seed-dressed with 6.5% phenanthrenequinone by seed weight to prevent alfalfa ring spot; 0.3% phenanthrenequinone and thiram can be seed-dressed by seed weight for awnless brome to prevent and control smut and hard smu...

[0047] The method comprises the steps of:

[0048] Step one, seed treatment

[0049] Seed selection: The selected species of brome without awns should be suitable for growth in Heilongjiang area, have strong cold resistance, and the overwintering rate is above 90%. For alfalfa, choose Longyin Beza87 alfalfa, which is more suitable for the growth of erosion ditch. This variety is suitable for the geographical environment requirements of erosion ditch, and has the advantages of resistance to barrenness, cold, and drought;

[0050] Seed treatment: Alfalfa hard seeds can be treated with a rice mill until the seed coat becomes hairy. Alfalfa can be seed-dressed with 6.5% phenanthrenequinone by seed weight to prevent alfalfa ring spot; 0.3% phenanthrenequinone and thiram can be seed-dressed by seed weight for awnless brome to prevent and control smut and hard ...

Abstract

The invention discloses a method for improving the success rate of planting forage grass in an erosion ditch in a black soil area, and particularly relates to the field of forage grass planting. The method comprises the steps of seed treatment, terrain selection, sowing, field management and harvesting utilization. The characteristics of the alfalfa and the awnless brome are utilized, the two kinds of forage grass seeds are planted in a mixed mode, the yield of the two kinds of forage grass can be greatly increased, the environment of the erosion gully of the black soil area in the northeast can be improved, and the soil fixation and slope protection effects of mixed sowing of the alfalfa and the awnless brome are more remarkable.

Description

technical field [0001] The invention relates to the field of grass planting, in particular to a method for improving the success rate of forage grass planting in erosion ditches in black soil areas. Background technique [0002] Although the black soil area in Northeast China has only been developed for more than a hundred years, due to high-intensity predatory management, serious soil erosion has occurred, which is specifically manifested in the thinning of the fertile black soil surface and the vertical and horizontal gullies, the reduction of the black soil area, and the decline in quality. As the most serious manifestation of land degradation, gully erosion is very serious. According to the first national water conservancy census, there are 296,000 eroded ditches with a length of more than 100m in the black soil region of Northeast China. There are about the same number of incised ditches less than 100m in length, so the total number of eroded ditches in the black soil r...
