Embodiment 1

[0036] A kind of cultivation method of No. 5 Jinyincao, the method comprises the following steps:

[0037] (1) Emphasis on cultivating the root system of the parents to improve the adaptability (May 94-May 97, location: the location of Bamao Township, Luodian County). Dian as a breeding base; the root stimulating solution was used to soak for 1 minute in the seedling stage of the parent African wild pennisetum and elephant grass; the preparation of the root stimulating solution was as follows: 300 mg of naphthalene acetic acid; 300 mg of indole butyric acid; 2,4- Add 2 mg of dichlorophenoxyacetic acid to dissolve in 98% alcohol and add 1000 ml of water; then add 2000 mg of potassium dihydrogen phosphate and 5 mg of boric acid into the water to fully dissolve. Use root stimulating liquid to stimulate it to make it take root quickly, make the root stronger and the root system more developed, so that it is easy to absorb nutrients and grow faster; when the seedling grows to 20cm,...

Embodiment 2

[0052] A kind of cultivation method of No. 5 Jinyincao, the method comprises the following steps:

[0053] (1) Emphasis on cultivating the root system of the parents to improve the adaptability (May 94-May 97, location: the location of Bamao Township, Luodian County). Dian as a breeding base; the root stimulating solution was used to soak for 1 minute at the seedling stage of the parent African wild pennisetum and elephant grass; the preparation of the root stimulating solution was as follows: 350 mg of naphthalene acetic acid; 350 mg of indole butyric acid; 2,4- Add 3 mg of dichlorophenoxyacetic acid to dissolve in 98% alcohol and add 1000 ml of water; then add 2000 mg of potassium dihydrogen phosphate and 5 mg of boric acid into the water to fully dissolve. Use root stimulating liquid to stimulate it to make it take root quickly, make the root stronger and the root system more developed, so that it is easy to absorb nutrients and grow faster; when the seedling grows to 20cm,...

Embodiment 3

[0058] A kind of cultivation method of No. 5 Jinyincao, the method comprises the following steps:

[0059] (1) Emphasis on cultivating the root system of the parents to improve the adaptability (May 94-May 97, location: the location of Bamao Township, Luodian County). Dian as a breeding base; the root stimulating solution was used to soak for 1 minute in the seedling stage of the parent African wild pennisetum and elephant grass; the preparation of the root stimulating solution was as follows: 400 mg of naphthalene acetic acid; 400 mg of indole butyric acid; 2,4- Add 5 mg of dichlorophenoxyacetic acid to dissolve in 98% alcohol and add 1000 ml of water; then add 2000 mg of potassium dihydrogen phosphate and 5 mg of boric acid into the water to fully dissolve.

Abstract

The invention discloses a method for cultivating acclimatized pennisetum alopecuroides 5#. The method comprises the following steps: (1) cultivating parent strong root systems; (2) carrying out parent hybridized combination; (3) acclimatizing resistance characteristic of the acclimatized pennisetum alopecuroides 5#; and (4) acclimatizing progressive type cold resistance characteristic of the acclimatized pennisetum alopecuroides 5#, wherein the parent hybridized combination in the step (2) means carrying out combination cultivation by adopting a back-cross method in a manner of taking napier grass as a paternal parent and taking African pennisetum alopecuroides as a maternal plant. The acclimatized pennisetum alopecuroides 5# planted by adopting the method for cultivating the acclimatized pennisetum alopecuroides 5#, disclosed by the invention, completely has the characteristics, i.e., special barren resistance, drought resistance, moisture resistance and high-temperature resistance of acclimatized pennisetum alopecuroides 2#, meanwhile, the growth speed is higher, the yield is higher, and the nutrients are richer.

Description

technical field [0001] The invention relates to the field of grass planting, in particular to a method for cultivating No. 5 Jinyincao. Background technique [0002] Elephant grass and hybrid pennisetum (also known as Huangzhu grass) belong to the angiosperm, monocot class, grass family, Pennisetum genus plants, the current situation is as follows: elephant grass, a large perennial herb with a well-developed fibrous root system, It is mostly distributed in the 40cm soil layer, and the division is strong. The general plant height is 2-3.5m. It likes warm and humid climate. It starts to grow when the average daily temperature is 15°C, and the growth speeds up when the temperature reaches above 20°C. When the temperature drops to 10°C Longevity is blocked when the temperature is below 5°C, and it will stop growing when it is below 5°C, and it will die at -1°C; this variety has no strict requirements on the soil, is drought-tolerant, relatively humidity-resistant, and has good a...
