Problems solved by technology

[0004] Hybrid pennisetum (also known as emperor bamboo grass, which is bred by hybridization of American pennisetum and elephant grass) is a large perennial herb with well-developed fibrous roots, mainly distributed in the 20cm soil layer, with strong divisions, and the height of the plant is 3-4m , like warm and humid climate, it starts to grow when the average daily temperature reaches 15°C, accelerates when the temperature reaches above 20°C, hinders growth when the temperature rises below 10°C, stops growing when the temperature is below 5°C, and dies at 0°C; The soil requirements are not strict, drought tolerance, slight humidity tolerance, and poor adaptability; the crude protein content of the hay is 9.95%, and the annual output of fresh grass is 130 tons to 160 tons / ha. The shortcomings of this variety are not water resistant, not cold resistant, poor palatability, and small growing area
[0005] The above two grasses have certain limitations in use due to their own characteristics, so they cannot be used in some harsh environmental conditions.

Embodiment 1

[0029] A method for cultivating high tolerance Jinyincao No. 2, comprising the steps of:

[0030] (1) The parents focused on cultivating the parental root system and improving their adaptability (May 94-May 97, location: Bamao Township, Luodian County) The introduced species was first introduced in Xishuangbanna, which is known as Guichuan's natural greenhouse. Luodianpi was used as a breeding base; the parent African pennisetum and elephant grass were first planted in the soil of the paddy field, grown for one year under the condition of sufficient water and fertilizer, transplanted in the soil of gravel soil for planting in the second year, and planted in the third year. It was transplanted in barren sandy soil and planted in barren sandy soil, and finally transplanted in paddy field for one year of cultivation. The results show that the root system of the grass planted in this way is well developed, and most of them are distributed in the soil layer of 60-80 cm. The adaptab...

Embodiment 2

[0045] A method for cultivating high tolerance Jinyincao No. 2, comprising the steps of:

[0046] (1) The step of cultivating the strong root system of the parent, planting the parent African wild pennisetum and elephant grass in the soil of the paddy field first, growing for one year under the condition of sufficient water and fertilizer, and transplanting in the soil of gravel soil for planting in the second year, In the third year, it was transplanted to barren sandy soil for planting, and finally it was transplanted to the paddy field for one year of cultivation.

[0047] (2) Combination of parents; hybridization of parents cultivated with strong roots by conventional hybridization methods;

[0048] The first step is to select the flower spikes of the male parent (African wild Pennisetum) with well-developed root system, strong tillering ability, tall plants, and complete cylindrical panicles. It is carried out at 8:30 in the morning on a sunny day. Cut off the flower spik...

Embodiment 3

[0061] A method for cultivating high tolerance Jinyincao No. 2, comprising the steps of:

[0062] (1) The step of cultivating the strong root system of the parent, planting the parent African wild pennisetum and elephant grass in the soil of the paddy field first, growing for one year under the condition of sufficient water and fertilizer, and transplanting in the soil of gravel soil for planting in the second year, In the third year, it was transplanted to barren sandy soil for planting, and finally it was transplanted to the paddy field for one year of cultivation.

[0063] (2) Combination of parents; hybridization of parents cultivated with strong roots by conventional hybridization methods;

[0064] The first step is to select the flower spikes of the male parent (African wild Pennisetum) with well-developed root system, strong tillering ability, tall plants, and complete cylindrical panicles. It is carried out at 9:30 in the morning on a sunny day. Cut off the flower spik...

Abstract

The invention relates to the technical field of pasture resource utilization, in particular to a method for cultivating honeysuckle flower number 2. The method includes: (1) cultivating parent strong roots; (2) hybridizing and combining parents; (3) domesticating resistance of the honeysuckle flower number 2 progressively; (4) domesticating cold resistance of the honeysuckle flower number 2 progressively. The cultivated honeysuckle flower number 2 cultivated by the method has the advantages of (1) wide growing area, (2) tolerance to barren soil, (3) tolerance to draught, wet and high temperature, (4) rich roots, strong tillering capability, (5) relative resistance to low temperature, (6) high plants, growing speed and output, and (7) rich nutrients including amino acid and micronutrient, crude protein content of fresh honeysuckle flower number 2 reaches to 8.21%, equivalently the crude protein content of the dry honeysuckle flower number 2 reaches to 10.6%, the crude protein content is one percent point more than that of rice, both beasts and birds love to eat, and the honeysuckle flower number 2 is a great grass variety with multiple functions.

Description

technical field [0001] The invention relates to the technical field of forage resource utilization, in particular to a method for cultivating No. 2 Jinyincao. Background technique [0002] Elephant grass and hybrid pennisetum (also known as Huangzhu grass) belong to the phylum of angiosperms, the class of monocots, the class of grasses, and the genus of Pennisetum. The current status is as follows: [0003] Elephant grass, a large perennial herb with a well-developed fibrous root system, is mostly distributed in the 40cm soil layer, and has strong divisions. The general plant height is 2-3.5m, and it likes warm and humid climates. Growth is accelerated when the temperature is above 20°C, long-term growth is hindered when the temperature drops below 10°C, growth stops when the temperature is below 5°C, and death occurs when the temperature is -1°C; this variety has no strict requirements on the soil, is drought-tolerant, relatively humidity-resistant, and has good adaptabilit...
