Description
Technical field
The present invention relates to pasture growing technical field, the breeding method of specifically a kind of herbage.
Background technique
Herbage refers generally to the grass used for the livestock of raising or other herbaceous plant.It is not only required containing domestic animal in herbage
Various nutriments, also containing to the especially important crude fibre of ruminant domestic animal health is maintained, this is grain and other feed institutes
It is irreplaceable.Good forage grass can satisfy the nutritional need of general domestic animal completely, if not in production or fattening period, one
As need not be supplemented fine fodder.It is many experiments have shown that, if the quality of forage grass is too low, no matter supplement how many fine fodder, the milk yield of ox
It is all on a declining curve, however the forage plants breeding level in China itself is also lower at present, the herbage product quality of incubation is not high, agronomy
The production traits is undesirable, far from meeting the needs of production, then the herbage planted using traditional breeding method, low output,
It is of poor quality, leaf amount is small, stalk is harder, palatability is poor.Therefore, it is necessary to a kind of breeding method of herbage that can improve forage yield,
The forage yield cultivated is high, leaf amount is big, stalk is more crisp, and palatability is good.
Summary of the invention
A kind of breeding method of herbage provided by the invention, the forage yield height of the grass seed plantation after breeding, quality
Height, leaf amount is more, stalk is more crisp, palatability is good, moreover it is possible to which plantation is provided with the sugar grass that the mankind eat, and not only meets the need of animal
It asks, while ensure that food for the survival of mankind, improve breeding efficiency.
The object of the present invention is to provide a kind of breeding methods of herbage, comprising the following steps:
S1 selects the grass seed of full grains, free from insect pests to plant, and basks seeds, and grass seed is pressed spacing in the rows 50-70
Centimetre, 1.5-3 meters of line-spacing are seeded into soft soil；
S2 sows a line sweet sorghum seed, in the sweet sorghum seed described in every row between two adjacent row grass seeds
The spacing of adjacent sweet sorghum seed is 40-60 centimetres；
S3 grasps flowering time, guarantees that the flowering time of herbage is consistent with the flowering time of sugar grass by field management,
It allows the pollen of sugar grass floatd naturally onto the flower spike of herbage, forms spontaneous pollination；
S4 obtains first generation hybridization grass seed later to the herbage florescence, the first generation of full grains is selected to hybridize herbage
Seed is spare；
First generation hybridization grass seed is seeded into soft soil according to implantation methods described in S1 and obtains first by S5
Generation hybridization herbage；
S6, according to implantation methods described in S2, sowing a line sweet tea is high between adjacent two row first generation hybridization grass seed
Fine strain of millet seed；Then flowering time is grasped, guarantees that the first generation hybridizes the flowering time of herbage and opening for sugar grass by field management
It takes time consistent, allows the pollen of sugar grass floatd naturally onto the flower spike of first generation hybridization herbage, form spontaneous pollination；
S7 obtains second generation hybridization grass seed later to the herbage florescence, the second generation of full grains is selected to hybridize herbage
Seed is spare；
Second generation hybridization grass seed is seeded into be obtained in soft soil herd according to implantation methods described in S1 by S8
Grass completes the breeding of herbage；
Wherein, the field management includes the fertilising of herbage cradled with herbage and sugar grass, guarantees blooming for herbage
Time is consistent with the flowering time of sugar grass, and the height of herbage and the height of sugar grass will be also consistent, conducive to sugar grass
Pollen is floatd naturally onto the flower spike of herbage, forms natural hybridization pollination.
Preferably, the grass seed be ryegrass seed, purity >=95% of the grass seed and sweet sorghum seed,
It is selected to carry out progress before broadcasting palpus, germination percentage is 90% or more, and to guarantee to emerge after broadcasting neatly, growth of seedling is healthy and strong.
Preferably, the implantation time of the grass seed is selected in late February of the lunar calendar between late March, the sweet tea
The sowing time of sorghum seeds is selected in the late May of the lunar calendar between late June.
Preferably, it after grass seed emergence, to be cut weeds in time and thinning, and when the grass seed is sowed
Obtained herbage is applied fertilizer after growing to 20 cm heights or more, can be cradled one or two moon once, and each plane earth cradles,
It cradles every time latter 7-10 days, to top dressing 35kg-45kg per acre.
Preferably, the organic fertilizer that the fertilising and top dressing use cow dung, chicken manure, pig manure decomposed.
Compared with prior art, the breeding method of herbage provided by the invention, has the advantages that
A kind of breeding method of herbage of the invention can plant the sweet tea for being provided with the mankind and eating while carrying out forage plants breeding
Sorghum, not only meets the demand of animal, while ensure that food for the survival of mankind, the grass seed sowing after breeding
Obtained forage yield is high, leaf amount is big, stalk is more crisp, and the sugar content of stem is up to 5% or more, and animal palatability is good, crude protein
The nutritive values composition such as content, crude fat, crude fibre is big, can directly feed and not need additive, and animal system can be improved, and increases
Strong immunity can prevent and treat common disease and epidemic virus.
