Greatly, grain demand amount is big, but per capita cultivated land is few.Although total output of grain realizes 10 years excellent situations even increased, people and animals strive grain
Contradiction still protrude.Therefore, largely develop the grain-saving types aquacultures such as cattle and sheep, there is especially important meaning to China, also accord with
Close the developing direction of China's animal foodstuff consumption demand.Biological feedstuff of stalk crude fiber content is high, especially suitable for grass such as cattle and sheep
Zoophagous digestive physiology.Therefore develop biological feedstuff of stalk processing, open up feed resource for cattle and sheep cultivation, herbvore family will be pushed
The development that dirty swine produces, drives the optimization of structure of animal husbandry.In addition, as the improvement of people's living standards, nothing to high-quality ecology
Public hazards rice demand is increasing, and ratooning rice regeneration season rice not spray insecticide, rice it is of fine quality famous, just agree with people
Demand, comply with agricultural production supply side reform.Therefore, how to plan as a whole the feeding that China especially southern area is developed animal husbandry
The needs of problems of material shortage and fine quality rice has very important significance for implementing rural area vibration new strategy.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of ratoon rice culture method, to promote the economy of Rice Cropping
Benefit combines the problem of grain raises balance.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of ratoon rice culture method, includes the following steps:
S1, selection head season biomass is big, power of regeneration is strong and the higher rice varieties of protein content, plantation；
S2, head season rice full heading time or full heading time after 10~25 days in cradled, cradle stubble height be 10-
30cm carries out fodder working process to the straw for cradling acquisition；
S3, it cradles in 2 days latter, urea 5-15kg and potassium chloride 5-10kg are applied in rice field per acre；
When S4, season rice grain to be regenerated fall yellow rate up to 95% or more, harvesting.
Further, in step S1, the biomass is 28~30t/hm2, crude protein content 12-18wt%.
In step S1, the rice varieties include Y two excellent 900, river in Zhejiang Province it is excellent 4149, it is grand two excellent 1988, Hunan two excellent 900, hope two
Excellent China one of accounts for.
In step S1, implantation methods are one of transplanting, live streaming, rice transplanting.
In step S2, in head season rice full heading time, urea 10-20kg is applied in rice field per acre, is used as budding fertilizer.
In step S2, cradled in 15-25 days after head season rice full heading time.
In step S2, cradling stubble height is 18-22cm.
In step S2, fodder working process is one of direct ensiling, the broken granulation of wet-milling, dry grinding granulation.It is preferred that
For ensiling.
In step S3, urea 8-12kg and potassium chloride 6-8kg are applied in rice field per acre, are used as hair seed manure.
In the present invention, from kind angle, the selection super hybridized rice that biomass is big, reproducibility is good can be given full play to
Hybrid vigour between crop, while by the science selection of cut issue (practical in full heading time or dough stage), albumen can be obtained and contained
Amount height, the preferable rice straw of palatability, lay a good foundation for its fodder.Secondly as head season rice is cut in advance
It cuts, so that the breeding time in regeneration season extends, and regenerates the day and night temperature in Ji Qisui to maturity period larger (this time is generally right
Answer annual mid or late September to mid or late October), be conducive to improve yield and improve rice matter, compensates for Hybrid Rice matter difference
Defect regenerates rice rice matter 1~2 grade higher than the rice in head season in season.Finally, the field management of cooperation science and in due course receipts
It obtains, realizes that grain raises the ratoon rice culture method taken into account.
Advantages of the present invention: 1) being cradled by the whole strain of head season and ensiling, obtains higher stalk and paddy biomass, for solution
Certainly stalk problem and feed problem provide new approaches；2) shift to an earlier date and cradle and reduce stubble height in head season, vacateed 10 in season for regeneration
~30 days breeding times were conducive to regenerate season stable high yield；3) pass through the factors such as rice varieties, Clipping dates, field management
