Embodiment
For making object of the present invention, technical scheme and advantage clearer, referring to accompanying drawing and enumerate preferred embodiment, the present invention is described in more detail.But, it should be noted that, many details of listing in specification are only used to make reader to have a thorough understanding to one or more aspects of the present invention, even if do not have these specific details also can realize these aspects of the present invention.
The present inventor considers, it is a kind of technology of irrigating, utilizing natural precipitation to be engaged in agricultural production completely of not needing that rain is supported, if can support condition based on rain, in Typical Steppe, plant alfalfa, will greatly reduce costs.Thus, the weather conditions of the present inventor to Typical Steppe, and the characteristic of alfalfa is studied, find Typical Steppe (as Inner Mongolia Steppe district) arid in spring windy (be unfavorable for pale reddish brown lucerne germinates keep a full stand of seedings), winter severe cold (being unfavorable for that alfalfa seedling passes the winter), summer temp is higher and rainwater is more.
In conjunction with the research of the weather conditions to Typical Steppe, and the optimal temperature of the sprouting of the seed of alfalfa (25 ℃～30 ℃), in technical scheme of the present invention, at the early summer (early and middle ten days in June) of Typical Steppe, sow the seed of alfalfa, make alfalfa can rely on the temperature in summer and rainwater to germinate, grow; And, plantation not the cradling then of alfalfa, to guarantee that alfalfa passes the winter smoothly, and within continued growth 1-2 month after Second Year alfalfa is turned green, have that better nutritivity is worth, cradle during economic worth; Thereby realize in arid, semiarid Typical Steppe and plant alfalfa in the foster low cost mode of rain.
The present inventor finds, in alfalfa, No. 3 assorted russian fenugreek herbs in No. 2, grassland clover or grassland or Ao Han clover are more suitable in arid, the plantation of semiarid Typical Steppe, therefore, choose the seed of No. 3 assorted russian fenugreek herbs in No. 2, grassland clover or grassland or Ao Han clover as the seed of alfalfa to be sowed.
The rainy season of considering Typical Steppe is shorter, and the hard seed rate of the seed of alfalfa is generally 5%～30%, for the seed that prevents alfalfa can not be sprouted in time or not sprout in the rainy season of Typical Steppe, the present invention is before the seed of sowing alfalfa, the seed of also treating the alfalfa of sowing carries out broken skin processing (abolishing strong processing): for example, with the mill seed of alfalfa of rice mill, or before sowing, shine 3～5 days breaking dormancy; Adopt ten thousand/ammonium molybdate or 3/10000ths BASs to soak the seed of alfalfa; Or, the seed of alfalfa is carried out to Short-Term High Temperature (50～60 ℃, 0.25～1h) and processes.Like this, the seed for the treatment of the alfalfa of sowing carries out broken skin processing, can shorten the sprout time of hardseed, is conducive to the emerging of seed of alfalfa, and then can guarantee after alfalfa is emerged, based on Typical Steppe temperature and the rainwater Fast Growth in summer.And the seed that can also treat the alfalfa of sowing carries out legume inoculation, to increase soil nitrogen, increase soil fertility, thereby guarantee regularity and the Miao Zhuan of emerging.
The seed wait the alfalfa of sowing of choosing is being carried out after broken skin processing, using the seed of these broken skins alfalfa after treatment to plant alfalfa in Typical Steppe.Particularly, the flow process of the method for the Typical Steppe plantation alfalfa that the embodiment of the present invention provides, as shown in Figure 1, specifically comprises the steps:
S101: carry out whole ground, apply base manure being positioned at the plot (plot of choosing in Typical Steppe) of Typical Steppe.
Particularly, alfalfa is not strict to the requirement of soil condition, while choosing plot (selection of land) in Typical Steppe, can specially not consider soil basis, preferably, can choose neutrality or alkalescence soil.
After the selection of land of Typical Steppe, whole ground is carried out in the plot of choosing, be specially: rake, suppression are ploughed, dredged in the plot of choosing successively.Wherein, ploughing depth is 25～30cm.Because the seed of alfalfa is tiny, the thin and delicate growth of seedling is slow and to push up native power poor, and therefore in the time of wholely, the thin rake of can deep ploughing, makes Panasonic's reality on soil, is beneficial to emerge; And ploughing, dredging after rake, the plot of choosing is suppressed, in order to soil moisture conservation.
And, the plot of choosing in Typical Steppe is carried out in the process on whole ground, in conjunction with whole, use sufficient base manure, base manure can be specifically farmyard manure, the amount of application of farmyard manure is 60～75t/hm
2; Or base manure can also be diammonium phosphate, the amount of application of diammonium phosphate is 75～150kg/hm
2.Base manure can also be common phosphate fertilizer, and amount of application is 750kg/hm
2.Further, the concrete amount of application of base manure can also be determined on the basis of the soil nutrient composition measurement in the plot of choosing.
S102: early June or the middle ten days then, sow in the plot of choosing.
Conventionally, the seeding method of alfalfa broadcasts sowing, drilling, broadcasts etc.Wherein, drilling is every setpoint distance, by the sowing of embarking on journey of the seed of alfalfa, and with the seeding method of broadcasting with earthing.Because drilling seeding method is convenient to daily management, therefore the present invention adopts the seed of drilling seeding method sowing alfalfa.In actual production process, the line-spacing of drilling can be 20～60cm; For example, under dry farming, grass seed production field can adopt the wide line-spacing drilling of 45～60cm.And the fertile sowing of band is a kind of comparatively advanced practical type of seeding, i.e. fertilising is carried out with sowing simultaneously, during sowing, fertilizer is directly executed below seed, can make like this seedling of alfalfa absorb in time nutrient.
Particularly, in this step, early June or the middle ten days then, in the plot of choosing, sow; Wherein, a kind of method of sowing in the plot of choosing is, the seed of the seed of alfalfa to be sowed and gramineous forage grass (as lyme grass) is carried out to mixed seeding, is specifically as follows:
By after the seed of the alfalfa of sowing and the seed of gramineous forage grass mix, in the plot of choosing, adopt drilling seeding method, the mixed seed of sowing of embarking on journey; Namely, in the same a line in the plot of choosing, comprise the seed of alfalfa to be sowed and the seed of gramineous forage grass.Or, adopt drilling seeding method, row between the seed of the seed of alfalfa to be sowed and gramineous forage grass is sowed in the plot of choosing; Like this, in the same a line in the plot of choosing, only comprise the seed of alfalfa to be sowed or the seed of gramineous forage grass.Wherein, when the seed of the alfalfa of sowing and the seed of gramineous forage grass carry out mixed seeding, the seeding quantity of alfalfa is 7.88～15kg/hm
2, the seeding quantity of gramineous forage grass is 21.43～24kg/hm
2.And, during mixed seeding, also adopt and be with fertile seeding method, fertilizer is executed to 4～6cm place below the seed of sowing.
The another kind of method of sowing in the plot of choosing is the seed of alfalfa to be sowed is carried out to clean culture (only sowing the seed of alfalfa in the plot of choosing), and clean culture seeding quantity to be 11.25～18.75kg/hm
2.Particularly, by when the seed of the alfalfa of sowing carries out clean culture, can adopt drilling, be with fertile seeding method, by the planting seed of alfalfa to be sowed in the plot of choosing; When wherein, band fertilizer is sowed, fertilizer is executed to 4～6cm place below the seed of sowing.
And in this step, the sowing depth of mixed seeding or clean culture is 1～3cm.More preferably, the sowing depth of mixed seeding or clean culture can be determined according to the soil types in the plot of choosing: when the soil in the plot of choosing is non-sand soil, sowing depth is 1～2cm; When the soil in the plot of choosing is sand soil, sowing depth is 2～3cm.In addition, sowing depth can also be determined in conjunction with soil moisture, sowing time and soil density.
S103: plot is after planting suppressed.
Particularly, owing to the present invention is based on the rain condition of supporting, in Typical Steppe, plant alfalfa, and non-irrigated condition, and the seed of alfalfa is tiny, therefore, need to suppress plot after planting, be beneficial to soil moisture conservation, and be beneficial to the seed close contact of soil and alfalfa, promote the seed germination of alfalfa.
S104: field management is carried out in plot after planting.
Particularly, field management is carried out in plot after planting and specifically comprise: before alfalfa is emerged, the plot chosen meets after rain, and rake is dredged in the plot of choosing.All can harden after meeting rain conventionally in the plot of choosing due to Typical Steppe, therefore, rake is dredged in the plot of choosing and can remove in time soil compaction layer, and preventing from meeting rain soil compaction affects alfalfa and emerge.
Further, field management is carried out in plot after planting can also be comprised: after planting, remove the weeds in plot after planting, prevent that alfalfa is subject to weeds impact and poor growth in seedling stage; Prevent and treat the damage by disease and insect of alfalfa, to guarantee the grass yield of alfalfa; And after alfalfa is emerged, avoid livestock to trample on and gnaw, guarantee the normal growth of alfalfa.
S105: the alfalfa of planting in to the plot of choosing in Second Year late July cradles, and cradles stubble height and is more than or equal to 5cm.
Particularly, Typical Steppe winter severe cold, passes the winter smoothly and is beneficial to turning green of Second Year for the alfalfa of guaranteeing plantation, and the present invention does not cradle alfalfa then Alfalfa Growing.Like this, after Second Year alfalfa is turned green, also can further rely on temperature and the rainwater in Typical Steppe summer to grow.
The situation of carrying out mixed seeding for alfalfa and gramineous forage grass, cradled the alfalfa after turning green and gramineous forage grass in Second Year late July; For alfalfa, carry out the situation of clean culture, in Second Year late July, the alfalfa after turning green is cradled.And, for guaranteeing passing the winter smoothly of Second Year, cradle stubble height and be more than or equal to 5cm.
And to crude protein, raw fiber, the ash of supporting the condition growth alfalfa of 2 years based on rain in the Typical Steppe nutrient component of grading, and stem/leaf ratio is measured before the present inventor.Fig. 2 shows the stem/leaf ratio of the alfalfa of different times mensuration, and in the time of can finding out July, the cauline leaf of alfalfa is smaller; Table 2 and Fig. 3, Fig. 4 show the content of the nutrient component in stem and the leaf of the pale reddish brown lucerne of different times, can find out that the content of crude protein in July stem and leaf is higher, and raw fiber and ash content are the trend of increase.Thus, the present invention is determined at Second Year late July the alfalfa after turning green is cradled, and now, alfalfa Grass Quality is better.Meanwhile, for guaranteeing that the alfalfa after Second Year cradles can pass the winter smoothly, cradle stubble height and be more than or equal to 5cm, be not less than 5cm.
Table 2
Afterwards, the alfalfa that can plant in to the plot of choosing in Typical Steppe in annual late July cradles, and cradling stubble height is to be also more than or equal to 5cm(to be not less than 5cm).After cradling, reduce as far as possible and cradle the alfalfa herbage that the obtains airing time in the ground, after cradling the alfalfa herbage bundling obtaining, deliver in time Huo Chu straw shed, threshing ground, it is dried naturally at ventilation bield, guarantee Grass Quality and output, to obtain good economic benefit.
And, annual, carry out in the process of field management in to the plot of choosing afterwards, can also be when the alfalfa of plantation form shoot and topdress during the growth animated period of alfalfa, the selected fertilizer that topdresses is generally quick-acting chemical fertilizer.For leguminous forages such as alfalfas, except Seedling Stage needs a small amount of nitrogenous fertilizer, mainly impose phosphorus, potash fertilizer.
In sum, in technical scheme of the present invention, in conjunction with the weather conditions of Typical Steppe and the characteristic of alfalfa, choose the seed of suitable No. 2, the grassland clover growing in Typical Steppe or the assorted russian fenugreek herb in No. 3, grassland or Ao Han clover as the seed of alfalfa to be sowed; The plot of choosing carried out to whole ground, applying after base manure, early June or the middle ten days then, the seed of the seed of alfalfa after treatment to be sowed broken skin and gramineous forage grass is carried out to mixed seeding, or, the seed of alfalfa after treatment to be sowed broken skin is carried out to clean culture; Afterwards, plot is after planting suppressed; Meet after rain in plot before alfalfa is emerged, after planting, and rake is dredged in plot after planting; In Second Year late July, the alfalfa of plantation is cradled, cradle stubble height and be more than or equal to 5cm.Thereby, based on the rain condition of supporting, realize in Typical Steppe plantation alfalfa, greatly reduce the cost of plantation alfalfa.
Further, owing to making to plant the cost of alfalfa in Typical Steppe plantation alfalfa based on the foster condition of rain, therefore method of the present invention is more suitable in Typical Steppe spread plantation alfalfa, in the ecological construction that is beneficial to Typical Steppe, also can obtain higher economic benefit.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
