Description

A kind of Shandong District spring rice nonirrigated farmland method for culturing seedlings
Technical field
The present invention relates to arviculture planting technology field, more particularly to a kind of Shandong District spring rice nonirrigated farmland is educated Seedling technical method.
Background technology
Rice is that cultivated area and total output are only second to one of staple food crop of wheat in the world, global half with On population all using rice as staple food, while be also the important cereal crops in China, total cultivated area and total output occupy the world Forefront.
Rice is pyrophilous, how wet, short-day.Rice is divided into Seedling Stage, tillering stage, puberty, productive phase in life. The upgrowth situation of the Seedling Stage of rice determines the development condition in the later stage of rice or even last yield.The Seedling Stage of rice Growth can be divided into the sprouting of seed rice and the growth of rice shoot.
The growth of rice is since being sprouted seed.When seed rice water swelling, when radicle breaks through kind shell exposing white point, Show money or valuables one carries unintentionally;When radicle, which is stretched out, to be stretched out up to seed length half up to seed length or plumule, just it is known as germinateing.Seed is sprouted It needs to absorb enough moisture, while temperature is more suitable for 20-25 DEG C, germinate at this temperature neat and healthy and strong.And it protects Card seed rice, which can carry out oxygen, which carries out breathing, to germinate.
After germination, rice enters seedling growth stage, and the period is to environmental condition requirement:
1. temperature:Japonica rice 12 DEG C of minimum temperature of emergence, long-grained nonglutinous rice 14 DEG C of minimum temperature of emergence.Under this temperature condition, emergence Rate is low, and speed is slow.20 DEG C or so of mean daily temperature after emergence is most advantageous for cultivating strong seedling.It is excessively high it is too low not Profit.It is necessary to cold-proof when reaching 5-7 DEG C such as low temperature, otherwise rice bacterium is by freeze injury.
2. oxygen:Rice shoot is in waterflooding retarded growth, and root is few, seedling is weak.Especially before tri-leaf period, flood The unfavorable nurturing staff of water, therefore, in the seedling raising process of rice seedling bed, small water frequent irrigation, not water conservation layer, advantageous nurturing staff.Moistening nursery, Arid nursery is provided to nurturing staff, meets requirement of the seedling growth to oxygen.
3. moisture:Increase with seedling growth.Only the 40%% of maxmun field capacity need to be kept before emergence, so that it may be met Germination, emergence need.Also water layer is not required to before tri-leaf period, soil moisture content is 70% or so.Soil moisture is not after three periods It is low to influence paddy growth less than 80%.
4. illumination:Illumination is one of essential condition of nurturing staff.Because illumination is sufficient, rice shoot could be utilized in air Carbon dioxide and root absorption moisture, nutriment, pass through photosynthesis synthesis of organic substance, carry out growth and development
Shandong District early spring low temperature is short of rain.During the 4-5 months, Shandong District day temperature is generally between 10-20 DEG C, Nocturnal temperature is between 7-8 DEG C.Water can not be normally carried out in paddy field since regional spring water shortage is serious again simultaneously Rice is sowed.Development nonirrigated farmland rice cultivating technique can reduce Rice Production water, save water resource, avoid dry year to water Rice production causes big influence.
Invention content
The technical problems to be solved by the invention are that the present invention proposes a kind of Shandong District spring rice nonirrigated farmland and educates Seedling technical method provides necessary reliable technological means to expand Monitoring of Paddy Rice Plant Area in Shandong arid area.The method of the present invention Improved by improving technology and carry out the rice seedling rate of rice nonirrigated farmland sowing in spring Shandong District, ensure rice in water shortage and It can normally emerge in the environment of low temperature.
In order to solve the above technical problems, the present invention provides a kind of Shandong District spring rice nonirrigated farmland method for culturing seedlings, including Following steps:
A site preparations;
B. ditching;
C. it applies fertilizer;
D. it soaks seed;
E. vernalization;
F. it sows;
G. epiphragma;
H. it manages.
Further comprise:A site preparations:Rotary tillage is carried out to nursery field, while extract field and leave in 15~April 25 April Root stubble, rotary tillage finishes, rakes, and suppresses.
Further comprise:B. ditching:Whole good plot is shoveled out into several seedling ponds, the wide 1.2- in seedling pond with grafter 1.5m, long 8-10m.
Further comprise:B. ditching:Seedling pond is in channel form, and seedling bed bottom is smooth, and bottom should be less than field 5-6cm.
Further comprise:C. it applies fertilizer:To seedling pond basal dressing, every seedling pond applications of farmyard manure, i.e. cow dung, chicken manure mixing 25- 30kg。
Further comprise:D. it soaks seed:Seed to be broadcast is dried into 24~72h in 30 DEG C~40 DEG C baking ovens;After drying Seed be put into normal-temperature water and soak seed, while be put into seed soaking medicine Prochloraz, dosage is adds 2-3g miaows in 30 jin of normal-temperature waters Fresh amine pulvis;Seed soaking time is 2-3 days, a water is during which every other day changed, until seed rice shows money or valuables one carries unintentionally.
Further comprise:E. vernalization:The rice straw that rice leaves is harvested with last year to wrap up the rice paddy seed to show money or valuables one carries unintentionally, It is put into bucket, while is full of bucket top with remaining rice straw, close the lid, the time continues 24-36h.
Further comprise:F. it sows:The rice paddy seed of budding uniformly to be broadcast in the breeding pond dug, sowing finishes, The field fine earth of 1-2cm thickness is uniformly sprinkled into seedling pond, the rice being sown into is covered.
Further comprise:G. epiphragma:Covered with double-deck transparent plastic film, film with to contact place soil pressure tight.
Further comprise:H. it manages:The water period, and the film at the both ends in seedling pond is pulled open at noon is applied every time simultaneously, Expose openning 5~30 minutes.
Advantageous effect of the present invention includes:The method of the present invention can save water resource 80%, ensure rice in water shortage and low It normally emerges, while pest and disease damage is greatly reduced, and then reduce 40%-50% applications of pesticide amount under the environment of temperature.
Specific embodiment
The present invention is described in detail with reference to embodiment.To make the objectives, technical solutions, and advantages of the present invention clearer, bright Really, the present invention is described in more detail by the following examples, but the invention is not limited in these embodiments.
In one embodiment of this invention, following Shandong District spring rice nonirrigated farmland method for culturing seedlings is provided:
