Description
Technical field
The present invention relates to Rice Cropping technical field, especially a kind of paddy rice nonirrigated farmland cultural method.
Background technology
Paddy rice originates in Tropical Asian, after China widely plants, gradually travels to all over the world.According to different methods,
Paddy rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.Paddy rice seed is paddy, paddy (grain)
Claim rice, scented rice, rice after shelling.Nearly half population in the world, all using rice as food.The eating method of rice is varied,
There are rice, congee, rice cake, rice cake, rice wine etc..Paddy rice can also make wine in addition to edible, refine sugar and make the raw material of industry, rice husk, rice
Stalk, can be used as feed.China paddy rice main producing region is mainly the Northeast, the Yangtze river basin, Pearl River Delta.Belong to direct economy work
Thing.Still the staple food of 1/3rd mankind in the world.
Paddy rice (scientific name：Oryza sativa) be draft Oryza one kind, be also in Oryza as grain it is main most
Long one kind, also known as Asian type cultivated rice, could also say that rice in simple terms.For annual, grass, list
Leaf, property happiness is warm and humid, there are about 1 to 1.8 meters high when ripe, and leaf is elongated, there are about 50 to 100 centimeter lengths, wide about 2 to 2.5 centimetres.Rice
Rice spend very small, when blooming, arch can be presented in main spray, and little Hua, big portion can be all held between end of the branch down 30 to 50 centimetres
Divide self-pollination and bear seeds, referred to as spike of rice.The size of general spike of rice is long at 5 to 12 millimeters, 2 to 3 mm of thickness.
From ancient times to the present, the planting patterns of paddy rice is mainly by Rice Cropping among rice field, i.e. the base containing a large amount of water
Among；Also have researcher by Rice Cropping process using the mode such as soilless culture, land nursery, so expand Rice Cropping can
The soil utilized, has widened the planting site of paddy rice, reduces Rice Cropping cost；But, for rice cropping process in nonirrigated farmland
The technical scheme of progress yet there are no the report of too many document.
The content of the invention
The present invention provides a kind of paddy rice nonirrigated farmland cultural method, solves above-mentioned technical problem present in prior art.
It is achieved particular by following technical scheme：
A kind of paddy rice nonirrigated farmland cultural method, comprises the following steps：
(1) choose the content of organic matter and be 40-70% soil, then farm manure, the amount of being sprinkled into of farm manure are spread to soil surface
For every mu of 200-300kg, then to its surface quick lime is spread, the consumption of quick lime is 0.3-0.5 times of farm manure, then to its surface
Spray concentration is 1-20% sulfuric acid, then carries out arable land processing using ploughing machine, and tilling depth is 40-50cm, back and forth at arable land
Reason 3-5 times, then whole railway carriage or compartment processing is carried out to soil, a width of 15-20cm in railway carriage or compartment, a length of 2-3m in railway carriage or compartment form ditch, ditch depth is between railway carriage or compartment and railway carriage or compartment
10-15cm, and spread chicken manure after ditch is put in order, then to table surface, 5-10kg is spread according to every railway carriage or compartment, then adjusts the pH value in railway carriage or compartment,
So that pH value maintains 4.2-4.7, and in the water in the surface sprinkling 10-30kg/ railway carriage or compartments of chicken manure, then using the processing of covering with ground sheeting railway carriage or compartment
It is 30-50 days, stand-by；
(2) irrigation water in the ditch between railway carriage or compartment and railway carriage or compartment, the depth of water is 5-8cm, and pours into water methane liquid, and is controlled
Water in ditch processed will not dry up, while also the pH value of adjustment ditch reclaimed water is 4.2-4.7, then apply into ditch N-P-K mixed fertilizer,
It is stand-by；
(3) after step 2) N-P-K mixed fertilizer is applied after 10-15 days, then using seed-grain program request on railway carriage or compartment surface, density of spot seeding
For every railway carriage or compartment 60-100 ridges, the seed-grain granule number per ridge program request is 2-3, then is covered in railway carriage or compartment surface 0.5-1cm using fine earth, and is controlled
Temperature in railway carriage or compartment processed is 28-32 DEG C, after treating that seed-grain sends sprout and is unearthed, and is according still further to 1-2 DEG C/day cooling processing to temperature
After 15-22 DEG C, constant temperature management, you can complete the dry-land cultivation of paddy rice.
Described chicken manure water content is 3-9%.
Described chicken manure be by with pseudo-ginseng, Moschus, marine alga, stalk, sterilization ling according to weight ratio be 100：1:3:2:
50:After 0.5 is mixed, it is placed in pulverizer and is ground into 120-140 mesh powders.
Described chicken manure, after the completion of crushing, then is placed in the environment that temperature is 50-70 DEG C, and adjustment of sprinkling water
After being 11-13% to its water content, then to the concentrated sulfuric acid that its surface spray concentration is 80-88%, the consumption of the concentrated sulfuric acid is sterilizing
1-2 times of clever consumption, after storing up processing 10-20 days, is obtained.
Described farm manure, its water content is 40-60%.
Described farm manure is cow dung, pig manure, chicken manure, duck excrement according to any mixture than mixing.
Described methane liquid is that farm manure is placed in the liquid in methane-generating pit after fermentation process 1-3 months.
Described N-P-K mixed fertilizer is that ammonium-potassium phosphate, potassium dihydrogen phosphate, ammonium sulfate, potassium nitrate are 1 according to mass ratio:1:
0.3:1 mixture mixed.
Described seed-grain is the seed after seed soaking.
Described seed soaking is after seed-grain is selected, to obtain full paddy, and paddy is placed in into temperature for 28-30
DEG C warm water in constant temperature immersion treatment 1-2 days.
Compared with prior art, technique effect of the invention is embodied in：
Nonirrigated farmland is chosen at by the base to rice cropping, and the construction and processing in base are carried out to nonirrigated farmland, and then is caused
Obtain the plantation and cultivation of the suitable paddy rice in base, and by nonirrigated farmland rice cultivation, and by the railway carriage or compartment and railway carriage or compartment set up on nonirrigated farmland it
Between the ditch irrigation water that is formed, and then by being incorporated nutrient solution in water so that the growth of paddy rice obtains normal nutrition supply, and
So that paddy rice will not be in paddy field, and then the labor intensity handled paddy rice is reduced, also, the processing method is simple and easy to apply,
Cost is relatively low, with wide applicability.
The present invention causes the plantation of paddy rice is realized to be planted in nonirrigated farmland by the way that the planting base of paddy rice is handled,
And then the plantation of paddy rice is reduced the waste of seed-grain, reduced the cost of Rice Cropping using point broadcast mode；
And after the completion of program request, germination treatment will be incubated in paddy rice, and then make it that the bud ratio of paddy rice is higher, is survived
Rate is higher, improves the yield of paddy, with significant economic benefit.
