Description

Method of raising seedling is planted between a kind of rice
Technical field
The present invention relates to raising rice seedlings field, in particular to method of raising seedling is planted between a kind of rice.
Background technique
Rice is annual gramineae plant, and about 1.2 meters high, leaf is long and flat, and panicle is made of many small ears.Institute Knot is paddy in fact, and rice or rice are claimed after decladding.Rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous Rice.Claim rice or rice after the tied grain of rice decladding of rice.Rice can also make wine in addition to edible, refine sugar and make the raw material of industry, rice Shell, rice straw also have many use.Rice belongs to grass family Oryza, is an extremely ancient crop.
The planting technology of rice, including rice field and rice transplanting, are in Chinese invention.It is that Shen Nongshi instructs people such as in legend Which kind of rice.The cultivation of rice removes traditional artificial cultivation mode at present, also there is the cultivation mode of high mechanization.But still it does not lose following Step: site preparation, rice transplanting, weeding deinsectization, fertilising, fills draining and harvest at nursery.
Summary of the invention
For mirror with this, it is an object of the invention to propose to plant method of raising seedling between a kind of rice.
The technical scheme of the present invention is realized as follows:
Method of raising seedling is planted between a kind of rice, comprising the following steps:
Step 1: straw powder and wheat bran being mixed according to weight ratio 1:1-3, add water to soak, and compost fermentation agent mixing is added Uniformly, the dosage of compost fermentation agent is the 3-7%wt of straw powder and wheat bran total weight, prepares strain mixture；
Step 2: brown alga, sawdust, guanite, wind desiceted soil, nutritional additive and water being uniformly mixed, are added obtained by step 1 Strain mixture is uniformly mixed, compost fermentation, and cooling and heat dissipation after fermentation maturity prepares Nutrition Soil；
Step 3: choose it is full, particle is larger, shape it is regular by rice paddy seed, be exposed to the sun after 2-3 days in the sun, use Aqueous sodium hypochlorite solution impregnates, and is washed with clear water to neutrality after immersion, is then impregnated with gibberellin, takes out and dries after immersion；
Step 4: choose full, shape it is regular by Chinese Milk Vetch Seeds, be exposed to the sun after 1-2 days in the sun, with addition fine sand, Rubs mutually wipes Chinese Milk Vetch Seeds surface wax, the aqueous solution soaking of potassium dihydrogen phosphate and gibberellin is then used, after immersion Taking-up is dried；
Step 5: adding water to soak step 2 gained Nutrition Soil, be laid in seedling-cultivation plate, Nutrition Soil is with a thickness of 1-3cm, top Step 3 gained rice paddy seed is sowed, every planting Chinese Milk Vetch Seeds 1-3cm between 10-15cm, is then covered above two kinds of seeds The Nutrition Soil of 1cm thickness completes sowing；
Step 6: step 5 gained seedling-cultivation plate being put into raising chamber, seedling management is carried out；
Step 7: when seedling growth is to 10-18cm high, being transferred in paddy field and cultivate.
Further, in the step 2, nutritional additive include feldspar in powder, ground phosphate rock, celestite powder, chlorination zinc powder, Lepidolite powder, medical stone powder, chelated magnesium, Chelated Manganese, chelating selenium and chelated iron, calculate, amount ratio 50-80:30- by weight 50:5-10:5-10:5-10:5-10:2-5:2-5:2-5:2-5；Calculate by weight, brown alga, sawdust, guanite, wind desiceted soil, The amount ratio of nutritional additive and water are as follows: 100-300:100-200:100-150:800-1000:50-300:500-2000.
Further, in the step 2, the compost fermentation time is 7-15 days, and compost temperature is 50-70 DEG C.
Further, in the step 2, the dosage of strain mixture is the 1-3%wt of Nutrition Soil total weight.
Further, in the step 3, the concentration of liquor natrii hypochloritis is 1-3%wt, soaking time 1-3min, leaching Steeping temperature is 20-22 DEG C；The concentration of Gibberellins solution is 30-40ppm, soaking time 20-30h, soaking temperature 20-25 ℃。
Further, in the step 5, the thickness of sowing of rice paddy seed is ten thousand/m of 2-102；The sowing of Chinese Milk Vetch Seeds Density is 2000-4000/m2。
Further, in the step 6, when seedling manages, the humidity of raising chamber is in 50-70%, soil moisture 20- 30%, light application time is 12-16h/ days, and light application time temperature is 15-25 DEG C, and interlunation temperature is 10-15 DEG C.
Compared with prior art, the invention has the benefit that
1) method of raising seedling bud ratio of the present invention is high, and seedling growth is fast, and rice shoot length is neat；
2) present invention cultivates obtained rice shoot rich in various trace elements, after being transferred to common crop field, in the rice of harvest Also the microelements such as selenium rich in, zinc；
3) present invention will plant between rice and Chinese milk vetch, after being transferred to crop field, can enhance paddy field nitrogen fixation effect, make harvest Rice pellets are fuller.
