Description
Technical field
The invention belongs to Rice Cropping technical field, and in particular to a kind of method of raising early season late-rice rice yield.
Background technology
Paddy rice, is annual gramineae plant, high about 1.2 meters, leaf length and it is flat, panicle is made up of many small ears.Water
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, which is tied, claims rice or rice after the grain of rice shells.
Paddy rice can also make wine in addition to edible, refine sugar and make the raw material of industry, rice husk, rice straw also have many use.Paddy rice belongs to grass family
Oryza, is an extremely ancient crop.According to archaeological discovery, plantation history at least 7000 year or so of the paddy rice in China.Generation
Cultivated rice in boundary has 2 kinds i.e. Asian Cultivated Rice and Oryza glaberrima Steud.Wherein Asian Cultivated Rice cultivated area is big, spreads all over the world
Each rice region, so referred to as common cultivated rice.A host of facts prove, south China be at least common cultivated rice the centre of origin it
One.Paddy rice is just broken up through long-term evolution and moulding again for different ecological condition, and Chinese scholar fourth grain husk (1957) is according to right
The origin of Cultivated Rice in China (category Asian Cultivated Rice), develop and about the research identification of ancient books, Cultivated Rice in China is divided into Xian, round-grained rice
Two subspecies, and according to the soft light reaction of kind, water requirement and endosperm starch characteristic etc. are divided into early, evening again under Xian, Via-back puncture,
Water, land, glue the different type such as (non-glutinous), glutinous.So strictly speaking, Xian, round-grained rice and glutinous rice and be listed in classification be it is inapt,
Actually Xian, Via-back puncture have viscous and glutinous point, and the COMPARISON OF CHARACTERS of long-grained nonglutinous rice is close to its ancestors' wild rice, so there is scholar to think
The non-basic model of long-grained nonglutinous rice, the non-anomaly of japonica rice, long-grained nonglutinous rice is suitable in low latitudes, the plantation of low altitude area damp-heat area.By kind for many years
Empirical discovery is planted, the paddy rice of different cultivars differs for date of seeding, illumination utilization, the influence of rich water quality management, and existing kind
Planting technology is not distinguished by for the Rice Cropping mode of different rice varieties, and the yield of paddy rice has not given play to huge
Room for promotion.
The content of the invention
The purpose of the present invention is that there is provided a kind of method for improving early season late-rice rice yield, reality the problem of being directed to existing
High yield is showed.
The present invention is achieved by the following technical solutions：
A kind of method for improving early season late-rice rice yield, comprises the following steps：
（1）At annual 20-25 in March days, full early season late-rice rice paddy seed is selected, is soaked 5-8 hours using seed-soaking liquid, sowing
In rice seedling bed, while spraying lime water, every mu of consumption is 20-25 kilograms, and the thinner ratio of lime water is：Quick lime is than water
1：Each main nutrient composition content is in 480-500, rice seedling bed soil：Agron 55-60 g kgs, organic nitrogen 2.5-2.8
G kg, inorganic nitrogen 0.3-0.4 g kgs, available potassium 230-250 milli/kilogram, rapid available phosphorus 10-15 mg/kgs；
（2）In 1-10 days May then, by shoot transplanting equipment to rice field, 2-3 days before transplanting, rice shoot is extracted, spray concentration is 90-
110ppm horseradish powder preparation, and soaked rice shoot 10-12 hours using paddy field water, distance between rows and hills is transplanted according to 30 × 15 centimetres,
After transplanting 5-8 days, per hectare applies 220-250 kilograms of nitrogenous fertilizer, after transplanting 13-15 days, and per hectare applies 70-90 kilograms of phosphate fertilizer,
After transplanting 15-20 days, per hectare applies 60-70 kilograms of potash fertilizer；
（3）Enter the spike of rice phase in paddy rice, disease control is carried out according to the upgrowth situation of paddy rice, it is main to eliminate disease using physical method
Insect pest, supplemented by Agro-chemicals control, and by dosing mitigate be normal 70-80%, while using 2-3 monthly age greatly
Duck carries out biological control, puts in a suitable place to breed after the rain, and every mu is put in a suitable place to breed 60-80 only, according to the in good time supplement irrigation water of amount of rainfall, it is ensured that young fringe
The formation phase to all bloom scion complete during water level in paddy field be maintained at rice seedlings 60-70% height.
It is used as further improvement of these options, step（1）6-8 is dried under sunshine before middle rice paddy seed seed soaking small
When, the clear water for reusing flowing soaks 2-4 hours, and described seed-soaking liquid is 6000-8000 times of dilution of Prochloraz, and soak will
Beyond 0.5-1 centimetres of seed, rinsed 3-5 times using clear water after immersion.
It is used as further improvement of these options, step（2）Described in the preparation method of horseradish powder preparation be：By mountain
Certain herbaceous plants with big flowers root is pulverized after drying, and is added in garlic infusion liquid and is soaked 2-3 hours, stirs.
As further improvement of these options, the pH value of seedling soil is 6.4-6.6, the P in soil H values of paddy field cultivation
For 6.5-6.7.
The present invention has advantages below compared with prior art：The growth that the present invention have studied early season late-rice rice varieties is special
Point, for date of seeding, the effect of fertilizer efficiency, breeding time and light temperature utilization relation for the influence of yield, comprise the following steps：（1）
According to adaptability of the early season late-rice paddy rice for temperature, selection carried out sowing seedling at annual 20-25 in March days, from the choosing of seed
Select, the processing of seed to the nutrient situation in rice seedling bed, the experiment that have passed through repeatedly obtained optimal output results；（2）Working as
In the 1-10 days May in year, by shoot transplanting equipment to rice field, the breeding time of time period paddy rice and temperature and the conformability of illumination are maximum,
Breeding time accumulated temperature and illumination hour are improved 110-120 DEG C and 88-93 hours；（3）Enter the spike of rice phase in paddy rice, pest and disease damage it is anti-
Control particularly critical, the method that the present invention is combined using physics, chemistry, biofacies, based on physical control, reduction chemical agent
Use, improve the security of paddy rice.The 18-20% by output increased, and particle is uniformly full.
