Description
Technical field
The invention belongs to double season super hybridization rice technical fields more particularly to double season super hybridization rice Law of Nitrogen Absorption measuring methods,
Double season Super Rice Planting methods.
Background technique
Currently, the prior art commonly used in the trade is such that
Double cropping of rice has long plantation history in China, and " the two ripe rice " and " ripe rice again " often mentioned in ancient books includes again
Raw rice mixes up rice, makees rice and Cropping Rice etc., reflects that Chinese rice makees the diversity of system, and the appearance of double cropping of rice is to making full use of
Natural resources and human resources, increase grain yield play the role of highly important；Super hybridization rice is improved and is utilized by form
The technology path that inter-subspecific heterosis combines improves yield, will not change the original structure of rice, will not cause rice
Lesion.Nitrogen is the basic component of protein, genetic stocks and chlorophyll and other crucial organic molecules, Suo Yousheng
Object requires nitrogen to support the family.The prior art cannot accomplish that efficiently, fast and accurately obtaining double season super hybridization rice nitrogens inhales
Receive rule；The absorbing rule of nitrogen is not applied in the fertilising of double season super hybridization rices by the prior art, is unable to the rational application of fertilizer, fertilizer
Effect cannot be sufficiently utilized, the waste of fertilizer, increase economic input, and excessive fertilizer is stacked into soil, cause soil hardening,
And the edible quality of rice is poor.
In conclusion problem of the existing technology is:
(1) prior art cannot accomplish efficiently, fast and accurately to obtain double season super hybridization rice Law of Nitrogen Absorption；
(2) absorbing rule of nitrogen is not applied in the fertilising of double season super hybridization rices by the prior art, it is difficult to accomplish to apply
Fertilizer is synchronous in time with fertilizer absorption by rice, quantitatively coincide, and fertilizer cannot be sufficiently utilized, and causes the waste of fertilizer, increases
Economic input, excessive fertilizer are stacked into soil, not only cause soil hardening, but also influence the edible quality of rice.

Rice five Feng You T025 (breeding unit: agricultural college of Agricultural University Of Jiangxi；Cultivar origin: five rich A × prosperous extensive T025；09 month 2010
Country's authorization, number: state examines rice 2010024；The Ministry of Agriculture regards as super rice varieties within 2010)；Before nursery to seed at
Reason；
Step 2: respectively in the seedling stage of double season super hybridization rices, jointing stage, boot stage, blooming stage, milking maturity initial stage and milking maturity latter stage
It is sampled；
Step 3: choosing 30 plants of representative plant every time, divides sample by organ, then in 70 DEG C~80 DEG C of air blast
Finish 1h~1.5h in drying box, and drying to constant weight at 80 DEG C~90 DEG C；
Step 4: it is cooling in drier, dry biomass is measured after cooling, is surveyed after pulverizing using Nesslerization
Fixed each organ total nitrogen content.
Further, in step 1, fixed experiment field is chosen, keeps soil, moisture, living environment consistent, reduces sample
Product error.
Further, it in step 2, is sampled as before fine day is afternoon, night dew comes, less moisture content.
Further, in step 3,30 plants of representative plant is chosen, 10 plants are one group, divide sample by organ, every group is done
3 parallel tests, results are averaged；
Further, cooling in drier in step 4, it avoids absorbing moisture in air, keeps the quality of dry matter.
Another object of the present invention is to provide double season Super Rice Planting methods, specifically includes the following steps:
Step 1: choosing super rice of double seasons, and early rice chooses super hybridization rice land two excellent 819, and it is rich that late rice chooses super hybridization rice five
Excellent T025；Seed is handled before nursery；
Step 2: treated seed puts into Germinator and carries out vernalization, through greenhouse sprout-tray seedling growth, wholeheartedly two leaves into
Row machine rice transplanting；
Step 3: growth period controls rice field water, absorbing rule top dressing 2-3 times according to nitrogen of growth period, attention control
Rice blast and insect pest；
Step 4: it after early rice harvesting, is ploughed, soaked field, the early rice straw for removing the floating water surface, applies base fertilizer, carry out
Five Feng You T025 kind of super hybridization rice is planted.
Further, in step 1, seed is handled before nursery, is sterilized, sterilization.
Further, fertilizer is organic farmyard manure.
In conclusion advantages of the present invention and good effect are as follows:
Measuring method can efficiently, fast and accurately obtain double season super hybridization rice Law of Nitrogen Absorption through the invention；Using
Double season Super Rice Planting methods, according to the absorbing rule rational application of fertilizer of nitrogen, fertilizer efficiency is sufficiently utilized, and reduces the waste of fertilizer,
Economic input is reduced, the economic benefit of kind of grain is improved, improves super yield of double seasons；The use of organic farmyard manure effectively improves
Paddy soil, and improve the edible quality of rice.
