Description

A kind of method improving Head Rice Rate
Technical field
The present invention relates to rice cropping and farming to learn a skill field, specifically a kind of method improving Head Rice Rate.
Background technology
Head Rice Rate is an important measurement index of processing quality (being again milled quality).The head rice rate of Oryza sativa L. is high, illustrates that the processing quality of Oryza sativa L. is good, also illustrates that the Oryza glutinosa grouting of Oryza sativa L. is more abundant, it is possible to roll, through Oryza glutinosa, the head rice rate retaining higher rate after processing.So, the Oryza glutinosa of Board Lot just can produce more head milled rice, it is thus achieved that higher economic benefit.In view of the importance of head rice rate, research worker is just studied in Crop Genetic Breeding, plantation planning, high-yield culturing etc., improves the milled quality of rice, also includes improving its head rice rate.
Summary of the invention
The purpose of the present invention, is to provide a method improving Head Rice Rate, provides reference for improving Rice Production benefit.
A kind of method improving Head Rice Rate of the present invention, comprises the steps:
1., the choosing and division of experimental plot: choose a Rice Production producing region, then the experimental plot of selected shape rule in Rice Production producing region, experimental plot is isolated into some deciles, each etc. be divided into a cellular zone；
2., seed selection: choose meet step 1. adapt to produce the growth of experimental plot, district, full grains, against the strong rice varieties of property；
3., the mensuration of the full Se content of experimental plot soil: measure selected test field Selenium in Soil content, as Oryza sativa L. carries out after test increasing the foundation of selenium intervention intensity；
4., the plantation of rice varieties: in rice varieties planting season, by step 2. in the Rice Cropping chosen in the cellular zone that 1. step is arranged, the Monitoring of Paddy Rice Plant Area of each cellular zone, planting density, fertilizer application condition are all identical, and using at least three cellular zone as a repeating groups；
5., field management: in the paddy growth stage, each repeating groups is manually applied different amounts of selenium, and carry out unified irrigation, disease pest control of weeds processes, and in each unit district of each repeating groups to execute selenium amount identical, gather in after Oryza sativa L. maturation；
6., the mensuration to Head Rice Rate: during Oryza sativa L. maturation, it is sampled averaging to each repeating groups, measure rice yield and the head rice rate of each repeating groups, and the head rice rate of each repeating groups is compared, judge the head rice rate yield combination of each repeating groups in experimental plot, so that it is determined that step 1. experimental plot needs the selenium content used.
Preferably, experimental plot is isolated into some deciles by described 1. middle employing plastic sheeting or fiberglass tile, meanwhile, repeats laid mulch film in the joint of plastic sheeting or fiberglass tile, to prevent fertilizer crossfire in process of the test, thus affecting the accuracy of test；
Preferably, step 5. in, when manually increasing selenium when adopting the method executed of base to carry out, select ore deposit fertilizer to increase selenium, and the selenium amount of each repeating groups apply according to incremental mode；Preferably, when adopting the mode that base is executed manually to increase selenium, selenium amount is according to 0kg/667m2、10kg/667m2、20kg/667m2、30kg/667m2、40kg/667m2、50kg/667m2、60kg/667m2The gradient that enriches carry out；Preferably, when the method adopting root outer spraying carries out manually increasing selenium, select sodium selenite or increase selenium containing selenium product, and the mode being incremented by according to each repeating groups selenium amount applies；Preferably, selenium amount is according to 0g/667m2、0.5g/667m2、1g/667m2、1.5g/667m2、 2g/667m2、2.5g/667m2、3g/667m2The gradient that enriches carry out；
Wherein, base execute according to 0kg/667m2Carry out the repeating groups increasing selenium test as check plot；According to 0g/667m in root outer spraying method2Carry out the repeating groups increasing selenium test as check plot.
Preferably, it is before Rice Heading 5～7 days that described root outer spraying increases the selenium time, and adopts foliage-spray method to spray.
A kind of method improving Head Rice Rate of the present invention, its advantage is: chooses test field and is divided into some deciles, under the premise that Soil Background and management environment are consistent, gradient increases selenium rice cultivation, adopt the method choosing best selenium amount of application, make Oryza sativa L. obtain high yield meanwhile, it is capable to by the raising of head rice rate, increase the yield of unit are Oryza sativa L. polished rice；Meanwhile, the polished rice yield of increase is to carry out under the premise not increasing cultivated area, by enriching selenium fertilizer, improves the output value of Oryza sativa L., too increases rice agriculture and processing enterprise's income thereof.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described:
1., the choosing and division of experimental plot: choose a Rice Production producing region in Jing Zhou, Hubei, then choose the rectangular test field that length-width ratio is not more than 1:4 in Rice Production producing region, adopt plastic sheeting that experimental plot is isolated into 6 deciles, each etc. be divided into a cellular zone；
2., seed selection: choose meet step 1. adapt to produce the growth of experimental plot, district, full grains, strong stress resistance the long agriculture round-grained rice of late round-grained rice kind 1 as test kind；
3., the mensuration of the full Se content of experimental plot soil: adopting the content of Atomic Fluorescence Spectrometry test field Selenium in Soils, this experimental plot detected value is 0.28mg/kg；
4., the plantation of rice varieties: in rice varieties planting season, by step 2. in the Rice Cropping chosen in the cellular zone that 1. step is arranged, and the cultivated area of long agriculture round-grained rice 1 of each cellular zone, planting density are all identical；For the accuracy of guarantee test and to eliminate soil fertility error, every three cellular zones are set to a repeating groups, and be configured between adjacent cells district intermembranous every, to prevent fertilizer crossfire in process of the test, thus affecting the accuracy of test, each repeating groups area is 13.2m2；
5., field management: in No. 1 growth stage of long agriculture round-grained rice, the Oryza sativa L. in each unit district being unified fertilising, irrigation, the process of disease pest control of weeds, and ears first 7 days long agriculture round-grained rice 1, foliage-spray sodium selenite, now leaf area is maximum, good absorbing effect；The applied amount of the sodium selenite in three cellular zones that each repeating groups comprises is identical, and the applied amount of 6 repeating groups sodium selenite is followed successively by 0g/667m2、0.5g/667m2、1g/667m2、1.5g/667m2、2g/667m2、2.5g/667m2, it is 0g/667m by the amount of spraying2Repeating groups as check plot, after Oryza sativa L. maturation gather in；
6., the mensuration to Head Rice Rate: during Oryza sativa L. maturation, measure rice yield and head rice rate, and the head rice rate of each repeating groups is compared, judge the head rice rate yield combination of each repeating groups in experimental plot, so that it is determined that step 1. experimental plot needs the selenium content used, concrete test parameters such as following table:
As seen from the above table, the head rice rate of long agriculture round-grained rice 1 is relevant with executing selenium amount, and the applied amount of sodium selenite is at 0g/667m2～2.0g/667m2Scope in, its correlation coefficient reaches pole notable level (Ra=0.935 > R0.01), at 2.0g/667m2Afterwards, then the head rice rate of Oryza sativa L. declines to some extent.This illustrates within the specific limits, by increasing the selenium consumption of long agriculture round-grained rice 1, can increase Head Rice Rate, improve Oryza sativa L. benefit.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
