According to the technical scheme, compared with the prior art, the method for screening the variety of the ratooning rice based on the runoff quantity is disclosed, the runoff quantity attenuation rate is calculated by adopting the same cultivation management measures for different varieties of the ratooning rice and combining a convenient runoff quantity sampling method at a specific time, the regeneration capacity of the existing variety of the rice is evaluated according to the attenuation rate, only the first-season sampling analysis is needed, the regeneration capacity can be evaluated at the same time of the existing variety production test of the rice, the screening evaluation of the ratooning rice is not needed, the workload is greatly reduced, and the production application of the ratooning rice is promoted to be accelerated.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The test is carried out in the village under the Mesona town of Yuxi county of Fujian province, the test land is convenient to drain and irrigate, and the land capability is moderate. The test materials are Luyou Ming, shenliangyou 856, shenyou 9529, taifengyou 656 and Guyou 2736, and the area of the cell is 70m 2 And (4) designing a random block.
Applying special fertilizer (N-P) for rice before all treatments and transplants 2 O 5 -KO 2 = 12-5-8) 40kg, 5kg potassium chloride as base fertilizer; 7d after transplanting every 667m 2 Applying 40kg of special rice fertilizer as tillering fertilizer, wherein the jointing period is every 667m 2 Application of composite fertilizer (N-P) 2 O 5 -KO 2 = 15-15-15) 12.5kg as spike fertilizer; each 667m of young ear differentiation at VI stage 2 And 7.5kg of compound fertilizer is applied as a grain protection fertilizer. Each 667m of regeneration season 2 Applying 25kg of urea, and applying 5kg of urea respectively 15 days before harvesting the first season rice and 10kg of urea respectively 5 days and 10 days after harvesting.
Under the condition that the standards of cultivation management measures are consistent, draining water in the field in the head season and the head harvest period and the physiological maturity period of rice, preferably not sinking by foot, continuously selecting 10 plants before 6 points in the morning on a sunny day, cutting off the plants at a place 20cm away from the field surface, placing absorbent cotton (the absorbent cotton is weighed in advance and the initial weight is recorded) at the cutting and stopping place, then wrapping and tightening the absorbent cotton by a plastic bag, collecting the absorbent cotton after 1 hour, immediately weighing, and subtracting the initial weight of the absorbent cotton from the measured weight to obtain the bleeding wound (g/h) of each plant.
Calculating the loss attenuation ratio ER = (W) h -W m )/W h
Wherein, W h : impairment flow rate in the full heading period; w m : flow impairment during maturation.
As shown in tables 1-3, the regeneration season yield of Luyou Ming, shenliangyu 856, shenyou 9529, taifengyou 656 and Guyou 2736 is not obviously related to the injury flow rate in the full heading period or the injury flow rate in the mature period, but is closely related to the injury flow rate decay rate, regression analysis shows that the two are linearly related, and the regression equation is as follows:
Y＝-644.01x+513.21(R 2 ＝0.957 ** )
calculating according to a regression equation to obtain that the yield of the rice variety with the bleeding injury attenuation rate lower than 48.63 percent in the regeneration season is not lower than 200kg; the yield of the rice variety with the bleeding injury attenuation rate lower than 33.11 percent in the regeneration season is not lower than 300kg.
The yield potential of different varieties in the regeneration season can be predicted according to the bleeding rate attenuation rate, so that the regenerated rice varieties can be accurately screened and evaluated.
