Problems solved by technology

[0002] The rice lodging problem has always been one of the limiting factors that plague rice production. Due to the existence of lodging, the service life of fine varieties has been shortened. Although breeders have been trying to improve the lodging resistance of rice in recent years by reducing the plant height, but at present From the point of view, the effect is not obvious. This is because the biological yield of rice is limited after the plant height is reduced, which in turn limits the further increase of rice yield. Especially at present, the yield per unit area of ​​rice has been hovering. This breeding trend is not good for the breakthrough of rice yield of
[0003] Rice lodging resistance is affected by many aspects. The lodging resistance evaluation method currently used in breeding only considers the lodging resistance of the rice variety itself, ignoring the influence of other factors on the lodging resistance of rice. It is very one-sided. At the same time, each measurement method is relatively cumbersome, and it is impossible to measure the lodging resistance of varieties in large quantities.

Embodiment Construction

[0021] A method for evaluating rice lodging resistance, comprising the steps of:

[0022] S1 square box standardization process: the length, width and height of the square box are 10:4:5 respectively, the soil is added from the same source, and the measured soil fertility is consistent. Before adding, it needs to be dried and the measured water content is consistent. When adding, it needs to be based on the experiment. Weighing is required. All the soil used in the experiment has the same weight when added to the box, the weight of the water added to the box is the same, and the type of fertilizer applied is the same, and the weight is the same, so as to ensure that the conditions in the box used in the experiment are consistent and eliminate errors.

[0023] S2 Establish a lodging resistance detection greenhouse: the greenhouse is a rectangular greenhouse with an aspect ratio of 10-20:1. The greenhouse is a fully enclosed glass greenhouse. The long side of the greenhouse is eq...

Abstract

The invention discloses a rice lodging resistance evaluation method, which comprises the following steps: square box standardization treatment, measurement of variety transplanting, ear trimming at the filling stage, transfer to a detection greenhouse for detection, and measurement of the inclination degree of the treatment variety. The present invention is controlled by experimental conditions, so that the conditions of all measured varieties are uniform, and experimental errors are avoided; the present invention utilizes the greenhouse to install simulated rainfall and wind blowing devices to realize various natural conditions that lead to lodging; the present invention measures varieties in single row planting, The ear clipping treatment ensures that the detection result reflects the lodging resistance of the variety itself; the present invention uses the treated plant inclination angle as the detection index of the lodging resistance, which is simple to operate and convenient for large-scale determination of the lodging resistance of the variety.

technical field [0001] The invention relates to the field of rice planting, in particular to a method for evaluating rice lodging resistance. Background technique [0002] The rice lodging problem has always been one of the limiting factors that plague rice production. Due to the existence of lodging, the service life of fine varieties has been shortened. Although breeders have been trying to improve the lodging resistance of rice in recent years by reducing the plant height, but at present From the point of view, the effect is not obvious. This is because the biological yield of rice is limited after the plant height is reduced, which in turn limits the further increase of rice yield. Especially at present, the yield per unit area of ​​rice has been hovering. This breeding trend is not good for the breakthrough of rice yield of.
