Embodiment Construction

[0019] The present invention will be further explained below in conjunction with the embodiments and the accompanying drawings. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] 1. Experimental materials

[0021] Rice (Oryza sativa L.) 'Zhejing 99', 'Zhejing 100', 'Jia58', 'Zhehujing 25', 'Xiushui 121', 'Xiushui 14', 'Xiushui 134', 'Jiahua 1 Hao', 'Xiu Shui 519', 'Qian You 0508', 'Nei 5 You 8015', 'Zhe You No. 12', 'Shen You 26', 'Chun You 84', 'Chun You 927', 'Zhe You 18 '16 Seeds of Rice Varieties.

[0022] 2. Experimental method

[0023] 1. Screening of optimal conditions for seedling treatment

[0024] The seeds of 'Chunyou 927' were used as materials to explore the optimal conditions for the seedling treatment by setting gradients of seeding temperature (3) and seeding time (5) (Table 1). Specific method: Soak the seeds in clean water (tap water) in a 25°C incubator for...

Abstract

The invention discloses a method for measuring the vigor of rice seeds by soaking seeds, which comprises the following steps: placing fully water-absorbed rice seeds in a dark and sealed condition of 40°C and a relative humidity of 100% for 36 hours, then taking out the rice seeds and immediately carrying out Standard germination test, the obtained germination potential or germination rate can accurately reflect the vitality of rice seeds, and can be used to predict the emergence of rice seeds in the field. The present invention is based on the fact that it is easy to cause "suffocation" phenomenon when farmers germinate a large number of rice seeds before sowing, and innovates a new method for accurately measuring the vigor of rice seeds in a controllable room that simulates the process. Afterwards, high-temperature, high-humidity and anoxic composite stress treatment are carried out, combined with standard germination tests, the results of germination potential and germination rate can accurately reflect the vitality level of rice seeds, and the operation is simple, the controllability is good, the detection cost is low, and it is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of seed detection, in particular to a method for measuring the vigor of rice seeds through sowing. Background technique [0002] Seeds are the most basic means of production in agricultural production. The quality of seeds directly affects the safety and harvest of agricultural production, and is related to the stability and development of the entire society. Seed vigor is an important indicator of seed quality, and it is a general term that determines the potential ability of a seed or seed lot to emerge quickly and neatly under a wide range of field conditions. High-vigorous seeds are of great significance for improving the seedling rate in the field, saving sowing costs, increasing crop yield, and promoting mechanized production. [0003] At present, the methods for measuring seed vigor are mainly divided into three categories: (1) individual determinations based on germination behavior, such as germina...
