Embodiment 1

[0015] Example 1 The hybrid rice combination Y Liangyou No. 1 hybrid seed production effect of using this mixed-type panicle germination inhibitor.

[0016] 1. In 2012, a hybrid farming experiment was carried out in Dongxiang Town, Zixing County, Chenzhou City, Hunan Province. Before the middle stage of seed ripening, all field management was in accordance with the conventional management of rice hybrid farming.

[0017] 2. In the middle stage of seed curing, draw 9 blocks in the same lot, 0.5 mu / block, set 3 treatments, and repeat 3 times / treatment. Process I: spray the mixed type anti-ear germination agent of the present invention in the following manner; process II (contrast 1): spray the vertical harvesting grain by the instructions for use of the vertical harvesting grain (Diquat) of Syngenta Crop Protection Co., Ltd. of Switzerland ; Treatment III (control 2): ​​untreated seed production field.

[0018] 3. Add 4 to 6 drops of surfactant Tween 80 in every liter of the m...

Embodiment 2

[0023] In 2013, in Tongjinpu Town, Cili County, Zhangjiajie City, Hunan Province, the hybrid planting field of II You 1681 was selected and the same test was carried out in the above-mentioned manner. The mixed germination inhibitor was harvested on the same day as the control, the water content of the seeds was measured after spraying, and the germination rate and thousand-grain weight of the seeds were measured after harvesting. After spraying this mixed type anti-ear germination agent, there is no continuous rainy weather. The results showed that the water content of the seeds was reduced to 27.5% on the 3rd day after spraying this mixed type anti-ear germination agent, and the water content of the seeds was reduced to 18.6% on the 5th day; The water content of the seeds decreased to 28.6% from the 3rd day, and decreased to 22.5% on the 5th day; while the water content of the seeds in the untreated seed production field was always about 30%. The germination rate of seeds s...

Abstract

The invention provides a method for inhibiting the germination of seeds on rice spikes and provides main components, a formula and an application method of a mixed type spike germination inhibiting agent. The application method comprises the following steps: from a middle soft dough stage to an initial yellow ripe stage of rice seeds, spraying the mixed type spike germination inhibiting agent at sunny days or non-rainy days; before spraying, adding 2-6 drops of a surfactant, such as Tween 80, into each liter of the mixed type spike germination inhibiting agent, and uniformly shaking; spraying 20-30 liters of the mixed type spike germination inhibiting agent into each Mu of a rice crossbreed seed farm; and uniformly spraying the mixed type spike germination inhibiting agent on rice spike layers.

Description

technical field [0001] The invention belongs to the field of rice seed production, in particular to a method for inhibiting seed germination on rice panicles. Background technique [0002] Generally speaking, about 10 days after rice pollination ends, most of the embryos of the seeds have been fully developed and have the ability to germinate. However, during the maturity stage of rice seeds, sometimes continuous rainy weather will cause the moisture content of the seeds to be high, and the temperature during the maturity stage will also be high, so that the seeds are under high temperature and high humidity conditions, causing the seeds to germinate on the ears of rice before they are harvested. Or germination, greatly reducing the quality of seeds, causing greater losses to seed production enterprises. Therefore, by adopting a certain method to reduce the moisture content of the mature harvest period of the seeds, the moisture content of the seeds cannot reach the minimum...
