Problems solved by technology

However, the lag in basic theoretical research of ratooning rice has seriously affected its yield potential. Therefore, it is urgent to conduct systematic research on key technologies for the regulation of ratooning rice yield formation and develop key technology systems that can regulate the production of ratooning rice.
At this stage, there are few reagents on the market that can promote plant tiller bud differentiation, and the effects of promoting plant tiller bud differentiation on different plants are different. Therefore, finding new substances to regulate rice regeneration has become a possible solution

Embodiment 1

[0030] Example 1 Influence of rice piling height on different rice seed setting rates

[0031] Two rice varieties, "Meixiangzhan No. 2" and "Guangdong Nong Simiao", were cut from the rice ears and planted in cement buckets filled with paddy soil, with 2 plants per bucket, and a total of 100 buckets were planted. After transplanting the slow seedlings, the rice was piled with different heights (15cm, 30cm, 50cm). Spraying was carried out with a solution of fluridone at a concentration of 30 μM. The control group was sprayed with the same amount of water. After spraying the fluoridone solution, photographs were taken of the rice with different piling heights, and photographs were taken every 7 days until the regenerated rice was mature.

[0032] The experimental results are as Figure 1-6 shown, figure 1 For the results of the effect of fluridone on the pile height of Meixiangzhan No. 2 regenerated rice, from figure 1 It can be seen from the above that fluridone has obvious...

Embodiment 2

[0033] Example 2 The effect of fluridone spraying concentration on the number of tiller buds in rice

[0034] The rice ears of 2 rice varieties "Meixiangzhan No. 2" and "Guangdong Nong Simiao" were selected, and the 30cm rice stubs were planted in cement buckets filled with paddy soil, 2 plants per bucket, a total of 2 plants. 30 buckets were planted and sprayed with fluridone solution (concentrations of 10 μM, 30 μM, 50 μM, 90 μM), and the control group did not receive any treatment. After spraying the fluoridone solution, photographs were taken of the rice with different piling heights, and photographs were taken every 7 days until the regenerated rice was mature, and the average number of new tiller buds per rice was recorded.

[0038] The experimental results are shown in Table 1. Table 1 shows the effect of the average number of new tiller buds on Houmeixiangzhan No. 2 and Yuenong silk seedlings sprayed with different concentratio...

Embodiment 3

[0039] Example 3 paddy field experiment

[0040] On the basis of laboratory tests, the experiments were carried out after harvesting the first season rice using two varieties of rice, "Meixiangzhan No. The way of cell separation is adopted, and the height of the pile is 30cm. Fluridone reagent was used for spraying at a concentration of 30 μM, and the amount of fluoridone solution sprayed was 20 liters / mu, and the control group was sprayed with clean water.

Abstract

The invention discloses the application of fluridone in promoting rice tiller bud differentiation and regenerating rice planting. The fluridone can be used to promote the growth of regenerated rice and the differentiation of rice tiller buds, has a regulating effect on the growth of regenerated rice, has little environmental pollution, can effectively reduce the occurrence of rice diseases and insect pests, and can be widely used in different regions. , In the planting of regenerated rice of different rice varieties, it has obvious effect of increasing panicle and yield.

Description

technical field [0001] The invention belongs to the technical field of crop production, in particular to the application of fluridone in promoting differentiation of rice tiller buds and planting of regenerated rice. Background technique [0002] Regenerative rice is a rice cropping mode that utilizes the rice stumps after the first season of rice is harvested, and takes certain management and cultivation measures to make the dormant tiller buds on the rice stumps quickly germinate into seedlings, heading and fruiting and harvesting again. When rice is mature, some tiller buds usually exist on several nodes at the base. After the first season is harvested, the tiller buds of the rice stubs grow and head again, and they mature and harvest again after about 2 months of growth and development. Regenerated rice has the advantages of short growth period, saving seeds, saving labor, regulating labor, saving cost, saving water, making full use of light and temperature resources and...
