Embodiment 1

[0053] Weigh respectively vine tea extract dihydromyricetin with 74.00% mass percentage, bitter almond extract with 8.00% mass percentage, mulberry root extract with 4.00% mass percentage, resveratrol with 4.00% mass percentage , 3.00% vitamin E, 3.00% vitamin C, 2.00% agricultural streptomycin sulfate and 2.00% paclobutrazol by mass are placed in a mixing tank and stirred evenly. After being packaged in a composite aluminum bag or canned, the formula product for improving the seed setting rate can be obtained.

Embodiment 2

[0055] Weigh respectively vine tea extract dihydromyricetin with 75.00% mass percentage, bitter almond extract with 7.00% mass percentage, mulberry root extract with 5.00% mass percentage, resveratrol with 4.00% mass percentage , 2.00% vitamin E, 3.00% vitamin C, 2.00% agricultural streptomycin sulfate and 2.00% paclobutrazol by mass are placed in a mixing tank and stirred evenly. After being packaged in a composite aluminum bag or canned, the formula product for improving the seed setting rate can be obtained.

Embodiment 3

[0056] Example 3: Changes in seed setting rate in seed production after spraying formula products that increase seed setting rate during hybrid rice seed production

[0057] Take by weighing 500g of the product prepared in Example 1, stir and dissolve with 50kg water to make it into an emulsion, and fill it in a plastic bucket to obtain the direct-use liquid of the formula product for improving seed setting rate of 1% by mass percentage. Spray the above-mentioned direct-use liquid once in the pollen development stage and the milky late stage in the filling stage of "Guang 8 You" and Tianyou 368" hybrid rice seed production fields, and the amount of each spraying is 50kg of direct-use liquid / mu.In addition, the contrast CK that does not spray direct liquid is set in the adjacent zone of the hybrid rice seed production field of spraying direct liquid.After the seed is mature, it is carried out the mensuration of seed setting rate.

Abstract

The invention belongs to the field of rice seeds and discloses a composition for increasing the setting percentage of rice seeds as well as a preparation method and application of the composition. Thecomposition is composed of the following raw materials in percentage by mass: 70.00-80.00% of a vine tea extract, namely dihydromyricetin, 6.00-10.00% of a bitter almond extract, 3.00-5.00% of a mulberry root extract, 3.00-5.00% of resveratrol, 2.00-4.00% of vitamin E, 2.00-4.00% of vitamin C, 1.00-3.00% of agricultural streptomycin sulfate and 1.00-3.00% of paclobutrazol. The raw materials are weighed according to the percentages, put into a blending tank, uniformly stirred and packaged with composite aluminum bags or canned, and then the composition for increasing the setting percentage ofrice seeds is prepared. The composition disclosed by the invention is reasonable, simple to process and prepare and convenient to use, and provides an ideal medicine for increasing the setting percentage of rice seeds.

Description

technical field [0001] The invention belongs to the field of rice seeds, and in particular relates to a formula for improving the seed setting rate of rice seeds, a preparation method and application thereof. Background technique [0002] The seed setting rate of rice refers to the percentage of full grains to the total number of spikelets. The level of seed setting rate can be used as one of the important reference standards for evaluating the practical application value of rice varieties, and it is also an important factor affecting rice yield. The seed-setting rate of rice is an important regulator of rice yield, and the seed-setting rate of rice varieties directly affects the yield of rice (Yang Hong et al. 2013). The formula for calculating the seed setting rate is as follows: [0003] Seed setting rate (%) = number of solid grains on rice ears / total number of grains on rice ears × 100 [0004] The period that has a greater impact on the rice seed setting rate is mai...
