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 present invention relates to the field of rice seeds, and discloses a formulation for increasing the seed setting rate of rice, a preparation method therefor and use thereof. The formulation is made from the following raw materials by mass percentage: 70.00 to 80.00% of a vine tea extract dihydromyricetin, 6.00 to 10.00% of a semen armeniacae amarae extract, 3.00 to 5.00% of a mulberry root extract, 3.00 to 5.00% of a resveratrol, 2.00 to 4.00% of vitamin E, 2.00 to 4.00% of vitamin C, 1.00 to 3.00% of agricultural streptomycin sulfate, and 1.00 to 3.00% of paclobutrazol. The raw materials are weighed according to the described ratio, placed into a mixing tank, stirred until uniform, and packaged with a composite aluminium bag or tank, so as to obtain the formulation for increasing the seed setting rate of rice. The present invention has the advantages of reasonable formulation, simple processing and convenient use, providing an ideal medicament for increasing the seed setting rate.

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...
