Embodiment 1

[0044] In order to specify the implementation process of the present invention, the following raw materials are purchased from the agricultural materials market for the preparation of rapeseed growth regulator:

[0045] A. Gibberellin: soluble powder (GA3 content 40%), produced by Jiangsu Fengyuan Bioengineering Co., Ltd.;

[0046] B. Boron fertilizer: instant boron fertilizer (B>20.5%), produced by Wuhan Hezhong Biochemical Manufacturing Co., Ltd.;

[0047] C. Dipotassium hydrogen phosphate: produced by Qingzhou Xinsheng Chemical Co., Ltd., the active ingredient of dipotassium hydrogen phosphate is >95%;

[0048] D, imidamide: 50% EC, produced by Henan Chunguang Agrochemical Co., Ltd.;

[0049] There are many similar agricultural materials products on the market, and you can also choose products from other manufacturers without affecting their application effect.

[0050] Described boron fertilizer mainly contains boric acid and borax. Boron is one of the essential nutrien...

Embodiment 2

[0066] A high-efficiency rapeseed growth regulator, which is prepared by mixing the following raw materials according to mass percentage:

[0067]

[0068] Its preparation method is identical with embodiment 1. This experiment was carried out in Yangluo Town, Xinzhou District, Wuhan City, Hubei Province. The rape variety used was Sunshine 2009. The test area was 20 mu, of which 10 mu were sprayed with rapeseed growth regulator once at the final flowering stage, and the other 10 mu was used as a control , investigate the incidence of sclerotinia, lodging resistance at the mature stage, and measure the actual yield. The results showed that the average yield of Sunshine 2009 after spraying the growth regulator was 230.5 kg / 667m 2 , increased yield by 18.9% compared with the control, and the oil content was 45.2%, which was 1.6 percentage points higher than the control; the thousand-grain weight was 4.0g, which was 12% higher than the control; the incidence of Sclerotinia was ...

Embodiment 3

[0070] A high-efficiency rapeseed growth regulator, which is prepared by mixing the following raw materials according to mass percentage:

[0071]

[0072] Its preparation method is identical with embodiment 1. The experiment was carried out in Sanhua Town, Xishui County, Hubei Province in the spring of 2011. The rape variety used was Zhongshuang 12, and the demonstration area was 150 mu, of which 100 mu was sprayed with rapeseed growth regulator once during the budding stage. Re-spray once at the final flowering stage, and the other 50 acres are used as a control, and the actual yield is measured at the mature stage. The results showed that the average yield of Zhongshuang 12 after spraying the growth regulator was 216.8 kg / 667m 2 , 28.9% more yield than the control, basically no lodging phenomenon (the control is mild lodging), and the ripening period is 4 days earlier than the control. This year, because the spring rain is more, the growth of other rapeseed varieties i...

Abstract

The invention discloses a rape growth regulator and a preparation method thereof. The high-efficiency rape growth regulator is prepared by compounding four raw materials, i.e., gibberellin (GA3), quick-acting boron, potassium dihydrogen phosphate (KH2PO4) and prochloraz, according to a certain proportion. The preparation method comprises the following steps of: A, fully and uniformly mixing the GA3, a boron fertilizer and KH2PO4 at normal temperature; and B, fully and uniformly mixing the mixed drug prepared by the step (A) with the prochloraz at the normal temperature to obtain the rape growth regulator. A product obtained by the invention has the advantages of convenience in use, low cost, simple method, easiness and convenience in operation and high benefit and is a pollution-free rape growth regulator. The product has a function of obviously promoting growth and development of rape, has the effects of preventing flowering without seed, premature senility and high temperature forced ripening and increasing pod number and thousand seed weight and the like and realizes production increase of rape of 8-40 percent.

Description

technical field [0001] The present invention relates to plant growth regulator GA3 (gibberellin) and plant regulator substance KH 2 PO 4 (potassium dihydrogen phosphate), more specifically relates to a high-efficiency rapeseed growth regulator, and also relates to a preparation method of a high-efficiency rapeseed growth regulator, which is suitable for improving the disease resistance, stress resistance and high yield of Chinese rapeseed. Background technique [0002] China is a major producer of rapeseed, with a perennial planting area of ​​110 million mu of rapeseed and a total output of 11.9 million tons. The area and total output account for one-third of the world's total, ranking first in the world. The unsaturated fatty acid content of double-low rapeseed can reach more than 90%. It is one of the healthiest edible vegetable oils for human beings, accounting for nearly 40% of the total edible vegetable oil production in China. The development of rapeseed production is...
