Embodiment 1

[0036] A drought-tolerant seed coating agent for rapeseed, made of the mass fractions of the following raw materials: 22.5 grams of ammonium polyacrylate, 7.5 grams of potassium acrylate, 0.1 grams of abscisic acid (ABA), 0.1 grams of strigolactone, and 2.5 grams of chitosan gram, 3.5 grams of trehalose, 0.8 grams of crosslinking agent (curing agent S-80), 3.5 grams of sodium lauryl acid, 12.0 grams of starch, and the remainder being 47.5 grams of distilled water.

[0037] The preparation of the present invention is prepared by mixing the above-mentioned raw material components in proportion. Get 500ml of the preparation of the present invention for every 10kg of rapeseed, and dress the seeds before sowing the rapeseed. Using Zhongyouza 12, a rapeseed variety bred by the Research Institute of Oil Crops, Chinese Academy of Agricultural Sciences, as the test variety, the results of the comparison between the effect after seed dressing and the untreated control are as follows:

Abstract

The invention discloses a drought-enduring seed coating agent of oilseed rape. The drought-enduring seed coating agent of the oilseed rape is prepared from the following raw materials in percentage bymass: 20.0-30.0% of ammonium polyacrylate, 6.0-10.0% of potassium acrylate, 0.05-0.5% of abscisic acid (ABA), 0.05-0.5% of strigolactone, 1.0-5.0% of chitosan, 3.0-5.0% of trehalose, 0.5-1.5% of cross-linking agent (vulcanizing agent S-80), 3.0-5.0% of sodium dodecyl sulfate, 10.0-20.0% of starch and 22.5-56.4% of distilled water. The coating agent is reasonable in formula and convenient to use and can improve the drought resistance of a whole growth period of the oilseed rape furthest; meanwhile, due to the fact that an induction factor special for the oilseed rape adversities resistance isadded into a preparation, the resistance of the oilseed rape to drought stress can be effectively induced, expression of corresponding drought resistance genes is activated, and the drought resistanceof the whole growth period of the oilseed rape is promoted; therefore, compared with ordinary seed drought-enduring coating agents, the preparation has the advantages that action is direct, the yieldimprovement effect is significant, an economic coefficient is high, the effect is durable, and the like.

Description

technical field [0001] The invention belongs to the field of bioengineering, and more specifically relates to a coating agent for rapeseed drought-tolerant seeds. Background technique [0002] Drought is one of the important factors limiting the production and development of rapeseed. The Yangtze River Basin is the main rapeseed producing area in China. Although there is abundant rainfall, the distribution of precipitation is uneven throughout the year, and seasonal droughts occur frequently. In recent years, with global climate warming, autumn droughts in the Yangtze River Basin in my country have become more frequent. In spring rapeseed area, drought is one of the most important limiting factors affecting rapeseed production. According to statistics, the average annual reduction in rapeseed output due to drought reaches more than 15%, and in severe years it reaches more than 30%. For rapeseed, drought damage may occur in autumn, winter and spring and affect yield. Autu...
