Problems solved by technology

Analyzing the main components and effects of this patent, it can be found that abscisic acid plays a major role in this preparation, and its content is 0.3g-1.5g / L, and the effect is best with a content of 0.9g / L. The dosage per mu of wheat is 100ML, and the yield is increased by 10.34%. Increase the yield of wheat by 20.68-46.53kg / mu, and increase the benefit by 48-107 yuan (the price of wheat is 2.3 yuan / kg), while the cost of abscisic acid per mu of preparation is about 100 yuan, and there are other components. The cost of increasing production is low Due to the cost of preparation application, its wide promotion is limited
In short, there is currently a lack of biochemical preparations or products that are stable and outstanding, easy to use, and low in cost for resisting dry and hot wind of wheat. Therefore, it is necessary to develop wheat anti-dry and hot wind preparations and conduct rigorous experiments to verify their application effects

Embodiment 1

[0030] Powdered anhydrous calcium chloride 50% (18% for pure calcium), calcium urea acetylsalicylate 1.661%, sodium nitrophenolate 0.25%, biochemical fulvic acid powder 48.1%, mix according to the above ratio, fully stir and mix , bagged and named Kn-2 preparation.

Embodiment 2

[0031] Example 2 Effect of Kn-2 on wheat seed germination under artificially simulated drought stress conditions

[0032] Dilute the Kn-2 preparation 200 times at room temperature at 20°C and soak the seeds for 12 hours. After drying, conduct a germination test on the seeds in a light incubator to simulate drought stress with PEG, and clean water is CK. Put the processed seeds into a petri dish, add 3mL concentration of -0.5MPa 19.2% PEG-6000 solution, count the germination potential, germination rate and relative germination rate of each treatment on the 3rd and 7th days of cultivation; Shoot length, primary root number and primary root length.

[0033] The results showed that the germination potential, germination rate, relative germination rate, primary root length and shoot length of wheat were improved or increased in different degrees after soaking seeds with Kn-2 formula. It shows that soaking seeds with Kn-2 preparation under drought stress improves the ability of see...

[0037] Example 3 Effect of Kn-2 formulation on thousand-grain weight and yield at the jointing stage of wheat, grouting and spraying (2012)

[0038]Spray 500 times of Kn-2 preparation once at the jointing stage and filling stage of wheat, set the same amount of water as CK, the tested variety: Shunmai 1718, and the location: Niujiaao Farm, Xia County, Cotton Research Institute, Shanxi Academy of Agricultural Sciences.

[0039] The results showed that the thousand-grain weight and yield of wheat sprayed with Kn-2 formula were higher than those of CK, which indicated that Kn-2 formula had better resistance to dry and hot wind. The results are shown in Table 2.

Abstract

The invention discloses a wheat anti-dry hot wind preparation, which comprises water-soluble calcium salt, calcium urea acetylsalicylate, biochemical fulvic acid and sodium nitrophenolate. The present invention selects four kinds of components with good water solubility and different anti-stress mechanisms for scientific compatibility, overcomes the disadvantage of unstable drug effect of a single component in the past, and has simple preparation, good water solubility, convenient use and remarkable effect. The raw material components are not only plant stress regulators, but also plant organic nutrition and medium element nutrition, which can stabilize the biofilm structure, reduce transpiration, improve the dehydration resistance of wheat leaves, improve cell vitality, and enhance pollination ability. , Promote photosynthesis, prevent premature aging, increase source and increase library and other properties. After wheat is used, it can maintain the normal growth and development metabolic level and balance of the plant, effectively enhance the ability of wheat to resist dry and hot wind, promote wheat grain filling, increase wheat thousand-grain weight and yield, and use it at and before poplar flowering stage can also increase the number of grains per ear.

Description

technical field [0001] The invention relates to a preparation for resisting dry hot wind of wheat. Background technique [0002] The wheat planting area in the Huanghuaihai region of my country accounts for 68% of the total wheat area in the country, and the output accounts for 76% of the total wheat output in the country, ranking first in the country. [1] . This wheat area is not only the main producing area of ​​winter wheat in my country, but also the area most seriously damaged by dry and hot wind. For example, Henan Province, the province with the largest wheat planting area in my country, analyzed the occurrence of dry and hot wind in the past 30 years from 1967 to 1996. The annual average number of days of dry and hot wind in Henan Province was 0.5 to 3.9 days, and the annual average number of dry and hot winds was 0.4 to 0.9 times. That is, the probability of occurrence is 4 to 9 cases in 10 years [2] . After the wheat is harmed by the dry hot wind, all parts lose...
