Embodiment 1

[0032] Embodiment 1: Chitosan oligosaccharide compound preparation water preparation

[0033] Dissolve 150mg of chitosan oligosaccharide with a degree of polymerization of 2-20 and a degree of deacetylation greater than 90% in 1L of water, and at the same time add 4.5g of gibberellin, 15g of glutamic acid and 3.3g of zinc sulfate in sequence, and dissolve in sequence. Make the chitosan oligosaccharide compound preparation aqueous agent that improves wheat yield of 150mg / L.

Embodiment 2

[0034] The impact of embodiment 2 chitosan oligosaccharide compound preparation on wheat tiller number and ear grain number

[0035] 100mg chitosan oligosaccharide is dissolved in 1L water, simultaneously add 1.5g cytokinin and 5.3g zinc sulfate, 12g tryptophan successively, dissolve and make 200mg / L the chitosan oligosaccharide complex preparation aqueous agent that improves wheat output. The experiment was divided into two groups, namely the wheat treated with chitooligosaccharide compound preparation and the wheat treated with single chitooligosaccharide aqueous solution. After entering the seedling stage, start spraying and diluting the oligochitosan compound preparation and the single oligochitosan aqueous solution, once every 20 days, and the dosage per acre is 18L of aqua. The results were counted until the wheat turned green and jointed. The statistical results showed that the number of tillers and grains per ear of wheat treated with the chitosan oligosaccharide comp...

Embodiment 3

[0039] Embodiment 3 Phosphorylated chitosan oligosaccharide compound preparation seed-dressing treatment of wheat seeds improves the yield of wheat

[0040] In this test, 1 L of phosphorylated chitosan with a mass concentration of 50 mg / L was used for compound preparation, which contained 1.5 g of forchlorfenuron, 10 g of zinc sulfate, and 15 g of tyrosine. 1 kg of wheat is treated with seed dressing. The test object is wheat of Xinong 9871 variety. At the maturity stage of wheat, the number of ears, number of grains per ear and thousand-grain weight were measured, and a control group of the same variety and the same proportion of water seed dressing was set up to compare the application effect of the phosphorylated chitosan oligosaccharide compound preparation. The experimental results showed that the number of ears of wheat increased by 5.4%, the number of grains per ear increased by 1.71%, and the thousand-grain weight and yield increased by 3.9% and 6.8% respectively afte...

Abstract

The present invention discloses a chitosanoligosaccharide compounding preparation having a wheat yield increasing effect. The chitosanoligosaccharide compounding preparation is characterized by comprising, by weight, 0.005-0.02% of chitosanoligosaccharide or a chitosanoligosaccharide derivative, 0.1-5% of amino acids, 0.3-1.2% of trace elements, 0.02%-0.5% of a plant growth regulator, and the balance of a solvent or carrier. The present invention further provides a method for using the compounding preparation to improve the wheat yield. According to the present invention, the chitosanoligosaccharide in the compounding preparation is saccharide molecules formed by connecting two or more glucosamine through a glycosidic bond, and the agent adopting the chitosanoligosaccharide and the chitosanoligosaccharide derivative as the main component has advantages of safety, no toxicity, environmental protection, broad and durable effect, and the like; and with the application of the compounding preparation to carry out spray, seed soaking and other treatments, the wheat yield can be significantly increased, and the cost is significantly lower than the cost of the similar products.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to the growth and development regulation of plants, in particular to a compound preparation for increasing wheat yield with oligochitosan or oligochitosan derivatives as the main active substance and its application method. Background technique [0002] In agricultural production, increasing the yield per unit area is the primary goal of wheat cultivation. There are many factors that affect the yield of wheat, including: high soil salinity will cause salt damage to wheat; drought, dry and hot wind will make wheat wilt and wither; early winter and late spring cold will cause serious frostbite and dead seedlings of wheat; Various abiotic and biotic stresses can reduce or even eliminate wheat yields. [0003] At present, the conventional treatment techniques for improving wheat yield in actual production include variety selection, improving nutrient storage level, mod...
