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
The invention belongs to agrochemical field, particularly relate to the regulation and control of growing of plant, specifically a kind of with oligochitosan or oligochitosan derivative be main active substances wheat increase yield compound preparation and application method thereof.
Background technology
In agriculture production, increasing the yield per unit area is the primary goal of wheat planting.And affect the many factors of wheat yield, comprising: the too high meeting of soil salt produces salt damage to wheat; Arid, hot dry wind, makes wheat wilt withered; Early the winter, cold spell in later spring can make the dead seedling of wheat frostbite serious; Disease and pest can make wheat catch an illness, and above various abiotic and biotic all can make wheat yield even have no harvest.
The Technology development improving wheat yield in current actual production comprises breed breeding, and improve vegetative storage level, moderate control is nourished and grown, and ensures good agro-farming envrionment conditions and application growth regulator and micro-fertilizer etc.
Wherein the process of breeding high-yield amount kind is complicated, and cost is high, and genetic stability is poor, and is easily subject to the impact of environmental factors, causes final tiller effect and expection to have larger gap.With the stylish research field relating to genetically modified crops wide in variety, social recognition degree is low.
By regulating liquid manure to improve wheat vegetative storage, the soil that selection soil fertility is high, nitrogen phosphorus enriches, soil moisture content is enriched or input fertilizer carry out planting the output that can improve wheat.But China's agriculture plantation water conservancy projects weak foundation and soil fertility much barrenr, organize agricultural tillage not easily to realize efficiently.
By preparations such as applied chemistry agricultural chemicals and micro-fertilizer, to improve wheat growth state, photosynthesis can also be promoted, improves output in actual production.But chemical regulator there will be saline Land, disease and pest resistance improves, the side effects such as food safety reduction.
Compared with improving the means of wheat yield above, the wheat growth conditioning agent of green high-efficient is used to demonstrate obvious advantage.Application wheat growth conditioning agent can promote that wheat is to the absorption of nutrient, stimulating growth, improves the output of wheat.
And promotion wheat increase yield the effect of increasing income can be played, the non-harmful plant-growth regulator there be limited evidence currently of of environmental protection again.
