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, durable effect, and the like; and with the application of the compounding preparation to carry out spray, seed soaking and other treatments, the wheat grain quality 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 the complex preparation of chitosan oligosaccharide or the chitosan oligosaccharide derivative improvement wheat wheat quality that is main active substances and application method thereof.
Background technology
Wheat is one of three large important cereal crops in the world, is the staple food grain of the whole world about 35% population.Wheat flour and dough have unique physical characteristic: viscoplasticity and ductility, therefore can make the numerous food such as bread, Pizza, noodles, steamed bun, cake, biscuit with water.
The quality of wheat directly affects with the quality of its food quality being raw material.But good quality wheat proportion is less in China's wheat breed, and wheat inferior, middle muscle wheat is on the high side.
The Breeding Process very poor efficiency of fine wheat varieties.The process of its seed selection fine quality is complicated, and cost is high, and genetic stability is poor, and is easily subject to the impact of environmental factor, causes final 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.
And the upper requirement of good quality wheat to soil of cultivation is higher.Good quality wheat General Requirements organic matter is abundant, well-formed, and nutrient is sufficient, and water holding capacity is strong, the soil that air capacity of soils is good.As per mu yield 400-500kg wheat, require plow layer (mellow soil layer) thickness about 30cm, the content of organic matter more than 1%, full nitrogen more than 0.06%, available nitrogen 30-40mg/kg, more than available phosphorus 20mg/kg, available potassium more than 80mg/kg.China's agriculture plantation land fertility is much barrenr, provides rich soil to organize agricultural tillage not easily to realize.
Although applied chemistry conditioning agent partly can improve wheat wheat quality, chemical regulator there will be saline Land, and damage by disease and insect pesticide resistance improves, the side effects such as foodsafety reduction.And at present production cost is low, can significantly improve wheat wheat quality and the growth regulator of environmental protection is few.
